在哺乳动物中,肾上腺皮质的肾上腺束状带(AZF)细胞对促肾上腺皮质激素(ACTH)的刺激有昼夜分泌糖皮质激素的反应。叠加在这种基本的分泌模式上,身体和心理压力通过激活下丘脑垂体肾上腺轴,触发ACTH刺激的皮质醇产生的爆发(Stewart和Krone,2011)。在包括牛和人在内的一些物种中,AngII也可能刺激皮质醇的分泌(Clyne等人,1993;Lebrethon等人,1994;Mlinar等人,1995)。皮质醇在调节从能量代谢到长期记忆形成的各种生理功能中起着关键作用(Stewart和Krone,2011;Chen等人,2012)。在细胞水平上,调节糖皮质激素产生的生化和离子机制只被部分了解。然而,在牛和啮齿类动物中,依赖去极化的钙离子进入的关键作用已经得到了很好的证实(Matthews和Saffran,1973;Lymangrover等人,1982;
In mammals, adrenal zona fasciculata (AZF) cells of the adrenal cortex secrete glucocorticoids in a diurnal pattern in response to stimulation by adrenocorticotropic hormone (ACTH). Superimposed on this basal secretory pattern, physical and psychological stress triggers bursts of ACTH-stimulated cortisol production by activation of the hypothalamic pituitary adrenal axis (Stewart and Krone, 2011). In some species, including bovine and human, AngII may also stimulate cortisol secretion (Clyne et al., 1993; Lebrethon et al., 1994; Mlinar et al., 1995). Cortisol acts pivotally in regulating physiological functions ranging from energy metabolism to long-term memory formation (Stewart and Krone, 2011; Chen et al., 2012). At the cellular level, the biochemical and ionic mechanisms that regulate glucocorticoid production are only partially understood. However, in bovine and rodents, a pivotal role for depolarization-dependent Ca2+ entry is well established (Matthews and Saffran, 1973; Lymangrover et al., 1982;
