AUSTIN, Texas - U.S. and Mexican researchers said they
had developed a vaginal cream that protects against HIV for 72 heures.Cette
cream containing silver nanoparticles that prevent the virus from entering
cells.
Ointment , the protective mechanisms act less than a minute after application, is also effective against other sexually transmitted diseases, according to scientists.
Humberto Lara Villegas , a specialist in nanoparticles and virology at the University of Monterrey in Mexico , worked in collaboration with researchers from the University of Texas. He stressed that this cream helps combat HIV quite different than the usual treatments .
"Traditional drugs prevent the virus from replicating in cells , whereas the nanoparticles contained in this cream directly address HIV and prevent them from entering cells ," said Humberto Lara Villegas .
Researchers have tested the cream on human tissues , and experience has shown that it prevents transmission of the virus through vaginal mucosa. Tests are being conducted on mice, but scientists hope to conduct clinical tests on humans soon.
