Abstract
Most micro-organisms that are encountered daily by a healthy individual are detected initially by defense mechanisms that are not antigen-specific, a response that is mediated by the innate immune system. In contrast to the adaptive immunity, where specific antigen receptors are generated by somatic hypermutation and selection, the innate immune systems uses germline encoded proteins that recognize specific patterns shared by groups of pathogens, but not the host. These receptors are called “pattern recognition receptors” (“PRRs”) and recognize largely invariant “pathogen-associated molecular patterns” (“PAMPs”), as for example lipopolysaccharides of bacteria or double-stranded RNA of viruses [1]. This review will focus on the toll-like receptor (TLR) family, a class of pattern recognition receptors of major importance [2].
