“…5 As in other forms of asthma, inflammatory changes are found in the airways of patients with TDI asthma, along with eosinophils, T cells, and collagen deposition as well as the typical range of cytokines associated with asthma. [6][7][8] When T-cell clones were derived from the airways of patients with TDI asthma, the majority were CD8 + and expressed IL-5 and IFN-γ, 9 suggesting similarities with the T-cell response seen in patients with atopic asthma. 10 However, when patients with TDI asthma underwent bronchial challenge, they showed a more marked neutrophil response 8 than would be expected in corresponding pollen or house dust mite challenges.…”
