Cytokine secretion and function of mature MoDCs harvested on day 9.

(A) Secretion of IL-12 by mature MoDCs precultured with (▪) or without (■) the addition of 20 μg/mL recombinant β₂M in the first 7 days. (B) ³H-Thymidine incorporation (cpm × 10³) in allogeneic MLR induced by mature MoDCs precultured with (▪) or without (■) the addition of 20 μg/mL recombinant β₂M in the first 7 days. Mean ± SEM of 3 independent experiments. *P < .05; **P < .01.
