Myelin Repair as a Neuroprotective Strategy for Multiple Sclerosis: From Bench to Bedside

Area of Science:

• Neuroscience
• Immunology
• Regenerative Medicine

Background:

• Multiple sclerosis (MS) is a CNS neuro-inflammatory disease causing demyelination.
• Spontaneous remyelination by oligodendrocytes (OL) is often incomplete and variable.
• Demyelinated axons risk degeneration; successful remyelination offers neuroprotection.

Purpose of the Study:

• Review fundamental remyelination mechanisms in MS.
• Bridge basic science with clinical relevance.
• Evaluate remyelination assessment techniques and therapeutic strategies.

Main Methods:

• Literature review of remyelination processes.
• Analysis of in vivo imaging techniques for myelin repair.
• Examination of clinical trials for remyelination therapies.

Main Results:

• Remyelination involves OPC activation, differentiation, and myelin deposition.
• Microenvironment and signaling pathways balance inhibitory and pro-remyelinating factors.
• Successful remyelination is a promising target for neuroprotection in MS.

Conclusions:

• Remyelination is a key therapeutic target to prevent MS-related disability.
• Advances in assessment and therapy show promise but face challenges.
• Bridging basic research and clinical application is crucial for remyelination strategies.
