B Cells in Multiple Sclerosis and Virus-Induced Neuroinflammation

Area of Science:

• Neuroimmunology
• Central Nervous System (CNS) Inflammation

Background:

• Neuroinflammation involves immune responses within the CNS, triggered by various factors including autoimmune diseases like multiple sclerosis (MS).
• B cells, initially overlooked, are now understood to play a significant role in the pathogenesis of neuroinflammatory disorders.

Purpose of the Study:

• To review the literature on the evolving understanding of B cell involvement in neuroinflammation.
• To explore the multifaceted roles of B cells in autoimmune and infectious neuroinflammatory conditions, particularly MS and CNS viral infections.

Main Methods:

• Literature review focusing on B cell functions in neuroinflammation.
• Analysis of B cell contributions beyond antibody production, including antigen presentation and cytokine release.

Main Results:

• B cells exhibit diverse functions in neuroinflammation, including antigen presentation and cytokine production, influencing disease progression.
• B cell interactions can either exacerbate or ameliorate neuroinflammation, depending on the specific disease context.

Conclusions:

• The precise roles of B cells in neuroinflammation are complex and not fully elucidated, with potential functional plasticity.
• Further research into B cell involvement in neuroinflammation is essential for advancing therapeutic strategies for CNS disorders.
