Prevalent Chronic Infections Modulate T-Cell Phenotypes And Functions Enhancing Hiv Susceptibility, Dissemination, And Persistence In African Population, Thomas F. Marandu, Mkunde S. Chachage

Tanzania Journal of Science

While many studies have associated HIV prevalence with socio-economic status, few have explored the host's immunity status prior to HIV infection. High HIV prevalence in Africa may in part be contributed by a high prevalence of other persistent infections that modulate the host immunity towards phenotypes that promote HIV acquisition. In this narrative review, we examined how four most prevalent pathogens in Africa (human papillomavirus, herpesviruses, Mycobacterium tuberculosis, and helminth infections) modulate immunity to favor their survival and in turn, also influence HIV acquisition. We have described how these pathogens expand the number of memory and activated T cells, increase …
