Popis: | The global rise of antibiotic-resistant strains ofSalmonellahas necessitated the development of alternative therapeutic strategies. Recent studies have shown that targeting host factors may provide an alternative approach for the treatment of intracellular pathogens. Host-directed therapy (HDT) modulates host cellular factors that are essential to support the replication of the intracellular pathogens. In the current study, we identified Gefitinib as a potential host directed therapeutic drug againstSalmonella. Further, using the proteome analysis ofSalmonella-infected macrophages, we identified EGFR, a host factor, promoting intracellular survival ofSalmonella viamTOR-HIF-1α axis. Blocking of EGFR, mTOR or HIF-1α inhibits the intracellular survival ofSalmonellawithin the macrophages and in mice. Global proteo-metabolomics profiling indicated the upregulation of host factors predominantly associated with ATP turn over, glycolysis, urea cycle, which ultimately promote the activation of EGFR-HIF1α signaling upon infection. Importantly, inhibition of EGFR and HIF1α restored both proteomics and metabolomics changes caused bySalmonellainfection. Taken together, this study identifies Gefitinib as a host directed drug that holds potential translational values againstSalmonellainfection and might be useful for the treatment of other intracellular infections. |
