Can boosting early immune signals stop the body from attacking its own nerves?

Original Title

The innate immune response affects the development of the autoimmune response in Theiler’s virus- induced demyelinating disease

Summary

Scientists gave mice a virus that causes nerve damage, then gave some mice a special immune signal (IFN-β) or a fake virus signal (poly(I:C)) right after infection. Other mice got nothing or a blocker for that signal.

Proposed Mechanism
IFNβ enhances anti-inflammatory response and suppresses autoimmune demyelination
Verified
PolyI:C mimics viral RNA to activate innate immunity and suppress autoimmunity via IFNβ-dependent pathways
Verified
Deficient IFNβ during innate response exacerbates autoimmunity by impairing IL-10 and increasing CNS inflammation

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
