Nucleotide-binding oligomerization domain 2 (NOD2) is one of the most prominent member of the NOD-like receptors protein family that functions as intracellular pattern recognition receptors. Numerous studies have suggested the importance of NOD2 in defensing against microbial infections, regulation of the inflammatory process. It is shown that NOD2 contributes to the pathogenesis of various autoimmune and chronic inflammatory diseases, such as Crohn's disease, rheumatoid arthritis. The aim of this study is to summarize our current understandings of NOD2 function and the role of NOD2 in systemic lupus erythematosus (SLE). The following databases were searched: Pubmed, EMBASE and Web of Science for English-language sources, using the terms "lupus," "systemic lupus erythematosus," ''SLE," "immunity," "inflammatory" and "NOD2." Emerging data evidences that NOD2 has important biological effects in autoimmunity and inflammatory and might take part in the pathogenesis of SLE. Studies exploring the relationship between NOD2 and SLE are very limited. Whether NOD2 could be a potentially valuable therapeutic target for treatment for SLE, more understanding of the mechanism of NOD2 is needed in the future in SLE.
