Probiotics also controlled airway hyperresponsiveness, levels of immunoglobulins, eosinophil infiltration to perivascular and bronchoalveolar lavage fluid (BALF), Glutamic pyruvic transaminase, interleukin-17 (IL-17), mucus secretion, Eosinophil peroxidase activity (EPO), and goblet cell hyperplasia. The gene discussed is IL17A; the disease is airway hyperresponsiveness.
