UCLA AIDS Institute researchers find a peptide that encourages HIV infection

es, also known as defensins ?alpha, beta and theta, Lehrer said. Humans have only alpha and beta; monkeys have all three.

"Here's a peptide whose normal structure allows it to protect against viruses, yet if you make the same peptide and place its amino acids in a reverse order, that lets the virus in," Lehrer said. "We would like to learn why it happens, but at the moment there's no explanation for this paradoxical result."

Still, the findings seem to show promise in gene therapy.
