Would multiple sclerosis affected schwann cells or oligodendrocytes?

Answer 1

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.

Answer 2

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.

Answer 3

SummaryDeficits in executive function and the relationship to frontal lesion load as detected on MRI were investigated in 42 multiple sclerosis patients. A battery of neuropsychological test examining executive skills including computerized tests of planning and spatial working memory was administered to all subjects. Performance on these tests was impaired in the patient group when compared with a group of matched controls, but not all executive skills were affected to the same extent. Although a number of executive test scores correlated with the severity of frontal lesion load, it was difficult to disentangle the specific contribution of frontal lobe pathology to the impairment on executive tasks. This study highlights the difficulties in attempting to attribute specific cognitive abnormalities to focal brain pathology in the presence of widespread disease such as in multiple sclerosis.
