近日,刊登在国际杂志Nature Communications上的一项研究论文中,来自俄勒冈健康与科学大学(Oregon Health And Science University)等机构的研究人员通过研究发现了至少四种不同的人类胰岛素β细胞亚群的存在,这或许对于理解糖尿病的发病机制及开发新型糖尿病疗法提供了新的线索。

研究者Grompe表示,这项研究首次描述了多种不同类型的人类胰岛素β细胞,其中有些细胞相比其它细胞而言可以更好地释放胰岛素,而其它细胞则会进行快速再生过程;因此携带不同比例的亚型胰岛素β细胞的人们或许就更易于患上糖尿病,而后期对细胞特性的深入理解或许可以帮助我们揭开新型疗法开发的大门,同时也可以帮助解释为何某些人易患糖尿病,而其他人则不必易患该病。

糖尿病在美国影响着2900万人的健康,其是由产生胰岛素的β细胞的缺失或功能异常所引发,而胰岛素β细胞可以帮助维持机体的正常血糖水平;此前研究者仅发现了单一类型β细胞的存在;然而本文研究中,利用人类胰岛或至少4000个细胞组成的细胞“集团”进行研究,

研究者Grompe及其同时就发现了一种新方法可以鉴别并且分离出不同类型的胰腺β细胞;同时研究者还发现,在不同类型的细胞间,成百上千个基因存在着不同的表达情况,而且其可以产生不同水平的胰岛素。所有的2型糖尿病患者机体中的β细胞亚型都存在着异常的比例,这就表明β细胞类型的比例关系在疾病发生发展过程中的重要作用。

最后研究者表示,后期我们还需要进行更为深入的研究来确定不同形式的糖尿病和其它疾病影响新型细胞亚型的分子机制,同时研究者还希望通过深入的研究开发出针对不同糖尿病的新型治疗方法。

JECM:GLP-1敏感性存在个体差异,与胰岛素抵抗无关

GLP-1是由肠道分泌的肠促胰岛素,对调节葡萄糖耐量起重要作用。在糖尿病患者和健康人中,GLP-1都可以促进胰岛素分泌。但是,不同人的胰岛β细胞对GLP-1的敏感性是否存在差异,这些差异是什么因素造成的,目前并相关研究。最近,有研究试图揭开这一谜题。研究者选取健康的肥胖和非肥胖个体进行队列研究,研究结果不仅证明胰岛β细胞对GLP-1的敏感性存在个体差异,而且证明这种差异与胰岛素敏感性不相关。

JCEM:利拉利汀对胰岛β细胞具有保护作用

在糖尿病,抑制二肽基肽酶–4(DPP–4)是一种增加GIP和GLP–1,诱导胰岛素分泌的有效治疗策略。了解被批准用于2型糖尿病治疗的新药是否能直接影响β细胞是非常重要的。为了探讨利拉利汀,一种新型的DPP–4抑制剂,对β细胞功能和存活的影响,来自德国不莱梅大学的Kathrin Maedler教授及其团队进行了一项研究,该研究发现新型的DPP–4抑制剂利拉利汀保护人类胰岛不受糖毒性、脂毒性和细胞毒性
