In contrast, most of the axons in the core proximal to the retina (level 5) are remyelinated. 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. can they come on my property to repo my car
