Excessive alcohol consumption is a major health and social issue in our society. Pharmacologic administration of the endocrine hormone fibroblast growth factor 21 (FGF21) suppresses alcohol consumption through actions in the brain in rodents, and genome-wide association studies have identified single nucleotide polymorphisms in genes involved with FGF21 signaling as being associated with increased alcohol consumption in humans. However, the neural circuit(s) through which FGF21 signals to suppress alcohol consumption are unknown, as are its effects on alcohol consumption in higher organisms. Here, we demonstrate that administration of an FGF21 analog to alcohol-preferring non-human primates reduces alcohol intake by 50%. Further, we reveal that FGF21 suppresses alcohol consumption through a projection-specific subpopulation of KLB-expressing neurons in the basolateral amygdala. Our results illustrate how FGF21 suppresses alcohol consumption through a specific population of neurons in the brain and demonstrate its therapeutic potential in non-human primate models of excessive alcohol consumption.

BACKGROUND: Both diabetes mellitus and alcohol consumption are prevalent in the United States, yet physicians are poorly informed about how alcohol use affects risk for or management of diabetes. PURPOSE: To conduct a systematic review assessing the effect of alcohol use on the incidence, management, and complications of diabetes mellitus in adults. DATA SOURCES: English-language studies in persons 19 years of age or older that were identified by searching the MEDLINE database from 1966 to the third week of August 2003 and the reference lists of key articles. STUDY SELECTION: Two independent assessors reviewed 974 retrieved citations to identify all experimental, cohort, or case-control studies that assessed the effect of alcohol use on diabetes risk, control, self-management, adverse drug events, or complications. DATA EXTRACTION: Two independent reviewers extracted data and evaluated study quality on the basis of established criteria. DATA SYNTHESIS: Thirty-two studies that met inclusion criteria were reviewed. Compared with no alcohol use, moderate consumption (one to 3 drinks/d) is associated with a 33% to 56% lower incidence of diabetes and a 34% to 55% lower incidence of diabetes-related coronary heart disease. Compared with moderate consumption, heavy consumption (>3 drinks/d) may be associated with up to a 43% increased incidence of diabetes. Moderate alcohol consumption does not acutely impair glycemic control in persons with diabetes. CONCLUSIONS: Moderate alcohol consumption is associated with a decreased incidence of diabetes mellitus and a decreased incidence of heart disease in persons with diabetes. Further studies are needed to assess the long-term effects of alcohol consumption on glycemic control and noncardiac complications in persons with diabetes.
