Using cryo-ET, CRN Team Reck-Peterson showed that full-length LRRK2 can oligomerize on microtubules in its autoinhibited state. Both WT-LRRK2 and PD-linked LRRK2 mutants formed filaments on microtubules.

Congratulations to Amanda Bentley-DeSousa on the publication of her paper that defines how multiple lysosome stresses are integrated by the process known as CASM to activate LRRK2 signaling from lysosomes!!!

Here’s our new review on: LRRK2, Lysosome Damage and Parkinson’s Disease

By knowing when, where and how LRRK2 kinase activity is turned on, we can better understand the relationship between excessive LRRK2 activity and Parkinson’s disease!

Happy to share our new work on LRRK2 and PINK1 signalling in the brain. The two kinases appear to work on parallel pathway, but both converging on cilia. PINK1 KO animals have shorter and fewer cilia in striatal cholinergic interneurons and less GDNF.

Knockout of the LRRK2-counteracting RAB phosphatase PPM1H disrupts axonal autophagy and exacerbates alpha-synuclein aggregation
Fricke et al. find that knockout of the RAB phosphatase PPM1H disrupts axonal autophagosome transport, impairs autophagosomal degradation of axonal α-synuclein, and exacerbates PFF-seeded α-synuclein aggregation in a LRRK2-dependent manner, linking dysregulation of the LRRK2-pRAB-PPM1H axis to defective axonal autophagy and α-synuclein pathology.
