X-linked Biological Response to HIV Sensing: the ANRS EP 53 Study

Sponsor: ANRS, Emerging Infectious Diseases

Summary

Short title : X-linked biological response to HIV sensing: the ANRS EP 53 study. Main outcome : To demonstrate that HIV-infected women carry the TLR7 c.32A\>T SNP at a higher frequency than uninfected women, arguing in favor of a role of impaired production of IFN-alpha by pDCs in the risk of becoming infected by HIV-1. Secondary outcome : To directly demonstrate at a single cell level that the TLR7 c.32A\>T SNP is responsible for a reduce production of IFN-alpha by pDCs after activation of TLR7 by HIV-1 RNA. Short abstract (public dissemination) : Male and female display some differences in how their immune system responds to pathogens. This could be related to hormonal or genetic factors located on the X chromosome. This project aims at characterizing X-linked factors that can influence the innate immune response to HIV-1.
