Hardy, Carmen Fernández, Adrian J. Thrasher, and Eva Severinson From the Department of Cell and Molecular Biology, Medical Nobel Institute, Karolinska Institutet, Stockholm, Sweden; the Institute of Child Health, University College London, London, United Kingdom; and the Department of Immunology, The Wenner-Gren Institute, Stockholm University, Stockholm, Sweden. The Wiskott-Aldrich syndrome protein (WASp) is mutated in the severe immunodeficiency disease Wiskott-Aldrich syndrome (WAS). The function of B cells and the physiologic alterations in WAS remain unclear. We show that B cells from WAS patients exhibited decreased motility and had reduced capacity to migrate, adhere homotypically, and form long protrusions after in vitro culture. WASp-deficient murine B cells also migrated less well to chemokines. Upon antigen challenge, WASp-deficient mice mounted a reduced and delayed humoral immune response to both T-cell–dependent and –independent antigens. This was at least in part due to deficient migration and homing of B cells. In addition, the germinal center reaction was reduced in WASp-deficient mice. Thus, WASp is crucial for optimal B-cell responses and plays a pivotal role in the primary humoral immune response.
