HIV hijacks surface molecule to invade cell

Researchers at NIH have discovered that HIV uses a protein on the cell surface to invade cells. By blocking this step, they found it prevents HIV genetic material from entering cells. The study could lead to the development of new drugs to prevent HIV infection by targeting the transfer of phosphatidylserine.
