Despite ongoing efforts, sub-Saharan Africa faces a higher cervical cancer burden than anywhere else in the world. Besides HPV infection, definitive factors of cervical cancer are still unclear. Particular states of the cervicovaginal microbiota and viral infections are associated with increased cervical cancer risk. Notably, HIV infection, which is prevalent in sub-Saharan Africa, greatly increases risk of cervicovaginal dysbiosis and cervical cancer. To better understand and address cervical cancer in sub-Saharan Africa, a better knowledge of the regional cervicovaginal microbiome is required This review establishes current knowledge of HPV, HIV, cervicovaginal infections, and the cervicovaginal microbiota in sub-Saharan Africa. Because …

Human immunodeficiency virus (HIV) infection of CD4+ T cells results in a weakened immune system due to decreased white blood cells, particularly multi-lobed neutrophils (neutropenia) and other granulocytes.1 The purpose of this study was to determine whether a correlation exists between HPV/HIV status and presence of neutrophils. To test this, we used a computer software program (QuPath) to analyze neutrophil infiltration seen in pap smears of both HIV+ and HIV- patients from samples collected in Tanzania from three different sites: Bagamoyo, Chalinze, and Dar es Salaam. The software was used to quantify neutrophils per image based on the size …

Abstract:
Papillomaviruses (PVs) are double stranded (ds)-DNA viruses (~8-kbp), which infect mucosal and cutaneous epithelial cells from various mammalian species, causing tumors in both epithelial cell-types. During the late-phase, the capsid proteins (L1 and L2), are expressed to encapsidate the viral genome generating infectious virion particles required for PV. Natural PV infections produce morphologically homogenous progeny virions 55-nm in diameter. Transient transfection systems allow individual expression of the capsid proteins, which are able to produce low-levels of infectious virion-like particles (VLPs) and non-infectious VLPs that have the capacity to resemble and function as wild-type virions.
