1. Kearns, Alison Catherine. A Multi-model Approach for Evaluating Caspase-1 Activation in Human Immunodeficiency Virus associated Atherosclerosis and Vascular Neurocognitive Disorders.

Degree: PhD, 2018, Temple University

Biomedical Sciences

Combination antiretroviral therapy (cART)-treated people living with human immunodeficiency virus (HIV) (PLWH) face an increased risk of atherosclerosis associated cardiovascular disease (ASCVD) even after controlling for traditional and non-traditional risk factors (Freiberg et al. 2013). Persistent HIV-associated immune activation (monocyte and T-cell activation) is believed to contribute to heightened complications of ASCVD including, myocardial infarction (MI), and stroke in PLWH (Hsue et al. 2009; Kearns et al. 2017). Specifically, systemic immune activation predisposes PLWH to arterial inflammation (characterized by increased arterial macrophage infiltration), and accelerated atherogenesis (Lo et al. 2010; Burdo, Lo, et al. 2011; Fitch et al. 2013; Subramanian et al. 2012; Tawakol et al. 2016). Accelerated atherogenesis has even been noted among elite controllers, or PLWH who maintain undetectable virus levels in the absence of cART (Pereyra et al. 2012), suggesting that the proc

2. Putatunda, Raj. HIV-1 INFECTION OF NEURAL STEM CELLS RESULTS IN COGNITIVE DEFICITS THROUGH ADULT NEUROGENIC MODULATION.

Degree: PhD, 2018, Temple University

Biomedical Sciences

While antiretroviral therapy (ART) regimens have significantly decreased the mortality rate in patients with HIV-1 infection and subsequent opportunistic infections, the co-morbidities continue to rise. Some of these co-morbidities include cardiomyopathies, metabolic dysfunction, accelerated aging, and most notably, neurocognitive deficits. HIV-1 associated neurocognitive disorders (HAND) denote a spectrum of neurocognitive deficits that are either asymptomatic in nature (asymptomatic neurocognitive impairments, ANI), mild to moderate in intensity (mild neurocognitive disorders, MND), or robust in nature (HIV-associated dementia, HAD). Thanks to the development of ART regimens, the incidence of HAD dramatically decreased. However, the emergence of ANI and MND continues to increase in the HIV-1 patient population. While the multifaceted nature behind the central nervous system (CNS) neuropathology of HIV-1 infection is not completely understood, dysregulated blood-brain barrier (BBB) integrity and the “Trojan-Horse” type mechanism of HIV-1 infection have been proposed as the cellular mechanisms underlying HAND. HIV-1 infects CD4+ T-lymphocytes and monocytes in the peripheral circulatory system. After these infected cells cross the BBB into the CNS, they release toxic viral proteins and viral particles onto microglia and astrocytes. These glial cells become activated, and release a plethora of inflammatory cytokines that further damage neurons via dysregulated neurotransmitter homeostasis, synaptodendritic damage, and calcium-mediated apoptotic pathways. At the same time, the virus may establish a state of latency in these microglia, perivascular macrophages, and astrocytes, which would allow for the long-term persistence of HIV-1 in the CNS. Recently, several studies have demonstrated that neural stem cells (NSCs) are capable of being productively and latently infected with HIV-1. This may be due to the fact that the hippocampal subgranular zone (SGZ), the subventricular zone (SVZ), and the circumventricular organs are highly vascularized, allowing potential direct contact of HIV-1 with NSCs. Additionally, the “Trojan” T-cells and macrophages could possibly release viral particles directly onto NSCs, and also transmit the virus through the formation of immunological synapses with NSCs. Therefore, the central hypothesis in this dissertation is that NSCs may serve as a novel CNS reservoir through which HIV-1 infection persists, and subsequently lead to neurocognitive impairments through dysregulating adult neurogenesis. Adult neurogenesis is a dynamic process that describes the generation of new neurons and glial cells from NSCs and neural progenitor cells (NPCs). This process mainly takes place in two areas of the brain: the SVZ around the lateral ventricles, and the SGZ within the dentate gyrus of the hippocampus. New neurons generated in these two neurogenic niches integrate into their respective circuitries to modulate olfactory stimuli and aid in memory acquisition/consolidation processes.…
