RAG2 and neoplasm: To test the relative contribution of cross-presenting cDC1s and cross-dressed inflammatory monocytes to T cell restimulation, we injected NTT and NTTB2m KO tumours, which abolishes the ability of inflammatory monocytes to present tumour antigens through MHCI cross-dressing, into Rag2–/– mice and Rag2–/–Batf3–/– mice and performed ACT (Fig. 2g).
