NOD2 (nucleotide-binding oligomerization domain-containing protein 2) is an intracellular pattern recognition receptor critical to innate immunity and inflammatory responses. Belonging to the NOD-like receptor (NLR) family, it detects conserved microbial components, particularly muramyl dipeptide (MDP), a peptidoglycan fragment found in bacterial cell walls. Upon activation, NOD2 initiates signaling cascades (e.g., NF-κB, MAPK pathways) to trigger pro-inflammatory cytokine production and antimicrobial defenses. It also regulates autophagy and maintains gut microbiota homeostasis through interactions with Paneth cells.
Genetic mutations in NOD2 (e.g., SNPs like R702W, G908R, and L1007fsinsC) are strongly associated with autoimmune and chronic inflammatory diseases. Loss-of-function variants impair bacterial sensing, contributing to Crohn's disease pathogenesis, while gain-of-function mutations link to Blau syndrome and early-onset sarcoidosis. These connections have driven extensive research into NOD2's role in immune regulation and disease mechanisms.
Recombinant NOD2 proteins, produced via bacterial, insect, or mammalian expression systems, are essential tools for structural studies (e.g., ligand-binding domains), in vitro interaction assays, and drug discovery. They enable researchers to dissect signaling pathways, validate genetic mutations, and screen therapeutic compounds targeting NOD2 dysregulation. Recent studies also explore engineered NOD2 variants for immunotherapy and vaccine adjuvants. Despite challenges in maintaining proper post-translational modifications during recombinant production, these proteins remain pivotal in advancing diagnostics and treatments for NOD2-related disorders. Current research focuses on modulating NOD2 activity to balance immune responses in inflammatory bowel diseases, cancer, and infectious conditions.
