GRO-beta/CXCL2 Protein, Rat

MCE 国际站：GRO-beta/CXCL2 Protein, Rat

CXCL2，也称为Gro-beta 或 MIP-2，是一种促炎细胞因子，对中性粒细胞具有趋化活性。CXCL2 由活化的单核细胞和中性粒细胞产生并在炎症部位表达。CXCL2 参与许多免疫反应，包括伤口愈合、癌症转移和血管生成。GRO-beta/CXCL2 Protein, Rat 是在大肠杆菌中表达产生的，由 69 个氨基酸组成(A32-N100)。

Synonyms: rRtGRO-β/CXCL2; MIP-2; CINC-3; C-X-C motif chemokine 2

Species: Rat

Source: E. coli

Biological Activity: The EC₅₀ is <10 ng/mL as measured by CHO-K1/Gα15/rCXCR2 cells (human Gα15 and rat CXCR2 stably expressed in CHO-K1 cells).

研究背景：CXCL2 is a chemokine induced by endotoxin and serves as an extremely potent chemo-attractant for neutrophils, acting as a crucial inflammatory mediator. CXCL2 could be produced by multiple, different cell types, including macrophages and cancer cells. CXCL2 is involved in cancer metastasis, angiogenesis, and wound healing.
The amino acid sequence of human CXCL2 protein has low homology between mouse and rat CXCL2 protein.
CXCL2 is 90% identical in amino acid sequence as a related chemokine, CXCL1. The gene for CXCL2 is located on human chromosome 4 in a cluster of other CXC chemokines. CXCL2 binds to the G-protein coupled receptor CXCR2 (IL-8RB) expressed on macrophages, neutrophils, and epithelial cells and its classical function is to act as chemotactic factors attracting neutrophils to sites of injury.
In enterocytes, LPS induces CXCL2 expression and promotes migration of neutrophils in a model of platelet-activating factor induced shock and bowel injury. In acute lung injury, CXCR2 ligands, including CXCL1/2/3, have chemotactic effects for polymorphonuclear leukocytes. CXCL2 could provoke a dose-dependent increase of colorectal tumor cell migration in vitro. Further, according to Bachmeier et al., CXCL-1 and −2 silencing could down-regulate several metastasis-promoting genes and inhibit the metastatic potential of breast cancer cells.
