LRRK2 mutations are the most common genetic cause of Parkinson’s disease, but its normal physiological role in the brain is unclear. Here we show that inactivation of LRRK2 and its functional homologue LRRK1 results in earlier mortality and age-dependent, selective neurodegeneration. Loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc) and noradrenergic neurons in the locus coeruleus is accompanied with increases in apoptosis, whereas the cerebral cortex and cerebellum are unaffected. Furthermore, selective age-dependent neurodegeneration is only present in LRRK−/− but not LRRK1−/− or LRRK2−/− brains, and is accompanied with increases of α-synuclein and impairment of the autophagy-lysosomal pathway. Quantitative electron microscopy analysis revealed age-dependent increases of autophagic vacuoles in the SNpc of LRRK−/− mice before the onset of dopaminergic neuron loss. These findings revealed an essential role of LRRK in the survival of dopaminergic neurons and the regulation of the autophagy-lysosomal pathway in the aging brain.
