"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."

Cell-associated HIV mucosal transmission: The neglected pathway

Dr. Deborah Anderson from Boston University School of Medicine and her colleagues are challenging dogma about the transmission of HIV. Most research has focused on infection by free viral particles, while this group proposes that HIV is also transmitted by infected cells. While inside cells, HIV is protected from antibodies and other antiviral factors. Anderson chides fellow researchers for not using cell-associated HIV in their transmission models: "The failure of several recent vaccine and microbicide clinical trials to prevent HIV transmission may be due in part to this oversight." . The Journal of Infectious Diseases (JID) has devoted their December supplement to this important and understudied topic.

Semen directly impairs effectiveness of microbicides that target HIV

Most microbicides work by targeting the virus itself, attempting to break it down or blocking its ability to infect a cell. However, the heightened infectiousness of HIV in the presence of semen appears to over-power any anti-viral effects the microbicides possess. The one exception to this finding is a different type of microbicide that acts on the host cells' receptors, stopping the virus from latching on from within. In the current study, this microbicide, [containing the drug called] called Maraviroc, was equally effective in preventing infection both with and without the presence of semen.
