Development of Immune-Modulated HIV Vaccines

Project: Research project

Project Details

Description

A vaccine against HIV is urgently needed. The development of such vaccine represents an unprecedented
challenge. The tremendous genetic diversity of HIV, for example, imposes a major obstacle for vaccine
development. Furthermore, HIV infects activated CD4 T cells that are generated following vaccination or
infection, suggesting that HIV feeds from the immune response that it elicits. Therefore, we propose that a
viable vaccine strategy should minimize the induction of immune responses that fuel HIV and maximize
immune responses that control HIV. We first would like to assess a possible detrimental role for virus-specific
CD4 T cell responses and determine whether the immune dysregulation that is observed in AIDS patients has
mechanistic overlaps with that observed in our model of LCMV infection in mice. We would also like to develop
novel vaccine regimens that abrogate the activation of CD4 T cell responses and generate high antibody and
CD8 T cell responses at sites where HIV replicates.
