4. Schwann cells make the insulation for nerve cells, they are kind of like the white lines on the side of the road and guard rails for our information highways in our brains and nerves throughout our bodies. You could also think of them as the rubber around a wire. They are affected in multiple sclerosis patients because in multiple sclerosis the body attacks its own schwann cells. New research is being done in this field including transplants to regrow and repair the damaged schwann cells but is mostly preventive. In Multiple Sclerosis patients the crucial material, myelin, needed to coat the neurons is being eaten away. the body needs these cells to signal to the rest of the body effectively. when the body is unable to create this material, you begin to get Multiple Sclerosis.

Schwann cells are cells that are part of the nervous system, which warps around a nerve fiber and forms the nerve-insulating layer. Schwann cells are not affected greatly in multiple sclerosis, as MS is an autoimmune disease of the CENTRAL nervous system, and Schwann cells are only present in the PERIPHERAL nervous system. In the CNS, oligodendrocytes are responsible for insulating the axons with myelin, but are hardly affected in MS, as MS causes destruction of myelin, not the myelinating agents.
Schwann cells and oligodendrocytes
This questions has been answered below in the related discussions, "what are Schwann cells"
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
PNSCNSContinue along a single axonCoil around multiple axonsProduced by schwann cellsProduced by oligodendrocytesRegenerativeNon-regenerative
The Remaining Schwann Cells schwann cells, after injury and disruption to target, the remaining schwann cells undergo a rapid mitotic division until the target tissue is reached and the successful pathway is regenerated under the structural guidance of the schwann cells,
They are called oligodendrocytes but in the peripheral nervous system you would call them schwann cells.
Theodor Schwann concluded that all animal tissues were made of cells.
neurons
1) starting with the obvious; oligodendrocytes myelinate axons in the CNS whereas schwann cells myelinate axons in the PNS 2) a single oligodendrocyte is able to myelinate multiple axons whereas a schwann cell can only myelinate a single axon. 3) schwann cell myelination allows for axonal grown and regeneration where as oligodendrocytes inhibit axonal growth and regeneration. 4).... and probably a bunch more differences
oligodendrocytes
