CSL enhances the production IgG1⁺ plasma cells. (A) CD19-Cre-DNMAML1 mice or littermate controls were immunized with NP-CGG and splenocytes analyzed 7 days later. Numbers are the percentage of cells in the gate indicated in parentheses above the plot. Lin⁻ indicates CD3⁻ and Gr-1⁻. Gates were drawn using B6 mice immunized with alum alone or alum+NP-CGG (Figure S3) (B). Numbers represent the percentage of cells in the gate indicated in parentheses above the plot but from a sample stained separately from that presented in panel A.
