WebThe conserved CD4 binding site (CD4bs) on HIV-1 gp120 is a major target for vaccines. It is a priority to determine sites and structures within the CD4bs that are important for inclusion in vaccines. WebPrevious analyses of HIV-1 surface glycoprotein indicate that both the V1/V2 region and the interaction of gp120 with CD4 influence the accessibility of the V3 region on gp120. In this study we investigated the accessibility of the V3 region of HIV-2 recombinant gp125 proteins using V3-specific mAbs (7C8 and 3C4) and analyzed the binding kinetics of soluble CD4 …

WebDescribe the steps that occur during the binding of the virus to the host cell. Binding of gp120 to CD4 induces a conformational change that allows gp120 to bind to the co ‐ receptor. gp41 undergoes a conformational change and inserts into the host cell membrane. WebMar 30, 2024 · Effects of CD4 or CD4bs MAbs on inducing the MAb 17b epitope, assessed by SPR. YU2 core gp120 was flowed over anti-Fc antibody-captured IgG 17b in the absence or presence of a 10-fold molar excess of 2-domain CD4 or Fabs of CD4bs MAbs. The sensorgrams in black and red represent gp120 alone and gp120 with ligands, … dxo photolab watermark
