Th1 and proinflammatory cytokine production following viral vector transduction. DCs that were either unstimulated (iDCs) or activated (mDCs) were transduced with various viral vectors (MOI 500) on day 5 or untransduced and the supernatants collected on day 10. The levels of IL-1β, IL-6, IL-8, IL-12, TNF-α, and IFN-γ were determined using ELISA. The results are the mean of triplicate wells plus or minus the standard deviation (SD).
