Figure 2.
Modest deficit in peripheral B cells of CBPflox/flox;CD19+/Cre and p300flox/flox;CD19+/Cre mice. The number of B cells and T cells per mL of peripheral blood for CBPflox/flox;CD19+/Cre (A) and p300flox/flox;CD19+/Cre (B) mice and controls. Number of mice of each genotype is indicated. Mean ± SEM. (C) Representative flow cytometric analysis using anti-IgM and anti-IgD antibodies and splenic lymphocytes from CD19+/Cre, CBPflox/flox;CD19+/Cre, and p300flox/flox;CD19+/Cre mice. Percentage of total splenic lymphocytes representing the major B-cell subtypes (IgMhi IgDlo, IgMhi IgDhi, IgMlo IgDhi). (D-E) Quantification of IgM and IgD flow cytometry data as in panel C for the indicated number of mice of each genotype (mean ± SEM). Flow cytometric analysis and complete blood count analyses for the CBPflox and p300flox groups were performed at different times and may not be directly comparable to each other.
