ACML-55 treatment increases the number of NK and γδ T cells. Sex- and age- matched BALB/c mice were administered orally with 2 mg/mL (200 μL/mouse) ACML-55 or equivalent volume of PBS daily (n = 5 for each group) for fourteen days, followed by inoculation with CT26 tumor cells intraperitoneally. Ten days post-inoculation, splenocytes were used for analysis of NK, NKT, αβ, and γδ T cells. A: The percentage of NK and γδ T cells (mean ± SD) is shown (P < 0.05); B: An example of the FACS analysis is given.
