General description

The highly layered structure of the cerebral cortex is established through the pattern of neuronal cell migrations. The first step is the creation of the primordial layer, the preplate, consisting of radial glial cells and the earliest generated neurons. Among these neurons are the Cajal-Retzius neurons. In the next step, the preplate splits into a superficial (marginal) zone, where the Cajal-Retzius neurons reside, and a deep subplate wherein the neurons form. Neurons migrating from the subplate form the cortical plate. This migration takes place on the radial glial fibers. r> r>The reeler mutant in mouse displays an abnormal pattern of cell migration throughout the cerebral and cerebellar cortices. The preplate forms normally, and the neurons differentiate at the correct times in the ventricular zone. However, instead of forming the normal "inside-out" arrangement of neurons in the cortical plate, the older neurons are found furthest from the ventricular zone, while the younger neurons do not migrate far at all. The reeler cerebral cortex is inverted from that of the wild type mouse. r> r>The defect of the reeler mice appears to be in the production of an extracellular matrix protein by the Cajal-Retzius cells (D′Arcangelo et al., 1995, Nature 374:719-723.; Ogawa et al., 1995 Neuron 14:899-912.) This 388kDa protein is made by wild-type mice but not by the reeler mutants. It is thought that this Reelin protein is crucial for positioning the migrating neuron within the cortical plate (Figure 1). In the absence of Reelin, the migrating neuron would be "lost," and the cortical plate would be abnormal. We do not yet know the mechanisms by which Reelin informs the cells as to their position, how the cell responds to Reelin, and why the absence of reelin should give an "inverted" plate. However, the identification of the protein encoded by the reeler gene should allow us to begin these studies.
