In the pathogenesis of bronchial asthma, an array of innate and adaptive immune cells is involved including T lymphocytes, eosinophils, basophils, mast cells, bronchial epithelial cells and others. Typically these asthma pathways are associated with eosinophilia and an obvious Th2 cell phenotype that hallmarks most endotypes.
