hematopoietic system
• antibody-stimulated T cells fail to grow and proliferate and fewer mutant T cells are viable following stimulation (14% compared to 35% of wild-type T cells)
• addition of exogenous IL-2 restores T cell proliferation
|
• no B220+ IgM+ CD5+ B cells are found in the peritoneum
|
• mitogen-induced proliferation is impaired and addition of exogenous IL-2 does not restore proliferation
|
• levels of IgA are below detection in 7 out of 9 nave homozygotes
|
• levels of IgG2b and IgG3 isotypes are below detection and levels of IgG1 and IgG2a are reduced to 36-40% of wild-type
|
• levels of IgM are below detection
|
