胎盘

环球科学 2009年第10期 69-69页

作者：达维德·卡斯泰尔韦基（davide Castelvecchi）冯泽君（译）曹丽敏（校）

1.2亿年前，当巨型恐龙还在森林里大打出手时。白垩纪的草丛中却上演了安静的一幕：一种小巧的毛茸茸的生物不再下蛋了。而是开始直接产下年幼个体。它们就是几乎所有现代哺乳动物（其中只有鸭嘴兽和针鼹鼠到现在还是卵生）的祖先。

碳

环球科学 2009年第10期 69-69页

作者：达维德·卡斯泰尔韦基（davide Castelvecchi）冉隆华（译）罗绮（校）虞骏（校）

虽然最近因为与温室气体的瓜葛而获得恶名，但碳一直都是地球生命的同义词。毕竟，“碳基生命”经常用于表示“我们所知的那种生命”，而“有机分子”则意味着“碳基分子”，哪怕不牵涉任何有机体。

电池

环球科学 2009年第10期 59-59页

作者：达维德·卡斯泰尔韦基（davide Castelvecchi）王昊明（译）申宁馨（校）虞骏（校）

电池的能量来源于电荷在不同物质问转移的趋势——这就是1799年底意大利科学家亚历山德罗·伏打（Alessandro Volta）制造世界上第一块电池时，想要探索利用的能量。

小胶质细胞是大脑的常驻巨噬细胞,通过感知神经元活动并支持突触重塑和可塑性积极促进脑实质的稳态。虽然已有研究表明星形胶质细胞在睡眠中的不同作用,但小胶质细胞在调节睡眠/觉醒周期和白天不同阶段调节突触活动中的作用尚未深入研究。以光作为授时提示,我们研究了用集落刺激因子-1受体拮抗剂PLX5622消除小胶质细胞对雄性小鼠睡眠/觉醒周期和海马突触传递的影响。我们的数据表明,小胶质细胞几乎完全的耗竭会增加NREM睡眠的持续时间并减少海马兴奋性神经传递。由于cx3cr1GFP/GFP小鼠显现与PLX5622处理的小鼠中发现的相同情况,趋化因子fractalkine受体CX3CR1在这些效应中起相关作用。此外,在光照阶段小胶质细胞表达较低水平的cx3cr1;当培养的小胶质细胞受到ATP(一种在睡眠期间释放的嘌呤能分子)的刺激时其cx3cr1表达降低。我们的研究结果表明,小胶质细胞参与调节睡眠,调整其cx3cr1表达以响应光/暗阶段,并以时相依赖性方式调节突触活动。

小胶质细胞是调节大脑突触发育和可塑性的重要细胞类型,但其影响突触的正常功能的机制尚不清楚。在本研究中,我们通过PLX5622造成小胶质细胞耗竭,并观察其对成年野生型小鼠海马CA3-CA1突触的影响。在小胶质细胞耗竭后,与树突棘密度降低相关的自发和诱发谷氨酸能活动的减少,出现未成熟突触特征以及突触的可塑性提高。小胶质细胞耗竭的小鼠在新物体识别任务的获取方面表现出缺陷。海马星形胶质细胞出现增生,但并没有神经炎症反应。在Cx3cr1-/-小鼠中,PLX不能导致海马出现上述改变。这说明CX3CL1/CX3CR1轴在小胶质细胞对突触功能的控制中有重要作用。PLX5622停用后,小胶质细胞的重新增殖,海马突触恢复,小鼠的学习功能也出现恢复。综上所述,小胶质细胞对维持成人大脑的突触的正常功能用重要的作用,去除小胶质细胞会导致谷氨酸能突触组织和活动的可逆变化。
