Abstract: Reelin in neuronal migration It has long been known that the secreted factor Reelin is crucial for proper neuronal migration during the development of the cortex. However, the mechanistic actions leading to a Reelin response are less well known. Acker-Palmer and colleagues reveal that the axonal guidance cue ephrin B2 acts as a co-factor with Reelin receptors to initiate signalling cascades important to produce the proper lamination of the cortex. This additional role for ephrin B2 expands the functions for this developmental protein beyond proper axonal targeting to cell migration.
