β2肾上腺素能受体(β2-AR)是交感神经系统的重要组成部分,对血压的短期和长期调节均有重要的影响。如果决定β2-AR性状的基因发生突变,可以导致原发性高血压(EH)。因此,关于β2-AR基因多态性与EH相关性的研究倍受关注。 β2-adrenoceptor (β2-AR) is an important part of the sympathetic nervous system and has important implications for the short-term and long-term regulation of blood pressure. If the gene that determines the β2-AR trait is mutated, it can cause essential hypertension (EH). Therefore, the research on the relationship between β2-AR gene polymorphism and EH has drawn much attention.
