Toll-like receptors represent an ancient pathogen-recognition system. The first pattern recognition receptor (PRR) important in innate immune responses was discovered in the fruit fly Drosophila melanogaster. Stimulation of this receptor, called Toll, induces: The synthesis of prostaglandins and leukotrienes The inflammatory response in Drosophila hemolymph vessels The production of antimicrobial peptides The recruitment of phagocytic cells to the site of infection The activation of Drosophila complement
