大脑皮层的复杂形成需要一系列协调良好的事件,这些事件在细胞自主和非细胞自主机制的水平上受到调节。尽管调节皮质发育的细胞自主机制已得到充分研究,但对非细胞自主机制仍知之甚少。无偏筛选使我们能够将自分泌运动因子 (ATX) 识别为神经干细胞的非细胞自主调节因子。 ATX(也称为 ENPP2)最出名的是催化溶血磷脂酸 (LPA) 的产生。我们的结果表明,ATX 以细胞自主和非细胞自主的方式影响神经祖细胞的定位和粘附,并且引人注目的是,这种活性与其产生 LPA 的催化活性无关。
The intricate formation of the cerebral cortex requires a well-coordinated series of events, which are regulated at the level of cell-autonomous and non-cell autonomous mechanisms. Whereas cell-autonomous mechanisms that regulate cortical development are well-studied, the non-cell autonomous mechanisms remain poorly understood. A non-biased screen allowed us to identify Autotaxin (ATX) as a non-cell autonomous regulator of neural stem cells. ATX (also known as ENPP2) is best known to catalyze lysophosphatidic acid (LPA) production. Our results demonstrate that ATX affects the localization and adhesion of neuronal progenitors in a cell autonomous and non-cell autonomous manner, and strikingly, this activity is independent from its catalytic activity in producing LPA.
