Have sex workers revealed a connection between semen exposure and HIV resistance?

In a new study, scientists at The Wistar Institute have found that continued semen exposure in these sex workers sustains changes in the cervical and vaginal microenvironment in a way that may actually increase HIV-1 resistance. This information may lead the way to better preventative strategies that block the transmission of the virus and improved designs for future HIV vaccine studies that can monitor the described changes when recruiting sex workers into vaccine trials.

Superhero Vaginal Bacteria Species Traps HIV, Could Be a Natural Condom Someday

The benevolent powers of the vaginal microbiome are even greater than we thought. In addition to aiding fertilization and protecting fetuses during pregnancy, healthy vaginal mucus that’s full of good bacteria can trap and immobilize HIV particles. The study examined the cervicovaginal mucus, or CVM, of 31 women and tested its ability to immobilize HIV particles. CVM samples that contained higher concentrations of D-lactic acid, which only bacteria can produce, did far better than others. The D-lactic acid wasn’t itself a barrier to HIV, but an indicator of something else going on that made certain types of CVM better at trapping the virus than others. That something was Lactobacillus crispatus, a species of bacteria that could change the way we think about HIV prevention.

Infection with multiple HIV-1 variants leads to poorer clinical outcomes

HIV-1 infection with multiple founder variants points to poorer clinical outcomes than infection with a single variant, according to a paper published today in Nature Medicine. In the study researchers analyzed large sample sets from two important HIV vaccine efficacy trials -- the Step HIV vaccine clinical trial (HVTN 502) and RV144, the landmark vaccine clinical trial conducted in Thailand -- to evaluate whether genetic characteristics of the founder viral populations could influence markers of clinical outcomes.

PrEP data links anti-HIV immune response to reduce chance of infection

"The rigor of the placebo-controlled iPrEx trial gave us access to the necessary data and specimens to address that question. What we found was what people have been looking for, for a long time - a correlation between future infection risk and a measureable immune response."

Menopause linked to decreased anti-HIV activity

Postmenopausal women’s cervicovaginal fluid had lower anti-HIV-1 activity than premenopausal women. Timing of menstrual cycle and hormonal contraception were not associated with differences in activity against HSV or HIV.
