WebMyelin oligodendrocyte glycoprotein (MOG) is a quantitatively minor component of CNS myelin whose function remains relatively unknown. As MOG is an autoantigen capable of producing a demyelinating multiple sclerosis-like disease in mice and rats, much of the research directed toward MOG has been immunological in nature. WebThe function of myelin will be discussed below. Microglia are, as the name implies, smaller than most of the other glial cells. Ongoing research into these cells, although not entirely conclusive, suggests that they may originate as white blood cells, called macrophages, that become part of the CNS during early development.

WebLeukodystrophy describes a group of more than 50 inherited neurological disorders. These diseases affect myelin, the protective covering on nerve cells in the brain and spine. Leukodystrophies cause a progressive loss of neurological function in infants, children and sometimes adults. Leukodystrophies affect about 1 in 7,000 live births.

Web19 Nov 2024 · The cell body includes a nucleus, which contains the genetic material of the cell. Dendrites which carry nerve impulses from neighbouring neurons towards the cell body. Axon carries impulses away from the cell body down the neuron; it is covered in a fatty layer of myelin sheath that protects the axon and speeds up electrical transmission. WebMyelin made by different cell types varies in chemical composition and configuration, but performs the same insulating function. Myelinated axons are white in appearance, hence the "white matter" of the brain. Myelin is composed of about 80% lipid and about 20% protein.
