DUSP26 and Parkinson disease: Because L-DOPA has been shown to be highly effective in the alleviation of motor disabilities in animal models of PD and PD (Navailles et al., 2010, 2014; Nevalainen et al., 2014; De Deurwaerdère et al., 2017), our results suggest that the motor deficits induced by lead and DSP-4 correspond to atypical Parkinsonism.
