Broadly neutralizing anti-HIV antibodies
Breitneutralisierende anti-HIV antibody ( English broadly neutralizing anti-HIV antibodies , bNAbs) are against several HIV effective strains neutralizing antibodies .
properties
Most neutralizing antibodies are specific for a strain in their neutralizing effect. Broadly neutralizing antibodies bind to conserved areas on the surface of proteins on the virus surface. The generation of broadly neutralizing anti-HIV antibodies is a goal of HIV vaccine design . Broadly neutralizing anti-HIV antibodies are listed in the online databases bNAber and LANL Antibody database . The neutralization effect is dependent both on the binding of the bNAb to viral proteins and on the efficient binding of the bNAb to the Fc receptor . An efficient binding to the FcRn ( isoform of the Fc receptor), which occurs vaginally and rectally, can intensify the neutralization at the entry point of HIV.
Broadly neutralizing anti-HIV antibodies can be subdivided according to their binding site. B. to the part of the GP41 ( membrane-proximal external region , MPER) adjoining the transmembrane domain , to the peptidoglycan layer of the GP120, to the binding site of GP120 for the cellular receptor CD4 or to the variable regions of the GP120 (V1–3) respectively.
