Schwann Cells (Peripheral Nervous System) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Schwann cells are the principal glial cells of the peripheral nervous system (PNS), providing myelination, support, and regeneration capacity. They are essential for nerve conduction, Wallerian degeneration, and nerve regeneration after injury.
Schwann cells wrap around axons in the PNS, forming either compact myelin (in myelinating Schwann cells) or loose membranes (in non-myelinating Remak bundles). Their role in nerve function and repair is critical.
