Research Summary

With the inability of available HIV-1 vaccines to achieve protection, there is a clear need for the identification of novel vaccine targets and approaches. A key focus of the work of Dr. Pinter's lab is understanding the basis for the inability of the immune system to control HIV, and identification of new targets and vaccine approaches that can overcome these limitations. The role of conformational masking towards neutralization resistance is being analyzed in detail, with a focus on specific determinants that contribute to masking and identification of mutations that can reverse this effect.

A second approach is based on the identification of antibodies in sera of HIV-infected subjects that possess broad and potent neutralizing activities. The nature of the targets of these antibodies is not known, but it is clear these do not represent standard well-characterized epitopes. In a number of cases, there is evidence that these may involve quaternary targets that are dependent on the native trimeric Env structure. Immune sera are being screened for such activities, and the antibodies and epitopes that are involved are being characterized. Monoclonal antibodies possessing similar activities are being cloned from B cells of infected humans and immunized macaques, and the activities and specificities of these antibodies are being defined. The information derived from these studies is being used to design immunogens and vaccination strategies for inducing such broadly protective antibody responses.
