Stopping HIV with an artificial protein | Science/AAAS | News

For 30 years, researchers have struggled to determine which immune responses best foil HIV, information that has guided the design of AIDS vaccines and other prevention approaches. Now, a research team has shown that a lab-made molecule that mimics an antibody from our immune system may have more protective power than anything the body produces, keeping four monkeys free of HIV infection despite injection of large doses of the virus. Stopping HIV with an artificial protein | Science/AAAS | News.An aerial view of HIV’s surface proteins (blobs) shows how eCD4-Ig can bind to the virus and “neutralize” it.
