Flow cytometric analysis revealed a significant increase in the absolute count per milligram of the tumor tissue for CD3+ (Figure 5A), CD4+ (Figure 5B), and CD8+ (Figure 5C) T cells along with CD19+ B cells (Figure 5D), natural killer cells (Figure 5E), and M1-like macrophages (Figure 5F) in the CBD-treated mice as compared to the vehicle-treated mice. Here, CD4 is linked to neoplasm.
