For Poly(I:C) dsRNA treatment experiments, H69ARsgCTRL and H69ARsgMAVS cells were plated in RPMI media, transfected with 0.5 μg/mL
Poly(I:C) HMW (InvivoGen, Sand Diego, CA) using
XtremeGene HP transfection reagent (Sigma-Aldrich, St. Louis, MO) and cultured for 72 hours. On day 3 after transfection, conditioned media was recovered and CXCL10 protein expression was quantified using
Human CXCL10/IP-10 Quantikine ELISA kit (R&D Systems, Minneapolis, MN). RNA was extracted and expression levels of relevant genes were analyzed by qRT-PCR.
