Interestingly, miR-205 prevented neurite outgrowth defects in neurons expressing PD-related LRRK2 R1441G mutants (Cho et al., 2013), thus suggesting that this miRNA can protect the progression of PD due to LRRK2 genetic susceptibility, which may be a potential therapeutic approach in LRRK2 PD patients. Here, LRRK2 is linked to Parkinson disease.
