Immunopharmacology Comments
XCR1 is one of more than 20 distinct chemokine receptors expressed in human leukocytes. Chemokines primarily act to promote leukocyte chemotaxis to sites of inflammation. XCR1 is expressed by a subset of dendritic cells [8] and along with its ligand 3647 (lymphotactin), is important for dendritic-cell-mediated cytotoxic immune responses and for the induction of self-tolerance and generation of Treg cells in the thymus.
Cell Type Associations
Immuno Cell Type:  Dendritic cells
Cell Ontology Term:   CD141-positive myeloid dendritic cell (CL:0002394)
Comment:  Human XCR1 is expressed exclusively in CD141+ (BDCA3+) DCs, and in mouse expression is restricted to CD8+ DCs which are phenotypically similar to the human cells. XCR1 is NOT expressed in T cells, B cells, NK cells, granulocytes, monocytes, or other DC subsets.
