When EETs were exogenously injected into a mouse model of asthma, epithelium-derived cytokine levels (including IL-1α, IL-1β, Chemokine ligand 1 [CXCL-1], CCL24, IL-33, and TSLP) were found to be significantly increased in mouse bronchoalveolar lavage fluid (BALF) [11]. Here, IL33 is linked to asthma.
