Beta-1,3-glucan from Alcaligenes faecalis; Dectin-1 ligand

Curdlan is a high molecular weight linear polymer consisting of β-(1 -> 3)-linked glucose residues. Curdlan is produced as a water-insoluble polysaccharide by the soil bacterium, Alcaligenes faecalis.

Curdlan is recognized by the membrane bound Dectin-1 receptor leading to the CARD9-dependent activation of NF-κB and MAP kinases [1]. Furthermore, Dectin-1 signaling activates the NFAT transcription factor. Recent data suggest that Curdlan is also recognized by the cytosolic NLRP3 inflammasome complex which cooperates with Dectin-1 resulting in a robust activation of IL-1β–mediated inflammatory response [2].
