Genes included IL15, IL15RA, C2, IL1RN, CCL22, PSMD family members, TAP1/2, TNFAIP3, and TRAF2/TRAF4. Gene expression differences between BECs that were and were not preconditioned with IL-13 were most prominent at later time points after viral infection. This evidence concerns the gene IL1RN and viral infectious disease.
