In support of our genetic results, we found that overexpression of LRRK2 IT led to a significant enhancement of pMad accumulation in the nuclei of glia surrounding DA neurons but not in DA neurons themselves ( Figures 5L–5N ). Similarly, we found that pMad accumulation in glial cells showed a strong trend toward enhancement (15% increase in mean pMad fluorescence intensity; p = 0.069) as a result of exposure to paraquat.
