The subsets of memory CD8+ T cells in tumor-draining lymph nodes and tumors are shown in Figure 3B. As expected, the majority of the CD8+ T cells in the tumor-draining lymph nodes are naïve and central memory subsets whereas most of the CD8+ T cells in the tumors are the effector memory subset, indicating the migration of the memory T cells developed in the tumor-draining lymph nodes into the tumor site. Here, CD8A is linked to neoplasm.
