Fig. 3From: Combination treatment with hypofractionated radiotherapy plus IL-2/anti-IL-2 complexes and its theranostic evaluationhRT/IL-2c combination treatment dramatically enhances tumor-specific CD8+ T cells in secondary lymphatic organs in the C51 colon carcinoma model. Mice bearing an s.c. C51 colon carcinoma tumor were treated with hRT alone or hRT followed by daily i.p. injections of IL-2 or IL-2c for five consecutive days. One day later, IFN-γ- and TNF-α-producing tumor-specific CD8+ cells from tumor (a), spleen (b), and lymph nodes (c) were quantified after restimulation on gp70 peptide-pulsed cells. d Flow cytometry results showing proportions of IFN-γ + CD8+ T cells and TNF-α + CD8+ T cells from tumor, spleen, and lymph nodesBack to article page
