Staphylococcal serine protease-like proteins are pacemakers of allergic airway reactions to Staphylococcus aureus.

Abstract

A substantial subgroup of asthmatic patients have "nonallergic" or idiopathic asthma, which often takes a severe course and is difficult to treat. The cause might be allergic reactions to the gram-positive pathogen Staphylococcus aureus, a frequent colonizer of the upper airways. However, the driving allergens of S aureus have remained elusive.
