The percentages of CD4+ and CD8+ T cells in the abscopal tumor were both increased in mice presenting significant abscopal effect following MWA compared with the abscopal effect group (Figure 5E), while only mice exhibiting significant abscopal effect showed higher percentages of intratumoral CD4+ T cells than the control group (p < 0.001, Figure 5E). Here, CD8A is linked to neoplasm.
