CD4 and neoplasm: Furthermore, we also monitored tumor growth, injection of CD4+ TLEX-CD8086 cells notably inhibited tumor growth compared to injection with other agents, as shown in Figure 6C, at day17, the median tumor volume of mice immunized with CD4+ T LEX-CD8086 cell was 1209 mm3, which was significantly smaller than that of mice immunized with CD4+ TLEX-null cell (2048 mm3), LEX-CD8086 (2290 mm3), LEX-null (2653 mm3) and control groups.
