Studies of autoimmunity in multiple sclerosis.

J N Whitaker, D S Snyder

CRC Critical Reviews in Clinical Neurobiology

|January 1, 1984

Summary

Immune responses can damage the central nervous system myelin unit, comprising the myelin sheath and oligodendrocytes. This review examines myelin composition, oligodendrocyte characteristics, and immune-mediated diseases like multiple sclerosis.

Area of Science:

Neuroimmunology
Cellular Biology
Demyelinating Diseases

Background:

The central nervous system myelin unit, consisting of the myelin sheath and oligodendrocytes, is crucial for nerve function.
This unit is vulnerable to damage from various immune-mediated mechanisms.

Purpose of the Study:

To review the composition and properties of central nervous system myelin.
To explore the chemical and biological characteristics of oligodendrocytes.
To analyze immune-mediated damage to the myelin unit in experimental diseases and human multiple sclerosis.

Main Methods:

Literature review of existing research on central nervous system myelin.
Analysis of oligodendrocyte biology and function.
Examination of experimental models of demyelinating diseases.
Review of immunological findings in multiple sclerosis patients.

Main Results:

Central nervous system myelin has a complex composition essential for nerve insulation.
Oligodendrocytes are vital support cells for myelin maintenance and repair.
Immune-mediated factors, both cellular and humoral, can lead to myelin damage.
Immunological abnormalities are implicated in the pathogenesis of multiple sclerosis.

Conclusions:

Understanding the central nervous system myelin unit's components and vulnerabilities is key to addressing neuroimmunological disorders.
Immune-mediated mechanisms play a significant role in demyelinating diseases.
Further research into immunological abnormalities can inform therapeutic strategies for multiple sclerosis.
