Brain Res Mol Brain Res ; — Indeed, in the peripheral nervous system it is now well established that axonal als are mandatory at all the stages of Schwann cell precursors development into myelin-forming cells and that the al for nerve engulfment and ensheathment originates in axons with which mature Schwann cells interact. At the time of myelination, the existence of a specific axonal al allowing oligodendrocyte processes to recognize axons from dendrites, has been put forward and the induction of the myelination process seems to depend on neuronal electrical activity.

Until recently, it was generally assumed that, in contrast to Schwann cells, oligodendrocytes developed independently from neurons.

Oligodendrocytes, in the central nervous system CNSand Schwann cells, in the peripheral nervous system PNShave the unique ability to synthesize nedveux amounts of membrane that wrap around axons and compact to form myelin. The effects of psychological stress on humans: increased production of proinflammatory cytokines and a Th1-like response in stress-induced anxiety. The close interaction between axons and myelin forming cells, suggests the existence of mutual cross-talks between the neurons and their myelinating partners.
