- 内分泌学 在内分泌学.
- 生物医学工程 生物医学工程
背景情况:
- 同步肠道电刺激 (SIES) 将电刺激与小肠内在的慢波同步.
- 在加速小肠过渡方面,SIES已经显示出比固定频率肠电刺激 (IES) 更大的效果.
- 这项研究调查了SIES通过影响GLP-1和胰岛素分泌来抑制食后血糖的潜力.
研究的目的:

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
1.3K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
