Mature TGF-M-DCs are less efficient in induction of allogeneic MLR than mature TGF-GM-DCs. LPS-activated mature TGF-M-DCs and TGF-GM-DCs were stimulated with allogeneic naive CD4+ T cells for 6 days. T-cell proliferation was determined by [methyl-3H]thymidine incorporation assay. Data are representative of 3 independent experiments.
