Blocking of airways in asthma patients explained

Houston Methodist researchers have found that a particular class of white blood cells, called T helper cells, overstimulate the production of a sticky protein, mucin, which cloggs up the airways. Mucin protects the surface of the airways, but excessive secretion of mucin, as seen in asthma, is damaging. Now that scientists have resolved the molecular mechanism of T helper cell activation and mucin secretion, new drugs for asthma may be developed that are completely different from the steroids that are being used today.
