Briefly, the findings in the study by Descours et al. pointing to CD32 as a potential marker of HIV reservoir were: selective induction of CD32 after infection of resting CD4 cells; several hundred-fold enrichment of HIV-DNA in CD4 cells expressing CD32, especially in the very rare CD32bright population; several thousand-fold enrichment of inducible replication-competent virus in CD32+ cells. This evidence concerns the gene FCGR2B and infection.
