This research explores how immune-related cells and molecules, beneficial in wound healing, may become harmful in Parkinson’s disease. Using the fruit fly as a model organism, the study investigates which inflammatory processes contribute to brain damage. Early results suggest that excessive activation worsens degeneration, offering potential targets for future therapies.

This research investigates how T cells influence microglial behavior in Alzheimer’s disease. Using a mouse model, the study found that removing T cells did not alter amyloid-beta plaques but unexpectedly led to healthier microglial activity and reduced myelin damage. The findings suggest T cells may worsen neurodegeneration and reveal new therapeutic avenues.
