Abstract

Good syndrome is an immunodeficiency presenting with thymoma, hypogammaglobulinemia and almost absent B cells. To investigate the origin of the B-cell lymphopenia in these patients, we studied B cell differentiation in the bone marrow of Good syndrome patients. We found very low numbers of precursor B cells in bone marrow of Good syndrome patients and a differentiation arrest after the pro-B-cell stage; this is different from other agammaglobulinemia patients with a defect in pre B-cell receptor signaling.
