A blood thinning agent is helping researchers understand more about the body’s natural barriers to HIV. New research reveals how the protein langerin, which is present in genital mucous and acts as a natural HIV barrier during the first stages of contamination, interacts with the drug heparin.A Blood thinning agent is helping researchers at the University of East Anglia understand more about the body's natural barriers to HIV.
The research team has been able to identify two different mechanisms for that interaction -- involving different sites or 'faces' at the surface of the langerin protein.Lead researcher Dr Jesus Angulo from UEA's school of Pharmacy said: "Langerin is produced by immune cells which are present in genital mucous. They constitute the first obstacle that the HIV virus finds in its way to infecting someone.
"Heparin is widely used as an anticoagulant agent that prevents the formation of blood clots. But it is also occurs naturally in the body with different compositions and surrounds our cells.
"Langerin-heparin interactions are thought to be important in the degradation of the HIV virus. The way that heparin interacts with langerin is important because it is thought to stabilize the formation of granules that facilitates the elimination of HIV particles.
"This is a basic research study providing structural details of a potentially relevant interaction in a known natural barrier to HIV. Yet, of course, it doesn't mean that taking heparin or other anticoagulant drugs will protect people from HIV.
"The ultimate aim of this line of research is to develop drugs that inhibit the HIV cellular receptors that facilitate infection, without inhibiting, or even better boosting, the activity of langerin.
