Dectin-2 is a C-type lectin expressed by dendritic cells, macrophages and inflammatory monocytes. It is a type II membrane receptor, with a short cytoplasmic tail, and a C-terminal C-type lectin domain. Dectin-2 is a receptor with specificity for high mannose structures and mediates cytokine production from DC and other antigen presenting cells. Though, Dectin-2 has no obvious signaling motifs attached to CP tail, reports indicate that Dectin-2 employs FcRg for internalization and to activate NF-kappaB pathway for cytokine production. Though it shares only 20-25% of homology with Dectin-1, it functions similarly as pattern recognition receptor (PRR) for fungal infections, to activate both innate (Syk-CARD9 innate signaling pathway) and adaptive immune responses (by activation of DC) to fungal infections. Thus Dectin-2 is a connector molecule of both innate and adaptive immunity functioning at DC level.
