Allison Fryer

Allison Fryer, PhD

Professor of Medicine

Dr. Fryer's research has shown that airway hyperreactivity, that is similar to asthma, is accompanied by recruitment of eosinophil inflammatory cells to airway nerves. These eosinophils are activated and release a preformed protein, eosinophil major basic protein, which binds to and blocks M2 muscarinic receptors on nerves. M2 blockade increases neurotransmitter release and increases bronchoconstriction, similar to asthma. Her lab is examining what mechanisms underlie recruitment and activation of eosinophils at the autonomic nerves in the lungs. They are also working to understand how exposure to viral infection, organophosphate pesticides, ozone, or allergens all induce loss of M2 receptor function in the nerves, and the role of eosinophils in the resulting airway hyperreactivity.
