Science:巨噬细胞竟是维持乳腺干细胞的“摇篮”
为了更好地理解乳腺干细胞如何调节乳腺发育以及它们如何发生癌变,来自美国和荷兰的研究人员研究了巨噬细胞如何通过分子信号传导机制与乳腺干细胞相互作用。他们发现巨噬细胞在维持乳腺干细胞微环境(niche)中发挥重要的作用。相关研究结果于2018年5月17日在线发表在Science期刊上,论文标题为“Notch ligand Dll1 mediates cross-talk between mammary stem cells and the macrophageal niche”。论文通信作者为美国普林斯顿大学的Yibin Kang教授和Rumela Chakrabarti博士。[查看]

重磅!构建出将皮肤细胞转化为神经元的重编程配方
在一项新的研究中,美国斯克里普斯研究所的Kristin Baldwin教授及其团队想要知道简化和扩展让利用皮肤细胞直接制造出神经元的编码工具盒(coding toolbox)是否是可能的。Baldwin实验室成员Rachel Tsunemoto博士在之前的一项研究中已提示着一次仅利用两种转录因子产生特定类型的神经元是可能的(Nature Neuroscience, 2015, doi:10.1038/nn.3887)。因此,她和其他的实验室成员设计和测试了大量的双转录因子编码以便观察它们是否能够将皮肤细胞转化为具有神经元基本核心特征(比如它们的形状和电兴奋性)的细胞。[查看]

Nat Neurosci:帕金森症关键蛋白研究新进展
帕金森症以及其它神经退行性疾病患者的大脑中往往存在一些特定蛋白沉积,这也是相关疾病的诊断标准之一。然而,这些蛋白质在正常的大脑活动中的功能目前并不清楚。如今,来自UCSF的神经学家Robert Edwards等人发现了帕金森症患者大脑中一种叫做alpha-synuclein的蛋白质的生理功能,作者认为这一信息能够为相关疾病的预防提供一定的线索。这也是目前第一次对神经退行性疾病相关的蛋白质的正常生理功能进行研究。[查看]

Cell:为何免疫系统检测不到癌症?
癌症隐藏在免疫系统的视线之下。当癌细胞出现时,身体的天然肿瘤监控程序应当能够检测和攻击它们,而且仅当这些防御系统都失效时,癌症才能茁壮成长。在一项新的研究中,来自美国布莱根妇女医院的Niroshana Anandasabapathy博士和他的团队在30种在人外周组织(peripheral tissue)内发生的癌症(包括黑色素瘤皮肤癌)中发现一种至关重要的可能被一些癌症用来伪装自己的策略(即一种遗传程序)。[查看]
