Human B Cell Precursor for Broadly Neutralizing Antibody Targeting HIV Envelope Glycoprotein gp120 CD4 Binding Site
- Molecular classification
- B cell, Immune cell, Precursor cell
01
Overview
The human B cell precursor capable of giving rise to broadly neutralizing antibodies (bNAbs) that specifically recognize the CD4 binding site (CD4bs) on the HIV-1 envelope glycoprotein gp120. This site is a critical region on gp120, as it mediates viral attachment to host CD4+ T cells, initiating infection. The development of bNAbs against this conserved epitope is a major focus in HIV vaccine research due to their potential for broad and potent virus neutralization.
02
Mechanism of action
The antibody produced by this B cell precursor binds to the CD4 binding site on HIV gp120, preventing viral entry into host cells.
