hematopoietic system
• B cell numbers and differentiation normal in bone marrow
• defect in terminal differentiation of mature B cells
• enhanced cell death in B cells but not T cells
|
• peritoneal CD5+ B1 cells are absent
|
• reduced numbers of natural killer cells in spleen
|
• response to T-cell independent antigens abolished
|
• B cell proliferation in the spleen markedly impaired
|
• undetectable
|
• reduced levels of IgG1, IgG2a, IgGb, IgG3
|
• impaired response to T-cell dependent antigen
• antigen mediated T-cell activation decreased dramatically
