Iron accumulation and α‐synuclein aggregates (e.g., Lewy bodies) have been linked with the pathogenesis of Parkinson's disease (PD), with yet‐to‐be‐determined interaction. Previous studies have indicated that iron binds to α‐synuclein and triggers its aggregation in vitro, and iron is found enriched in Lewy bodies. In the current study, Joppe et al. have found that the propagation of pathological α‐synuclein caused by intrastriatal α‐synuclein preformed fibrils (PFFs) injection was unexpectedly attenuated in rodent brains in a model of brain iron elevation (neonatal iron feeding). PFFs stimulated microglial activation was also reduced in mice with elevated iron. These results may provide new insight into the complex interaction between these two key pathologies of PD.
