- Parkinson's Disease (PD) involves degeneration of dopaminergic terminals in the striatum, leading to dopamine depletion and movement control issues.
- The LRRK2-G2019S mutation, highly expressed in the striatum, is a common genetic factor associated with PD.
- Study aimed to compare healthy and PD patient-derived striatum organoids with the LRRK2-G2019S mutation to identify disease-contributing alterations.
- PD striatum organoids showed increased levels of striatum-specific proteins (DRD2, DARPP32, CDK5) and exhibited an inflammatory phenotype.
- Proteomics and kinase activity analysis confirmed the inflammatory phenotype, supported by the presence of reactive astrocytes.
- Findings suggest that PD-relevant phenotypes, including inflammation, can occur in the striatum independently of dopaminergic input.
