在哺乳动物大脑皮层,控制兴奋性投射神经元和抑制性中间神经元整合到平衡的局部电路的发育事件知之甚少。我们报道,不同亚型的投射神经元独特而不同地决定皮层中间神经元的层状分布。我们发现,在Fezf2−/−皮层中,脑下投射神经元的完全缺失和胼胝体投射神经元的替代导致中间神经元层压明显异常和gaba能抑制的改变。此外,皮层下皮质神经元或胼胝体神经元的实验生成足以将皮质中间神经元招募到这些异位位置。引人注目的是,产生的投射神经元的身份,而不是严格的出生日期,决定了招募的中间神经元的特定类型。这些数据表明,在新皮层中,单个群体的投射神经元细胞从外部控制中间神经元的层状命运和局部抑制回路的组装。
In the mammalian cerebral cortex, the developmental events governing the integration of excitatory projection neurons and inhibitory interneurons into balanced local circuitry are poorly understood. We report that different subtypes of projection neurons uniquely and differentially determine the laminar distribution of cortical interneurons. We find that in Fezf2−/− cortex, the exclusive absence of subcerebral projection neurons and their replacement by callosal projection neurons cause distinctly abnormal lamination of interneurons and altered GABAergic inhibition. In addition, experimental generation of either corticofugal neurons or callosal neurons below the cortex is sufficient to recruit cortical interneurons to these ectopic locations. Strikingly, the identity of the projection neurons generated, rather than strictly their birthdate, determines the specific types of interneurons recruited. These data demonstrate that in the neocortex individual populations of projection neurons cell-extrinsically control the laminar fate of interneurons and the assembly of local inhibitory circuitry.
