Although chronic demyelination appears to be harmful for axonal survival in the long term, this effect may not be clinically measurable within the time frame of a clinical trial. A …
WebThe loss of axons because of lack of protection is what makes MS so debilitating. Degradation is considered to be worse than the effects of demyelination. Once an axon … WebMar 8, 2024 · The myelination of axons by oligodendrocytes is a highly complex cell-to-cell interaction. Oligodendrocytes and axons have a reciprocal signaling relationship in which oligodendrocytes receive cues from axons that direct their myelination, and oligodendrocytes subsequently shape axonal structure and conduction.
WebFeb 6, 2013 · Current dogma suggests that chronically demyelinated axons are at risk for degeneration, with axonal loss resulting in permanent disability in myelin disease. However, the trophic role of the myelin sheath in long-term axonal survival is incompletely understood. WebIn this study, we analysed axonal mitochondria within demyelinated, remyelinated and myelinated axons in post-mortem tissue from patients with multiple sclerosis and controls, as well as in experimental models of demyelination and remyelination, in vivo and in vitro.
