胰高血糖素样肽-1(7-36)酰胺(GLP-1)在回肠远端以及CNS中由胰高血糖素原加工而成。在外周中,GLP-1作为肠促胰岛素因子并显著抑制上消化道运动(“回肠制动”),后者可能涉及CNS。在CNS内,GLP-1具有饱腹效应,因为GLP-1给药至第三脑室可减少短期摄食量(和餐量),而GLP-1拮抗剂给药具有相反的效应。此外,某些脑区GLP-1受体的激活会引发强烈的味觉厌恶。CNS(脑干)中毒素和GLP-1诱导的神经元活动之间的相似性表明中枢GLP-1受体在中继内感受性应激中的作用。因此,CNS中区域性不同的GLP-1受体群体可能与饱腹感或不适有关。有人认为,GLP-1的饱腹和厌恶方面的服务稳态和非稳态功能方面的营养平衡的维护。
Glucagon-like peptide-1 (7-36) amide (GLP-1) is processed from proglucagon in the distal ileum as well as in the CNS. In the periphery, GLP-1 acts as an incretin factor and profoundly inhibits upper gastrointestinal motility ('ileal brake'), the latter presumably involving the CNS. Within the CNS, GLP-1 has a satiating effect, since administration of GLP-1 into the third cerebral ventricle reduces short-term food intake (and meal size), while administration of GLP-1 antagonists have the opposite effect. In addition, activation of GLP-1 receptors in certain brain regions elicits strong taste aversions. Similarities between toxin- and GLP-1-induced neuronal activity in the CNS (brain stem) suggest a role for central GLP-1 receptors in relaying interoceptive stress. Thus, regionally distinct GLP-1 receptor populations in the CNS may be involved in satiety or malaise. It is argued that the satiating and aversive aspects of GLP-1 serve homeostatic and nonhomeostatic functions with respect to maintenance of nutrient balance.
