immune system
abnormal B cell differentiation ( J:76990 )
• B cell development and maturation are delayed in young mutants
• impaired transition from pre-B to immature B cells and from immature to mature B cells
• adult mutants exhibit a slower rate of generating mature recirculating B cells
increased immature B cell number ( J:76990 )
• increase in numbers of immature IgM hi B220 lo B cells in the spleens of young mutants
increased pro-B cell number ( J:76990 )
• increase in IgM-IgD- B cells in Peyer's patches and mesenteric lymph nodes
increased B-1 B cell number ( J:76990 )
• B-1 cell numbers are increased in the spleen and peritoneal cavity
increased marginal zone B cell number ( J:76990 )
• modest increase of spleen marginal zone B cells
decreased B cell number ( J:76990 )
• splenic (B220+) B cells are decreased by 24% compared to wild-type; numbers in lymph nodes and Peyer's patches are decreased by 32% and 20%, respectively
decreased mature B cell number ( J:76990 )
• decrease in numbers of mature B cells in the bone marrow and periphery
decreased B-2 B cell number ( J:76990 )
• mature B-2 cell numbers are reduced in the periphery
decreased follicular B cell number ( J:76990 )
• 38% reduction in IgM int CD23+ mature long-lived follicular B cells in the spleen
increased pre-B cell number ( J:76990 )
• increase in the number of IgM-IgD- pre-B cells
abnormal B cell physiology ( J:76990 )
• the increase in intracellular calcium following surface IgM crosslinking is more rapid in mutant B cells than in wild-type B cells
abnormal B cell activation ( J:76990 )
• increase in the number of activated B cells
increased B cell proliferation ( J:76990 )
• splenic B cells show increased proliferative responses to low levels of IgM cross-linking and to stimulation with LPS
increased IgM level ( J:76990 )
• small, but significant, increase in the serum IgM level in nonimmunized mutants
• mutants show normal T-independent responses except for a slightly stronger IgM response to TNP-Ficoll, and normal type 2 T cell-independent responses
