Viral subversion of B-cell tolerance: mechanisms linking infection to autoimmunity.

Viral infections can promote B-cell tolerance breakdown through shared immune mechanisms, increasing autoreactive B-cell survival and activation across diverse infection types.

• Why it matters: Understanding how viruses trigger autoimmunity is crucial because it reveals common pathways that could be targeted to prevent or treat autoimmune diseases linked to infections.
• What they did: The authors review mechanistic and clinical evidence from systemic, localized, and neurotropic viral infections, proposing a unifying framework that emphasizes immunological and anatomical contexts over viral identity.
• The result: This framework highlights conserved principles of post-viral autoimmunity, offering a foundation for developing therapies aimed at preserving B-cell tolerance and preventing autoimmune outcomes.
