RECEPTORS OF THE IMMUNE SYSTEM, PHAGOCYTIC CELLS, AND TOLERANCE  Receptors of the innate immune system mediate a number of different functions.  Many are phagocytic receptors that stimulate ingestion of the pathogens they recognize.  Some are chemotactic receptors, such as the f-Met-Leu-Phe receptor, which binds the N-formylated peptides produced by bacteria, and guides neutrophils to sites of infection.  A third function is to induce effector molecules, that cont...
