  • Description

  • Flagellin FliC is a recombinant flagellin protein encoded by the fliC gene from Salmonella typhimurium. Bacterial flagellin, a TLR5 ligand, is a potent T-cell antigen and has potential as a vaccine adjuvant. Unlike other TLR agonists, flagellin tends to produce mixed Th1 and Th2 responses rather than strongly Th1 responses. It has been demonstrated that flagellin can act as a potent adjuvant in flu vaccines. Furthermore, flagellin can also signal through the NLRC4 inflammasome, although it is not known whether this pathway contributes to the adjuvant activity of flagellin.
    Flagellin from Salmonella typhimurium has been tested in animal models. Experimental results in mice demonstrated that an intraperitoneal injection of flagellin can induce cytokine production and boost intestinal innate immune defense.
