  • Cell Biology

Background:

  • Oligodendrocytes are crucial for myelination in the central nervous system (CNS).
  • Microglia, the resident immune cells of the brain, interact with oligodendrocytes.
  • Understanding glial cell interactions is vital for CNS health and disease.

Purpose of the Study:

  • To review oligodendrocyte-orchestrated myelination and myelin repair.
  • To highlight the multifaceted roles of microglia in myelin regeneration.
  • To discuss novel aspects of glial cell function and emerging research areas.

Main Methods:

  • Literature review synthesizing current research on oligodendrocytes and microglia.
  • Analysis of cellular and molecular mechanisms underlying myelination and remyelination.
  • Exploration of recent advancements in preclinical models and microbiome research.

Main Results:

  • Oligodendrocytes actively manage myelination and repair processes.
  • Microglia exhibit both beneficial and detrimental effects on myelin regeneration.

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Nervous Tissue: Myelin

The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

Nervous Tissue: Glial Cells

Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial...
