近日,一项刊登在国际杂志PLOS Biology上的研究报告中,来自莱斯特大学的研究人员通过研究阐明了大脑中的神经元细胞之间彼此进行沟通的分子机制,相关研究或能帮助研究人员理解多种神经变性疾病发生的分子机制。

近日,一项刊登在国际杂志PLOS Biology上的研究报告中,来自莱斯特大学的研究人员通过研究阐明了大脑中的神经元细胞之间彼此进行沟通的分子机制,相关研究或能帮助研究人员理解多种神经变性疾病发生的分子机制。

文章中,研究者发现,人类机体中存在的重要分子—一氧化氮在调节大脑或外周神经元的功能上扮演着关键角色,从而就能帮助解析大脑中神经元之间沟通的分子机制。一氧化氮是一种信号分子,其参与了多种生理和病理性过程,比如能够帮助扩张血管、提高血液供应以及降低血压等。研究者表示,一氧化氮能够通过对突触信号的调节来调节神经元的功能,突触是两个神经元连接以及神经递质释放的位点。

研究者Steinert表示,这项研究中我们首次发现,复杂的蛋白质能被调节或修饰以便其能够调节突触和神经元的功能,这或许对于大脑的整体功能会产生较大的影响,而大脑必须不断调整来适应机体对不同需求的变化;这些影响也与神经疾病的发生直接相关,在多种神经疾病的发生过程中,一些具体的信号常常会出错而且会使得神经元失去功能。

这项研究还能帮助研究人员理解神经性疾病的发生过程,比如神经退行性疾病,如果研究者所发现的通路被破坏了,那么其就会干扰整个大脑的功能并且诱发神经元死亡。随后研究人员调查了黑腹果蝇机体中的神经通路,他们主要检测了果蝇大脑神经元功能所发生的变化或者单一神经元出现的激活现象。随后研究人员利用遗传学工具来表达特殊神经元中特定蛋白质的表达,他们希望能够利用多种方法来对神经元细胞中的特殊蛋白质和分子进行成像,从而检测神经元功能和位置所发生的改变。

Cell Metabol:星形细胞和神经元细胞间或存在乳酸盐的交换

图片来源:medicalxpress.com 神经细胞可以利用葡萄糖和乳酸盐来满足其高能量的需求,近日,苏黎世大学的科学家发现了新的证据,他们首次在完整的小鼠大脑中找到证据证实了不同大脑细胞间存在乳酸盐的交换,而这一研究证实了一个20多年的科学家假设。 相比其它器官而言,人类大脑具有最高的能量需求,而神经细胞的能量供给以及乳酸盐的特殊角色让科学家们研究了很多年,一项20世纪90年代的假设认

Nat Neurosci:瘦素可作用于非神经元细胞并影响进食

据在线发表于《自然—神经科学》上的一项研究称,饱胀感瘦素可以作用于大脑中的非神经元细胞并影响小鼠的进食行为。 瘦素是一类由体内脂肪细胞释放出的激素,具有调节进食行为和代谢的作用。Tamas Horvath等人发现调节进食和代谢的大脑区域——下丘脑中的星形胶质细胞中含有瘦素受体。 对负责编码星形胶质细胞中瘦素受体的基因进行删除,会改变受体的形状以及下丘脑中神经细胞形成的突触的数量。瘦素通常会抑制

Stem Cell Rep:可植入神经元细胞与小鼠大脑相融合

近日,刊登在国际杂志Stem Cell Reports上的一篇研究论文中,来自卢森堡大学等处的研究人员通过研究首次将皮肤细胞重编程后的神经元细胞成功植入到小鼠的大脑中,在植入后6个月神经元就实现了同大脑的完全融合,这项研究对于开发新型干细胞靶向疗法治疗诸如帕金森等神经系统疾病提供了新的希望。 研究者Jens Schwamborn及其同事一直致力于通过细胞移植的疗法来治疗神经变性疾病领域的研究

PLoS ONE:埃可病毒诱导神经元细胞死亡的机制

埃可30型肠道病毒(Echo30)能够引起无菌性脑膜炎,是目前研究得较热的人类肠道病毒(EVs)之一。目前,由Echo30感染所引起的显著临床结果的潜在机制还不明确。 近日,来自韩国国家卫生研究院的研究人员Doo-Sung Cheon发现,通过激活TRIO-RhoA信号,Echo30诱导了神经元细胞的死亡。相关论文发表在5月7日的PLoS ONE。 该研究的目的在于阐明Echo30感染所引起的

Nat Commun:科学家发现干细胞身份的新型调节子

自从被科学家们2006年发现以来,诱导多能干细胞(ipsCs)就成为了很多疾病治疗的希望,但深入研究多能干细胞身份的复杂调控机制或许对于研究人员而言非常困难,近日,一项刊登在国际杂志Nature Communications上的研究报告中,来自德国科隆大学的研究人员通过研究发现了一种通过多能干细胞来制造神经元细胞的有效新方法。
