Activating mutations in the cytoskeletal regulator Wiskott-Aldrich syndrome protein (WASp) cause X-linked neutropenia (XLN) with reduced serum level of IgA. Objective: We investigated the role of B cells in XLN pathogenesis. Methods: We examined B cells from 6 XLN patients, 2 of whom had novel R268W and S271F mutations in WASp. By using immunized XLN mouse models that carry the corresponding patient mutations, WASp L272P or WASp I296T, we examined the B-cell response. Results: XLN patients had normal naive B cells and plasmablasts, but reduced IgA1 B cells and memory B cells, and poor B-cell proliferation. On immunization, XLN mice had a 2-fold reduction in germinal center B cells in spleen, but with increased generation of plasmablasts and plasma cells. In vitro, XLN B cells showed reduced immunoglobulin class switching and aberrant cell division as well as increased production of immunoglobulin-switched plasma cells. Conclusions: Overactive WASp predisposes B cells for premature differentiation into plasma cells at the expense of cell proliferation and immunoglobulin class switching.
