Dendritic cells are cells specialized for antigen capture, migration a
nd T cell stimulation. Recent advances have been made in understanding
their origin, their heterogeneity, the mechanism of antigen uptake, a
nd the signals that induce their migration and maturation into immunos
timulatory antigen-presenting cells. Dendritic cells represent the nat
ural adjuvants for T cell responses and their therapeutic exploitation
in the near future is foreseen.
