Abstract

Background The long-term goal for an efficacious HIV vaccine is to provide sterilizing protection from HIV infection. Thus far, this scenario has only been achieved experimentally using live-attenuated SIV vaccines. As such, great interest lies in identifying correlates of protection from a successful host response to pathogenic SIV. To this end, we have used a global genomics approach, tissue analysis, and explant cultures to identify immune complex (IC) signaling as an important component of a protective host response in the female reproductive tract (FRT) of animals vaccinated with the live-attenuated virus known as SIV mac239 ΔNef.

Highlights

  • The long-term goal for an efficacious HIV vaccine is to provide sterilizing protection from HIV infection

  • Immune complexes can dampen inflammatory signaling at the mucosal surface during protective SIV vaccination

  • Great interest lies in identifying correlates of protection from a successful host response to pathogenic SIV
