Asthma is a chronic disease of the airways that may cause wheezing, breathlessness, chest tightness and coughing. According to the U.S. Centers for Disease Control and Prevention (CDC), more than 20 million Americans reported having asthma in 2001, including more than six million children. In 2000, the CDC reported that there were more than 10 million asthma-related outpatient visits to private physician offices and hospital clinics (nearly 5 million of these involved children under 18). The National Institutes of Health (NIH) have estimated asthma-related healthcare costs in the U.S. at $14 billion annually.

About HMGB1

HMGB1, a pro-inflammatory protein secreted by different cell types, is part of the body's response to trauma and infection. HMGB1 is expressed at high levels beginning 12 to 72 hours after an injury, which is about the time inflammation-associated tissue damage begins. Because of the timing and duration of expression of HMGB1, it may be an important factor in the sequence of events that result in severe tissue damage following injury or during chronic inflammation.
