Similarly, mice with subcutaneous and liver tumors treated with RT, anti-PD-L1, or the combination of both were found to exhibit significantly higher T cell infiltration within the subcutaneous tumor in the combination group, while T cell levels did not increase in the anti-PD-L1 group, and RT alone was not sufficient to modulate the amount of T cells by itself. The gene discussed is CD274; the disease is neoplasm.
