Detection of XCR1 in CD141⁺and HLA-DR⁺Human Blood Monocytes by Flow Cytometry. CD141⁺and HLA-DR⁺human peripheral blood monocytes were isolated by staining with (A) Mouse Anti-Human HLA-DR Fluorescein-Conjugated Monoclonal Antibody (Catalog # FAB4869F) and Mouse Anti-Human Thrombomodulin/BDCA-3 (CD141) APC-Conjugated Monoclonal Antibody (Catalog # FAB3947A). Isolated cells were then stained with (B) Rabbit Anti-Human XCR1 Monoclonal Antibody (Catalog # MAB8571, filled histogram) or isotype control antibody (Catalog # AB-105-C, open histogram), followed by Phycoerythrin-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # F0110).

Background: XCR1

XCR1, also known as GPR5 and Lymphotactin/SCM-1 (Single Cysteine Motif 1) Receptor, is a 38 kDa member of the G-protein coupled receptor 1 family. It binds XCL1/Lymphotactin/SCM-1 alpha and XCL2/SCM-1 beta. In addition, Human Herpes Virus 8 (HHV8) encodes two viral chemokines vCCL2/vMIP-II and vCCL3/vMIP-III that function as an antagonist and a highly selective agonist, respectively, for XCR1. XCR1 is expressed on neutrophils, CD8⁺ T cells, NK cells, CD4⁺ T cells and B cells. Human XCR1 is a 333 amino acid (aa), 7-transmembrane molecule. It contains a 32 aa N-terminus that lacks glycosylation sites and a 42 aa C-terminal cytoplasmic tail. Over the extracellular regions used for immunization, human XCR1 shares 62%, 54% and 64% aa identity with canine, mouse and porcine XCR1, respectively.
