There is significant progress in understanding the structure and function of NLRC5, a member of the nucleotide oligomerization domain-like receptor family. However, in the context of MHC class I gene expression, the functions of NLRC5 in innate and adaptive immune responses beyond the regulation of MHC class I genes remain controversial and unresolved. In particular, the role of NLRC5 in the kidney is unknown. NLRC5 was significantly upregulated in the kidney from mice with renal ischemia/reperfusion injury. NLRC5 deficient mice significantly ameliorated renal injury as evidenced by decreased serum creatinine levels, improved morphological injuries, and reduced inflammatory responses versus wild type mice. Similar protective effects were also observed in cisplatin-induced acute kidney injury. Mechanistically, NLRC5 contributed to renal injury by promoting tubular epithelial cell apoptosis and reducing inflammatory responses were, at least in part, associated with the negative regulation of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1). To determine the relative contribution of NLRC5 expression by parenchymal cells or leukocytes to renal damage during ischemia/reperfusion injury, we generated bone marrow chimeric mice. NLRC5 deficient mice engrafted with wild type hematopoietic cells had significantly lower serum creatinine and less tubular damage than wild type mice reconstituted with NLRC5 deficient bone marrow. This suggests that NLRC5 signaling in renal parenchymal cells plays the dominant role in mediating renal damage. Thus, modulation of the NLRC5-mediated pathway may have important therapeutic implications for patients with acute kidney injury.
