Interleukin-7 Facilitates HIV-1 Transmission to Cervico-Vaginal Tissue ex vivo
The majority of HIV-1 infections in women occur through vaginal intercourse, in which virus-containing semen is deposited on the cervico-vaginal mucosa. Semen is more than a mere carrier of HIV-1, since it contains many biological factors, in particular cytokines, that may affect HIV-1 transmission. The concentration of interleukin (IL)-7, one of the most prominent cytokines in semen of healthy...
متن کاملA potential role for tissue kallikrein-related peptidases in human cervico-vaginal physiology.
Human tissue kallikrein-related peptidases (KLK) are a family of 15 genes located on chromosome 19q13.4 that encode secreted serine proteases with trypsin- and/or chymotrypsin-like activity. Relatively large levels of many KLKs are present in human cervico-vaginal fluid (CVF) and in the supernatant of cultured human vaginal epithelial cells. Many KLKs are also hormonally regulated in vaginal ep...
متن کاملCharacterization of a new use for acyclovir and tenofovir using human cervico- vaginal tissue ex vivo
Background: HSV-2, one of the most common HIV-1 copathogens, establishes a synergistic interaction with HIV-1. Several clinical trials have shown that the anti herpetic drug acyclovir decreases HIV-1 viral load and delays HIV-1 disease progression. Similarly, CAPRISA004 reported that a vaginal gel containing 1% of the anti-HIV-1 drug tenofovir unexpectedly decreases the risk of HSV-2 acquisitio...
متن کاملMarkers of local immunity in cervico-vaginal secretions of HIV infected women: implications for HIV shedding.
OBJECTIVES To link local proinflammatory cytokines with HIV related nucleic acids in cervico-vaginal secretions and the factors associated with them. METHODS An observational study on 60 HIV positive women attending the department of obstetrics and gynaecology, University of Pavia, Italy. HIV-1 RNA in plasma, proviral HIV-1-DNA, cell associated and cell free HIV-1 RNA in cervico-vaginal secre...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
