Expert Review of Neurotherapeutics
|December 1, 2015
Summary
Remyelination, the repair of myelin in multiple sclerosis (MS), is often incomplete. Current animal models assess drug potency for accelerating myelin repair, not inducing it, and remyelination may not prevent MS progression.
Area of Science:
- Neuroscience
- Immunology
- Pharmacology
Background:
- Multiple sclerosis (MS) involves demyelination, where the protective myelin sheath around nerves is damaged.
- Remyelination is the natural repair process, crucial for preventing axonal damage and disability in MS.
- Therapeutic strategies aim to promote remyelination to halt disease progression.
Discussion:
- This editorial critically evaluates experimental models used to discover remyelination-promoting drugs.
- Current animal models primarily assess the ability of drugs to accelerate existing myelin repair, not to initiate it.
- The effectiveness of remyelination in preventing progressive neurodegeneration and disability in MS remains uncertain.
Key Insights:
- Animal models may overestimate the therapeutic potential of remyelination-promoting drugs.
- Accelerating remyelination does not guarantee a halt in MS disease progression.
- Remyelination and neuroprotection might be distinct processes, requiring separate therapeutic targets.
Outlook:
- Further research is needed to develop models that can induce and assess true myelin repair.
- Investigating the interplay between remyelination and neuroprotection is critical for effective MS therapies.
- Developing therapies that target both myelin repair and neuroprotection may be essential for managing MS progression.

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...

2.0K
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...
