We compared TAMs (CD45+7AAD−CD11b+classII+Gr1−, population I in Fig. 2B) from untreated or CD4-treated mice 12 days after tumor challenge and 7 days after T-cell transfer, which is one day after the first CD4 T cells arrive at the tumor site (Supplementary Fig. S3). Here, PTPRC is linked to neoplasm.
