Cell Biology of Steroid Resistant Asthma

Completed · Not applicable

Conditions studied: Asthma

In brief

The hypothesis is that patients who demonstrate steroid resistant asthma by showing little or no improvement in lung function after a course of oral steroids have different cellular responses to steroids than patients who are steroid sensitive. These altered responses are the reason they demonstrate steroid resistance.
