Overview
- This week at the FENS Forum, researchers presented analyses of post‑mortem brain tissue showing shared cellular stress responses in Parkinson's disease alongside sex-specific gene activity in astrocytes and oligodendrocytes.
- The team measured gene expression in 73 people with Parkinson's (28 women, 45 men) and 24 controls and found mitochondria‑related genes in astrocytes and myelin‑related genes in oligodendrocytes varied by sex.
- Across five brain regions, affected cells in all samples switched on chaperone proteins that help fold damaged proteins, indicating a common stress response that coexists with the sex differences.
- The authors stressed the results are preliminary because of small sample sizes and said the findings support coordinated, sex‑stratified research such as the DFG Priority Programme 'SEX and GLIA' planned for autumn 2026.
- If replicated, the work could change study design and clinical care by urging separate analysis of male and female data, which may improve prediction, monitoring and tailored treatments for people with Parkinson's.
