Antigen uptake, processing and presentation by dendritic cells [DCs] have become amenable to cell biological approaches. The critical events occur in DCs that are undergoing maturation in response to inflammatory stimuli. Successful antigen presentation can be monitored directly using antibodies that are specific for particular MHC-peptide complexes. What a contrast to earlier times when it was difficult to visualize even the uptake of antigen into isolated DCs and DCs in the T cell areas of lymphoid organs! We emphasize here the efficiency of antigen capture and presentation by maturing DCs, especially for dying cells. This presentation of cellular antigens by DCs likely explains the phenomenon of cross priming in the setting of transplantation and other clinical states.
