▼ PDZ molecular scaffolding proteins have been most
studied in neurons, but are
present in other cells. PDZ proteins
typically bind membrane proteins to regulate receptor
surface
expression and to support junctional complexes. GRIP1 is a 7-PDZ
domain
scaffolding protein that has roles in neurons to facilitate
glutamate receptor trafficking.
However, GRIP1 has very different
functions in other tissues. GRIP1 is needed to form a
junctional
barrier between the skin dermis and epidermis. We have found that
GRIP1 is
expressed in platelets and T cells and that GRIP1 has a
functional role in each cell type
independent of glutamate
receptor signaling. We hypothesized that platelet GRIP1
regulates
platelet function and thrombus formation and that T cell GRIP1
regulates T cell
activation as evidenced by in vitro studies and
using a cardiac transplant model.
Platelet-specific GRIP1-/- mice
were found to have decreased hemostasis and
delayed thrombosis in
vivo, but no change in agonist-induced activation in vitro. Using
mass spectrometry analysis of proteins that immunoprecipitated with
GRIP1, we
identified GRIP1 interactions with the GPIb-IX complex.
The GPIb-IX complex is
necessary for platelet adhesion. We
confirmed that GPIb-IX complex protein interactions
are different
in WT and GRIP1-/- platelets and may cause the in vivo defects.
We
also investigated GRIP1 function in T cells. WT and T cell-specific
GRIP1-/-
mice received MHC mismatched cardiac allografts and T
cell GRIP1-/- mice had
prolonged transplant survival in multiple
rejection models. GRIP1-/- T cells had inhibited
proliferation and
activation following in vitro stimulation. We found that GRIP1-/- T
cells
had increased surface expression of the strong inhibitory
receptor CTLA-4. Blocking
CTLA-4 in GRIP1-/- mice rescued
transplant rejection.
Overall, we have found that GRIP1, a
molecular scaffolding protein, has
important cell regulatory
effects in platelets and T cells that markedly differ in various
cell types. We have revealed important functions for GRIP1 in
mediating platelet
thrombosis and in T cell-mediated transplant
rejection.

▼ Malignant melanoma is a growing problem with more and more people in Sweden and the world suffering from this cancer. Malignant melanoma is a disease that when discovered in time can be treated successfully with surgical methods, but the real challenge lies in treating the disease after its spread. Treatment in the past for advanced malignant melanoma has been unsuccessful with no positive effect on overall survival. However, in the last couple of years, new treatment has arrived with focus on priming the immune system to eradicate the tumors. One new drug is the CTLA-4 inhibitor ipilimumab that is given as intravenous infusion. CTLA-4 is a protein located on regulatory T-cells and that is upregulated on activated cytotoxic T-cells. This protein mediates an inhibitory signal that attenuates T-cell-activation. Treatment with the CTLA-4 inhibitor has been shown to increase overall survival. However, not much is known about how well ipilimumab synergizes with other drugs used for treatment of malignant melanoma. This is a literature study with the aim to evaluate if ipilimumab is used best as monotherapy or if it is of better use as part of a combination therapy. Search was made in PubMed with the key-words "Ipilimumab", "Ipilimumab treatment", CTLA-4 inhibitor" and "treatment malignant melanoma”. Six articles were chosen and each of these analyzed the effect of ipilimumab alone or combined with other agents against malignant melanoma. The combination of ipilimumab and the alkylating agent dacarbazine was shown to have a better impact on overall survival compared with monotherapy with dacarbazine, but this combination also showed an increase in serious adverse events. Ipilimumab also showed to work in synergy with both the PD-1-inhibitor nivolumab and the granulocyte macrophage colony-stimulating factor (GM-CSF) sargramostim. Combination with sargramostim was also shown to decrease the amount of serious adverse events. Combination with a gp100 peptide vaccine failed to show any positive effects on overall survival. Also prophylactic treatment with budesonide showed no further gain in overall survival. The effect of ipilimumab was found to have a dose-ranging effect, with higher dose treatment having a better effect but also with more serious adverse events. The results of this literature study showed that ipilimumab has a better effect with higher dose and that it can work in synergy with other agents such as nivolumab and sargramostim. Results also showed that occurring adverse effects during treatment with ipilimumab may be treated with systemic glucocorticoids that did not affect the tumor-killing ability of ipilimumab. These results should be evaluated in bigger studies and with longer follow up time.

▼ The differentiation of multipotent naïve T cells is influenced by the microenvironment. Cytokines, costimulatory proteins and other biological factors can tune this differentiation process, influencing cell fate. Controlling naïve T cell differentiation can guide the type of immune response elicited since each T cell subset has a specific function in the immune system. In this dissertation, I examine the participation of costimulatory molecules expressed on the surface of naïve CD4+ T cells in differentiation of these cells. I demonstrate that stimulation through the TCR and
CTLA-
4 directs naïve CD4+ T cell differentiation to regulatory T cells in the absence of exogenous cytokines. I evaluate how combined stimuli influence differentiation and function in T cells. Combined stimulation through
CTLA-
4 and CD28 (CD3+CD28+
CTLA-
4) results in distinct functional outcomes from combined stimulation through
CTLA-
4 and ICAM-1 (CD3+ICAM-1+
CTLA-
4) or alternatively, ICAM-1 and CD28 (CD3+CD28+ICAM-1). Differentiation to Th1, Th2 or Treg cells has been evaluated in our previous studies. In this dissertation, I extend these studies by examining whether costimulation in the absence of exogenous cytokines can support Th17 differentiation. I found that costimulation through ICAM-1, CD28, LFA-1, or
CTLA-
4 did not activate naïve CD4+ T cells to differentiate to Th17 cells. I also evaluated how the low affinity IgE receptor, CD23, expressed on T cells participates in naïve T cell differentiation and mature T cell function. CD23 functions as a negative regulator of Th2 responses by inhibiting differentiation of naïve T cells to Th2 cells and enhancing activation of Th1 cells in mature T cells. Next, I examined how lipoproteins relevant to atherosclerosis may guide differentiation of naïve CD4+ T cells. Consistent with their known roles in promoting or inhibiting atherosclerosis, oxLDL activates differentiation to Th1 cells whereas HDL inhibits T cell proliferation and viability. Different responses by naïve T cells to these lipoproteins may have direct implications in how atherosclerosis is exacerbated or attenuated during disease. Finally, I explore whether autoimmunity is involved in a mouse model of emphysema. I demonstrate that T cells adoptively transferred emphysema to naïve, immunodeficient mice, supporting a role for autoimmunity in an elastase-induced model. Peptide therapy targeting the interactions between ICAM-1 and LFA-1 was able to reduce severity of emphysema as well.

▼ Au cours des dernières années, l’immunothérapie a révolutionné le paysage en oncologie. L’anti-CTLA-4 a montré son efficacité sur la survie globale des patients atteints de mélanome métastatique. Cependant, ce traitement présente des limites à son utilisation telles que l'efficacité clinique obtenu chez seulement 20% des patients et la survenue fréquente de colites pouvant être sévères. La recherche de biomarqueurs prédictifs de réponse clinique et/ou de développement de toxicité devient maintenant un enjeu majeur pour sélectionner les patients pouvant avoir un bénéfice à l’utilisation de ces traitements. En partant de l’observation que les colites induites par l’anti-CTLA-4 présentent des similitudes avec les maladies inflammatoires chroniques de l'intestin, nous avons émis l’hypothèse de l’existence d’un microbiote intestinal associé à une dysrégulation du système immunitaire pouvant prédire la réponse clinique et/ou la survenue d’une colite induite par l’anti-CTLA-4. Nous avons montré dans une cohorte de patients atteints de mélanome métastatique et traités par ipilimumab, qu'un microbiote intestinal enrichi en Faecalibacterium et autres Firmicutes est associé à une meilleure survie globale et sans progression ainsi qu'un risque accru de développer une colite. Les patients avec une flore enrichie en Firmicutes présentent également après traitement par ipilimumab, une activation lymphocytaire plus efficace. Par la suite, nous nous sommes intéressés aux métabolites issus du microbiote fécal et leur implication dans la réponse à l'anti-CTLA-4. Le butyrate est le principal métabolite produit par les Firmicutes. Nous avons observé chez la souris, une inhibition de l'efficacité anti-tumorale de l'anti-CTLA-4 lorsqu'elles étaient supplémentées en butyrate. In vivo, nous avons montré que le butyrate inhibe la surexpression sur les cellules dendritiques, des molécules CD80 et CD86 (molécules B7) induite par l'anti-CTLA-4. Cette immaturité des cellules dendritiques entraine un défaut d'activation des lymphocytes T spécifiques d'antigènes dépendant de l'axe CD28/B7 réduisant ainsi l'efficacité anti-tumorale. Chez l'Homme, nous avons valider cette hypothèse en montrant qu'une concentration sérique élevée en butyrate est associée à une diminution de la survie globale et sans progression comparativement aux patients avec un faible niveau de butyrate sérique.Ces travaux mettent en évidence le lien entre la composition du microbiote et les réponses immunologiques au blocage du CTLA-4. Ils apportent une explication sur un lien indirect via le butyrate entre la composition du microbiote intestinal et la réponse anti-tumorale aux immunothérapies.

▼ We have previously shown that wild type (wt) mice exhibit susceptibility to immunization with human (h) thyrotropin receptor (TSHR), but resistance to mouse (m) TSHR, while TSHR knockout (KO) mice are susceptible to mTSHR, indicating the existence of robust immune tolerance against the mTSHR in wt mice. This tolerance may be mediated by either centrally or peripherally. We here explored the contribution of a peripheral arm of immune tolerance against the mTSHR by using antibodies to deplete regulatory T cells (Tregs), to antagonize co-inhibitory molecules and/or to stimulate co-stimulatory molecules. Antagonistic anti-co-inhibitory molecules, cytotoxic T lymphocyte antigen 4 (CTLA4) and programmed cell death 1 ligand 1 (PDL1), induced only low levels of anti-TSHR antibodies without induction of hyperthyroidism in a mouse Graves'model. In this experimental setting, antibody levels were significantly higher in THSR+/- mice than wt mice. However, agonistic anti-co-stimulatory molecules, CD40 and CD137, and Treg-depleting anti-CD25 antibodies showed no effect. All these data suggest that peripheral immune tolerance against the mTSHR may play a minor role, and imply the importance of central tolerance, in immune tolerance against mTSHR in mice. Additional studies on central tolerance to the mTSHR will be necessary for completely delineating the mechanisms for immune tolerance against mTSHR in mice.

▼ A proteína CTLA-4 é expressa principalmente em células T ativadas, possuindo um papel fundamental na resposta imune, exercendo efeito regulador na ativação de célula T através da sua ligação com as moléculas da família B7, as quais são expressas em células apresentadoras de antígenos. Polimorfismos do gene CTLA-4 têm sido associados a várias doenças autoimunes e, recentemente, à doenças neoplásicas e infecciosas. A paracoccidioidomicose é uma micose sistêmica, causada pelo fungo dimórfico Paracoccidioides brasiliensis. As manifestações clínicas desta doença estão associadas a vários fatores como a secreção alterada de citocinas, hipergamaglobulinemia, e depressão da imunidade celular, sendo que a hiporesponsividade é também atribuída a uma maior expressão de CTLA-4 em células T de pacientes quando comparados a indivíduos controles. O presente trabalho teve por objetivo estudar a possível associação dos SNPs -318C/T na região promotora e +49A/G do éxon 1 do gene CTLA-4 com a PCM. Para isso, 74 pacientes com PCM e 76 indivíduos controles provenientes de regiões distintas do País tiveram suas freqüências alélicas e genotípicas determinadas. A comparação das freqüências genotípicas e alélicas, entre os grupos pacientes e controles, não mostrou diferenças significativas que pudessem associar o polimorfismo dos SNPs -318 e +49 do gene CTLA-4 com a PCM. A análise dos resultados referentes às freqüências haplotípicas obtidas mostrou que existe um forte desequilíbrio de ligação (D=1) entre os SNPs -318 e +49 para os dois grupos estudados. Porém, a análise realizada não revelou diferenças significativas entre as freqüências haplotípicas dos grupos. Outro ponto importante analisado foi o estudo da estrutura genética (ancestralidade) dos grupos de pacientes e controles. Verificou-se que há predomínio de ancestralidade européia sobre as ancestralidades ameríndia e africana em ambos os grupos. Através desses resultados foi possível determinar que a população utilizada no estudo é geneticamente homogênea, e que o resultado negativo da associação detectado para o gene CTLA-4 e a PCM não está relacionado a ancestralidade da amostragem. Este trabalho demonstra que não foi observada nenhuma associação entre o polimorfismo dos SNPs -318 e +49 do gene CTLA-4 com a resistência e/ou susceptibilidade à Paracoccidioidomicose.
The CTLA-4 protein is mainly expressed in activated T cells and plays an essential role in the immune response through its regulatory effect on T cell activation. This activity is mediated by the binding of CTLA-4 to molecules of the B7 family that are expressed by antigen-presenting cells. Polymorphisms of the CTLA-4 gene have been correlated to several autoimmune pathologies and, more recently, to neoplastic and infectious illnesses. Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic pathogen Paracoccidoides brasiliensis. Its symptoms are associated to various factors, including altered secretion of cytokines, hypergammaglobulinaemia and suppression of cellular immunity. This low…

▼ Inhibitors targeting the CTLA-4 and PD-1 receptors have greatly improved the survival and outcomes of patients with advanced stage melanoma. There are currently numerous Phase 1-3 clinical trials testing the combination of immune checkpoint inhibitors in metastatic melanoma, including drugs targeting IDO1, LAG3, and TIM3. In order to determine which patients will benefit from a specific therapy, it is vital to first identify predictors of response to immunotherapies. This will allow for the administration of personalised immunotherapies and increase the rate of response for metastatic melanoma patients. While many patients exhibit a response to single-agent or combination immune checkpoint blockade, there exists a subgroup of patients who receive minimal or no benefit from these therapies. These patients often do not respond at all (innate resistance) or relapse after demonstrating an initial response (acquired resistance). For these patients, it is of utmost importance to identify potential mechanisms of resistance and ways in which these signalling molecules or pathways may be targeted in order to elicit an anti-tumour immune response. Therefore, the aim of this thesis is to identify biomarkers of response and mechanisms of resistance to anti-PD-1 monotherapy, or combination anti-PD-1 and anti-CTLA-4 immunotherapy in metastatic melanoma patients. The studies described herein employ various experimental techniques including highly quantitative multiplex immunofluorescence, immunohistochemistry, RNA-sequencing, targeted RNA-sequencing and DNA sequencing on FFPE melanoma specimens, as well as mass cytometry on tumour dissociates. Throughout the studies included in this thesis, I identify potential biomarkers of response to anti-PD-1 based therapies at baseline, including an EOMES+ memory T-cell population associated with significantly longer progression-free survival and tumour shrinkage. I further highlight the application of multiplex immunofluorescence in investigating the spatial distribution of critical immune populations and their potential role as biomarkers of response. Finally, I perform a detailed characterisation of the non-responding patients, and identify pathways associated with resistance to anti-PD-1 based therapies. These findings have significant implications for the treatment and selection of metastatic melanoma patients for anti-PD-1 based therapies.

▼ HIV infection remains an important public health
problem worldwide, at the end of 2011 UNAIDS estimated that there
were 34.0 million people living with HIV infection. In addition,
2.5 million people were newly infected with HIV, and there were 1.7
million AIDS-related deaths worldwide. HIV causes a gradual loss of
immune competence, leading to acquired immunodeficiency syndrome
(AIDS). HIV-associated defects in cell-mediated immunity (CMI) are
of particular importance, as these impairments lead to a poor
control of HIV replication and of other pathogens whose clearance
depends on CMI. Notably, a number of immune deficits caused by HIV
infection can be partially restored in vitro. In addition,
persistent immunological dysfunction is observed in HIV-infected
patients under HAART, suggesting the existence of active regulatory
mechanisms. Regulatory T cells (Treg) constitute a subset of CD4+ T
cells that plays a major role in the homeostasis of the immune
system. Compared to healthy individuals, Treg accumulate in the
lymphoid tissues and peripheral blood of HIV-infected individuals,
even in the absence of detectable viral replication. Treg may be
detrimental to the host by substantially decreasing HIV-specific
immune responses during HIV infection. However, Treg may also play
a beneficial role, by controlling immune activation limiting
cellular targets available for HIV infection, as well as decrease
the pathology associated with immune activation in HIV. The role of
Treg in the setting of acute HIV infection and the mechanisms
underlying Treg relative accumulation during HIV infection are
still unclear. First, we hypothesize that Treg could decrease acute
HIV infection of relevant HIV target cells (CD4+T cells and DC),
because of Treg natural ability to decrease T cell activation and
DC maturation, which are crucial processes for a successful HIV
infection and dissemination. Our results indicate that Treg
decreases cell-free and cell-mediated HIV infection of T cells and
DC:Tcon cell clusters. Furthermore, there is a clear involvement of
CTLA-
4 in the Treg-mediated suppression of HIV infection in the
DC;Tcon infection model. Importantly, Treg suppresses HIV infection
in both models in a cAMP-dependent manner, highlighting the
importance of this mechanism in Treg mediated suppression in
different systems. Second, set out to determine the molecular
factors driving Treg persistence during treated chronic
HIV-infection. HAART induces lipid alteration and Treg appear to
primarily depend on lipid oxidation for energy generation. We thus
hypothesize that lipid changes during HAART contribute to the Treg
persistence during treated HIV infection. Increased Treg frequency
in treated HIV-infected individuals was positively associated with
plasma HDL levels. Treg were more efficient at HDL internalization
than naive but not memory CD4+ T cells. Culture of Treg from
healthy donors in the presence of HDL promoted their accumulation;
whereas HDL did not affect naive and memory T cells. Importantly,
the Akt signaling pathway may be…

▼ Le mélanome métastatique reste un enjeu majeur de santé publique. Les avancées fulgurantes de ces dernières années ont permis d’améliorer la prise en charge thérapeutique, notamment avec l’arrivée des anticorps bloquant ou agonistiques ciblant les molécules de co-inhibition ou de co-stimulation. Cependant, certains patients sont réfractaires à tout traitement. Il est donc nécessaire de mettre en évidence l’importance de certains paramètres immunologiques permettant d’améliorer le suivi des patients de stade III à haut risque de récidive. De plus, il est primordial de découvrir des marqueurs prédictifs associés à la réponse à ces différents traitements immunomodulateurs. Nous avons identifié une association entre une fréquence élevée de CD45RA+CD4+ et de CD3-CD56- au sein des métastases ganglionnaires avec la survenue d’une récidive anticipée.Une forte expression de NKG2D à la surface des lymphocytes T CD8+, une faible proportion de Tregs ou une faible expression de PD-L1 à la surface des T circulants sont associées à une meilleure survie. Aussi, la mise en place d’un test in-vitro étudiant les réactivités fonctionnelles des lymphocytes infiltrant les tumeurs a permis de dégager l’importance de l’expression de CD95/Fas sur les T CD4+ circulants et de CD137/4-1BB sur les T CD8+ circulants dans la prédiction de la réponse à l’ipilimumab (anti-CTLA-4) et à la combinaison ipilimumab + nivolumab (anti-PD-1). Par ailleurs, le pattern d’expression des récepteurs de chimiokines à la surface des lymphocytes T périphériques permet de détecter les localisations métastatiques de mélanome. Cette étude a révélé également l’importance biologique de l’axe CCR9/CCL25 dans l’immunosurveillance naturelle anti-tumorale.
Metastatic melanoma (MM) is an unmet medical need. The development of immune checkpoint blockers (ICB) improved patient’s clinical outcomes. However, some patients still do not respond to these therapies. To adress these issues, we must find some immunological parameters which predict the relapse of high risk resected stage III melanoma patients. Moreover, it is an urgent need to identify some predicting parameters to these ICB. In our studies, high frequencies of CD45RA+CD4+ and CD3-CD56- in metastatic lymph nodes are associated with a short relapse-free survival. Higher expression of NKG2D on CD8 T cells, low Tregs and low PD-L1 expression on circulating T cells are associated with a prolonged overall survival.Furthermore, we designed an in-vitro test to assess intratumor lymphocytes reactivities to ICB and cytokines (IL-2 and IFNα2a). Low expression of CD95/Fas on CD4+ circulating T cells and high expression of CD137/4-1BB on circulating CD8+ T cells are associated with the response to ipilimumab (anti-CTLA-4) and to the combination ipilimumab + nivolumab (anti-PD-1), respectively. In addition, the chemokine receptor pattern expressed at the surface of circulating lymphocytes could predict the metastatic spreading of melanoma. In this last study, we demonstrated the critical role of CCR9/CCL25 pathway in the natural…

▼ Gravesâ disease (GD), an organ specific autoimmune disease, requires two signals to activate the T cells. In addition to the specific binding of T cell receptor to the antigenic peptide-MHC complex, an antigen-independent costimulatory pathway reportedly require generate subsequent cytokines and cell surface molecules. This regulation of T-cell response is a highly-organized multiple step program. T cell costimulatory signals is found to regulate the magnitude and duration of various type of autoimmune diseases. This study is to test whether genetic polymorphism of these costimulatory genes is related with the disease susceptibility or progression. We anticipated that the candidate genetic makers are beneficial for importing GD management.
We recruited 262 GD patients from the Outpatient Department of Endocrine and 200 healthy controls from the Health Screening Center of Chang Gung Memorial Hospital in Kaohsiung.The GD patients were divided into three groups: recurred within 9 months (n=91), between 10-36 months (n=65), and more than 36 months (n=106). Clinical and laboratory attributes included: the genotypes of
CTLA-
4, CD28, ICOS, PD-1 and CD40; serum levels of T4, T3 and TSH; goiter size and TSH-receptor antibodies at the beginning and end of treatment. Genomic DNA was extracted from peripheral blood leucocytes by kit. The single nuclotide polymorphisms of the candidate genes were genotyped by polymerase chain reaction- restriction fragment length polymorphism and TaqMan® SNP Genotyping Assays with specific primers. Linkage disequilibuium between pairs of polymorphism was estimated by Haploview software. Haplotype analyses were performed using the Hap-Clustering program. Variance and correlation of data was statistically analyzed by Chi-square, general liner model, multiple logistic regression analysis and Kaplan-Meier plot. A p value <0.01 was considered significant.
The results showed:(1) Genetic polymorphism within the costimulatory molecules affected the susceptibility and progression of GD; (2) GD patients carried more risk alleles than the controls; (3) Within the GD group, patients harboring more risk alleles wound relapse earlier after drug withdrawal; (
4) Number of risk alleles, goiter size and TBII levels at end of treatment were independent predictors of disease relapse; (5) A risk score calculation based on odds ratio of risk alleles correlated with patientsâ relapse time after drug withdrawal.
We concluded that patientsâ genetic makers of costimulatory molecules may be helpful in choosing appropriate treatment for GD.

▼ Poxviruses are characterized by large double stranded DNA genomes that encode numerous proteins tailored for host immune response evasion. Our lab has been investigating a sequence-diverse family of secreted poxvirus proteins that appear to share a conserved beta-sandwich fold, but differ in their immunomodulatory functions. We have termed members of this superfamily Poxvirus Immune Evasion (PIE) proteins, and there appears to be at least 20 distinct subfamilies. As it turns out, cowpox virus (CPXV) encodes 10 PIE proteins, one of which, M2, can inhibit murine T cell activation through specific interactions with co-stimulatory ligands B7. 1 (CD80) and B7. 2 (CD86). Functionally, weնe shown that CPXV M2 selectively blocks murine B7. 2/CD28 interaction. Using surface plasmon resonance (SPR), Iնe demonstrated that CPXV M2 has a preferential interaction with mB7. 2 over mB7. 1 which allows the predominantly inhibitory molecule, mB7. 1, to continue interaction with mCTLA-
4. Cryo-EM analysis of CPXV M2, in complex with human B7s, reveals the formation of both hexameric and heptameric ringed structures linked via intermolecular disulfide bonds. These oligomers are constitutively expressed and secreted with the capability of binding one B7 molecule per monomer. Size exclusion coupled light scatter, native mass spectroscopy, negative stain EM, and native PAGE all support the formation of these oligomeric species in both B7-bound and unbound CPXV M2. Additionally, oligomerization is conserved in at least three other poxvirus M2 analogs (MYXV, YKV, VACV WR), each of which has their own B7 species specificity. Together, our data helps define a novel mechanism by which CPXV exploits cellular ligands to selectively shut down host T cell activation.

▼ CD8+ T cells are vital components to the immune system and serve as crucial effectors in the elimination of infected cells and pathogens. During the course of an immune response many interactions occur among antigen presenting cells and T cells, as well as, eventual contacts between activated T cells and target cells. However, during the stimulation of T cells, interactions exist among T cells themselves. These adhesion molecule mediated T cell activation clusters occur both in vitro and in vivo. Here we demonstrate the role of CD8+ T cell clusters on the eventual effector function and differentiation of CD8+ T cells. Our findings reveal that T cell clusters mediated via ICAM-1:LFA-1 interactions, help to dampen the immune response by regulating expression levels of the effector markers interferon-gamma and granzyme B, as well as, cytotoxicity.
Understanding the mechanisms by which this effector regulation occurs is complex. Our data suggest that unclustered T cells sense an increased amount of antigen as shown through Nur77-GFP studies. In addition, our findings demonstrate a dependence on T cell cluster formation and contact in general for the upregulation of the immune inhibitory protein CTLA-4. CTLA-4 suppresses CD8+ T cell immunity via the downregulation of the transcription factor eomesodermin and thereby regulates the production of both interferon-gamma and granzyme B. Similar effector function studies, under certain conditions, are indeed shown in vivo as well. Thus, T cell clusters regulate the tuning of CD8+ T cell function and terminal differentiation. These studies contribute to our knowledge of the necessity of T cell interactions and crosstalk during priming and potentially, via cluster manipulation, we hope to augment vaccine efficacy and anti-tumor immunotherapeutics.

▼ Multifunctional nanoparticles represent a class of materials with diverse therapy and imaging properties that can be exploited for the treatment of cancers that have significantly progressed or advanced, which are associated with a poor patient prognosis. Here, we describe the use of biodegradable Prussian blue nanoparticles (PBNPs) in combination with anti-
CTLA-
4 checkpoint blockade immunotherapy for the treatment of advanced cancers. Our nanoparticle synthesis scheme yields PBNPs that possess pH-dependent intratumoral stability and photothermal therapy (PTT) properties, and degrade under mildly alkaline conditions mimicking the blood and lymph. Studies using PBNPs for PTT in a mouse model of neuroblastoma, a hard-to-treat cancer, demonstrate that PTT causes rapid reduction of tumor burden and growth rates, but results in incomplete responses to therapy and tumor relapse. Studies to elucidate the underlying immunological responses demonstrate that PTT causes increased tumor infiltration of lymphocytes and T cells and a systemic activation of T cells against re-exposed tumor cells in a subset of treated mice. PBNP-based PTT in combination with anti-
CTLA-
4 immunotherapy results in complete tumor regression and long-term survival in 55.5% of neuroblastoma tumor-bearing mice compared to only 12.5% survival in mice treated with anti-
CTLA-
4 alone and 0% survival both in mice treated with PTT alone, or remaining untreated. Further, all of the combination therapy-treated mice exhibit protection against tumor rechallenge indicating the development of antitumor immunity as a consequence of therapy. Our studies indicate the immense potential of our combination photothermal immunotherapy in improving the prognosis and outlook for patients with advanced cancers.

▼ Purpose: Interferon is approved for adjuvant treatment of patients with stage IIb/III melanoma. The toxicity and uncertainty regarding survival benefits of interferon have qualified its acceptance, despite significant durable relapse prevention in a fraction of patients. Predictive biomarkers that would enable selection of patients for therapy would have a large impact upon clinical practice. Specific CTLA-4 polymorphisms have previously shown an association with response to CTLA-4 blockade in patients with metastatic melanoma and the development of autoimmunity.Experimental design: 286 melanoma patients and 288 healthy controls were genotyped for six CTLA-4 polymorphisms previously suggested to be important (AG 49, CT 318, CT 60, JO 27, JO30 and JO 31). Specific allele frequencies were compared between the healthy and patient populations, as well as presence or absence of these in relation to recurrence. Alleles related to autoimmune disease were also investigated.Results: No significant differences were found between the distributions of CTLA-4 polymorphisms in the melanoma population compared with healthy controls. Relapse free survival (RFS) and overall survival (OS) did not differ significantly between patients with the alleles represented by these polymorphisms. No correlation between autoimmunity and specific alleles was shown. The six polymorphisms evaluated where strongly associated (Fisher’s exact p-values<0.001 for all associations) and significant linkage disequilibrium among these was indicated.Conclusion: No polymorphisms of CTLA-4 defined by the SNPs studied were correlated with improved RFS, OS, or autoimmunity in this high-risk group of melanoma patients.
Σκοπός: Η ιντερφερόνη θεωρείται καθιερωμένη επικουρική θεραπεία σε ασθενείς με κακόηθες μελάνωμα σταδίων ΙΙΒ, ΙΙC και ΙΙΙ. Είναι όμως περιορισμένης αποδοχής λόγω της τοξικότητας και της αβεβαιότητας όσον αφορά το όφελος της επιβίωσης, καίτοι βελτιώνει σημαντικά την ελεύθερη υποτροπής επιβίωση σε μία υποομάδα ασθενών με κακόηθες μελάνωμα. Επομένως, θα ήταν χρήσιμο να κατανοήσουμε καλύτερα τους μηχανισμούς δράσης της ιντερφερόνης άλφα-2b και να αναγνωρίσουμε προγνωστικούς δείκτες που θα μας επιτρέψουν να ξεχωρίσουμε τους ασθενείς που είναι πιθανότερο να ωφεληθούν από τη θεραπεία με IFN-a2b. Ο σκοπός αυτής της μελέτης είναι η αναζήτηση 6 πολυμορφισμών του CTLA-4 και η εκτίμηση της επίδρασης της έκφρασής τους στην επιβίωση ασθενών με μελάνωμα υψηλού κινδύνου οι οποίοι λαμβάνουν επικουρική θεραπεία με ιντερφερόνη υψηλής δόσης (HDI). Μεθοδολογία και ασθενείς: Στη μελέτη περιλήφθηκαν διακόσιοι ογδόντα τέσσερις (284) ασθενείς με μελάνωμα σταδίου ΙΙΒ, ΙΙC και ΙΙΙ και 288 υγιείς μάρτυρες. Περιφερικό αίμα ελήφθη πριν από την έναρξη της επικουρικής ανοσοθεραπείας με ιντερφερόνη. Το DNA απομονώθηκε χρησιμοποιώντας το σύστημα εξαγωγής GenoPrep και για την ανίχνευση των πολυμορφισμών (SNP-PCR) του CTLA-4 (AG 49, CT 60, CT 318, JO 27, JO 30, JO 31 και του HLA-Cw*06) χρησιμοποιήθηκε η αλυσιδωτή αντίδραση της πολυμεράσης.

▼ BACKGROUND: Behcet's Disease disease (BD) is a multisystemic inflammatory disorder. Several reports have suggested that autoimmunity, more precisely, failure to control autoreactive immune cells in the periphery may play a crucial role in BD. To produce a balanced immune response, key inhibitory costimulartory molecules that critically affect peripheral T cell tolerance and T cell function includes the cytotoxic T-lymphocyte antigen-
4 (
CTLA-
4)/CD80, CD86 and programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) receptor/ligand systems are important. Also, regulatory T (Treg) cells play an important role in maintaining immune homeostasis.
PURPOSE: The objective of the present study was to determine the immunopathological implication of costimulatory molecules in BD. I investigated cell surface expression of
CTLA-
4 and PD-1 on T cells and Treg cells, as well as cell surface expression of CD80, CD86, PD-L1 on antigen presenting cells (APCs). Also, I measured the concentration of soluble
CTLA-
4 (sCTLA-
4) from serum and culture supernatants.
MATERIALS AND METHODS: From January 2009 to June 2009, a total of 19 patients with BD were enrolled in this study. The disease control and healthy control (HC) group consisted of age- and sex-matched 8 recurrent aphthous ulcer (RAU) patients without any other evident disease and 10 healthy volunteers, respectively. PBMCs of subjects were cultured and stained with the appropriate fluorescent antibody for analysis by flow cytometry. To measure the sCTLA-
4 concentrations in serum and in culture supernatants, ELISA was performed. To investigate the mRNA expression level of sCTLA-
4 and PD-L1 in PBMCs, real time PCR was performed.
RESULTS: In active BD group, the surface expression of
CTLA-
4 on CD4+ T cells was decreased in the stimulated state compared with HC group. In contrast, the surface expression of PD-1 on CD4+ T cells and
CTLA-
4 on CD8+ T cells did not show significant differences among each group. There were no differences of CD80 expression on APCs among each group, however, the surface expression of CD86 on APCs was impaired in active BD group compared with HC and inactive BD group in unstimulated state. Also, the surface expression of PD-L1 on APCs was decreased in active BD group compared with other group in unstimulated state. In addition, the surface expression of PD-L1 on APCs was decreased not only in active BD group, but also in inactive BD group at 48 hours after stimulation compared with other group. Proportion of CD4+CD25+highFOXP3+ T cells on CD4+ T cells was decreased in active BD group compared with inactive BD group. Significantly decreased percentage of
CTLA-
4 expressing CD4+CD25+high T cells was observed in active BD group compared with HC group in stimulated state, but surface PD-1 expression on CD4+CD25+high T cells did not show any differences among each group. Abnormal high serum concentration of sCTLA-
4 was appeared in active BD group compared with HC group and RAU group. However, after stimulation, significant differences of sCTLA-
4 concentration were…

▼ L’incidence croissante des désordres immunitaires a motivé le développement de nouvelles approches permettant l’induction d’une tolérance immunitaire spécifique et maintenue dans le temps. S’inscrivant dans ce cadre, la vaccination tolérogène exploite les propriétés innées du système immunitaire pour rétablir la tolérance en visant spécifiquement les cellules dendritiques et les lymphocytes T régulateurs. Ce concept se confronte néanmoins à certaines limitations dues au besoin d’apporter l’antigène sous une forme particulière ou de manière combinée avec un signal de tolérance. En exploitant les propriétés natives des pseudo-particules dérivées de rétrovirus, nous avons mis au point une plateforme permettant de répondre à ces problématiques propres à la vaccination tolérogène. Par ce travail de thèse, l’objectif fut de démontrer la faisabilité de cette approche, en produisant et caractérisant des VLP exprimant l’ovalbumine au sein de la capside et présentant le CTLA-4 à leur surface. Par une étude fonctionnelle sur les cellules dendritiques et sur des cellules présentant une spécificité réactionnelle pour l’ovalbumine, nous avons démontré les propriétés tolérogènes de ces VLP. Ces propriétés ont par la suite été confirmées dans un modèle d’allergie alimentaire induite à l’ovalbumine chez la souris. Les résultats obtenus montrent pour la première fois que ces VLP tolérogènes permettent le contrôle de l’allergie alimentaire de manière spécifique et à long terme et fournissent la preuve de concept de leur utilisation. Les travaux entrepris permettent d’envisager l’utilisation de ces particules dans d’autres champs d’application et notamment les maladies auto-immunes.
The increasing incidence of immune disorders has motivated the development of innovative approaches allowing the induction of a specific and long-lasting immune tolerance. Tolerogenic vaccination stands as one of those new therapies and exploits the innate properties of the immune system to restore tolerance by specifically targeting major players such as dendritic cells and regulatory T cells. Nevertheless, this concept faces certain limitations due to the need to provide the antigen in a particular form or in combination with a tolerance signal. By exploiting the native properties of pseudo-particles derived from retroviruses, we have developed a platform to answer those needs. With this thesis research, the objective was to highlight the feasibility of this approach by producing and characterizing VLPs expressing ovalbumin within the capsid and presenting CTLA-4 molecules on their surface. By functional studies on dendritic cells and on ovalbumin specific T cells, we highlight the tolerogenic properties of these VLPs. These properties were subsequently confirmed in a model of ovalbumin-induced food allergy in mice. The obtained results demonstrate for the first time that these tolerogenic VLPs allow the control of food allergy in a specific and long-lasting manner, thus supporting the proof of concept of their use. Additional work also makes it…

▼ Cancer is the second most common cause of death in the United States behind heart disease. While current treatments such as surgery, chemotherapy, and radiation therapy are effective and widely used, medicine is moving towards more targeted and personalized therapies. Immunotherapy is one such treatment that utilizes the patient’s own immune system to target and eliminate tumor cells. It allows for the patient’s adaptive immune system to bypass the self-tolerance mechanisms used by the cancerous cells and be activated against the cancer. Two such self-tolerant mechanisms that are co-opted by tumor cells are the interactions between CTLA-4 and T lymphocytes and the interactions between PD-1 and PD-L1. Blocking these interactions allows for the recruitment of CTLs to the site of the tumor and subsequent attack. CTLA-4 and PD-1 are inhibitory costimulators that play a role in the suppression of the adaptive immune system. The interaction of these receptors with their respective ligands leads to self-tolerance, and is a common mechanism used as a protective measure against autoimmune reactions.
Monoclonal antibodies against these two receptors and ligand have been tested in clinical trials and have shown efficacy against ovarian cancers, non-small cell lung carcinomas, colon cancers, and melanomas. By targeting the inhibitory signals, these monoclonal antibodies expose cancer cells as being “non-self” thus prompting the immune system to attack. Now, studies are focusing on combination therapies, which combine chemotherapeutics or other monoclonal antibodies with PD-1 and CTLA-4 inhibitors to enhance the effectiveness of the drug. However, drawbacks and side effects to the therapy range from fatigue and nausea to development of autoimmune diseases. It brings forward that future studies will need a panel of predictive biomarkers to identify the best candidates for the immunotherapy. While there are many obstacles, such as a lower than expected efficacy of the immunotherapy, the progress made has important implications in the development of personalized medicine.

▼ Osteosarcoma is the most common bone cancer in
children and adolescents. Patients with metastatic osteosarcoma are
typically refractory to treatment. Numerous lines of evidence
suggest that cytotoxic T-lymphocytes (CTL) limit the development of
metastatic osteosarcoma. I have investigated the role of Programmed
Death Receptor-1 (PD-1) in limiting the efficacy of immune mediated
control of metastatic osteosarcoma. I show that human metastatic,
but not primary, osteosarcoma tumors express the ligand for PD-1
(PD-L1) and that tumor infiltrating CTL express PD-1, suggesting
this pathway may limit CTL control of metastatic osteosarcoma in
patients. PD-L1 is also expressed on the K7M2 osteosarcoma tumor
cell line that establishes metastases in mice, and PD-1 is
expressed on tumor infiltrating CTL during disease progression.
Blockade of PD-1/PD-L1 interactions dramatically improves the
function of osteosarcoma-reactive CTL in vitro and in vivo, and
results in decreased tumor burden and increased survival in the
K7M2 mouse model of metastatic osteosarcoma. My results suggest
that blockade of PD-1/PD-L1 interactions in patients with
metastatic osteosarcoma should be pursued as a therapeutic
strategy. However, PD-1/PD-L1 blockade treated mice still succumb
to disease due to selection of PD-L1 mAb resistant tumor cells via
up-regulation of other co-inhibitory T cell receptors.
Combinational α-CTLA-4 and α-PD-L1 blockade
treated mice were able to completely eradicate metastatic
osteosarcoma, and generate immunity to disease. These results
suggest that blockade of PD-1/PD-L1 interactions in patients with
metastatic osteosarcoma, although improves survival, may lead to
tumor resistance, requiring combinational immunotherapies to combat
and eradicate disease.

▼ L'activation de TLR9 par injection directe de nucléotides CpG non méthylés dans une tumeur peut induire une réponse immunitaire thérapeutique, mais les lymphocytes T régulateurs (Tregs) inhibent ensuite la réponse immunitaire antitumorale et limitent ainsi le pouvoir des stratégies d'immunothérapies contre le cancer.Chez des souris porteuses de tumeurs, nous avons constaté que les Tregs dans la tumeur expriment préférentiellement les marqueurs cellulaires de surface CTLA-4 et OX40. Nous montrons que la co-injection intratumorale d'anti-CTLA-4 et anti-OX40 avec du CpG en intra-tumoral aboutit à l’élimination des Tregs infiltrant la tumeur. Cette immunomodulation in situ, réalisée avec de faibles doses d'anticorps dans une tumeur unique, génère une réponse immunitaire antitumorale systémique capable d’éradiquer la maladie disséminée chez la souris. De plus, cette modalité de traitement est efficace contre des lésions de lymphome du SNC avec métastases leptoméningées, des sites qui sont généralement considérés comme des sanctuaires de cellules tumorales pour les traitements systémiques conventionnels.Ces résultats démontrent que les effecteurs immunitaires anti-tumoraux activés par immunomodulation locale peuventt éradiquer des cellules tumorales siègeant dans des sites éloignés. Nous proposons que, plutôt que d'utiliser des anticorps monoclonaux pour cibler les cellules cancéreuses par voie systémique, des anticorps monoclonaux pourraient être utilisés pour cibler les cellules immunitaires infiltrant la tumeur localement, provoquant ainsi une réponse immunitaire systémique.
Activation of TLR9 by direct injection of unmethylated CpG nucleotides into a tumor can induce a therapeutic immune response; however, regulatory T-cells (Tregs) eventually inhibit the antitumor immune response and thereby limit the power of cancer immunotherapies. In tumor-bearing mice, we found that Tregs within the tumor preferentially express the cell surface markers CTLA-4 and OX40. We show that intratumoral coinjection of anti–CTLA-4 and anti-OX40 together with CpG depleted tumor-infiltrating Tregs. This in situ immunomodulation, which was performed with low doses of antibodies in a single tumor, generated a systemic antitumor immune response that eradicated disseminated disease in mice. Further, this treatment modality was effective against established CNS lymphoma with leptomeningeal metastases, sites that are usually considered to be tumor cell sanctuaries in the context of conventional systemic therapy. These results demonstrate that antitumor immune effectors elicited by local immunomodulation can eradicate tumor cells at distant sites. We propose that, rather than using mAbs to target cancer cells systemically, mAbs could be used to target the tumor infiltrative immune cells locally, thereby eliciting a systemic immune response.

▼ La thérapie génique consiste à introduire du matériel génétique dans des cellules dans l’objectif de traiter une pathologie. Le plus souvent, la thérapie génique s’effectue au moyen d’un vecteur viral, transportant le gène jusque dans les cellules cibles. Dans le cas des maladies monogéniques, l’adeno-associated virus (AAV) s’est imposé progressivement comme un vecteur de choix. Son absence de pathogénicité, son large tropisme et sa capacité à transduire des cellules quiescentes sont autant d’avantages comparés à d’autres vecteurs utilisés en thérapie génique. L’utilisation d’AAV est approuvé en Europe pour le traitement d’un déficit rare en lipoprotéine lipase et vient récemment d’être approuvé par les autorités américaines pour le traitement d’un déficit de la vision. Toutefois, les essais de thérapies géniques se heurtent souvent aux réponses immunitaires dirigées contre l’AAV. En effet, les différents composants de ce vecteur viral ont été identifiés comme pouvant déclencher des réponses immunitaires s’opposant à l’efficacité à long terme de la thérapie génique. De plus, la protéine transgénique peut s’avérer immunogène, ce qui conduit au déclenchement de réponses immunitaires, à la destruction des cellules transduites et in fine à l’échec de la thérapie génique. En clinique, des immunosuppresseurs sont utilisés pour palier à ses effets indésirables. Toutefois, de par leurs effets secondaires infectieux et tumorigènes, des stratégies visant plutôt à induire de la tolérance vis-à-vis de la protéine transgénique, associées à un bénéfice pour la santé des patients, se sont développées.L’objectif de ce travail de thèse a été d’implémenter une nouvelle stratégie visant à étudier l’effet immunorégulateur et tolérogène de protéines de fusion dérivées de CTLA-4/Fc et de PD-L1/Fc. Pour cela, nous avons utilisé un modèle murin récapitulant les réponses immunitaires induites par un AAV permettant l’expression d’une protéine modèle fortement immunogène, l’ovalbumine (Ova). Ensuite, des AAV codant pour les protéines au potentiel immunorégulateur ont été synthétisés et injectés aux souris conjointement à l’AAV-Ova. Cette stratégie d’immunorégulation vectorisée (VIR) nous a permis d’évaluer la capacité de chacune des protéines à moduler les réponses immunitaires dirigées contre l’Ova directement in vivo. Au total, ce travail a permis de mettre en évidence i) l’intérêt et les limites de la stratégie VIR, ii) celui du rôle délétère de CTLA-4/Fc au long terme sur les lymphocytes Tregs CD4+FoxP3+, périphériques et centraux, iii) et de démontrer l’intérêt de 2 nouvelles molécules dérivées PD-L1/Fc sur la persistance de l’Ova.

▼ Melanoma is the most malignant form of skin cancer. The five-year survival rate for metastatic melanoma is 19.9%. Although targeted therapy of BRAF and MEK inhibitors were developed for melanoma, resistance to therapy is inevitable. Immune checkpoint blockade, which reverses the suppression of the immune system, on the other hand, has shown a durable response in 20-30% of patients with metastatic melanoma. However, more predictive and robust biomarkers of response to this therapy are still needed, and resistance mechanisms remain incompletely understood. To address this, we examined a cohort of metastatic melanoma patients treated with sequential checkpoint blockade against cytotoxic T lymphocyte antigen–
4 (
CTLA-
4) followed by programmed death receptor–1 (PD-1) by immunogenomic profile analyses from serial tumor biopsies.
From immune profiling (12 marker immunohistochemistry and NanoString Gene Expression Profiling), we found that adaptive immune signatures in tumor biopsies obtained from early on-treatment time points are predictive of response to immune checkpoint blockade. We also demonstrated differential mechanistic signatures of tumor microenvironment induced by
CTLA-
4 and PD-1 blockade. Importantly, VEGFA was identified as a potential target of combination therapy withPD-1blockade.
From genomic profiling (whole exome sequencing and T cell receptor sequencing), we demonstrated that a higher TCR clonality in pre-treatment biopsy was predictive of response to PD-1 but notCTLA-4blockade. We also observed increased TCR clonality after
CTLA-
4 blockade treatment in patients responding to the following PD-1 blockade treatment. Analysis of copy number alterations (CNAs) identified a higher burden of copy number loss in nonresponders to
CTLA-
4 and PD-1 blockade and found that it was associated with decreased expression of genes in immune-related pathways. The effect of mutational load and burden of copy number loss on response was nonredundant, suggesting the potential utility of these as a combinatorial biomarker to optimize patient care with checkpoint blockade therapy.
In summary, our integrative cancer immunogenomic analysis shows that genomic and immune profiling of longitudinal tumor biopsies can identify novel biomarkers and resistance mechanisms of immune checkpoint blockade.

▼ Purpose: Interferon is approved for adjuvant treatment of patients with stage llb/lll melanoma. The toxicity and uncertainty regarding survival benefits of interferon have qualified its acceptance, despite significant durable relapse prevention in a fraction of patients. Predictive biomarkers that would enable selection of patients for therapy would have a large impact upon clinical practice. Specific CTLA-4 polymorphisms have previously shown an association with response to CTLA-4 blockade in patients with metastatic melanoma and the development of autoimmunity. Experimental design: 286 melanoma patients and 288 healthy controls were genotyped for six CTLA-4 polymorphisms previously suggested to be important (AG 49, CT 318, CT 60, JO 27, JO 30 and JO 31). Specific allele frequencies were compared between the healthy and patient populations, as well as presence or absence of these in relation to recurrence. Alleles related to autoimmune disease were also investigated. Results: No significant differences were found between the distributions of CTLA-4 polymorphisms in the melanoma population compared with healthy controls. Relapse free survival (RFS) and overall survival (OS) did not differ significantly between patients with the alleles represented by these polymorphisms. No correlation between autoimmunity and specific alleles was shown. The six polymorphisms evaluated where strongly associated (Fisher’s exact p-values<0.001 for all associations) and significant linkage disequilibrium among these was indicated. Conclusion: No polymorphisms of CTLA-4 defined by the SNPs studied were correlated with improved RFS, OS, or autoimmunity in this high-risk group of melanoma patients.
Σκοπός: Η ιντερφερόνη θεωρείται καθιερωμένη επικουρική θεραπεία σε ασθενείς με κακοήθες μελάνωμα σταδίων IIB, IIC και III. Είναι όμως περιορισμένης αποδοχής λόγω της τοξικότητας και της αβεβαιότητας όσον αφορά το όφελος της επιβίωσης, καίτοι βελτιώνει σημαντικά την ελεύθερη υποτροπής επιβίωση σε μία υποομάδα ασθενών με κακοήθες μελάνωμα. Επομένως, θα ήταν χρήσιμο να κατανοήσουμε καλύτερα τους μηχανισμούς δράσης της ιντερφερόνης άλφα-2b και να αναγνωρίσουμε προγνωστικούς δείκτες που θα μας επιτρέψουν να ξεχωρίσουμε τους ασθενείς που είναι πιθανότερο να ωφεληθούν από τη θεραπεία με IFN-a2b. Ο σκοπός αυτής της μελέτης είναι η αναζήτηση 6 πολυμορφισμών του CTLA-4 και η εκτίμηση της επίδρασης της έκφρασής τους στην επιβίωση ασθενών με μελάνωμα υψηλού κινδύνου οι οποίοι λαμβάνουν επικουρική θεραπεία με ιντερφερόνη υψηλής δόσης (HDI).

▼ Helicobacter pylori (H. pylori) is a gastric pathogen
infecting more than half the world’s population. H. pylori
infection induces gastric inflammation but the host fails to
generate protective immunity. It has been established that
infection lasts for the life of the host despite the induction of
inflammation and adaptive immune responses. It has also previously
demonstrated that protective immunity is CD4+ T cell-dependent
while CD4+ T cells remain hyporesponsive during chronic infection.
Therefore, we evaluated the immunologic mechanisms that contribute
to the failure of the CD4+ T cells to promote active immunity to H.
pylori in the murine model of H. pylori infection. We demonstrate
here that the H. pylori-specific T cells are predominantly anergic.
We provide in vitro and in vivo evidence that while CD25+
regulatory T cells are required to induce this anergic state in
bystander CD25- cells, the CD25- T cells remain hyporesponsive even
when the regulatory T cells have been removed. Interestingly, even
CD25- cells that arise in the absence of regulatory T cells and
therefore are capable of promoting eradication of H. pylori can be
down-regulated when combined with regulatory T cells. These results
demonstrate that CD25+ regulatory T cells not only influence naïve
CD25- cells but may also limit the response of previously-activated
CD25- cells. Finally, we address the mechanism by which the anergic
state is induced by showing that
CTLA-
4 engagement on the surface
of CD25+ regulatory T cells plays a critical role in the H. pylori
immune response. These findings demonstrating functional
inactivation are in accord with the success of therapeutic
immunization in which protective immunity is permitted to develop
in the face of active chronic inflammation resulting from initial
infection. Based on data presented in this thesis, we hypothesize
that
CTLA-
4 expression by CD25+ regulatory T cells induces anergy
in bystander CD25- responder cells resulting in a reduced immune
response and persistent infection.

▼ Le syndrome d'Evans est défini par l'existence concomitante ou séquentielle de cytopénies auto-immunes, le plus souvent, anémie hémolytique et thrombopénie immunologique. Chez l'enfant, il peut être secondaire à une infection, une maladie auto-immune systémique ou un déficit immunitaire primitif. Alternativement, chez une grande partie des patients, l'étiologie n'est pas clairement identifiée. Les patients atteints de syndrome d'Evans présentent parfois d'autres atteintes, telles une auto-immunité d'organe, une lymphoprolifération bénigne ou un déficit immunitaire. L'objectif de ce travail était d'identifier des causes génétiques chez des enfants présentant un syndrome d'Evans sans étiologie sous-jacente identifiée. Nous avons centré notre étude sur des formes sévères à début pédiatrique en faisant l'hypothèse qu'une maladie monogénique serait plus fréquente dans ce groupe de patients. Nous avons mis à profit les technologies de séquençage haut débit « nouvelle génération » (NGS) pour réaliser et analyser le séquençage de l'exome de patients et de certains de leurs apparentés afin de mettre en évidence des gènes candidats potentiels. Ce travail a permis l'identification de
4 gènes candidats : LRBA,
CTLA-
4, STAT3 (mutations gain de fonction) et NFKBIA. L'implication des 3 premiers gènes dans de nouvelles maladies monogéniques où l'auto-immunité est au premier plan a été confirmée par d'autres équipes au cours de ce travail. Pour chacun de ces gènes, nous avons poursuivi 2 objectifs complémentaires : d'une part, tenter de valider l'implication des gènes identifiés dans la maladie des patients. Nous avons pour cela utilisé des approches et techniques variées : biochimie et protéomique afin d'identifier des partenaires protéiques, microscopie confocale pour localiser les protéines et leurs interactions, tests cellulaires in vitro pour mettre en évidence un défaut fonctionnel, marquages en cytométrie en flux pour identifier des modifications dans les sous-populations lymphocytaires. D'autre part, nous avons recherché d'autres mutations de ces gènes chez des patients de phénotype clinique similaire. Nous avons ainsi constitué et exploré 3 cohortes de patients présentant des mutations de LRBA,
CTLA-
4 ou STAT3. Nous avons rassemblé une cohorte de 18 patients porteurs d'une mutation de LRBA, répartis dans 11 familles. Cela nous a permis de préciser et d'étendre le spectre clinique de cette maladie de découverte récente, avec en particulier des atteintes articulaires sévères s'associant à un diabète précoce, ou des entéropathies. Nous avons identifié 15 nouvelles mutations de transmission autosomique récessive dans le gène LRBA, codant une protéine de fonction inconnue dont l'absence entraine une maladie principalement caractérisée par une poly-auto-immunité. Nous avons identifié 29 partenaires protéiques potentiels de LRBA et précisé la localisation de LRBA dans les différents compartiments cellulaires. Nous avons également établi une cohorte de 12 patients dans 10 familles présentant un déficit en

TUMOR IMMUNOTHERAPY: MECHANISMS OF ACQUIRED RESISTANCE AND CHARACTERIZATION OF IMMUNE RELATED TOXICITIES.

▼ Tumor immunotherapy has shown very promising clinical benefit across an array of cancers; however, two major challenges remain unresolved in the field. First, many patients do not respond to therapy at all or relapse after a period of remission. Second, there are often dose-limiting immune related adverse effects associated with immunomodulation.
In order to understand the mechanisms employed by tumors to evade immunotherapeutic responses, we established a murine model of melanoma designed to elucidate the molecular mechanisms underlying immunotherapy resistance. Through multiple in vivo passages, we selected a B16 melanoma tumor line that evolved complete resistance to combination blockade of
CTLA-
4, PD-1, and PD-L1, which cures ~80% of mice bearing the parental tumor. Using gene expression analysis, and immunogenomics, we determined the adaptations engaged by this melanoma to become completely resistant to triple combination T cell checkpoint blockade. Acquisition of immunotherapy resistance by these melanomas was driven by the coordinated upregulation of the glycolytic, oxidoreductase, and mitochondrial oxidative phosphorylation pathways to create a metabolically hostile microenvironment wherein T cell functions are suppressed. Together these data indicate that by adapting a hyper-metabolic phenotype, melanoma tumors can achieve resistance to T cell checkpoint blockade allowing them to escape host immune control.
Increasing the potency of antitumor immunity with immunotherapy disrupts the tightly controlled state of immunologic homeostasis in the body which can lead to reactivation of peripherally-tolerized T cell responses with the potential to mediate uninvited toxicities. Agonist antibodies targeting the T cell co-stimulatory receptor
4-1BB (CD137) are among the most effective immunotherapeutic agents across pre-clinical cancer models. Clinical development of these agents, however, has been hampered by dose-limiting liver toxicity. Lack of knowledge of the mechanisms underlying this toxicity has limited the potential to separate
4-1BB agonist driven tumor immunity from hepatotoxicity. The capacity of
4-1BB agonist antibodies to induce liver toxicity was investigated in wild type and genetically-modified immunocompetent mice. We find that activation of
4-1BB on liver myeloid cells is essential to initiate hepatitis. Once activated, these cells produce interleukin-27 that is required for liver toxicity. CD8 T cells infiltrate the liver in response to this myeloid activation and mediate tissue damage. Co-administration of
CTLA-
4 and/or CCR2 blockade may minimize hepatitis, but yield equal or greater antitumor immunity.
