Data Sheet

Background: Chemokines and their receptors play a vital role in the regulation of responses in the immune system and in the recruitment of certain lymphocytes. The human chemokine receptor XCR1 is a G-protein-coupled receptor and is associated with the induction of chemotaxis and has been identified in neutrophils, t-lymphocytes, b-lymphocytes. The cytokine receptor XCR1 is a specific marker for human CD141+ DCs and has been reported to play an important role in antigen cross-presentation. There are studies suggesting that agonists targeting XCR1 are effective in producing anti-tumoral T-cell responses. 

Application: Functional assays
