IP-10/CRG-2/CXCL10 Protein, Human

MCE 国际站：IP-10/CRG-2/CXCL10 Protein, Human

CXCL10，又称干扰素 γ 诱导蛋白10 kDa (IP-10)，是属于 CXC 趋化因子家族的细胞因子。CXCL10 通过与 CXCR3 结合发挥其生物学作用。CXCL10 是一种多效性分子，能够发挥强大的生物学功能，包括促进 CXCR3+ 细胞的趋化活性、诱导细胞凋亡、调节细胞生长和增殖以及在感染性和炎症性疾病和癌症中的血管生成。IP-10/CRG-2/CXCL10 Protein, Mouse 在大肠杆菌中表达产生，由 77 个氨基酸(M22-P98) 组成。

Synonyms: rHuIP-10/CXCL10; C-X-C motif chemokine 10; Gamma-IP10; Mob-1

Species: Human

Source: E. coli

Biological Activity: The ED₅₀ is <0.2 μg/mL as measured by HUVEC cells, corresponding to a specific activity of >5.0 × 10³ units/mg.

研究背景：CXCL10 is a pro-inflammatory chemokine secreted by a wide spectrum of cells. CXCL10 activates T lymphocytes (Th1), NK cells, macrophages, dendritic and B cells. Alterations in CXCL10 expression levels have been associated with inflammatory diseases including infectious diseases, angiogenesis, immune dysfunction and tumor development.
Mature human CXCL10 shares 68% amino acid sequence identity with mouse and rat CXCL10.
Human CXCL10 gene, is initially isolated in 1985 by Luster while treating a lymphoma cell line (U937) with recombinant IFN-γ. CXCL10 cDNA has an open reading frame of 1173-bp containing 4 exons and encoding a protein of 98-amino acids. The primary translational product of the CXCL10 gene is a 12 kDa protein containing two internal disulfide cross bridges. CXCL10 exerts its biological effects by binding to CXCR3, a seven trans-membrane-spanning G protein-coupled receptor in a paracrine or autocrine fashion, which is predominantly expressed on activated T, B lymphocyte, natural killer (NK), dendritic and macrophage cells. CXCL10 induction depends predominantly on the carboxyl-terminal region of CXCR3, which is essential for CXCR3 internalization, chemotaxis and calcium mobilization induced by the CXCL10 ligand. The powerful chemotactic action of CXCL10 on activated lymphocytes allows it to modulate both innate and adaptive immunity, inducing tissue damage and modulating tumor formation.
  CXCL10 is a pleiotropic molecule capable of exerting potent biological functions, including promoting the chemotactic activity of CXCR3+ cells, inducing apoptosis, regulating cell growth and proliferation as well as angiogenesis in infectious and inflammatory diseases and cancer. ELR-negative CXCL10 is an angiostatic chemokine, which inhibits angiogenesis. Abnormal levels of CXCL10 have been observed in body fluids of individuals infected with viruses, bacteria, fungi and parasites.
