In the ex vivo human skin explant model, although immature immune cells known as Langerhans cells (LCs) captured HIV, they did non efficiently air the virus to T cells, something that is essential for the innovation of full disease. By contrast, effective virus transmitting was ascertained if LCs were activated by inflammatory stimuli. As the infectious agents that cause the STDs thrush and gonorrhea triggered the same inflammatory stimuli in vaginal and skin explants, the authors suggest that in the presence of an STD-causing infectious agent, LCs power become activated, thereby increasing an individual's risk of becoming infected with HIV. Further, these data paint a picture that antiinflammatory therapies mightiness provide a way to prevent HIV transmission.
