▼ Pseudomonas aeruginosa é uma importante causa de infecções apresentando, no Brasil, altas taxas de morbidade e mortalidade. Os principais mecanismos de resistência utilizados por P. aeruginosa são a produção de β-lactamases e a expressão de bombas de efluxo. O uso de IgG e antibióticos para tratamento destas infecções tem apresentado resultados bem sucedidos, o que motiva a realização de estudos quanto a atividade in vitro da IgG humana com antibióticos frente a isolados de P. aeruginosa. O objetivo deste estudo foi detectar a presença dos genes de resistência, a relação clonal, o tempo de morte em isolados de P. aeruginosa provenientes de Infecções relacionadas à saúde (IrAS) de hospitais públicos do Recife-PE, em 2014, e verificar in vitro a taxa de fagocitose e a produção de oxido nítrico (NO) por monócitos humanos quando infectados por P. aeruginosa tratada com IgG humana em associação a Meropenem e Polimixina E. Foram avaliados 32 isolados para a detecção de genes de resistência por PCR, e para a avaliação de similaridade genética por ERIC-PCR. Destes, foram selecionados os 5 isolados apresentando maior número de genes de resistência e menor similaridade genética. Esses cinco isolados foram submetidos às associações dos sub-CIMs destes antibióticos com a IgG humana, para a determinação do tempo de morte, da taxa de fagocitose de células bacterianas e para a dosagem de NO por monócitos humanos. Foi detectado a presença do gene blaKPC em dois isolados de P. aeruginosa. Todos os isolados possuem os genes mexR, mexB, mexE e rpsL, apenas um isolado foi negativo para os genes mexA e mexF. Foram detectados 30 perfis genéticos distintos entre os isolados bacterianos. O tempo de morte dos isolados revelou que os tratamentos combinados com antibióticos, principalmente Polimixina E, são mais letais para as células bacterianas. A taxa de fagocitose por monócitos humanos revelou que quando infectados com bactéria tratada com IgG mais antibiótico, os monócitos ficam mais ativos à fagocitose e reduz drasticamente a quantidade de células bacterianas. Houve diferença significativa na produção de NO naqueles tratados com Meropenem e IgG. Com o presente estudo concluiu-se que a combinação de IgG mais antibiótico pode ser uma alternativa para o tratamento dessas infecções, pois a bactéria estará em número reduzido facilitando a fagocitose.

▼ Abstract: Polyclonal human G immunoglobulins are widely applied in therapeutic treatments for cancer, autoimmune diseases and immunodeficiency and in the analytical area of diagnostic testing. The human IgG Fab fragments can be obtained via enzymatic cleavage of the native molecule or recombinant DNA technology. The Fab is composed of constant regions (CL and CH) and variable (VL and VH). The variable regions of the light and heavy chains comprise the Fv fragment. Fab fragments and Fv fragments were cited as second and third generation of antibodies, respectively, and has been an increasing interest in employing them in therapeutic treatments, as both have molecular weight less than the intact IgG and preserve the affinity for the antigen. The applied these proteins in therapy and analytical investigation require a high degree of purity, so, different purification strategies have been developed. In order to contribute to the development of Fab fragment purification processes, we studied the use of alternative biospecific binding to proteins A, G and L, commonly applied for this purpose. In this work, the purification of the Fab fragments was performed by affinity chromatography with chelated metals (IMAC) and phenyl and boronate (PB) ligand immobilized on agarose gel. In this investigation, the metal chelates Cu 2+, Ni 2+ and Co 2+ were studied when tested in IDA (iminodiacetic acid) and TREN (Tris 2 (aminoethyl) amine) and buffer system Tris-HCl, sodium phosphate and HEPES with or without NaCl for purification of Fab fragments from enzymatic cleavage solution of polyclonal human IgG. The results of Western blot and radial immunodiffusion were analyzed together. For the purity of the Fab fragments obtained in flowthrough, the increasing order was obtained TREN-Ni2+ (100%) > IDA-Ni2+ (88.6%) > IDA-Co2+ (71.1%) > IDA-Cu2+ (63.9%). In relation to yield, we obtained the following order: TREN-Ni2+ (86.2%) = IDA-Co2+ (86.2%) > IDA-Ni2+ (74.3%) = IDA-Cu2+ (73.7% ). With regard to the total capacity protein adsorption per ml of gel, was obtained the order 14.3 mg mL-1 (TREN-Ni2+) > 11.2 mg mL-1 (IDA-Ni2+) > 5.65 mg ml -1 (IDA-Cu2+) > 4.3 mg ml-1 (IDA-Co2+). The binder FB adsorbed Fab and Fc did not cause separation thereof. This work led us to conclude that the chelating agents IDA and TREN with the metal ions used, enable separate the Fab fragments of Fc fragments and get them with satisfactory degree of purity Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Bueno, Sônia Maria Alves, 1961- (advisor), Bueno, Sonia Maria Alves (advisor), Universidade Estadual de Campinas.

L'anaphylaxie est la manifestation clinique la plus sévère de l’allergie. Il est couramment admis que chez l’homme, l’anaphylaxie est médiée par les anticorps de type IgE. Cependant, des données chez la souris indiquent que les IgG peuvent également contribuer à l’anaphylaxie. Le but de ma thèse a été de mieux comprendre comment les IgG induisent l’anaphylaxie. Dans un premier temps, nous avons démontré que les IgG murines induisent l’anaphylaxie en activant le récepteur FcγRIII à la surface des macrophages, ce qui aboutit à la libération de PAF. Nous avons ensuite voulu savoir si les IgG humaines peuvent également induire des chocs anaphylactiques. L’anticorps thérapeutique Omalizumab (IgG1 humanisée anti-IgE) induit des chocs anaphylactiques chez certains patients. Nous avons démontré que Omalizumab forme des complexes immuns qui peuvent activer les récepteurs FcγRs et induire des chocs anaphylactiques dans des souris exprimants les FcγRs humains (hFcγRKI). Nous avons ensuite développé une version mutante d’Omalizumab incapable de lier les FcγRs et démontré que cet anticorps bloque les IgE sans induire d’anaphylaxie. Finalement, nous avons développé un nouveau modèle humanisé d’anaphylaxie aux arachides dans lequel les souris hFcγRKI sont sensibilisées avec des IgG de patients allergiques aux arachiques. Nos données préliminaires indiquent que les IgG peuvent induire l’anaphylaxie dans ce modèle. De manière surprenante, l’anaphylaxie est augmentée dans des souris n’exprimant aucun FcγR. Nous étudions actuellement le(s) mécanisme(s) responsables de cet effet, et notamment l’implication de la voie du complément et le rôle du récepteur inhibiteur FcγRIIB.

Anaphylaxis is a severe and potentially fatal allergic reaction. The current paradigm in humans states that anaphylaxis is triggered by allergen-specific IgE antibodies (Abs). Several reports in mice indicate that IgG Abs can also trigger anaphylaxis. The goal of my thesis was to better understand the pathways through which IgG mediate anaphylaxis. We first evaluated this in an adjuvant-free mouse model of active systemic anaphylaxis. We observed a contribution of the 'classical’ pathway mediated by IgE, FcγRI, mast cells and histamine. However, anaphylaxis was largely mediated by an ‘alternative’ pathway driven by IgG, FcγRIII, macrophages and PAF. We then examined whether human IgG can also trigger anaphylaxis. Omalizumab, an IgG1 anti-IgE mAb, has been reported to induce adverse events, including anaphylaxis. We found that Omalizumab forms immune complexes with IgE that engage FcγRs and induce both skin inflammation and anaphylaxis when injected into mice expressing all human FcγRs (hFcγRKI). We then developed an Fc-engineered version of Omalizumab which cannot bind FcγRs, and demonstrated that this Ab is as potent as Omalizumab at blocking IgE-mediated allergic reactions, but does not induce FcγR-mediated anaphylaxis. Finally, I describe ongoing work in a new model of peanut anaphylaxis in which hFcγRKI mice are sensitized with IgG from allergic subjects.…

▼ La preñez en los mamíferos se atribuye a la regulación del sistema inmune materno por factores placentarios. En el presente trabajo de tesis se estudió la respuesta inmune humoral durante la gestación porcina. Se procesaron 45 tractos reproductivos y se recogieron sueros, placentas y muestras de tejidos placentarios maternos y fetales de 30 días (n=17); 65-70 días (n=9) y de 96-114 (n=6) días de preñez, así como de útero no gestante (n=13). Se estudió la presencia de IgG y su receptor en tejidos placentarios por inmunohistoquímica, se determinó la concentración de Ac IgG asimétricos mediante ELISA de captura y la concentración de IgG en suero y en extractos placentarios porcinos por inmunoturbidimetría e inmunodifusión radial. Se detectó la presencia de IgG y su receptor en tejidos placentarios maternos y fetales a partir de los 30 días de gestación hasta el final de la preñez. En placenta materna se halló positividad a IgG en todos los períodos estudiados, así como en los constituyentes de la placenta fetal, particularmente en las vellosidades que conforman la interfase feto materna. Se observó expresión positiva del receptor Fc gama de las IgG durante toda la preñez, salvo en glándulas uterinas al final de la gestación. En suero no encontramos diferencias significativas en el porcentaje de Ac IgG asimétricos entre cerdas vacías y preñadas, pero sí entre los diferentes períodos gestacionales, hallando disminución de Ac IgG asimétricos a los 30 días de preñez y aumento a los 95-114 días (32±3 vs 43±3, p: 0,01). En homogenatos de placenta materna se observó la mayor concentración de anticuerpos asimétricos a los 65-70 días (x=44,62), descendiendo los valores al final de la gestación (x=13,50), mientras que en homogenatos fetales las concentraciones de Ac IgG asimétricos permanecieron constantes durante toda la preñez (x=43,54). Se encontraron diferencias significativas en suero entre cerdas vacías y preñadas en la concentración de IgG/Turb (F: 4,17 y p: 0,0483), con una disminución al final de la preñez; mientras que los valores de IgG/IDR (F: 5,16 y p: 0,0316) fueron mayores a los hallados por turbidimetría (p: 0,1278; R2: 0,22), disminuyendo también al final de la preñez. En conclusión, se halló IgG y su receptor Fc gama sobre cortes histológicos placentarios, tanto maternos como fetales, a partir de los 30 días de preñez, se postula que las IgG serían de origen materno y que por transcitosis alcanzan la interfase feto materna. Se determinó la concentración de Ac IgG asimétricos durante la gestación porcina, no hallándose en suero diferencias significativas entre cerdas vacías y preñadas, probablemente debido al tipo de placenta epiteliocorial y no invasiva que presenta esta especie. Únicamente en los homogenatos de placenta fetal se hallaron valores altos de Ac IgG asimétricos a concentraciones constantes durante la preñez. Se postula que la respuesta inmune humoral que se instala durante la gestación, a través de los Ac IgG asimétricos, protegería al embrión/feto del sistema inmune materno posibilitando una… Advisors/Committee Members: Koncurat, Mirta Adriana, Mórtola, Eduardo Carlos, Portiansky, Enrique Leo, Sota, Rodolfo Luzbel de la.

Le choc anaphylactique est une réaction allergique systémique qui survient en quelques minutes et pouvant être fatale. Mon travail de thèse s’articule autour de deux projets dont la finalité est de mieux comprendre le mécanisme physiopathologique. La première partie de ce travail consiste à étudier in vivo chez la souris les contributions des récepteurs Fc aux IgG (FcγRs), des cellules effectrices et des médiateurs contribuant dans un modèle d’anaphylaxie systémique passive induit par une sous-classe particulière d’IgG : des IgG1, des IgG2a ou des IgG2b monoclonales dirigées contre un même antigène. Cette étude a permis de démontrer que le FcγRIII, les neutrophiles et les monocytes/macrophages sont les acteurs majoritaires quelque soit la sous-classe d’IgG de souris ; en revanche, la participation des basophiles ainsi que la contribution relative des médiateurs histamine et PAF sont dépendantes de la sous-classe d’IgG utilisée. La deuxième partie de ce travail consiste à étudier plus particulièrement la population plaquettaire dans un modèle de souris humanisées. Contrairement à la souris, les plaquettes humaines expriment un FcγR, le FcγRIIA déjà identifié comme acteur clé de l’anaphylaxie. Un modèle de choc allergique induit par des IgG humaines dans des souris transgéniques pour le FcγRIIA m’a permis de tester l’hypothèse suivant laquelle les plaquettes participent à l’initiation et/ou à la propagation de la réaction. Ce modèle a permis de mettre en évidence une thrombocytopénie sévère, des complexes plaquettes-leucocytes circulants et de montrer que le transfert de plaquettes ou de leur surnageant restaure les signes cliniques du choc allergique.

Anaphylaxis is a systemic hyperacute allergic reaction that occurs within minutes and can be fatal. The aim of my PhD project is to investigate the physiopathological mechanisms underlying anaphylaxis induction. The first part of my work focused on the contribution of FcγRs, effector cells and mediators in passive murine models of systemic anaphylaxis induced by the different subclasses of mouse specific IgG ; directed against the same antigen: IgG1, IgG2a or IgG2b. This study demonstrated that FcγRIII, neutrophils and monocytes/macrophages are the key players of anaphylaxis induction whatever the mouse IgG subclasses used. On the contrary, basophil participation and the relative contribution of histamine and PAF are IgG subclass dependent. The second part of this work examined the role of platelets in anaphylaxis using a humanized mouse model. Opposing the murine situation, human platelets express an IgG receptor, FcγRIIA. This receptor has already been identified as a key player in anaphylaxis. Using aggregated human IgG to induce anaphylaxis in mice transgenic for FcγRIIA, we tested our hypothesis that platelets contribute to the initiation and/or the propagation of this reaction. Anaphylaxis in this model was accompanied by a severe thrombocytopenia, the presence of circulating platelet-leukocyte complexes and activated platelets. I further demonstrated that the…

▼ A LTA é uma infecção parasitária tendo Leishmania (Viannia) braziliensis) como agente etiológico de maior incidência no Brasil. Em todas as formas clínicas da doença, sabe-se que a resposta imune é dependente de células T. Embora estudos avaliem a resposta humoral na LTA, ainda não está esclarecido o papel de anticorpos específicos na imunidade contra Leishmania. Além disso, o diagnóstico da LTA demonstra dificuldades pois o mesmo é realizado por associações clínicas, epidemiológicas e laboratoriais. Considerando os benefícios da citometria de fluxo, uma nova abordagem utilizada na pesquisa de anticorpos com aplicabilidade superior aos diferentes protocolos de detecção e revelação convencionais, este estudo trouxe uma alternativa através da pesquisa de anticorpos IgG de L(V)braziliensis, aplicável ao diagnóstico da LTA e critério de cura.O objetivo deste estudo foi comparar as técnicas de reação de imunofluorescência indireta (IFI) e citometria de fluxo na avaliação clínica-laboratorial dos pacientes antes e após cura clínica e avaliar a aplicabilidade da citometria de fluxo no monitoramento pós-terapêutico dos pacientes. Soros de 14 pacientes antes do tratamento (AT), 13 pacientes 1 ano após tratamento (PT), 10 pacientes 2 e 5 anos PT foram analisados e os resultados foram expressos em níveis de reatividade de IgG, a partir da porcentagem de parasitos fluorescentes positivos (PPFP). A diluição 1:256 das amostras permitiu diferenciar os indivíduos AT e PT. A análise comparativa da IFI e da citometria de fluxo pela curva ROC (Receiver Operating Characteristic Curve) demonstrou, respectivamente, ASC (área sob a curva) =0,78 (IC95%= 0,64-0,89) e ASC=0,90 (IC95%= 0,75-0.95), demonstrando elevada acurácia do teste de citometria de fluxo. Nossos dados demonstram que 20% foi o melhor ponto de corte identificado pela curva ROC para o ensaio de citometria de fluxo. Este ensaio apresentou sensibilidade de 86% e especificidade de 77%, enquanto a IFI apresentou sensibilidade de 71% e especificidade de 69%. O monitoramento pós terapêutico através da análise comparativa dos índices de desempenho das técnicas em 1, 2 e 5 anos PT, revelou melhor desempenho da citometria de fuxo em relação a IFI. Portanto, a citometria de fluxo demonstrou ser uma alternativa diagnóstica aplicada ao estudo da LTA e que as informações obtidas nesse estudo abrem perspectivas para o monitoramento de cura pós- terapêutica da LTA Advisors/Committee Members: Rêgo Alves Pereira, Valéria (advisor).

▼ Immunoglobulin molecules are extremely effective at providing protection from foreign molecules or viruses; however, in certain cases the naturally occurring immune system cannot provide adequate protection. Monoclonal antibodies are designed to fill these gaps by engineering antigen binding regions capable of targeting and eliminating dangerous molecules. The monoclonal antibodies can function when isolated and able to travel through the blood stream. However, immunoglobulin efficiency decreases upon self-association for two reasons. First, the immune system may recognize the associated molecules and eliminate them depending on the size of the aggregates. Second, if the molecules associate in such a way that the antigen binding regions are no longer accessible they will be unable to function. This thesis discusses molecular simulation techniques that can be used to study the structural changes that occur due to intrinsic molecular flexibility in immunoglobulin molecules as well as the structure of small aggregates that form through self-association. One solvated immunoglobulin molecule was studied by explicitly representing every atom however coarse-graining techniques were required in order to study multiple molecules in the same system. The role of terminal galactose residues in the carbohydrate attached to the Fc domain in an atomisitc model of an antibody molecule was studied in this work. Carbohydrate mobility as well as the protein–carbohydrate hydrogen bonding interactions were compared between simulations with and without terminal galactose residues. It was shown that one of the two biantennary terminal galactose residues preferentially interacts with the protein when both were present; however, when both were removed the carbohydrate structure changed such that new protein–carbohydrate interactions formed. This change in solvent accessible protein surfaces will be an important area of study to both increase effector functions and decrease self-association involving the Fc domain. Understanding through which residues immunoglobulin molecules interact will lead to better designed monoclonal antibodies with increased aggregation resistance. To aid in this understanding, a previously developed residue level coarse-grained model was employed using the same model molecule from the previous atomistic studies. The residues most often involved in self-association of the antibody were individually mutated to alanine and the resulting association frequencies were compared to the “native” immunoglobulin results to determine the residues most important in self-association. Because of the asymmetry in the three-dimensional structure of the model immunoglobulin molecule used in this work, differences in aggregation behavior between two domains with identical amino acid sequence indicated that molecular structure can play a significant role in self-association. These simulation techniques were shown to be effective at studying molecular flexibility and protein–carbohydrate interactions with great chemical detail as well as… Advisors/Committee Members: Coray M Colina, Thesis Advisor/Co-Advisor, Scott A Showalter, Thesis Advisor/Co-Advisor, Ralph H Colby, Thesis Advisor/Co-Advisor.

▼ Neurological complications of HIV disease secondary to opportunistic infections are significantly common. At least one third of patients with advanced HIV disease will present with neurological complications possibly secondary to opportunistic Infections such as Cerebral Toxoplasmosis. In patients with the acquired immunodeficiency syndrome (AIDS), toxoplasmic encephalitis (TE) is usually a presumptive diagnosis based on positive anti-toxoplasma Antibody (Ab), clinical manifestations and characteristic neuroradiological abnormalities. One hundred and nineteen patients were recruited in to this study; all of the participants were sero-positive for HIV, with a history suggestive of opportunistic infections of CNS or obvious neurological symptoms and signs such as headache and confusional state, meningeal irritation, cranial nerve deficits, adult onset seizures and hemiplegia. The aim of the study was to determine seroprevalence of anti-toxoplasma IgG Ab in HIV/AIDS patient with neurological manifestations, and to establish a rational means for the clinician facing decision making concerning empiric anti-toxoplasma therapy. The Study was conducted between November 2008 and January 2009 at the University Teaching Hospital, a major teaching hospital in Lusaka, Zambia, that still offers out-patient as well as inpatient health care to a wide spectrum of population. The study looked at male and female HIV positive adults regardless of whether or not they were on treatment with Highly Active Anti-retroviral therapy (HAART), who presented with central nervous system manifestations/ abnormalities. After obtaining informed consent from the participant or next of kin, history was obtained including demographic factors and anti-retroviral therapy state. Clinical examination was conducted for every participant with special emphasis on neurological examination. Blood samples were collected for serology test for Anti-toxoplasma IgG Ab using TOXO Direct Latex which is rapid slide agglutination procedure, developed for the direct detection of Anti-toxoplasma Ab in human serum. v The seroprevalence of toxoplasmosis was 11.8%, total number of specimen tested were 119 with frequency of 105 negative (88.2%) and 14 positive (11.8%). The majority of the patients were males 61(52.6%), the total number of female participants was 55 (47.4%). Most of the patients 94 (79.0%) were HAART naïve/pre-HAART, and 25 (21.0%) were on HAART. Common clinical manifestations of the patients enrolled were headache, neck-ache/stiffness, confusion, convulsion, fever and focal neurological lesions (hemi-plegia & cranial nerve deficit). Seroprevalence of toxoplasma was quite low as compared to other studies though this could be explained by the small sample size. Further investigations were warranted to determine the diagnostic ability of utilizing the toxoplasma Ab test

▼ Minimal change disease (MCD) and primary (idiopathic) focal segmental glomerulosclerosis (1FSGS), referred to collectively as “primary podocytopathies”, are major causes of nephrotic syndrome in children and adults, and are thought to be due to direct podocyte damage visible only at the electron microscopic level. Lupus podocytopathy (LP) is a newly recognized entity that involves severe podocyte injury in the setting of systemic lupus erythematosus, in the complete absence of peripheral capillary wall immune deposits. All of these pathologic diagnoses hinge on the ultrastructural finding of severe podocyte injury and foot process effacement. In addition to these ultrastructural changes, we have observed the presence of fine granular anti-IgG antibody immunoreactivity on podocyte cell bodies in kidney biopsies of patients with MCD, LP, and some patients with the tip lesion variant and NOS variants of 1FSGS. To validate this finding, we compared antibody staining from primary podocytopathy biopsies with those in biopsies from patients with other disease states, including lesions associated with severe podocyte injury in the absence of immune deposits: secondary (adaptive) focal segmental glomerulosclerosis, thin basement membrane disease, diabetic nephropathy, and renal amyloidosis. We found that a fine granular pattern of anti-IgG immunoreactivity on podocyte cell bodies is a specific morphologic feature of the primary podocytopathies, including virtually all cases of MCD that we encountered, some instances of tip lesion variant and NOS variant of 1FSGS, and one cases of LP. The antigen targeted by the anti-IgG immunostaining in these biopsies exhibited one of several oligoclonal IgG heavy chain subtype plus light chain profiles. Ultra-high resolution microscopy revealed fine linear anti-IgG staining along filtration slit diaphragms, suggesting that IgG deposition may potentially be targeting a filtration slit-associated antigen such as podocin. Our findings suggest the possibility of a direct antibody-mediated mechanism of podocyte injury in the primary podocytopathies, one that potentially targets podocyte-specific protein structures, and which may provide a specific and more rapid diagnostic marker for this group of diseases. The findings also suggest an etiologic relationship between MCD and some instances of 1FSGS. Advisors/Committee Members: Henderson, Joel M. (advisor), Andry, Christopher D. (advisor).

▼ The objective of this study was to determine the effect of meloxicam, administered either in pill form immediately prior to colostrum replacer (CR), or powder form, mixed in solution with CR, on the immunoglobulin G (IgG) uptake, growth, and health of pre-weaned calves. A pilot study considering the potential benefits of meloxicam in pre-weaned heifers indicated administration of the drug following difficult parturition improved body weight (BW) and overall health, but was not associated with passive transfer of immunity (Murray et al., 2015). However, calves from this study were sampled from 10 commercial farms, and therefore, treatment administration was inconsistent, indicated by highly variable passive transfer rates from farm to farm. A total of 30 Holstein dairy calves (16 bulls and 14 heifers) with an average BW of 44.3 kg were housed in a naturally ventilated enclosed calf room and blocked by expected birth date. Calves were removed from the dam within 30 min, prior to suckling, weighed, and randomly assigned to 1 of 3 treatments in a randomized complete block design. Treatments were as follows: (1) CR at 0 hours with no meloxicam (control, CON), (2) 1 mg/kg meloxicam in pill form, before administration of CR (P), or (3) 1 mg/kg meloxicam during administration of CR, crushed and mixed into solution (S). All calves were fed 675 g dry matter (DM) CR for a total fluid volume of just over 3 L, providing a dose of 180 g IgG. Beginning at 24 h of life, calves were offered 432 g DM of milk replacer (MR) (24% CP, 17% fat) daily, split into 2 feedings. Free choice textured starter and water were offered from 24 hours until completion of the study at 42 d. Blood samples were collected at 0 h to analyze initial serum IgG and circulating ketone concentrations, and at 6, 12, 18, and 24 h of life to analyze IgG uptake. Blood samples were collected weekly thereafter for analysis of glucose, plasma urea nitrogen (PUN), and blood ketone concentration. Measurements such as time of consumption for MR, BW, length, hip and withers height, and heart girth were also recorded weekly. There was no effect of meloxicam on skeletal measurements or average daily gain (ADG); however, calves having received meloxicam in pill form before CR administration tended to gain length at a faster rate (cm/d) than those having received colostrum crushed into powder and mixed into solution. There was no significant effect of meloxicam on MR intake, time of consumption for MR, total DMI, or feed efficiency; however, calves having received meloxicam tended to consume a greater amount of starter than those having received the CON treatment. This coincided ketone levels which tended to be greater in blood samples from calves having received meloxicam, compared to those which did not, indicative of greater rumen development.

▼ A large body of data exists demonstrating the key role of FcRn in extending the half-life of therapeutic antibodies by rescuing them from lysosomal degradation. This led to the widely accepted hypothesis that FcRn binding of an IgG via the CH2-CH3 interface of Fc correlates with IgG half-life. Several studies have demonstrated that in vivo half-life can be modified by changing the binding affinity of IgG to FcRn. These modifications were generated by mutating the coding sequence for the Fc region that resulted in enhanced or reduced FcRn binding at endosomal pH without enhancing binding at neutral pH. In contrast to this, we have observed that the half-lifes of IgG molecules that had showed no target-mediated disposition or off-target binding varies widely, even when they share identical Fc domains. This led us to hypothesize that domains of IgG molecules other than Fc could contribute to the modulation of FcRn binding and affect in vivo half-life. This hypothesis was strengthened by recent publications by other groups showing a correlation between antibody charge and the FcRn affinity and/or in vivo half-life. In this study we explored the role of IgG domains other than the FcRn binding domain in altering the affinity between IgG and FcRn and its relation to the in vivo half-life. Here we describe a surface plasmon resonance (SPR) based assay developed to examine the steady-state binding affinity (KD) of IgG molecules to FcRn. We systematically dissected the contributions of IgG variable domain regions in modulating the affinity between FcRn and IgG. Through analysis of a broad collection of therapeutic antibodies containing more than 100 unique IgG molecules against more than 25 different therapeutic targets we have demonstrated that variable domains and in particular CDRs significantly alter binding affinity to FcRn, by 10 to 80-fold, whereas heavy and light chain isotypes do not. Because CDRs modulate the affinity between IgG and FcRn in our in vitro studies, it is important to understand the role they play in modulation of IgG half-life in vivo as this would have far-reaching implications in the half-life optimization efforts of IgG therapeutics.

▼ Immunoglobulin G (IgG) antibodies represent important analytical targets both for their therapeutic properties and for their critical role in the adaptive immune response. While much of the primary structure is conserved across the IgG class, subtle changes in amino acid sequence and the presence or absence of post-translational modifications can have a profound effect on the function and therapeutic potential of a given antibody. As such, there remains a high demand for versatile analytical tools capable of both identification and complete structural characterization of IgGs. The work presented in this dissertation largely focuses on the development of mass spectrometry-based methods for the improved analysis of antibodies. This was accomplished using strategic enzymatic Brodbeltselectivity for regions of particular diagnostic value or to facilitate comprehensive structural characterization. A method based on chromophore-mediated 351 nm UVPD was developed as a means to streamline the identification of antibodies in mixtures by enhancing selectively for the third complementarity determining region of the IgG heavy chain (CDR-H3). The hypervariable sequences within this region serve as the primary determinant of antigen binding specificity and thus provide a molecular signature by which to differentiate unique antibodies. To accomplish this, a highly conserved cysteine residue located in the framework preceding the CDR-H3 region was exploited for selective tagging with an Alexa Fluor 350 (AF350) thiol-selective maleimide. This site-specific tagging combined with strategic enzymatic digestion and 351 nm UVPD allowed selective dissociation of only AF350-labeled peptides for facile discrimination of CDR-H3 sequences within a high-throughput liquid chromatography-tandem mass spectrometry (LC-MS/MS) based workflow. Two variations of middle-down mass spectrometry based on either restricted Lys-C proteolysis or hinge-selective IdeS digestion combined with 193 nm UVPD were used for the characterization of monoclonal antibodies. Both strategies yielded considerably greater diagnostic sequence information when benchmarked against conventional collision- and electron-based activation methods. The Lys-C proteolysis method was found to have considerable implications for the analysis of serological antibody repertoires owing to its facile implementation into high-throughput proteomic workflows and ability to unambiguously differentiate unique CDR-H3 sequences. The development and implementation of a front-end dual spray reactor for high-throughput ion/ion-mediated bioconjugation is demonstrated for the enhanced structural characterization of unmodified and post-translationally modified peptide cations by 193 nm UVPD and CID. The ability to generate ion/ion complexes in real-time followed by efficient covalent conversion allowed integration of the dual spray reactor into a high-throughput LC-MS [superscript n] workflow for rapid derivatization of peptide mixtures.

▼ Bacillus anthracis, the causative agent of anthrax, is surrounded by an antiphagocytic capsule composed of poly-£^-D-glutamic acid (£^DPGA). Antibodies directed against the £^DPGA capsule are opsonic and protective, which makes the capsule an attractive target for vaccine development. However, antibodies of different IgG subclasses differ in their ability to activate effector functions, including activation of complement and phagocytosis. In addition, recent studies found differences in affinity and protective activity between variable region identical IgG subclass switch monoclonal antibodies (mAbs) directed against microbial capsules or outer membrane proteins. We recently generated six mAbs against the £^DPGA capsule and found that only mAbs of IgG3 subclass were protective in a murine model of inhalational anthrax. In order to investigate the role of IgG subclass to protective activity against anthrax, the goal of the study was to generate a full IgG subclass switch family (IgG3 ,,³ IgG1 ,,³ IgG2b ,,³ IgG2a) from two of our £^DPGA mAbs, F26G3 and F24F2, and evaluate these mAbs for their biological and protective activities. Our results showed that only mAbs of IgG3 subclass were protective in vivo, whereas the IgG1, IgG2b, or IgG2a subclass switch mAbs failed to protect. Protective activity of mAbs correlated with high affinity and ability to activate complement and opsonophagocytosis in vitro. These results suggested that the IgG heavy chain constant region (CH) domains contribute to antibody-antigen interaction and ability to protect. To further examine the role of IgG CH domains to antibody function, we generated CH swap mAbs from our protective F26G3 IgG3 and non-protective IgG2b mAbs. Our results suggested a major contribution for the CH2 and CH3 domains of IgG3 for antibody affinity, antibody-antigen interaction and protective activity. Taken together, our results showed that IgG heavy chain contributes to antibody affinity and antibody-antigen interaction, which further affects the protective activity of the anti-£^DPGA mAbs.

▼ Phagocytosis is an evolutionarily conserved mechanism that serves as the first line of host defense in multicellular organisms. Phagocytes are exposed to a variety of ligands on heterogeneous target particles in vivo, and this recognition is driven by an extensive repertoire of receptors with distinct ligand specificity. However, our current view of phagocytosis has been shaped by studying individual receptor-ligand interactions and their downstream signaling pathways. This makes it physiologically relevant to observe the simultaneous engagement of multiple phagocytic receptors and the underlying coordination of downstream signaling pathways for efficient phagocytosis. Potential crosstalk between the two well-characterized opsonic receptors, FcγR and CR3, was briefly explored in the early 1970s, where macrophages were challenged with dual-opsonized target particles. However, subsequent studies on receptor crosstalk have been primarily restricted to the use of single opsonin on different target particles and typically presented at relatively high opsonin concentrations to induce maximal receptor engagement and signaling. Beyond validating these initial explorations on receptor crosstalk, we attempted to identify the early signaling mechanisms that underlie the binding and phagocytosis of dual-opsonized target particles (IgG and IgM/C3bi) during the simultaneous activation of both opsonic receptors, compared to single receptor activation. For this purpose, we used signaling protein inhibitor studies as well as live-cell brightfield and fluorescence imaging to fully understand the role of cytoskeletal elements and tyrosine kinases, F-actin dynamics, internalization kinetics and phagosome maturation rates for FcγRs and CR3. Importantly, opsonic receptors were studied together and in isolation, in the context of relatively low opsonin concentrations on target particles deemed optimal through flow cytometry analysis and particle binding assays. We saw enhanced particle binding and a synergistic effect on particle internalization when FcγRs and CR3 were simultaneously engaged with relatively low opsonin concentrations on target particles. Next, we investigated the early signaling requirements for the binding and uptake of single and dual-opsonized particles. Inhibition of early signaling and cytoskeletal molecules revealed a differential involvement of Src kinase for FcγRs- versus CR3- and dual receptor-mediated phagocytosis. Src activity recruits Syk kinase, and we observed intermediate levels of Syk phosphorylation in dual-opsonized particles compared to those opsonized with IgG or IgM/C3bi alone. These results likely correlate to the intermediate levels of F-actin that is recruited to sites of dual-opsonized particle uptake and underlie the notoriously delayed internalization of IgM/C3bi-opsonized target particles by macrophages.

A disponibilidade de hemoderivados é um parâmetro importante para medir a qualidade da saúde em um país. Dentre os produtos hemoderivados, imunoglobulinas tem alto valor agregado. O Instituto Butantan tem por objetivo o estabelecimento de uma planta industrial para fracionamento de plasma, com um processo produtivo baseado principalmente em cromatografias. Eventos tromboembólicos a partir de infusões de imunoglobulinas por via intravenosa (IgIV) foram relacionados com presença de Fator XI de coagulação (FXI) como contaminantes nas preparações de IgIVs. Com objetivo de detectar o FXI nas frações, o processo cromatográfico foi testado em escala piloto, bancada, e em cromatografia direta e o FXI foi dosado nas frações iniciais e no produto final IgIV. Foram estabelecidos os métodos de dosagem de atividade de FXI por tempo de coagulação e ensaio cromogênico. Concluímos que o FXI acompanha a IgG nas etapas iniciais dos processos cromatográficos e verificamos que ocorre a presença de FXI nos produtos finais. Este trabalho contribui para o desenvolvimento do conjunto de testes de controle de qualidade de biofármacos derivados de plasma humano.

The availability of hemoderivatives is an important parameter to measure a countrys health quality. Among hemoderivatives products, immunoglobulin have high value.. Instituto Butantan, aims the establishment of an industrial plant for plasma fractionation with a process drawn, based mainly in chromatographies. Thromboembolic events from infusions of intravenous immunoglobulins (IVIg) have been related with the presence of coagulation Factor XI (FXI) as contaminant in the IVIG preparations. With an objective of tracking FXI in the chromatographic fractions, the process was tested in pilot and bench scales and in direct chromatography and the FXI was measured in the initial fractions and in the final product IVIg. The methods of measurement of FXI activity thru coagulation time and chromogenic assay were established. We have concluded that FXI accompanies IgG in the early stages of the chromatographic processes and verified that the presence occurs in the final products, This work contributes to the development of the set of quality control tests of biopharmaceuticals derivatives from human plasma.

▼ In Ethiopia, the general population is quite vulnerable to unpredictable cyclic epidemics of Plasmodium falciparum malaria. However, there is very little information on the anti-malaria immune profile of the population residing in the endemic regions of the country. This study was designed to investigate the nature of humoral immune response to malaria in two population groups in two endemic localities, Shewa Robit in the north and Boditi in south. In a cross-sectional study, the study participants were diagnosed for malaria infection microscopically and by the rapid diagnostic test (RDT). The sera were tested by using enzyme-linked immunosorbent assay (ELISA) for total immunoglobulin (Ig) G against P. falciparum blood-stage vaccine candidate antigens: apical membrane antigen 1 (AMA1), glutamate-rich protein (GLURP) R2 region, and merozoite surface protein 2 (MSP2) allelic variants (3D7 and FC27) in Shewa Robit. Total IgG against GLURP-R0, MSP3 and GMZ2 and IgG subclasses against GLURP-R0 and MSP3 were assayed in both Shewa Robit and Boditi sera. Whereas 23(8.6%) blood-smear-positive cases for P. falciparum were detected in Boditi, all Shewa Robit study participants had no detectable P. falciparum infection. At both localities total IgG prevalence and levels to GMZ2 were significantly higher than the response to the component domains iv (GLURP-R0 and MSP3) indicating the induction of strong GMZ2-specific natural antibodies. There was significant difference between the median antibody level to GMZ2, GLURP-R0 and MSP3 compared to the responses to other antigens tested in Shewa Robit, indicating that GMZ2 could be a more relevant blood-stage malaria vaccine candidate antigen. Higher total IgG and subclass prevalence and levels were detected in Shewa Robit than Boditi, suggesting difference in the intensity of malaria transmission in the two localities and/or genetic differences between the two population groups in their response to blood-stage P. falciparum antigens. In both study sites, IgG subclass antibody levels to GLURP-R0 were significantly higher than that to MSP3 for all corresponding subclasses in most individuals, indicating the higher relative immunogenicity and protective potential of GLURP-R0 compared to MSP3. Against both GLURP-R0 and MSP3, the ratio of cytophilic to noncytophilic antibodies was >1 in the majority of the study participants, in both study sites, indicating the induction of protective antibodies against the two antigens. Analysis of age-related pattern in antibody levels against the antigens tested showed a positive association with increasing age for most antigens suggesting the role of intrinsic agerelated factors in immune maturation. The age factor appears plausible as there was no evidence for increase in antibody response with increasing frequency of reported past clinical malaria. Overall, the study has shown that Ethiopian population groups residing in unstable and seasonal malaria epidemiological settings have a high prevalence and levels of long-lived antibodies that readily… Advisors/Committee Members: Prof. Beyene Petros (advisor).

▼ Antibodies are the defining characteristic of the humoral immune response. Their functions are diverse, including direct neutralization of pathogens and recruitment of other immune molecules or cells. While most successful vaccines induce protective neutralizing antibody responses, effective vaccine-elicited neutralizing antibodies against some pathogens, including HIV, HCV, malaria, and TB, remain elusive. Thus, researchers have begun to focus on how vaccines can elicit strong non-neutralizing antibody functions, including recruitment of innate immune factors for antibody-dependent cellular cytotoxicity, complement deposition, and anti\-body-dependent phagocytosis. The antibody's constant region (Fc) mediates most effector functions through isotype and subclass selection or alteration of the structure of the Fc-attached N-glycan, which controls function with exquisite specificity. Glycan modifications are naturally induced during inflammatory conditions such as autoimmune disease and natural infection however, the specific signals that regulate Fc-glycosylation remain unknown. This dissertation sought to understand how antibody glycosylation is regulated and how it can be programmed through vaccination. To do this, we first developed a technique to analyze antibody glycan structures both of bulk Fc and antigen-specific antibodies. Using this technique, we observed significant modulation of antibody glycans during viral infection as well as in vaccine-elicited antibodies. To identify specific signals important for altering the antibody glycan, we transcriptionally profiled stimulated B cells and identified a set of innate and adaptive stimuli that regulate the genes responsible for antibody glycosylation. The results described in this dissertation begin to define the specific mechanism(s) by which infection and vaccination modulate antibody glycosylation to elicit functional antibodies that can ultimately provide effective and sustained protection from infection.

▼ Predominant antibody deficiencies are the most frequent primary immunodeficiencies (PID) in adults. This is a very heterogeneous group of immunodeficiencies, that include patients with a large clinical spectrum with no correlation with immunoglobulin concentrations. Since the 1990s different diagnostic criteria and classifications for PID have been proposed. PID is a pathology poorly known by most physicians. This, and the great clinical variability of the manifestations, lead both to a lack and to a delay in the diagnosis of PID. For a correct diagnosis of common variable immunodeficiency (CVI), deficiency of IgG subclasses and IgA deficiency, it is essential to perform a functional study in order to evaluate the specific antibody response to polysaccharide antigens. Lung disease in adult patients with PID is the leading cause of morbidity and mortality with an important deterioration of their quality of life. In the present study we described a cohort of 85 adult patients with PID monitored by the Infectious Diseases Unit of Germans Trias i Pujol Hospital. Most patients belong to the group of isotope or light chain deficiencies with generally normal numbers of B cells. They are diagnosed in the fifth decade of their life, with a slight predominance of women. Approximately one-third of the patients present chronic lung disease and bronchiectasis when diagnosed with PID; more than a third of the patients present a poor response to the vaccines and a quarter of the patients require replacement therapy with immunoglobulins. Clinical, radiological and laboratory characteristics of patients diagnosed with hypogammaglobulinemia of uncertain significance (HGUS) have been compared with those diagnosed with probable or possible CVI - according to the 2013 Ameratunga criteria -, and no differences between the two groups were found. Although patients with HGUS had a conservative management, they did not present a worse prognosis. We also compared clinical, analytical and radiological characteristics of patients with PID, dividing those who were diagnosed before 2009, and those who were diagnosed after. From 2009 to present, we have performed different interventions in order to improve the awareness of these diseases among physicians of our area. We observed an increase in the PID diagnosis and a tendency to reduce the diagnosis delay. No differences were found in clinical, analytical and radiological characteristics of patients in the two groups. We also compared patients with or without bronchiectasis, being pneumonia the only predictor factor of bronchiectasis. In addition, we observed a trend towards lower concentrations of IgG2 and IgG3 in patients with bronchiectasis. Finally, the functional response was evaluated, we assessed the specific Salmonella typhi antibodies, we measured pre and post vaccination concentrations in adult patients with PID. None of the patients on substitute treatment responded to the vaccine. Patients without treatment and with clinically stability responded more frequently than those symptomatic.… Advisors/Committee Members: [email protected] (authoremail), true (authoremailshow), Pedro-Botet Montoya, Ma Luisa (director), true (authorsendemail).

▼ A leishmaniose tegumentar americana (LTA) é um problema de saúde pública, que afeta a produtividade e a vitalidade das pessoas. Embora estudos avaliem a resposta humoral na LTA, ainda não está completamente esclarecido o papel de anticorpos específicos na imunidade contra Leishmania. Além dos desafios sócio-econômicos que agravam ainda mais o problema da LTA, o diagnóstico da doença demonstra dificuldades, sendo freqüentemente necessário à correlação de vários elementos para se chegar ao diagnóstico definitivo. Dessa maneira, o objetivo desse estudo, foi avaliar o uso da citometria de fluxo, como uma metodologia alternativa na avaliação diagnóstica em indivíduos com LTA ativa (AT), como critério de cura pós-terapêutica em indivíduos após o tratamento (PT), naqueles com cura clínica espontânea (CE) e em indivíduos com outras doenças (doença de Chagas – DC, leishmaniose visceral–LV, hanseníase e esporotricose). A reatividade relatada pela citometria de fluxo, utilizando promastigotas vivas e fixadas de Leishmania (Viannia) braziliensis foi respectivamente, 86% e 90% de porcentagem de parasitas fluorescentes positivos (PPFP). Por análise comparativa, entre citometria de fluxo e imunofluorescência indireta, utilizando os pacientes AT, 1, 2 e 5 anos PT, verificou-se que a citometria de fluxo mostrou sensibilidade de 86% e especificidade de 77%, enquanto a IFI teve uma sensibilidade de 78% e especificidade de 85%. Contudo esta técnica teve confirmada a sua aplicabilidade no critério de cura da LTA. Analisando os resultados apresentados pelos pacientes CE, obtivemos um desempenho com 100% de especificidade. O diagnóstico diferencial da LTA que utiliza soros de pacientes DC e LV demonstrou reação cruzada, revelando resultados falso-positivos. No entanto, a utilização de soros de pacientes com esporotricose, tuberculose e hanseníase, demonstrou potencial para o uso da citometria de fluxo no diagnóstico diferencial. O estudo mostrou que os ensaios realizados utilizando anticorpos IgG, detectados por Leishmania (V.) braziliensis na citometria de fluxo, representam uma ferramenta alternativa para o diagnóstico da LTA e também abrem perspectivas para a utilização no monitoramento e critério de cura da LTA.

As espécies Klebsiella pneumoniae, Escherichia coli e Pseudomonas aeruginosa são responsáveis por infecções neonatais hospitalares. Lipopolissacarídeo (LPS) é o principal indutor de respostas inflamatórias. Os objetivos foram avaliar a transferência placentária de IgG reativa ao LPS de K. pneumoniae, E. coli O111, O26 e O6 e P. aeruginosa empregando ELISA para dosar IgG em soro materno e de cordão de 29 neonatos pré-termos e 32 a termo; analisar IgM total e específica no soro materno; e investigar a influência das patologias apresentadas pelas mães na transferência placentária. Concentrações de IgG total foram reduzidas em pré-termos como esperado, porem índices de transferência placentária de IgG total e IgG anti-LPS foram sistematicamente reduzidos quando comparados aos neonatos a termo. Níveis de IgM total e anti-LPS foram equivalentes em mães de ambos os grupos. As patologias das mães influenciaram os níveis de IgM no grupo de mães de pré-termos. Estes resultados indicam uma imunidade adquirida deficiente pelo grupo pré-termo aumentando os riscos de infecção.

Klebsiella pneumoniae, Escherichia coli and Pseudomonas aeruginosa species are responsible for neonatal nosocomial infections. Bacterial lipopolysaccharide (LPS) is the major inducer of the inflammatory responses. The aims were to evaluate the placental transfer of IgG reactive to LPS present in K. pneumoniae, in E. coli O111, O26 and O6 and in P. aeruginosa employing ELISA to detect IgG in maternal and cord sera from 29 preterm and 32 term neonates; to analyze total and specific IgM on the mothers sera; and to investigate the influence of the pathologies presented by some mothers in the placental transfer. Total IgG concentrations were reduced in preterm neonates as expected, but placental transfer indexes of total and anti-LPS IgG were systematically reduced when compared with term neonates. Total and anti-LPS IgM levels were equivalent on mothers of both groups. The mothers pathologies influenced only the IgM levels in the preterm mothers group. These results indicate a deficient acquired immunity by the preterm group increasing the risk of infection.

A importância em conhecer o padrão alimentar em mosquitos da Família Culicidae permite esclarecer alguns aspectos relacionados à transmissão de zoonoses e estimar o grau de contato humano-vetor que é fator relevante em estudos epidemiológicos. Com o objetivo de explorar o comportamento alimentar dessa Família, em área epizoótica de febre amarela silvestre, foram coletados exemplares nos municípios de Santo Antônio das Missões e Garruchos, Estado do Rio Grande do Sul. Fêmeas ingurgitadas foram obtidas por aspiração em ambiente de mata, no período de setembro de 2005 a abril de 2007 e identificadas segundo fonte de sangue ingerido através da técnica imunoenzimática ELISA de captura no sistema avidinabiotina. Foram testadas seis fontes de alimento: ave, bovino, eqüino, humano, macaco e rato. Os resultados obtidos mediante a padronização de anticorpos monoclonais possibilitaram demonstrar pela primeira vez o reconhecimento de sangue humano ingerido nesses mosquitos pelo emprego da subclasse IgG1 e comprovar a sensibilidade e especificidade da técnica ELISA de captura. No município de Santo Antônio das Missões, de um total de 190 amostras, 60,9% reagiram para sangue de boi, 23,6% para humano, 9,9% para ave, 1,9% para macaco e 3,7% para combinações de dois hospedeiros. Quanto às amostras referentes ao município de Garruchos, das 158 fêmeas capturadas na área Cachoeirinha pode-se observar reatividade para ave (16%), boi (29,6%), humano (36,8%), cavalo (4%), macaco (0,8%) e combinações de hospedeiros (12,8%), enquanto que para as 149 fêmeas pertencentes à área de São José, detectou-se sangue ingerido de boi em (51,5%), ave e humano (11,5%), macaco (6,2%), cavalo (0,8%) e mistos (18,5%). Aedes scapularis, Aedes crinifer, Culex (Culex) spp., Haemagogus leucocelaenus apresentaram maior número de fêmeas ingurgitadas nos dois municípios. Os resultados obtidos com Aedes scapularis sugerem ecletismo, conforme combinações detectadas em amostras de sangue de diferentes fontes. Haemagogus leucocelaenus apresentou a maior proporção de amostras contendo sangue humano em relação às demais fontes e essa característica traz implicações, por ser espécie incriminada na transmissão e por se tratar de área de ocorrência de epizootias de febre amarela.

The knowledge of mosquitoes Culicidae host feeding patterns permits to clarify some aspects related to zoonosis transmission and to estimate the degree of human-vector contact which is relevant in epidemiological studies. Aiming to explore the feeding behavior of these mosquitoes, specimens were collected in the municipalities of Santo Antônio das Missões and Garruchos, Rio Grande do Sul, an epizootic area of sylvatic yellow fever. Engorged females were collected by aspiration from forested areas from September 2005-April 2007 and their blood meals were identified using the avidin-biotin system of immunoenzymatic ELISA capture. Six blood meal sources were tested: bird, cattle, horse, human, monkey and rat. The result achieved with the species-specific IgG1 mAb was unprecedented for mosquito…

A toxoplasmose afeta cerca de um bilhão de pessoa em todo mundo, é geralmente assintomática, apesar de doença ocular ou doenças grave e letal em fetos, pacientes com HIV e transplantados. A sorologia é a principal ferramenta para o diagnóstico e determinação de incidência, que é uma tarefa difícil, devido à alta prevalência na maioria dos países. Estudos de incidência são ideais em crianças, mas este grupo é protegido pela sociedade e de difícil abordagem por métodos invasivos como a punção venosa. A saliva pode ser uma ótima alternativa por sua coleta não ser invasiva, aceitável para crianças, e conter pequenas quantidades de IgG, eliminada através da mucosa gengival e fluido crevicular. Métodos de detcção de anticorpos disponíveis no mercado estão focados em amostras de soro, com baixa sensibilidade e são raros os relatos de pesquisas com material biológico alternativo, como a saliva. Sendo assim, padronizamos imunoensaios com alta sensibilidade para detecção de anticorpos anti- T. gondii na saliva frente a amostras de soro de 20 voluntários adultos. A sensibilidade e especificidade dos nossos dot-ELISA e ELISA de captura com proteína A foram semelhantes entre soro e saliva. Também testamos 100 amostras de saliva de universitários em nossos ensaios, onde mostramos uma frequência da toxoplasmose de 19% (IC 95% 12-28%). Imunoensaios para detecção de IgG anti-T. gondii em saliva são uma ferramenta muito promissora para estudos epidemiológicos da toxoplasmose em crianças ou outros grupos protegidos.

Toxoplasmosis that affects about one billion people worldwide is usually asymptomatic, despite ocular disease and severe and lethal disease in fetuses, AIDS patients and transplant recipients. Serology is the main approach for diagnosis and incidence determination is a difficult task due to high prevalence in most countries. Incidence studies are feasible in children but this age group is protected and difficult to approach by invasive methods as venipuncture. Saliva could be obtained by non-invasive procedure, acceptable for children, and it contains small amounts of IgG from mucosal and gingival crevicular fluid. Available antibody detection methods are focused in serum samples, with low sensitivity and few reports of alternative biological material, like saliva. Here, we standardized immunoassays with high sensitivity for detection of anti-T. gondii IgG in paired saliva and serum sample from 20 adult volunteers, which allows DOT-ELISA and a Protein A IgG capture assay. The sensitivity and specificity of the saliva DOT-ELISA were similar to sera ELISA. We also tested 100 saliva samples from university graduates in all assays, showing 19% (95%CI 12-28%) frequency of toxoplasmosis in this group, lower than reported for our area. Protein A IgG capture saliva assay was also efficient with similar results. Immunoassay with saliva IgG for toxoplasmosis is a very promising tool for use for the epidemiology of toxoplasmosis in children or other protected groups.

Passive immunity acquired by the newborn foal through the colostrum is essential to prevent perinatal infections. The aim of this study was to establish the sensitivity and specificity of the zinc sulfate turbidity test (ZST) 12 hours after first suckling for the detection of immunoglobulins (IgG) to indicate or not the failure of passive immunity transfer. There was no difference in the ZST results obtained from blood collected at 12 (n=110) and 18 (n=38) hours, confirming that the test may be performed as early as 12 hours after the first colostrum intake. When compared to the single radial immunodiffusion test, the ZST test showed 76.50%, 95.65% and 94.68% sensitivity and 93.75%, 93.94% and 75.92% specificity, respectively, for a standard of 400, 600 and 800 mg dL-1 of immunoglobulins (IgG). The results of the ZST test, i.e. according to label instructions, performed 12 hours after the first suckling at 37 °C is a reliable diagnostic tool for detecting IgG levels in newborn foals.

A imunidade passiva adquirida pelo potro neonato através da ingestão do colostro é essencial para a prevenção das infecções neonatais. O objetivo deste trabalho foi determinar a sensibilidade e a especificidade do teste da turvação pelo sulfato de zinco (TSZ) 12 horas após a primeira ingestão de colostro para detecção de imunoglobulinas G (IgG) para indicar ou não a deficiência de transferência da imunidade passiva. Não houve diferença nos resultados do teste TSZ com amostras séricas de potros PSC coletadas 12 (n=110) ou 18h (n=38) após a primeira ingestão do colostro, confirmando que o teste pode ser conduzido 12h após a ingestão de colostro. Quando comparado com a imunodifusão radial simples, o teste TSZ apresentou sensibilidade de 76,50%, 95,65% e de 94,68% e especificidade 93,75%, 93,94% e de 75,92%, para padrões de 400, 600 e 800mg dL-1 de IgG, respectivamente. Assim, o TSZ é um valioso teste para o diagnóstico no campo, desde que sejam seguidas estritamente as indicações do fabricante, especialmente quanto à temperatura. O teste pode e deve ser realizado 12 horas após a primeira mamada, pois apresenta bom índice de precisão.

Neuromyelitis optica (NMO) ist eine gegen Astrozyten gerichtete Autoimmunerkrankung des zentralen Nervensystems, die vor allem den optischen Nerv und das Rückenmark betrifft und zu Lähmungen und eingeschränkter Sehkraft führt. Die Krankheit ist gekennzeichnet durch spezifische Autoantikörper, die sich gegen konformationelle Epitope auf den extrazellulären Schleifen des astrozytären Wasserkanals Aquaporin 4 (AQP4) richten. Die vorliegende Arbeit behandelt die Identifizierung von Epitop-Imitatoren für diese AQP4- spezifischen Antikörper (NMO-IgG). Hierfür wurde eine Phagen-präsentierte 12-Mer-Peptid- Bibliothek für ein Biopanning mit aufgereinigten polyklonalen Immunglobulinen eines NMOIgG- seropositiven Patienten verwendet. Nach einer Spezifitätszunahme in drei Biopanning- Runden wurden einzelne Phagen-Klone isoliert und ihre Reaktivität mit NMO-IgG in ELISAVersuchen evaluiert. Weiters wurden die Peptide, die durch DNA-Sequenzierung der einzelnen Phagen-Klone ermittelt wurden, mit Hilfe Mimotop-basierter Computerprogramme auf humanes AQP4 abgebildet. Basierend auf den ELISA-Ergebnissen und der errechneten Lage der Mimotope wurden acht vielversprechende Kandidaten ausgewählt und in einer FACS-basierten Analyse auf ihr Potential, die Bindung von NMO-IgG an sein Antigen, AQP4, zu blockieren, untersucht. Die FACS-Experimente ergaben, dass vier Peptide dazu fähig sind, die Interaktion von NMO-IgG mit AQP4 zu reduzieren, was darauf hindeutet, dass diese Peptide in der Tat Epitope von NMO-IgG imitieren. Aufgrund seines polyklonalen Ursprungs enthält der in dieser Arbeit verwendete Antikörper-Pool nicht nur eine, sondern mehrere Subpopulationen von NMO-IgG. Hier wurden Mimotope für mindestens zwei Untergruppen von NMO-IgG gefunden: eine A-Schleifen-unabhängige und eine A-Schleifenabhängige. Die Identifizierung der vier Mimotope stellt eine solide Grundlage dar, von der ausgehend langfristig einige Anwendungen vorstellbar sind. Die Mimotope könnten die Klassifizierung der Antikörper-Pools verschiedener Patienten nach ihrer Reaktivität mit unterschiedlichen Mimotopen ermöglichen, oder für aktive Immunisierungsstrategien verwendet werden, z. B. um im Tiermodell den Effekt bestimmter NMO-IgG-Subpopulationen zu untersuchen.

Neuromyelitis optica (NMO) is a severe autoimmune astrocytopathy of the central nervous system (CNS) that preferentially affects the optic nerve and the spinal cord leading to paralysis and impaired vision. The disease is hallmarked by specific autoantibodies that target conformational epitopes composed of the extracellular loops of the astrocytic water channel aquaporin 4 (AQP4). This study addresses the identification of epitope mimics (so-called mimotopes) for these AQP4-specific autoantibodies (NMO-IgG) For this purpose, we used a random phagedisplayed 12-mer peptide library for biopanning with purified polyclonal immunoglobulin G (IgG) of an NMO-IgG-seropositive patient as target. After increasing target specificity within three rounds of panning, single phage clones…
