Theoharides, Mast Cells, Autism, Inflammation

Dr. Theoharides at Tufts University

The research focuses on the secretory mechanism and pathophysiological actions of mast cells. Diseases investigated include: atopic dermatitis, arthritis, autism, coronary artery inflammation, interstitial cystitis, migraines and multiple sclerosis. These diseases worsen by stress and we have identified that mast cells both contain and respond to stress hormones. The techniques used include molecular biology, cell biology, and various microscopic techniques, as well as animal models for the target diseases in which mast cells are involved.
