A, Flow cytometry for TIL from mice whose TC1 tumors either responded (partial regression) or did not respond (progressive growth) after treatment with the 3 mAb combination plus cisplatin. B, Enlarged spleen and increased CD11b+Gr1+ and IDO+ cells in spleen from a mouse with recurrent tumor compared with a cured mouse. C, Increased expression of arginase and reversed M1/M2 response in the spleen of a mouse with recurrent tumor. mAb indicates monoclonal antibody; TIL, tumor-infiltrating lymphoid cells.
