DCs from tumours or tumour-draining LNs from Y27632-treated mice increased T cell activation, as assessed by IFN-γ production, whereas macrophages did not (Fig. 4d, e); co-culture with DCs from Y27632-treated mice also increased the number of IFN-γ-producing CD8+ T cells (Fig. 4f). Here, IFNG is linked to neoplasm.
