A Small Molecule That Blocks Male-to-Female Sexual Transmission of HIV

Recent evidence suggests that HIV infection may be drastically enhanced when a specific protein found in human semen is present in fibril form. David Eisenberg of UCLA in the U.S. will design and test a small peptide that can effectively block formation of fibrils on this protein. If successful, the therapy could be administered via spray or liquid drops to inhibit transmission of HIV.
