Journal Club – “Parkinson’s disease neurons exhibit alterations…” – Presented by Anahit Campbell

Anahit presents Chen et. al. 2023 “Parkinson’s disease neurons exhibit alterations in mitochondrial quality control proteins” published in npj Parkinson’s Disease on 08 August 2023. The work from Amy Reeves’ team that utilized imaging mass cytometry (IMC) to investigate the role of mitochondrial dysfunction, proteostasis, and quality control in dopaminergic neurons from Parkinson’s patients.
