Distinct antibody profiles in HLA-B(∗)57(+), HLA-B(∗)57(−) HIV controllers and chronic progressors
Spontaneous control of HIV replication without treatment in HIV-1 controllers (HICs) was associated with the development of an efficient T-cell response. In addition, increasing data suggest that the humoral response participates in viral clearance. DESIGN: In-depth characterization of Ab response i...

description | Spontaneous control of HIV replication without treatment in HIV-1 controllers (HICs) was associated with the development of an efficient T-cell response. In addition, increasing data suggest that the humoral response participates in viral clearance. DESIGN: In-depth characterization of Ab response in HICs may help to define new parameters associated with this control. METHODS: We assessed the levels of total and HIV-specific IgA and IgG subtypes induction and their functional potencies – that is, neutralization, phagocytosis, antibody-dependent cellular cytotoxicity (ADCC), according to the individual's major histocompatibility complex class I (HLA)-B∗57 status, and compared it with nontreated chronic progressors. RESULTS: We found that despite an undetectable viral load, HICs displayed HIV-specific IgG levels similar to those of chronic progressors. Interestingly, our compelling multifunctional analysis demonstrates that the functional Ab profile, by itself, allowed to discriminate HLA-B∗57(+) HICs from HLA-B∗57(−) HICs and chronic progressors. CONCLUSION: These results show that HICs display a particular HIV-specific antibody (Ab) profile that may participate in HIV control and emphasize the relevance of multifunctional Ab response analysis in future Ab-driven vaccine studies. |
