FHA stimulates DCs to direct naive T cells to a Tr1 subtype. OVA-specific CD4+ T cell lines were generated in vitro by stimulating purified naive T cells from DO11.10 TCR Tg mice with DCs preincubated for 24 h with OVA peptide (0, 0.5, 5, 50 μg/ml) and FHA (5 μg/ml), CpG-ODN (1 μg/ml), FHA, and anti–IL-10 (10 μg/ml) or medium only. After two rounds of antigen stimulation supernatants were removed and concentrations of cytokines determined by immunoassay. Results are representative of two experiments.
