血管紧张素Ⅱ2型受体(angiotensinⅡtype 2 receptor,AT2受体)是近年研究的热点,其主要发挥拮抗血管紧张素Ⅱ1型受体的作用,起着舒张血管,降低血压,调节水盐代谢,抑制细胞增殖,促进细胞分化、凋亡等作用,这些作用提示其对心脑血管系统生长发育、功能的平衡稳定以及疾病的发生发展过程都有重要的意义。 Angiotensin Ⅱ type 2 receptor (AT2 receptor) is a hot research topic in recent years. It mainly plays the role of antagonizing angiotensin Ⅱ type 1 receptor, playing the role of vasodilation, lowering blood pressure, regulating water and salt metabolism, inhibiting Cell proliferation, promote cell differentiation, apoptosis, etc. These effects suggest that it has important significance for the growth and development of cardiovascular and cerebrovascular systems, the balance of functions and the development and progression of diseases.
