Exploring T Cell Roles in Parkinson's Disease with Dr. Arlehamn
In this enlightening episode, we are joined by Dr. Arlehamn as we delve into the complex world of Parkinson's Disease (PD), a multi-stage neurodegenerative disorder with largely unknown causes. Recently, T cells have been identified to play a significant role in the autoimmune features associated with PD.
Dr. Arlehamn takes us through his team's cutting-edge research that involves RNA sequencing on PBMC and peripheral CD4 and CD8 memory T cell subsets derived from PD patients and age-matched healthy controls. When these groups were stratified by their T cell responsiveness to alpha-synuclein (α-syn), the study revealed a broad differential gene expression profile in memory T cell subsets and a specific PD associated gene signature.
Notably, this investigation led to the identification of significant enrichment of transcriptomic signatures previously associated with PD, including those for oxidative stress, phosphorylation, autophagy of mitochondria, cholesterol metabolism, inflammation, and the chemokine signaling proteins CX3CR1, CCR5, and CCR1. Moreover, the team identified genes in these peripheral cells that have previously been shown to be involved in PD pathogenesis and expressed in neurons, such as LRRK2, LAMP3, and aquaporin.
Together, these findings suggest that characteristics of circulating T cells with α-syn-specific responses in PD patients provide valuable insights into the interactive processes occurring during PD pathogenesis. This episode is a deep dive into the advanced research around PD, its autoimmune aspects, and the potential targets for intervention. Whether you're a neurology enthusiast or someone interested in understanding the mechanisms behind neurodegenerative diseases, this episode promises to be a highly informative and intriguing conversation.
