Quantitative real-time RT-PCR performed to measure IL-8 mRNA levels in HAdV-19 infected cells showed a 5-fold increase in IL-8 mRNA compared to mock-infected cells but only a 0.7-fold change in cells treated with 20 μM SB203580 prior to infection with HAdV-19 (data not shown). The gene discussed is CXCL8; the disease is infection.
