ABSTRACT
Objective To study the impact of V2 mutations on neutralizing ability of HIV-1-specific neutralizing antibodies. Methods We tested the influence of L175P mutation to the neutralizing ability of V3-specific antibodies by pseudotype virus and the binding affinity of those V3-spesific antibodies to gpl20 monomer by ELISA. Results We found L175P mutation changed the neutralizing ability of V3-specific antibodies. However, L175P mutation showed no effects on the binding affinity of these antibodies to gpl20 monomer. Conclusion Our results revealed the L175P mutation at V2 loop changed the natural trimmer structure of gp120 and enhanced the neutralizing ability of V3-specific antibodies.
