There is a relation between stress and alcohol drinking. We show that the corticotropin-releasing hormone (CRH) system that mediates endocrine and behavioral responses to stress plays a role in the control of long-term alcohol drinking. In mice lacking a functional CRH1 receptor, stress leads to enhanced and progressively increasing alcohol intake. The effect of repeated stress on alcohol drinking behavior appeared with a delay and persisted throughout life. It was associated with an up-regulation of the N-methyl-d-aspartate receptor subunit NR2B. Alterations in the CRH1 receptor gene and adaptional changes in NR2B subunits may constitute a genetic risk factor for stress-induced alcohol drinking and alcoholism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sillaber, Inge -- Rammes, Gerhard -- Zimmermann, Stephan -- Mahal, Beatrice -- Zieglgansberger, Walter -- Wurst, Wolfgang -- Holsboer, Florian -- Spanagel, Rainer -- New York, N.Y. -- Science. 2002 May 3;296(5569):931-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute of Psychiatry, Kraepelinstrasse 2-10, 80804 Munich, Germany. sillaber@mpipsykl.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11988580" target="_blank"〉PubMed〈/a〉
