No difference in cytokine production was noted for HVECs at 24 h post-infection and only a mild induction of MIF and IL-1rα was observed in HCK cells infected with serovar D. Interestingly, a ~1.5–2-fold decrease in IL-1β production was noted in human foreskin keratinocytes at 24 h regardless of the serovar, whereas IL-β production was elevated in L2 and A infected cells at 48 h (Figure 4). Here, IL1B is linked to infection.
