Treatments of IPEC-J2 Cells

Name	Scope	Treatment
Experiment 1	Evaluation of IFN-α effects on oxidative stress.	Pretreatment of IPEC-J2 cells with different concentrations of IFN-α. After 2 h of incubation, wash, and induction of oxidative stress.
Experiment 2	Evaluation of IFN-α effects on inflammatory responses.	Treatment of IPEC-J2 cells with different concentrations of LPS and/or IFN-α at 1 or 100 U/mL.
Experiment 3	Evaluation of the ability of IFN-α to amplify lymphoid cell signals.	Treatment of IPEC-J2 cells with supernatants obtained after tonsil cell treatment with IFN-α at 1 or 100 U/mL.
