Normal T-dependent and T-independent humoral immunity in IgβKΔR mice. (A) WT (open red circles) or IgβKΔR (open blue squares) mice were immunized with T-independent (NP-Ficoll) or T-dependent (NP-CGG or NP-SRBC) antigens, and sera were assayed for NP-specific IgM antibodies (top) and either low-affinity (middle) or high-affinity (bottom) IgG antibodies by ELISA on the indicated days (each symbol represents assay from one mouse). *, P = 0.002; **, P = 0.001; ***, P = 0.005; †, P = 0.004; ‡, P = 0.05. Horizontal lines represent means. (B and C) WT MD4 or IgβKΔRxMD4 were labeled with CFSE and transferred along with HEL-SRBC into B6.SJL-PtprcaPepcb/BoyJ mice. (B) Spleens were harvested 3 d after transfer and analyzed by flow cytometry (n = 5 each group). (C) Spleens were harvested 6 d after transfer/immunization and analyzed by flow cytometry. Individual mice indicated in bar graph (right). Error bars represent mean ± SD.
