AIM
A semisynthetic primary bile acid (PBA) has exerted hypoglycemic effects in Type 1 diabetic animals, which were hypothesized to be due to its anti-inflammatory and cellular glucose-regulatory effects. Thus, the research purpose aimed to examine antidiabetic effects of a PBA, in terms of cellular inflammation and survival and insulin release, in the context of supporting β-cell delivery and Type 1 diabetic treatment.
MATERIALS & METHODS: 10 formulations were prepared, five without PBA (control) and five with PBA (test). Formulations were used to microencapsulate pancreatic β cells and the microcapsules were examined for morphology, cell viability, insulin release and inflammation.
RESULTS & CONCLUSION: PBA improved cell viability, insulin release and reduced inflammation in a formulation-dependent manner, which suggests potential use in cell delivery and diabetes treatment. [Formula: see text].
目的
一种半合成的初级胆汁酸（PBA）在1型糖尿病动物中具有降血糖作用，据推测这是由于其抗炎和细胞葡萄糖调节作用。因此，本研究目的旨在在支持β细胞递送和1型糖尿病治疗的背景下，从细胞炎症、存活和胰岛素释放方面研究一种PBA的抗糖尿病作用。
材料与方法
制备了10种制剂，5种不含PBA（对照），5种含PBA（试验）。用这些制剂对胰腺β细胞进行微囊化，并对微囊进行形态、细胞活力、胰岛素释放和炎症检测。
结果与结论
PBA以制剂依赖的方式提高了细胞活力、胰岛素释放并减轻了炎症，这表明其在细胞递送和糖尿病治疗中具有潜在用途。[公式：见正文]
