COA 产品使用指南 技术支持

Neopterin 是一种 GTP 代谢的免疫系统激活剂,可由活化巨噬细胞产生。Neopterin 具有抗血管炎症和抗动脉粥样硬化的潜力。Neopterin 抑制 NF-κB 磷酸化、促进 PPAR-γ 表达,从而抑制血管内皮细胞炎症反应、减少巨噬细胞泡沫细胞形成,并调节血管平滑肌细胞的迁移和增殖。Neopterin 可用于心血管疾病 (如动脉粥样硬化)、炎症相关疾病及肿瘤免疫监测等领域的研究。

生物活性

Neopterin is an immune system activator metabolized by GTP and can be produced by activated macrophages. Neopterin has the potential to resist vascular inflammation and atherosclerosis. Neopterin inhibits the phosphorylation of NF-κB and promotes the expression of PPAR-γ, thereby suppressing the inflammatory response of vascular endothelial cells, reducing the formation of macrophage foam cells, and regulating the migration and proliferation of vascular smooth muscle cells. Neopterin can be used in research fields such as cardiovascular diseases (such as atherosclerosis), inflammation-related diseases and tumor immunomonitoring[1][2][3][4][5].

Human Endogenous Metabolite

 

体外研究
(In Vitro)

Neopterin (200 nM;4-48 h) 在人主动脉内皮细胞 (HAECs) 和人脐静脉内皮细胞 (HUVECs) 中可抑制细胞增殖、降低 TNF-α 诱导的 MCP-1、ICAM-1、VCAM-1 等炎症因子的 mRNA 和蛋白表达,并减少单核细胞黏附[1]
Neopterin (200 nM;7 d+19 h) 在人单核细胞衍生的巨噬细胞 (HMDMs) 中可抑制氧化低密度脂蛋白 (oxLDL) 诱导的泡沫细胞形成,下调 CD36 表达,上调 ABCA1、ABCG1 及 LXR-α 蛋白水平,促进胆固醇外流[1]
Neopterin (200 nM;24-48 h) 在人主动脉平滑肌细胞 (HASMCs) 中可抑制血管紧张素 II 诱导的细胞迁移和增殖,下调 c-Src/Raf-1/ERK1/2 信号通路,上调纤维连接蛋白、MMP-2 及 TIMP-2 蛋白表达[1]

Cell Viability Assay[1]

Cell Line: Human aortic endothelial cells (HAECs), human umbilical vein endothelial cells (HUVECs), human aortic smooth muscle cells (HASMCs)
Concentration: 5-200 nM
Incubation Time: 48 h
Result: Significantly suppressed proliferation in HAECs and HUVECs in a concentration-dependent manner, with maximal inhibition at 200 nM.
Reduced cell viability, with the most pronounced effect at 200 nM in HASMCs.
体内研究
(In Vivo)

Neopterin (1.2 μmol/kg;腹腔注射;每日 1 次;4 周) 在载脂蛋白 E 缺陷 (Apoe-) 小鼠中可显著减缓主动脉粥样硬化病变发展,减少斑块面积及单核细胞/巨噬细胞、CD8+ T 细胞浸润,降低血管平滑肌细胞含量及血浆 PTX-3 水平[1]
Neopterin (0.4-4.0 mg/kg;静脉注射;单剂量,检测 21 天) 在雄性衰老加速小鼠的衰老相关基质细胞损伤模型中,导致年轻小鼠骨髓红细胞祖细胞 (BFU-E、CFU-E) 数量减少、髓系祖细胞 (CFU-GM) 数量增加。而老年小鼠中红细胞祖细胞减少,且血清促红细胞生成素 (Epo) 浓度未下降[2]

Animal Model: Male C57BL/6 Apoe- mice (27-29 g, 17-21 weeks old) with diet-induced atherosclerosis[1]
Dosage: 1.2 μmol/kg
Administration: Intraperitoneal injection daily for 4 weeks
Result: Aortic atherosclerotic lesion area and cross-sectional plaque size at the aortic root were reduced by 35% and 17%, respectively, compared to vehicle-treated controls.
Immunohistochemistry showed decreased infiltration of monocyte/macrophages (MOMA-2+ cells) and CD8+ T cells in atheromatous plaques.
Vascular smooth muscle cell (α-SMA+) content and expression of pro-inflammatory markers MCP-1 and PTX-3 in plaques were significantly lower in neopterin-treated mice.
Plasma PTX-3 levels, a marker of plaque instability, were reduced by 30% compared to controls.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
