The roles of NOD1 and NOD2 in tumorigenesis and development / 中国生化药物杂志

ABSTRACT

Theinnate immunity system of human body has more and more attention for its antibacterial, antiviral, maintainingimmunehemostasis and promoting tissue damage and repair and other physiological functions.As members of NOD-like receptors(NLRs), NOD1 and NOD2 receptors are identified as intracellular pattern recognition receptors(PRRs), can be identified with molecular damage endogenous(damage-associated molecular patterns, DAMPs)and exogenous injury-molecular pathogen associated molecular(pathogen-associated molecular patterns, PAMPs), and initiation of innate and specific immune response, maintain the steady balance of body.Recently, a bunch of evidence have demonstrated that the importance of NOD1 receptor and NOD2 receptor is not limited in field of anti-infection, and the insulin resistance, kidney and liver damage recovery, cardiovascular disease and tumorigenesis are also closely related with these two receptors.So the aim of this article is to interpret the NOD1 and NOD2 general structure and function, and summarize the link between these two PRRs and tumorigenesis and finally make a clue for cancer immunotherapy.
