OVA-specific antibodies in TCRδ^−/− mice. a–h Serum and fecal (secretory IgA) OVA-specific total IgG (a), IgM (b), IgA (c), secretory IgA (sIgA; d), IgG1 (e), IgG2b (f), IgG3 (g), and IgE (h) from WT, TCRβ^−/−, and TCRδ^−/− mice 21 days after s.c. immunization with either OVA + CFA or OVA + Alum. Mice received a boost of OVA 14 days after immunization (n = 5–10 mice/group). These data are representative of three independent experiments. Data are shown as mean + SEM. One-way ANOVA was used. NS non-significant, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
