University of Pittsburgh researchers uncovered a surprising link between Alzheimer's disease and herpes simplex virus-1 (HSV-1), suggesting that viral infections may play a role in the disease. The study results are published today in Cell Reports.

The study also revealed how tau protein, often viewed as harmful in Alzheimer's, might initially protect the brain from the virus but contribute to brain damage later. These findings could lead to new treatments targeting infections and the brain's immune response.
"Our study challenges the conventional view of tau as solely harmful, showing that it may initially act as part of the brain's immune defense," said Or Shemesh, Ph.D. Findings emphasize complex interplay between infections, immune responses & neurodegeneration =>targets for therapeutic development.
HSV-1 infection could modulate levels of brain tau protein and regulate its function, a protective mechanism that seemed to decrease post-infection death of human neurons.
