In the peripheral nervous system, Schwann cells … WebThe action potential is a brief change of the membrane potential, caused by opening of channels that allow cations (especially Na +) to enter the neuron, followed by an outward flow of K + ions. A net influx of cations reduces the membrane potential by making the interior less negative.
WebIntroduction. Myelin basic protein (MBP), a major protein of the myelin sheath, is encoded by the Golli (genes of oligodendrocyte lineage)-MBP gene in myelinating glia and immune cells. 1 Several size isoforms of classic MBP are formed by differential splicing of a single mRNA transcript. The major MBP isoform in the adult human and bovine CNS is 18.5 … WebThis achievement shows that it is possible to encourage the regeneration of the myelin sheath by inhibiting the action of PTPRZ in endogenous oligodendrocyte precursor cells, indicating a new potential treatment for demyelinating diseases.
