CD19 and cancer: Infiltration of F4/80+ tumor-associated macrophages (TAMs), expressing Adgre1, and CD11c+ monocytes/DCs, expressing Itgax, were more abundant after monotherapy with TCRTAG cells, whereas frequencies of cancer-associated fibroblasts (CAFs) expressing Fap, B cells expressing Cd19, and NK cells expressing Klrb1c were comparable across all analyzed groups.
