摘要
Neutralizing antibodies (Nabs) are thought to play an important role in prevention and control of HIV-1 infection and should be targeted by an AIDS vaccine. It is critical to understand how HIV-1 induces Nabs by analyzing viral sequences in both tested 病毒es and sera. Neutralization susceptibility to antibodies in autologous and heterologous plasma was determined for multiple Envs (3-6) from each of 15 subtype-C-infected individuals. Heterologous neutralization was divided into two distinct groups: plasma with strong, cross-reactive neutralization (n=9) and plasma with weak neutralization (n=6). Plasma with cross-reactive heterologous Nabs also more potently neutralized contemporaneous autologous 病毒es. Analysis of Env sequences in plasma from both groups revealed a three-amino-acid substitu
