RENBP and neoplasm: Adding fluorescently labelled OVA to 3LL-R tumour single-cell suspensions for 15 min at 4 and 37 °C (active Ag uptake) revealed that all TADC subsets were able to ingest OVA at 37 °C (Fig. 4a), but that Mo-DCs again showed a higher Ag uptake capacity compared with both cDC types (Fig. 4b).
