    Genetically influenced B-cell gene expression may contribute to peripheral immune dysregulation in Parkinson's disease.

  • 2

    Eight high-confidence Mendelian randomization causal genes were identified, including five risk-increasing and three protective genes.

  • 3

    Exploratory analysis suggested early expression changes in specific genes detectable in early-stage Parkinson's disease.

  • 4

    CellChat analysis indicated increased communication probability in the MIF signaling pathway from healthy controls to late-stage Parkinson's.

  • 5

    CD74, IL2RA, and CR1 were nominated as candidate therapeutic targets for future validation based on computational findings.
