abstractText | 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. |
