Mast cells have Toll-like receptors and interact with dendritic cells, B cells, and T cells to help mediate adaptive immune functions.Mast cells express MHC class II molecules and can participate in antigen presentation; however, the mast cell's role in antigen presentation is not very well understood.Mast cells can consume and kill gram-negative bacteria (e.g., salmonella), and process their antigens.They specialize in processing the fimbrial proteins on the surface of bacteria, which are involved in adhesion to tissues.In addition to these functions, mast cells produce cytokines that induce an inflammatory response.This is a vital part of the destruction of microbes because the cytokines attract more phagocytes to the site of infection.
