EPI-X4 TFA

产品编号 T83763

别名 Endogenous Peptide Inhibitor of CXCR4

EPI-X4是一种源于人血清白蛋白408-423氨基酸的内源性肽段，是趋化因子(C-X-C基序)受体4 (CXCR4)的拮抗剂。在0.8至1,000µM的浓度范围内，EPI-X4能抑制表达CXCR4的HEK293细胞中由趋化因子(C-X-C基序)配体12 (CXCL12)诱发的钙离子动员和受体内化。EPI-X4还能抑制CXCL12诱导的Jurkat T细胞和人类CD34+造血干细胞的迁移。体内实验中，EPI-X4（16µmol/kg）在急性过敏性气道高嗜酸性粒细胞疾病的小鼠模型中减少了Cxcr4依赖的炎症细胞气道浸润。慢性肾脏病患者尿液中EPI-X4的水平增高，并与肾小球滤过率(GFR)成反比。

生物活性

产品描述

EPI-X4, an endogenous peptide fragment of human serum albumin (amino acids 408-423), serves as an antagonist to the chemokine (C-X-C motif) receptor 4 (CXCR4). It effectively prevents calcium mobilization and receptor internalization triggered by chemokine (C-X-C motif) ligand 12 (CXCL12) in HEK293 cells with CXCR4 expression, at concentrations between 0.8 and 1,000 µM. Moreover, EPI-X4 hampers the CXCL12-driven migration of both Jurkat T cells and human CD34+ hematopoietic stem cells. In an acute allergic airway hypereosinophilia mouse model, EPI-X4 intrinsically decreases Cxcr4-dependent inflammatory cell infiltration in airways at a dose of 16 µmol/kg. Additionally, increased urinary EPI-X4 levels, inversely related to glomerular filtration rate (GFR), are observed in chronic kidney disease patients, indicating its potential biomarker role.
