IL13 and allergic disease: Since the lung allergy module, including Il4, Il5, and Il13 genes, (L26) was not preserved in blood of HDM allergen-challenged mice (Figs. 2a, b and 3a, c), we tested this module in the lungs (BAL) and blood from an alternative nasal sensitization mouse model of allergy to HDM (also, alternative vivarium CML, WB Imperial College)41, where similarly the Allergy module L26 was detected in BAL but not blood (Supplementary Fig. 8; Supplementary Data 10).
