Abstract
It has been repeatedly suggested that integrin is essential for neuronal migration. A new study proposes a link between Disabled-1 (Dab1) phosphorylation and alpha3 integrin signalling that is thought to drive the timely detachment of migrating neurons from the guiding radial glia fibers during early corticogenesis. This proposal however is hardly compatible with time-lapse anatomical investigations and genetic studies on integrin or with recent works which indicate direct reelin signalling to radial fibers.
