Flow cytometric analysis of Mouse XCR1 expression on collagenase-digested C57BL/6 mouse splenocytes. Collagenase-digested C57BL/6 mouse splenocytes were stained with Alexa Fluor® 647 Rat Anti-Mouse CD8 antibody and either Biotin Mouse IgG Isotype Control (Left panel) or SDT Biotin Mouse Anti- Mouse XCR1 antibody (Right panel) at 5 μl/test followed by Sav-iFluor 488. Data shown was gated on the CD11c+ population. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
XCR1 is a conserved, 37-kDa, seven-transmembrane, G-protein-coupled receptor selectively expressed on CD8α⁺ and CD103⁺ conventional dendritic cells; its only ligand, XCL1, is secreted by activated CD8⁺ T and NK cells to form a feed-forward loop that efficiently recruits antigen-bearing dendritic cells into draining lymph nodes, licenses cross-presentation, and amplifies cytotoxic immune responses against viruses and tumors, while genetic or antibody blockade of XCR1 impairs viral clearance, vaccine efficacy, and checkpoint-blockade-mediated anti-tumor immunity.
