NFKBIA and infection: Our western blot data showing increased IκBα phosphorylation after PRRSV infection in Marc-145 cells (Fig. 3D) is in line with previous report in PAMs challenged with PRRSV or in CRL2843 cells transfected with N protein expression vector31, where phosphorylation of IκBa was observed already 30 minutes post infection or 24 hours post transfection.
