尽管对重复应激暴露的快速反应习惯化是下丘脑-垂体-肾上腺(HPA)轴的一个关键特征,但一些研究表明,这种HPA反应模式存在大量的个体间差异。为了进一步研究这一重要神经内分泌系统对社会心理压力适应的个体差异,研究人员对54对男性双胞胎进行了三次中度社会心理压力暴露,每次暴露间隔为1周。同时进行acth1 - 24刺激试验(1μg)和地塞米松抑制试验(0.5mg)。虽然在压力暴露中平均皮质醇和ACTH反应的预期下降被观察到,但只有52%的受试者表现出这种有充分证据的普遍下降,近16%的参与者甚至表现出反应敏化。此外,弱的习惯化与第一次应激暴露和ACTH挑战的低皮质醇反应有关。此外,遗传分析没有揭示任何证据表明个体皮质醇反应习惯化具有实质性的遗传性,或者这种习惯化与糖皮质激素受体基因的两种常见多态性之间存在关联。
Although a rapid response habituation to repeated stress exposure is a key characteristic of the hypothalamus–pituitary–adrenal (HPA) axis, several studies document a substantial inter-individual variability of such HPA response patterns. In order to further investigate the individual differences in the habituation of this important neuroendocrine system to psychosocial stress, 54 male twin pairs were exposed to moderate psychosocial stress on three occasions, each exposure separated by a 1-week interval. Additionally, an ACTH1–24stimulation test (1μg) and a dexamethasone suppression test (0.5mg) were performed. Although on average the expected decrease of mean cortisol and ACTH responses across stress exposures was observed, only 52% of the subjects showed this well-documented general decline and almost 16% of the participants even showed a response sensitization across sessions. Furthermore, a weak habituation was related to low cortisol responses to both the first stress exposure as well as the ACTH challenge. Moreover, genetic analyses did not reveal any evidence for a substantial heritability of the individual cortisol response habituation or an association between this habituation and two common polymorphisms in the glucocorticoid receptor gene.
