本周Science发表一篇文章表明在杏仁体上,酒精通过CRF增加GABA能受体传递,从而引发各种酒精相关的症状和疾病。
The central amygdala (CeA) plays a role in the relationship among stress, corticotropin-releasing factor (CRF), and alcohol abuse. In whole-cell recordings, both CRF and ethanol enhanced -aminobutyric acid–mediated (GABAergic) neurotransmission in CeA neurons from wild-type and CRF2 receptor knockout mice, but not CRF1 receptor knockout mice. CRF1 (but not CRF2) receptor antagonists blocked both CRF and ethanol effects in wild-type mice. These data indicate that CRF1 receptors mediate ethanol enhancement of GABAergic synaptic transmission in the CeA, and they suggest a cellular mechanism underlying involvement of CRF in ethanol's behavioral and motivational effects.
