The innate immune system of mammals has been forged by coevolution with microbes in response to the double constraint of preserving a symbiotic interaction with commensal flora and eliminating intrusion of those commensals or invasion by pathogens. Thus, a 'sensing' network, accompanied by or lacking inflammatory responses, is controlled by elaborate mechanisms of regulation that maintain balance in the basal state. A growing number of non-Toll-like innate immune receptors is recognized as part of this surveillance network.
