| 描述 | CD303 (BDCA-2) is a type II c-type lectin specifically expressed by human PDC. CD303 has a putative mannose specificity due to an EPN motif in its C-terminal, extracellular domain. CD303 signaling induces tyrosine phosphorylation and Src kinase dependent calcium influx. CD303 is a specific surface marker of human pDCs, centrally involved in antigen presentation and immune tolerance. Monoclonal antibodies directed against CD303 have been studied in preclinical models and have achieved disease control in patients with cutaneous lupus erythematosus. | ||
