Background	DC-SIGN (“DC Specific, ICAM-3 Grabbing, Nonintegrin”) / CD209 is a type II membrane protein with an external mannose-binding C-type lectin domain. DC-SIGN is expressed by immature and mature dendritic cells (DC). In the skin, DC-SIGN+ DC are exclusively located in the dermis. DC-SIGN binds to ICAM-3 on resting T cells, establishing DC-T cell contact and adaptive immunity. DC-SIGN is a high affinity receptor for HIV gp120, allowing HIV capture and transmission to CD4+ T cells. In addition to HIV, DC-SIGN is a receptor for a number of other viral and cellular pathogens including Mycobacterium tuberculosis, and is a major player in microbial evasion of the immune system.

Synonyms	DCSIGN1, DCSIGN, DC-SIGN1, CLEC4L, Dendritic Cell Marker
Note	Protocol: HIV-gp120 blocking protocol: HeLa and HeLa-DC-SIGN were incubated with 100μl of DC-SIGN antibody (3-10μg/ml) during 30’ at 37°C. Cells were washedwith culture medium during 5’ at 1600 rpm, and stained with biotin-gp120 (5μg/ml) during 1h at 37°C (Immunodiagnostics). Cells were washed with culture medium during 5’ at 1600 rpm followed by staining with PE-conjugated streptavidin (dilution 1/20) during 30’ at 4°C (Becton Dickinson). After a last washing, cells were analyzed by flow cytometry.
