# Oligodendrocytes Are Active Participants in the Pathogenesis of Multiple Sclerosis and Its Animal Models

## TL;DR

This paper reviews recent findings showing that oligodendrocytes actively contribute to the development of multiple sclerosis and its animal model, rather than being just passive victims.

## Contribution

The paper highlights the novel perspective that oligodendrocytes play active roles in the progression of MS and EAE, challenging previous assumptions.

## Key findings

- Oligodendrocytes are not merely targets but active participants in MS and EAE pathogenesis.
- Recent studies reveal dynamic roles of oligodendrocytes in autoimmune inflammation and demyelination.
- This review compiles evidence supporting a shift in understanding of oligodendrocyte function in these diseases.

## Abstract

Multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis (EAE) are autoimmune inflammatory demyelinating diseases of the central nervous system (CNS). For decades, oligodendrocytes were regarded as passive targets of autoimmune inflammation in these conditions. However, recent studies challenge this view, revealing that oligodendrocytes are active participants—not just passive targets—in the pathogenesis of MS and EAE. In this review, we summarize recent research that highlights the active and dynamic roles of oligodendrocytes in these diseases.
