A Second CD4-Binding Region ofHIV-1 gp120 Critical for Viral Infectivity: New Methods for Treatment and Vaccine Development

Description of Technology: It is believed that immunization with an effective immunogen based on the HIV-1 envelope glycoprotein can elicit a neutralizing antibody response, which may be protective against HIV-1 infection. NIAID researchers have discovered a new critical component of the CD4-binding site in gp120, named CD4-BS2, which is exclusively formed in the trimeric envelope conformation. It was further found that this newly recognized region is critical for the progression of the fusogenic mechanism that leads to HIV-1 entry and infection of the cells. This discovery may lead to new methods of treatment, for treating HIV-1, as well as to the production of new vaccine immunogens.

This technology is available for licensing for commercial development in accordance with 35 U.S.C. 209 and 37 CFR part 404, as well as for further development and evaluation under a research collaboration.

Potential Commercial Applications: New target for HIV therapeutic and vaccine development.

Competitive Advantages: A new molecular target discovered in this invention may facilitate the development of next-generation HIV therapeutics and vaccines.

Development Stage: Proof-of-concept studies demonstrate that CD4 binding to CD4-BD2 is critical for triggering gp120 conformational changes that enable coreceptor binding and HIV-1 infectivity. Animal studies are ongoing.
