Lymphocytes were isolated from spleens of naïve DO11.10 Tg mice.
Cultured supernatants from cells stimulated in vitro with designated concentrations of Ags were analyzed by cytokine ELISA.
cells were cultured with or without Ag for 24 or 72 hours.
Cytokine concentration was measured in triplicates and is depicted as an average ± SEM. Presented cytokine concentration is corrected over the cytokine production by unstimulated cells.
Statistical significance was calculated by Student’s t test;
p ≤ 0.001
p < 0.05 for the differences between cells stimulated with OVA vs. OVA-pσ1, pσ1 or OVA + pσ1 - stimulated cells, for each time point.
