肾上腺皮质球状带细胞的电兴奋性与醛固酮分泌:离子通道的作用OACSTPCD
Electrical excitability and aldosterone secretion in the zona glomerulosa cells:the role of ion channels
醛固酮是肾上腺皮质球状带(ZG)细胞产生的类固醇类激素,对体液电解质平衡和血压稳定起着关键调控作用.醛固酮生成是一个钙离子依赖性的过程,离子通道在这一过程中扮演着关键角色.临床上发现的原发性醛固酮增多症大多与离子通道的突变有关.最近ZG细胞独特的rosette结构与其电兴奋性的关系引起了更多研究兴趣.阐明rosette与ZG细胞电兴奋性以及醛固酮分泌之间的关系,有助于更深入地了解调节醛固酮分泌的机制,为原发性醛固酮增多症的发病机制提供新见解.
Aldosterone is a kind of steroid hormone produced by the zona glomerulosa(ZG)cells of the adre-nal cortex which plays a crucial regulatory role in fluid-electrolyte balance and blood pressure stability.Aldo-sterone biosynthesis is a calcium-dependent process,and ion channels play a key role in this process.Primary aldosteronism is closely related to mutations in ion channels.Recent studies have highlighted an intriguing rela-tionship between the unique rosette structure of ZG cells and their electrical excitability.Elucidating the con-nection between rosettes and ZG cell electrical excitability as well as aldosterone secretion leads to a deeper un-derstanding of the mechanisms regulating aldosterone secretion and may provide new insights into the pathogen-esis of primary aldosteronism.
