Flagellin stimulation of intestinal
WebRadiation-induced acute intestinal toxicity remains a major limitation to the delivery of tumoricidal doses of colorectal irradiation. Recent reports indicate that Toll-like receptor (TLR) agonists TLR4 and TLR5 protect against toxicity due to intestinal irradiation. ... LPS and flagellin drove macrophages toward the anti-inflammatory M2 ... WebMoreover, flagellin stimulation did not induce IFN-β expression in intestinal epithelial cells (Fig. 5F). Thus, it appears that TRIF in TLR5-induced responses may be associated with regulating NFκB and MAPK activation rather than IRF-3 activation and IFN-β expression, and this subsequently mediates TLR5-dependent inflammatory responses.
