Pathogenic mutations in leucine\u2010rich repeat kinase 2 (LRRK2) are the most common genetic cause of Parkinson's disease, and several small\u2010molecule LRRK2 kinase inhibitors have been developed, with some in clinical trials. However, the physiological role of endogenous, non\u2010pathogenic LRRK2 remains largely unknown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Experimental Approach<\/jats:title>\n                    <jats:p>LRRK2 expression was examined in murine dorsal root ganglia (DRGs) following sciatic nerve crush (SNC) injury. Regenerative axon growth was assessed using cultured adult DRG neurons after genetic or pharmacological inhibition of LRRK2. Axon regeneration after SNC injury was evaluated in vivo following oral administration of the LRRK2 inhibitors, MLi\u20102 or PF\u201006447475. Axonal trafficking experiments and phosphoproteomic analyses were performed to investigate mechanisms underlying axon growth promotion induced by LRRK2 inhibitors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Results<\/jats:title>\n                    <jats:p>SNC injury reduced LRRK2 expression in DRGs. Genetic and pharmacological inhibition of LRRK2 enhanced regenerative axon growth in culture. Oral administration of MLi\u20102 or PF\u201006447475 promoted axon regeneration in vivo after SNC injury. MLi\u20102 enhanced mitochondrial trafficking, and phosphoproteomic analyses identified cellular processes and kinase\u2010substrate signalling networks associated with a pro\u2010regenerative state triggered by LRRK2 inhibition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion and Implications<\/jats:title>\n                    <jats:p>These findings identify endogenous, non\u2010pathogenic LRRK2 as a suppressor of axon regeneration.
