Tissue donations for multiple sclerosis research: current state and suggestions for improvement.

Area of Science:

• Neuroscience
• Immunology
• Pathology

Background:

• Multiple sclerosis (MS) research has advanced, yet fundamental questions regarding its cause and central nervous system (CNS) pathology persist.
• Key unresolved areas include disease etiology, immune triggers, inflammation, demyelination, neurodegeneration, and tissue repair mechanisms.
• Novel molecular technologies necessitate access to well-preserved MS brain and spinal cord tissues for comprehensive analysis.

Purpose of the Study:

• To assess the current availability and accessibility of post-mortem and biopsy-derived multiple sclerosis tissues.
• To identify limitations in accessing tissues from early and highly active disease stages.
• To propose recommendations for enhancing tissue donation, sampling, and preservation for MS research.

Main Methods:

• A comprehensive review of existing multiple sclerosis tissue collections was conducted.
• An expert initiative, under the European Charcot Foundation, analyzed the current state of MS tissue resources.
• Recommendations were formulated based on expert consensus regarding tissue acquisition and management.

Main Results:

• Existing brain banks provide some high-quality MS tissue, but material from early disease stages is limited.
• The study details currently available MS tissue resources and their accessibility.
• Recommendations address increasing tissue donation from early-stage patients and standardizing tissue sampling and preservation.

Conclusions:

• Improved access to diverse multiple sclerosis tissues, particularly from early disease stages, is critical for advancing research.
• Establishing a centralized registry of available tissues would enhance accessibility for researchers and clinicians.
• Standardized protocols for tissue donation, sampling, and preservation are essential for maximizing the utility of MS tissue resources.
