IL-6 Deficiency Worsened Parkinson’s Mouse Models, Especially in Females

A 2026 mouse study found that complete IL-6 deficiency worsened motor dysfunction and dopaminergic injury in MPTP and alpha-synuclein A53T Parkinson’s disease models, with earlier and broader vulnerability in female knockout mice.1 The result cuts against a simple “less inflammation is always better” frame: recombinant IL-6 partly improved MPTP-induced motor dysfunction and striatal dopaminergic terminal …

Chlorpyrifos Exposure Linked to Up to 174% Higher Parkinson’s Risk

A human, mouse, and zebrafish study linked long-term chlorpyrifos exposure to Parkinson’s disease risk, with the strongest exposure-duration estimate reaching OR 2.74 for workplace proximity across the 1974-to-index-year window.1 The paper is stronger than a single epidemiology result because animal experiments pointed to dopaminergic neuron loss, microglial activation, pathological α-synuclein, and autophagy dysfunction.
