Chemotactic and Phagocytic Activity of Blood Neutrophils in Allergic Asthma.

Allergic asthma is a chronic inflammatory airway disease, and has been considered a T helper-2-biased response. Studies suggest that neutrophils may be associated with exacerbation and asthma severity. We sought to evaluate the chemotactic activity and phagocytic capacity by peripheral blood neutrophils from individuals with controlled and uncontrolled allergic asthma, and compare the results with non-asthmatic controls groups.
