描述 | Through binding with CC- and CXC-chemokines, CCR and CXCR, the subsets of the chemokine receptor family can trigger an intracellular signal transduction cascade, thus mediating the recruitment of immune cells to the in£ammation or infection sites and implicated in several immuno-related disease states, organogenesis, angiogenesis and tumor growth and metastasis. AMD3100 is a selective antagonist of CXCR4 with IC50 values ranging in 0.01-0.13μg/ml for antagonizing SDF-1, but not itself, activated calcium flux in different cells tested, including CXCR4-transfected U87 and CD4 cells, freshly isolated PBMCs, SupT1, THP-1, HSB-2, Molt-4 and L1210 cells. The inhibitory effect of AMD3100 against the induced endocytosis of CXCR4 is selectively SDF-1-dependent but not phorbol ester. Pre-incubated with AMD3100 at concentration of 0.04, 0.2, 1, 5 and 25μg/ml could dose-dependently inhibit the SDF-1-induced (200 ng/ml) chemotaxis of human PBMCs[1]. In vivo study showed that intraperitoneal injection with 5mg/kg AMD3100 can alter the potential of mesenchymal stem cells mobilization induced by different growth factors, including IGF-1, SCF, PDGF and VEGF, in mice, which may be mediated through Akt/PI3K, MEK1/2-Erk1/2 and smad2/3 as key signaling pathways[2]. | ||
