A Second CD4-binding Region of HIV-1 gp120 Critical for Viral Infectivity: New Methods for Treatment and Vaccine Development
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.
