Research Overview

We study cell-cell and cell-extracellular matrix interactions in the airway to understand the fundamental mechanisms that regulate airway caliber and why they fail in diseases like asthma.

Asthma affects over 40 million people in the United States and 300 million worldwide1. In the US alone, the health care cost of asthma exceeds 80 billion dollars annually2. Despite its prevalence and cost burden, treatment for this disease has seen very little change over 50 years. The current therapeutic standard, which targets airway smooth muscle force and airway inflammation, aims to prevent the recurrence of symptoms and does not stop the decline in lung function. In severe asthma, current therapies fail in providing any relief to the patient3. This suggests that there are mechanisms at play that are insensitive to current asthma therapies but predominant, nonetheless.

Research from our lab has revealed that pathological changes occurring in the extracellular matrix ( a meshwork of collagen, enzymes, and proteins that surrounds and supports cells in tissue) can drive healthy human airway smooth muscle cells to become hypercontractile, as seen in asthma.
