【先进的免疫疗法对糖尿病治疗显示出极大希望】根据8月9日在“科学转化医学”杂志上发表的一项临床试验的结果,“重新训练”免疫系统减缓1型糖尿病的进展可能成为现实。

在伦敦国王学院和加的夫大学领导MonoPepT1De试验的研究人员观察到注射了肽类——胰腺β细胞中发现的蛋白质分子的小片段的1型糖尿病患者的免疫系统的行为显着变化。

当患者的免疫系统错误地攻击胰腺中产生胰岛素的β细胞时,发生1型糖尿病。不治疗,β细胞的数量将缓慢下降,身体将不再能维持正常的血糖(血糖)水平。

该试验由Mark Peakman教授领导,他的工作得到了国家健康研究所(NIHR)生物医学研究中心(BRC)在Guy和圣托马斯NHS基金会信托基金会和伦敦国王学院的支持,他说:“当有人被诊断患有1型糖尿病,通常他们的β细胞在15%至20%之间,我们想看看我们是否可以通过再培训免疫系统来保护这些剩余的细胞来停止攻击他们。

“我们还有很长的路要走,但是这些早期的研究结果表明我们正在朝着正确的方向前进。我们试用的肽技术不仅在这个阶段对患者来说似乎是安全的,而且也具有明显的效果对免疫系统。”

目前还没有治愈1型糖尿病,这种疾病可以影响身体的主要器官,包括心脏,血管,神经,眼睛和肾脏。英国是世界上1型糖尿病患病率最高的国家之一,现在有40万人生活在这个疾病当中。

“接受治疗的人需要更少的胰岛素来控制他们的血糖水平,这表明他们的胰腺工作良好”卡迪夫大学的Colin Dayan教授,研究的临床首席研究员说道。

该研究也得到了英国糖尿病和JDRF,1型糖尿病慈善机构的支持。

英国糖尿病研究主任Elizabeth Robertson博士,支持该研究的主要作者的慈善机构表示:“英国致力于增加对1型糖尿病免疫攻击的理解,并设法阻止它们。研究结果是令人兴奋的一步,使用免疫治疗来预防这种严重疾病发生在高风险患者身上,或阻止它们在已经诊断的患者中进展。”

Karen Addington是英国首席执行官,负责研究的1型糖尿病慈善机构JDRF,他说:“这种令人兴奋的免疫治疗研究增加了胰岛素生产细胞可以被保护和保存的可能性,这意味着有风险的人有一天,1型糖尿病可能需要减少胰岛素,也许看到一个未来,任何人都不会再面临每日注射以保持生命。”

UCB已经从伦敦国王学院到MonopepT1De和MultipepT1De全球获得了独家许可。

Nat Commun:不同亚型的胰岛β细胞或影响糖尿病患者的疗法

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

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。

Cell Metab:糖尿病治疗新思路:让胰岛β细胞“High”起来

最近,加州大学圣地亚哥分校(UCSD)的研究人员采用单细胞RNA测序,首次揭示了调控胰岛β细胞生长的信号通路,有望以此诱导其再生,从而为糖尿病的治疗带来了新的线索。这一成果发表在《细胞》子刊《Cell Metabolism》上。

JCEM:胰腺脂肪沉积对胰岛β细胞减少的影响

糖尿病是由于胰岛素绝对或相对不足引起的一种以慢性高血糖为特征的代谢性疾病,胰岛β细胞功能损伤和/或数量减少是各型糖尿病的共同特征和发病基础。2型糖尿病的一大特征在于胰腺中胰岛素表达水平降低。科学家们通常认为这种下降的原因在于这种器官中胰岛β细胞死亡。但是在2型糖尿病病人的胰腺中,人们很少发现死亡的β细胞。而且胰腺功能障碍与死亡的β细胞数量不成比例。目前的研究仍无法解释2型糖尿病(T2DM)患者胰岛

Cell Metabolism:治疗糖尿病新方法:胰岛β细胞新发现

1型糖尿病患者的胰腺中产生胰岛素的β细胞死亡,而且无法被取代,没有这些β细胞死亡,身体也就失去了控制血糖的能力。日前,加州大学的研究人员已经发现了再生β细胞的新途径,深刻理解了糖尿病以及健康新陈代谢背后的机制。

JAMA:胰岛β细胞再生新方法

加利福尼亚大学研究人员的一项研究显示,新研发的阶梯式过程能将小鼠皮肤细胞转化为分泌胰岛素的β细胞。Hampton博士对此进行了报道,文章发表在2014年4月2日的The Journal of American Medical Association上。【原文下载】当研究人员采用独特的分子和重组因子混合物处理成纤维细胞时,这些细胞转化为内胚层样细胞。进一步用其它化合物处理,细胞转化为胰腺祖细胞样细胞
