IFNG and neoplasm: In the treatment group receiving radiation and/or non-particlized IFN-γ, each treatment (Fig. 4I, K, , , , , ) induced significantly greater CD3+ T-cell infiltration than the untreated group (Fig. 4I: primary tumor, K: pulmonary metastasis) starting at 36 h after treatment initiation (Fig. 4I, K, *, a).Non-particlized IFN-γ alone (Fig. 4I, K, ) and 10-Gy radiation alone (Fig. 4I, K, ) showed nearly equivalent ability to induce CD3+ T-cell infiltration (Fig. 4I, K, b).
