Recombinant Human DC-SIGN protein (Fc Chimera)

기능

Pathogen-recognition receptor expressed on the surface of immature dendritic cells (DCs) and involved in initiation of primary immune response. Thought to mediate the endocytosis of pathogens which are subsequently degraded in lysosomal compartments. The receptor returns to the cell membrane surface and the pathogen-derived antigens are presented to resting T-cells via MHC class II proteins to initiate the adaptive immune response.. On dendritic cells (DCs) it is a high affinity receptor for ICAM2 and ICAM3 by binding to mannose-like carbohydrates (PubMed : 10721994, PubMed : 10721995, PubMed : 11017109, PubMed : 12574325). May act as a DC rolling receptor that mediates transendothelial migration of DC presursors from blood to tissues by binding endothelial ICAM2 (PubMed : 11017109). Forms a first contact between DC and resting T cell, througth ICAM3 binding, facilitating the downstream DC-T cell clustering process and DC-induced proliferation of resting T Cells (PubMed : 10721994, PubMed : 10721995)..

(Microbial infection) Acts as an attachment receptor for Lassa virus (PubMed : 23966408). Acts as an attachment receptor for Marburg virusn.. (Microbial infection) Acts as an attachment receptor for Respiratory syncytial virus.. (Microbial infection) Acts as an attachment receptor for Rift valley fever virus and uukuniemi virus.. (Microbial infection) Acts as an attachment receptor for West-nile virus.. (Microbial infection) Probably recognizes in a calcium-dependent manner high mannose N-linked oligosaccharides in a variety of bacterial pathogen antigens, including Leishmania pifanoi LPG, Lewis-x antigen in Helicobacter pylori LPS, mannose in Klebsiella pneumonae LPS, di-mannose and tri-mannose in Mycobacterium tuberculosis ManLAM and Lewis-x antigen in Schistosoma mansoni SEA (PubMed : 16379498). Recognition of M.tuberculosis by dendritic cells occurs partially via this molecule (PubMed : 16092920, PubMed : 21203928).
