TMEV Viral Parkinson’s Mouse Model Caused 20-Week Dopamine-Lesion Behaviors
A 2026 mouse study found that Theiler’s murine encephalomyelitis virus (TMEV) injected into the substantia nigra produced persistent Parkinson’s-like motor signals through 20 weeks, including apomorphine-induced rotations at every measured post-injection timepoint.1 The finding makes TMEV a useful viral-neuroinflammation model of dopamine-neuron injury, but it does not show that Theiler’s virus causes human Parkinson’s disease. …
