LRRK2 Inhibition Mitigates the Neuroinflammation Caused by TLR2-Specific α-Synuclein and Alleviates Neuroinflammation-Derived Dopaminergic Neuronal Loss.

ABSTRACT: Evidence suggests that crosstalk occurs between microglial leucine-rich repeat kinase 2 (LRRK2)-a regulator of neuroinflammation-and neuron-released α-synuclein (αSyn)-a promoter of microglial activation and neuroinflammatory responses-in neuroinflammation-mediated Parkinson's disease (PD) progression. Therefore, we examined whether LRRK2 inhibition reduces the responses of microglia to neuroinflammation caused by neuron-released αSyn. We examined the neuroinflammatory responses provoked by Toll-like receptor 2 (TLR2)-positive αSyn of neuronal cells using an LRRK2 inhibitor in the mouse glioma cells, rat primary microglia, and human microglia cell line; and the effects of LRRK2 inhibitor in the co-culture of ectopic αSyn-expressing human neuroblastoma cells and human microglia cells and in
