The activation of caspase-1 by the detection of bacterial products through Nod-like receptors leads to the secretion of mature interleukin-1beta (IL-1beta) and IL-18 and the induction of rapid host cell death (pyroptosis). Here, we report that pyroptosis induced by Salmonella enterica serovar Typhimurium can be positively regulated by prior gamma interferon (IFN-gamma) stimulation of RAW 264.7 cells. This increase in cell death is dependent on both caspase-1 activation and, in part, Salmonella pathogenicity island 1 (SPI-1) expression by Salmonella. Furthermore, the exogenous expression of the IFN-gamma-induced protein guanylate binding protein 5 (GBP-5) is sufficient to induce a heightened susceptibility of RAW 264.7 cells to Salmonella-induced pyroptosis, and the endogenous expression of GBP-5 is important for this phenomenon. RAW 264.7 cells with decreased expression of GBP-5 mRNA (inhibited by short hairpin RNA against GBP-5) release twofold less lactate dehydrogenase (a marker of membrane permeability) upon infection by invasive S. enterica serovar Typhimurium than do infected control cells. Importantly, 3x FLAG-tagged GBP-5 is localized to membrane ruffles, which contact invasive Salmonella, and is found on the membranes of spacious phagosomes containing Salmonella (although it is also found in the cytoplasm and on other cellular membranes), placing 3x FLAG GBP-5 at the interface of secreted SPI-1 effectors and host protein machinery. The regulation of pyroptosis by the IFN-gamma-induced protein GBP-5 may play an important role in the host defense against Salmonella enterica serovar Typhimurium and perhaps other invasive bacterial pathogens."xsd:string |
