Schematic view of intracellular signaling cascades triggered by receptor tyrosine kinase in Schwann cells. We propose that upregulation of MAG mRNA implies a transition from immature Schwann cell to the promyelinating state and that myelination will subsequently occur. Activation of both cAMP and Akt-GSK-3β signals and, at the same time, downregulation of MAPK are all required for MAG expression. At present, the targets of these three pathways are not known.
