Using a commercial kit to detect typical Th1/Th2 cytokines, we compared the levels of IFN-γ, TNF-α, IL-2, IL-4, and IL-5 in lung homogenates 14 days after granuloma induction (Figure 6) and in serum samples (Figure 7) collected 1, 5, 14 and 18 days after granuloma induction. Here, IFNG is linked to Granuloma.
