The induction of CTLs by injection of CDDP and/or HVJ-E/BLM. When tumors were 5 mm in diameter, CDDP was i.p. injected and HVJ-E/BLM was injected on days 1, 6, and 9 after CDDP treatment (CDDP+B/H). On day 10, mice were sacrificed and splenocyte cells were re-stimulated with CT-26 cells for 5 days, and 51Cr release was subsequently assayed. Results are expressed as means (n = 2 per group), representative of two independent experiments. E:T ratio indicates the effector cell to target cell ratio.
