Quiescent CD4 T cells in lymphoid tissues are shown to die after HIV-1 infection by caspase-1-mediated pyroptosis, a highly inflammatory form of programmed cell death; caspase 1 inhibitors, which are safe for human use, can rescue the cell death in vitro raising the possibility of new therapeutics targeting the host instead of the virus.
