[HIB]Protein that destroys HIV discovered

Loyola University researchers have identified the key components of a protein called TRIM5a that destroys HIV in rhesus monkeys. The finding could lead to new TRIM5a-based treatments that would knock out HIV in humans, said senior researcher Edward M. Campbell, PhD, of Loyola University Health System. Campbell and colleagues report their findings in an article featured on the cover of the Sept. 15, 2010 issue of the journal Virology, now available online. In 2004, other researchers reported that TRIM5a protects rhesus monkeys from HIV. The TRIM5a protein first latches on to a HIV virus, then other TRIM5a proteins gang up and destroy the virus. Humans also have TRIM5a, but while the human version of TRIM5a protects against some viruses, it does not protect against HIV.
