Thesis (Ph.D.)--University of Toronto (Canada), 2018.

Genital inflammation is a key determinant of human immunodeficiency virus (HIV) transmission and may increase the availability of HIV-susceptible target cells at sites of exposure. The African, Carribean, and other black (ACB) community is at increased risk of HIV acquisition in Toronto and several genital conditions that increase HIV risk are also more prevalent, including bacterial vaginosis, herpes simplex virus type-2 (HSV-2) and human papillomavirus (HPV) infection. Therefore, we assessed the impact of these three genital conditions on mucosal immune cells and cytokines in the female genital tract of ACB women. Endocervical cells and cervicovaginal secretions were collected by cytobrush and Instead Softcup, respectively. T cells and dendritic cells were assessed by flow cytometry, proinflammatory cytokines and chemokines by multiplex enzyme-linked immunosorbent assay (ELISA), and the microbiota by 16S ribosomal ribonucleic acid gene sequencing. HSV-2 infection was associated with elevated levels of endocervical HIV target cells (CCR5+ CD4 T cells), Lactobacillus -deficient microbiota was associated with elevated proinflammatory cytokines, prevalent HPV infection was associated with Lactobacillus -deficient microbiota, and HPV clearance was associated with higher numbers of Langerhans cells in the female genital tract. These results suggest multiple ways in which genital conditions are associated with factors that have been shown to influence HIV susceptibility and provides novel targets for future HIV prevention strategies.
