The infection of A549 and SK-OV-3 with HAdV26 induced changes in the expression of the IL-6, IL-8, IL-1β, and TNF-α genes; namely the expression of all four genes was increased in HAdV26-infected A549 cells, while HAdV26 infection resulted in increased expression of IL-6 and TNF-α in SK-OV-3 cells. Here, CXCL8 is linked to infection.
