概括
在胰腺小岛移植后,静脉注射D-粉改善了1型糖尿病模型小鼠的血糖控制. 这种治疗增强了胰岛素分泌,并保持了稳定的血糖水平,而不会影响移植细胞的存活率.
科学领域:
- 内分泌学和新陈代谢学
- 移植免疫学 移植免疫学
- 糖尿病学 糖尿病学
背景情况:
- 胰腺小岛移植是1型糖尿病的一种有前途的治疗方法,但改善长期结果和减少对外源性胰岛素的依赖仍然是一个挑战.
- 改善移植小岛的功能和生存对于实现持续的血糖控制和胰岛素独立至关重要.
研究的目的:
- 为了研究静脉注射D-allose在改善胰岛素分泌和血糖控制方面的疗效,在胰腺小岛移植后的1型糖尿病模型小鼠中.
- 评估D-allose对血糖水平,耐葡萄糖,以及移植胰腺小岛的活力和功能的影响.
主要方法:
- 1型糖尿病小鼠接受了胰腺小岛移植,并被分为两组:一组接受了静脉注射D-allose,对照组接受了盐水.
- 评估偶尔的血糖水平,进行腹腔内葡萄糖耐受性测试 (IPGGT),并分析了在移植的小岛屿中的细胞数量和特定基因 (caspase3,血氧酶1,氧化合成酶2) 的表达.
主要成果:
- 与对照组相比,用D-allose治疗的小鼠表现出明显较低和更稳定的血糖水平.
- IPGGT在接受D-素治疗的小鼠中显示出更好的葡萄糖处理,这是葡萄糖曲线下显著较低的增量面积所表明的.
- 在D-和对照组之间,在植入细胞或亡细胞的数量上没有发现显著差异.
结论:
- 静脉注射D-素有效改善高血糖,稳定血糖水平在1型糖尿病小鼠后岛屿移植.
- 在移植小岛中,D-粉似乎保持了胰岛素分泌的功能能力,而不会增加细胞存活率或减少细胞亡.

Hormones Regulating Blood Glucose
9.0K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
3.2K
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.
