CXCR
CXC chemokine receptors (CXCRs) are seven-transmembrane chemokine receptors that regulate immune-system development and leukocyte trafficking through chemokine-directed cell migration[1]. Mechanistically, CXCR signaling connects ligand recognition to immune-cell positioning, with CXCL8-CXCR1/CXCR2 driving neutrophil chemotaxis during infection and tissue injury[2]. In disease and experimental models, CXCR4 binds CXCL12/SDF-1, supports chemotaxis and calcium signaling, and functions as the HIV-1 entry cofactor LESTR/fusin[3]. Compared with related isoforms, CXCR3-A and CXCR3-B show divergent activities: CXCR3-B mediates endothelial growth inhibition induced by CXCL9, CXCL10, CXCL11, and CXCL4[4]. CXCR5 differs functionally by mediating selective B-lymphocyte attraction through BCA-1/CXCL13, linking this receptor to lymphoid-tissue B-cell trafficking[5]. For experimental applications, plerixafor/AMD3100 provides a validated CXCR4 antagonist tool that rapidly mobilizes CD34⁺ hematopoietic cells in healthy volunteers[6].
