Myelin in cns
WebMyelin on axons speeds signal conduction and is provided by different glial cells in the CNS and PNS. The nervous system has several types of glial cells, categorized by the anatomical division in which they are found. In the CNS, astrocytes, oligodendrocytes, microglia, and ependymal cells perform different functions that support neurons. WebHere, the tNPs circulated throughout vasculature into various organs, secondary lymphoid tissues and CNS, and contacted with myelin-reactive CD4 + and CD8 + T cells to …

WebThe P2 protein of bovine root myelin has chemical characteristics which differentiate it from other myelin basic proteins. The tryptic peptide map of the bovine P2 protein is distinctly different from the map of either the rabbit PI protein or the bovine CNS myelin basic protein. WebMyelin produced by oligodendrocyte and Schwann cells have both inhibitory molecules, but myelin residues in the peripheral nervous system are further eradicated after damage in comparison to the central nervous system. In the central nervous system, oligodendrocytes do not remove myelin residues.
