Interaction among Toll-like recept ro s and other pattern recogni tion receptors in innate immune / 药学实践杂志

Toll-like receptors (TLRs) are germline-encoded pattern recognition receptors (PRRs) that play a central role in host cell recognition and responses to microbial pathogens .TLRs-mediated recognition of components derived from a wide range of pathogens and their role in the subsequent initiation of innate immune responses is widely accepted ,besides, the recent discovery of non-TLR PRRs, such as C-type lectin receptors, NOD-like receptors, and RIG-I-like receptors, suggests that many aspects of innate immunity are more sophisticated and complicated .In this review, we focused on the role cooperated by TLRs in mounting protective im-mune responses against infection and their crosstalk with other PRRs with respect to pathogen recognition .
