Transcriptional Analysis Of Cervical Epithelial Cell Responses To Hiv-1, Andrew A. Block
Transcriptional Analysis Of Cervical Epithelial Cell Responses To Hiv-1, Andrew A. Block
School of Biological Sciences: Dissertations, Theses, and Student Research
Human Immunodeficiency Virus type 1 (HIV-1) infection causes a growing pandemic throughout the world, of which women comprise 51% of people who live with HIV-1, more than 60% in sub-Saharan Africa. HIV-1 infections of women are mainly acquired through female reproductive tract where cervical and vaginal epithelial cells are the first line of defense. Although HIV-1 does not directly infect epithelial cells, HIV-1 obligatorily interacts with and crosses over epithelial layer to infect susceptible target cells, mainly CD4+ T cells, in the lamina propria to initiate an infection. However, the mechanism and ramification of the interaction of HIV-1 and epithelial …
Characterization Of Binding And Fusion Efficiencies Mediated By The V1-V5 Env Derived From Transmitted And Non-Transmitted Viruses Isolated From A Perinatal Transmission Cohort From Zambia, Mackenzie Waltke
School of Biological Sciences: Dissertations, Theses, and Student Research
Human Immunodeficiency Virus Type 1 (HIV-1) is the etiological agent of acquired immunodeficiency syndrome (AIDS), which affects over 34 million people worldwide. In sub-Saharan Africa where access to antiretroviral therapies (ART) is limited, mother-to-child transmission (MTCT) rates remain high and represent a major concern in the global HIV/AIDS epidemic. Little is known about the biological properties of viruses that are transmitted perinatally, including how the biological functions of envelope (Env) influence transmissibility. Previously, transmitted viruses were found to have an advantage in replicative fitness mediated by Env V1-V5. In this study viruses derived from transmitting mother infant pairs (MIPs) were …
