Cytokines protein percentages of changes in MDCK culture supernatants at 48 h treatment

Treatment	IL-6% change to H1N1	CCL-2% change to H1N1	IFN-β % change to H1N1
Co-pen	−76.659	− 52.488	− 10.511
Pre-pen	− 49.937	−22.761	4.955
Post-pen	−45.553	−10.607	−5.706

Percentages of cytokines changes compared to H1N1, as determined by ELISA, are expressed as pg/ml (N = 2) for 48 h incubation time
