NOD-like receptor
NOD-like receptors (NLRs, nucleotide-binding leucine-rich repeat receptors) are cytosolic mammalian pattern-recognition receptors with NOD/NACHT and LRR domains that sense intracellular PAMPs and DAMPs, activate NF-κB, MAPK, and inflammasome pathways, and drive IL-1β release and pyroptosis; NOD2 variants link to Crohn's disease.
NOD1
NOD1 (NLRC1, CARD4) is a human cytosolic NLR pattern-recognition receptor gene on 7p14.3 that senses DAP-type bacterial peptidoglycan muropeptides and activates NF-κB and MAPK via RIPK2.
NOD2
NOD2 (CARD15, IBD1) is a cytosolic NLR pattern-recognition receptor sensing bacterial muramyl dipeptide and signaling via RIPK2 to NF-κB; loss-of-function variants predispose to Crohn's disease, gain-of-function variants to Blau syndrome.

A nodal chain semimetal, also called a nodal chain metal, is a topological semimetal whose conduction and valence bands touch along a chain of interconnected loops in momentum space.
Nodal marginal zone lymphoma
Nodal marginal zone B-cell lymphoma (NMZL) is a rare indolent B-cell lymphoma of the lymph nodes, one of three marginal zone lymphoma subtypes, distinguished from splenic and MALT lymphoma by PTPRD mutations and purely nodal dissemination.
Nodal precession
Nodal precession, also known as nodal regression, is the gradual rotation of an orbit's line of nodes due to gravitational perturbations, chiefly Earth's equatorial bulge. It enables sun-synchronous orbits.
Nodal radiotherapy
Nodal radiotherapy is the irradiation of regional lymph nodes in cancers such as lymphoma, prostate, and breast, ranging from elective whole-basin coverage to stereotactic treatment of single nodes.
