The Effect Of Hiv-1 Infection Associated Bacterial Lipopolysaccharide (Lps) On Human Oral Keratinocytes: Implications For Promoting Chronic Inflammation, Md Shafayat Jamil

Theses and Dissertations

Human immunodeficiency virus type 1 (HIV-1) remains a major global health concern, affecting approximately 39 million people worldwide, with 500,000 new infections reported in 2022. While combined antiretroviral therapy (cART) has significantly reduced viral replication, HIV-1 infection is linked to various comorbidities, including oral dysbiosis and accelerated aging. Immune dysregulation in HIV-1–infected individuals promotes the proliferation of pathogenic gram-negative bacteria like Porphyromonas gingivalis, a key contributor to periodontal disease. P. gingivalis secretes lipopolysaccharide (LPS), which adversely affects human oral keratinocytes (HOK), the first line of defense against microbial threats in the oral cavity. HOK recognize LPS as a threat, …

Drug-Target Binding Affinity Prediction With Graph-Based Models: The Impact Of 3d Structural Information, Angel Antonio Peredo

Identification Of Cadmium As A Structural And Functional Modulator Of Psd-95 Regulating Nmdars At Postsynaptic Membranes, Claudia Garza

Theses and Dissertations

Postsynaptic density-95 (PSD-95) is an essential scaffolding protein in excitatory neurons. PSD-95’s N-terminal palmitoylation region elicits synaptic plasticity by targeting, anchoring, and trafficking glutamate receptors, such as N-methyl-d-aspartate receptors (NMDAR), to the postsynaptic membrane. The molecular interactions of PSD-95 and its dysregulation in excitatory synapses are currently being explored as primary causes of neurodegenerative diseases and disorders, such as Alzheimer’s disease, Schizophrenia, and Parkinson’s disease. Recent studies demonstrate an overaccumulation of zinc at two cysteines (C3 and C5) and two histidines (H24 and H28) of PSD-95 blocks palmitoylation, causing a loss of NMDAR at the postsynaptic membrane. In addition, exposure …
