Fig. 4: B cell reconstitution after gene therapy.

a, Switched memory B cell subsets over time. b, IgG production in patients who discontinued intravenous immunoglobulin replacement therapy. Age-matched reference values are indicated by the gray lines (solid line, lower value; dashed line, upper value). c, WASp expression (mean fluorescence intensity (MFI) in arbitrary units) in switched memory, marginal zone and naive B cell subsets in patients (P) and healthy donors (HD7–HD11). d, The VCN in memory B cell (CD27+) and naive B cell (CD27−) subsets (n = 3 biologically independent samples). Data are presented as the mean ± s.e.m.
