Dopamine 是在脑黑质，脑腹侧被盖区和下丘脑中产生的一种儿茶酚胺类神经递质，在大脑和身体中起着重要作用。Dopamine 通过 D2 多巴胺受体 (D2 dopamine receptor) 来诱导 VEGFR2 的内吞作用，这对于促进血管生成是至关重要的。

Background:

Dopamine is a catecholamine neurotransmitter that is produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain. Dopamine plays several important roles in the brain and body[1]. Dopamine acts through D2 dopamine receptors to induce endocytosis of VEGFR2, which is critical for promoting angiogenesis[1].

Vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) strongly stimulates human umbilical vein endothelial cells (HUVECs) proliferation. The stimulatory effect of VPF/VEGF is abrogated by Dopamine (1 µM; 24hours)[2].

Dopamine (50 mg/kg; i.p. injection; days 1-7) strongly and selectively inhibits the vascular permeabilizing and angiogenic activities of VPF/VEGF[2].
