CD209 Mouse anti-Human, Unlabeled, Clone: DCN46, BD

Description

• The DCN46 antibody specifically binds to dendritic cell-specific ICAM-3 grabbing nonintegrin (DC-SIGN or CD209), a type-II membrane protein of approximately 44 kDa with a mannose-binding C-type lectin domain
• It is highly expressed on dendritic cells in mucosal tissues
• Its sequence is identical to the HIV-1 envelope gp120-binding C-type lectin, and reports suggest that DC-SIGN binds to HIV-1 gp120 and effectively transmits infectious HIV-1 to resting T lymphocytes expressing CD4 and chemokine receptors
• The C-type lectin domain of DC-SIGN is also capable of binding other pathogenic viruses, bacteria, and parasites
• Reports also suggest that DC-SIGN enables the highly efficient migration of dendritic cells from blood into the tissues
• It can interact with ICAM-2, which has a similar sequence as ICAM-3, and is abundantly expressed on vascular and lymphoid endothelium
• Thus, DC-SIGN mediates dendritic cells rolling and transendothelial migration, and its interaction with ICAM-2 is essential to specific migratory functions of dendritic cells.
