CD44+CD62L− effector phenotype cells were rare among the unconverted CD8 T cells that did not recognize SIY in the TdLN (Fig. 3ci), indicating that a large proportion of the effector populations in the TdLN either emigrated from the tumor to the TdLN or recognize the immunodominant tumor antigen SIY. The gene discussed is CD8A; the disease is neoplasm.
