Non-stick protein coating in semen cuts HIV infection (potential ingredient for microbicides)

Published: September 24, 2010

The non-stick coating of protein in semen cuts the rate of infection of immune cells by HIV, a new study has found.

The new material is a potential ingredient for microbicides designed to reduce transmission of HIV, found a team from the University of Rochester Medical Center and the University of California, San Diego.

The coating clings to fibrous strings and mats of protein called SEVI-for semen-derived enhancer of viral infection-which was first discovered just three years ago.
