NOD like receptors Flashcards
what are NLRs
NOD like receptors are a cytosolic receptor that recognize DAMPs and PAMPs in the cytosol
what is the “NLR”
a structural domain shared by all the receptors
“nucleotide oligomerization domain”
NLRP 3 –>
NLRP -3 + adaptor proteins + caspase-1 (inactive) –> NLRP-3 inflammasome –> caspase-1 active –> Pro-IL 1beta cleaved to IL-1 beta —> IL-1beta secreted –> acute inflammation
autoinflammatory functions
gain of function mutation in NLRP-3
gout
join disease caused by deposition of urate crystals, recognized by NLRP-3 and inflammasome mediated inflammation
NOD-2
NLR specific for bacterial peptides that have entered the cytosol
NOD-2 activates
NF-kB transcription factor
inflammatory bowel disease
associated with polymorphisms of nod-2
