Monkey Protein Blocks HIV. The assumption among many has long been that HIV jumped to humans from other primates. Yet researchers have had a hell of a time getting HIV to infect other primates for treatment testing.
Now scientists have figured out why: old world monkeys have a built-in AIDS blocker: a protein that prevents HIV from shedding its shell and infecting cells with its DNA. Now researchers are focusing on ways to transfer this protein to AIDS patients through gene therapy, or modifying a similar protein already present in humans.[ from Scientific American]
