RT @NatRevImmunol: CARD8 kills CD4+ T cells in response to HIV entry

@CellCellPress According to this paradigm, the progressive CD4+ T cell depletion that characterizes pathogenic infections and predominantly involves cells that are not experiencing productive viral infection is due to CARD8 inflammasome activation, which follows virus entry into CD4+ T cells.

@CellCellPress In conclusion, the current study defines a paradigm to explain the marked differences observed in the clinical outcomes of primate lentiviral infections between pathogenic hosts versus non-pathogenic natural hosts.

@CellCellPress Next, we showed that HIV protease encapsulated in viral particles is detected by CARD8 during viral entry, which leads to rapid CD4+ T-cell death. In contrast, CD4+T cells from the ‘‘natural’’ hosts are resistant to cell death when exposed to SIV particles.

@CellCellPress Previously we reported that the CARD8 inflammasome detects HIV protease activity. Here, we found that CARD8 is present in most vertebrates and is functionally conserved in most primates. Interestingly, the ‘‘natural’’ hosts of SIV have acquired loss-of-function mutations in CARD8.

@CellCellPress In contrast, SIV infection of ‘‘natural’’ hosts such as sooty mangabeys and green monkeys does not cause CD4+ T-cell depletion and AIDS despite high-level viremia.

@CellCellPress While CD4+ T cell depletion is key to disease progression in people living with HIV and SIV-infected macaques, the mechanisms underlying this depletion remain incompletely understood, with most cell death involving uninfected cells.

Excited to share our latest work on the CARD8 #inflammasome in #HIV/SIV pathogenesis and disease progression @CellCellPress Our study suggests that CARD8 drives CD4+ T cell depletion during.HIV infection.
