Emerging bacteria species and functional pathways involved in the protection of IBD. In addition to the well-known mechanisms, emerging bacteria species and functional molecules/pathways identified recently possess the potential to protect hosts from IBD. The mode of action includes the bacterial own component interacting with receptors on IECs and immune cells with the participation of Treg, DC and macrophage. Toll-like receptor 4 (TLR4), Retinoic acid (RA), NLR family pyrin domain containing 3 (NLRP3), Dendritic cell (DC), α7 nicotinic acetylcholine receptor (α7nAChR).
