Next, the population of effector/memory T lymphocytes (Tem; CD3+CD8+CD44+CD62Llow), hallmarks of adaptive immunity, was assessed in mice that experienced complete tumor regression (CR mice) through 25 mW micro-LED and αPD-L1 to evaluate the establishment of immunological memory that prevents recurrence by previously encountered tumor cells. The gene discussed is CD8A; the disease is neoplasm.
