ENDOCR J:维生素A与糖尿病的关系

2017-06-14 佚名 medicalxpress

一直以来,科学家们都不清楚维生素A与糖尿病之间的关系,但是最近的一项研究表明,维生素A可以改善胰岛素产生β-细胞的能力。

一直以来,科学家们都不清楚维生素A与糖尿病之间的关系,但是最近的一项研究表明,维生素A可以改善胰岛素产生β-细胞的能力。

研究人员首次发现胰岛素β-细胞表面包含大量维生素A受体,研究人员表示:“人类细胞没有不必要的表面受体,他们都存在都是有目的的,在许多情况下,我们对它们存在的原因并不清楚,因此,暂时称它们为“孤儿”受体。当我们发现胰岛素细胞的细胞表面的维生素A受体时,我们认为找出细胞表面受体与维生素A相互作用的关键所在。”

研究人员认为,在这种特殊的情况下,维生素A的发展在细胞生命早期阶段发挥着重要作用,尤其是在病理生理条件下。

来自哥德堡大学国王学院(伦敦)和牛津糖尿病中心的研究人员们找到受体表面220个不同功能的β细胞,它们的功能仍不得而知,但是他们发现,其中一个就是维生素A受体。

通过实验室实验,研究人员发现,在维生素A减少的情况下,细胞的抗炎症能力减少,维生素A完全缺乏的情况下,细胞死亡。这一发现很可能是对于某些早期细胞发育不完全的1型糖尿病的重要解释。

这也是为什么在很多国家都规定,婴幼儿一定要补充适量的维生素A,接下来,研究人员将把研究重心放在解决维生素A与2型糖尿病的关系,希望有更多的重大发现。

Faseb J:维生素A会造成肥胖和糖尿病?

【维生素A+高脂饮食=肥胖和糖尿病风险增加】维生素A是人体维持正常运作需要的重要营养物质。但是今天在芝加哥的“实验生物学2017”实验生物学年会上提出的新研究表明,高脂肪饮食中正常水平的维生素A可能会对与葡萄糖和脂肪代谢相关的肝脏基因的表达产生负面影响。研究人员给两组老鼠喂食高脂肪饮食8周。一组消耗正常量的维生素A(“足够”),而另一组则食用缺乏该营养物质(“缺乏”)的食物。研究小组每周测量大鼠体

Nature Immunology:维生素A对于保护机体对抗血吸虫感染的重要作用

肝脏的肉芽肿是由炎症反应引起的,因为聚集了密集的巨噬细胞所组成的组织结构。研究人员发现,在感染了曼氏血吸虫后,在虫卵周围形成的肝肉芽肿是机体产生2型免疫反应的结果。对限制组织损伤和肝毒性以及控制寄生虫有重要作用。在缺乏维生素A的情况下,肝脏的肉芽肿的缺失,这表明机体不能有效的将M2型局势细胞转化成M1局势细胞,从而可能导致蠕虫感染期间发生的炎症反应缺陷。

Acta Neuropathol:缺乏维生素A易患阿尔茨海默氏症?不一定

提起阿尔茨海默氏症,人们往往将其与老年痴呆相关联。这是因为阿尔茨海默氏症患者确实以65岁以上的老年人为主,而且在所有的老年痴呆人群中阿尔茨海默氏症占的比例相当大。但是该病真是从人的老年才开始吗?最近一项研究表明,阿尔茨海默氏症的“病根”可能在人出生前就落下了。 阿尔茨海默氏症源头可追溯到出生前 “已有的研究表明,人到了一定年龄,大脑中开始产生β淀粉样蛋白并形成富集,对大脑附近的神经元

重磅:华人科学家发现阿尔茨海默病的源头或可追溯到出生前

近期,来自加拿大不列颠哥伦比亚大学(University of British Columbia)的宋伟宏教授团队和重庆医科大学附属儿童医院的李廷玉教授团队,在阿尔茨海默病开始的时间这个问题上,有了最新的惊人发现:如果胎儿或新生儿没有获得足够的维生素A,导致阿尔茨海默病的生物化学反应可能在婴儿还在子宫内或刚出生后就开始了。他们的这一重要研究成果刊登在神经学领域的著名期刊《Acta Neuropat

Blood:干细胞移植后补充维生素A可能能抑制移植物抗宿主病的发生

这些数据支持了研究人员的假设,即低水平的维生素A积极促进胃肠道发生移植物抗宿主病的概率。未来补充维生素A可能会改善移植结果。

Cell:缺乏维生素A会让你丢失宝贵的造血干细胞

德国癌症研究中心和海德堡干细胞研究与实验医学研究所的研究人员发现身体缺乏维生素A会造成骨髓中的造血干细胞丢失。这一发现不仅证实从平衡饮食中摄入充足的维生素A非常重要,加强我们对血细胞发育的理解,而且有可能为癌症治疗打开新的局面。相关研究结果于2017年5月19日发表在Cell期刊上。1、造血干细胞平时是休眠的骨髓中存在一群非常特殊的成体干细胞,即造血干细胞。造血干细胞在大多数时间里处于休眠状态,而
