♀ | phenotype observed in females |
♂ | phenotype observed in males |
N | normal phenotype |
• decrease in the frequency and absolute number of immature B cells
|
• decrease in the frequency of B1 cells in the peritoneal cavity
|
• increase in B-cell frequencies in spleen, inguinal lymph nodes, and peritoneal cavity
• increase in absolute numbers of B cells
|
• increase in the frequency and absolute number of mature B cells
|
• increase in the frequency of B2 cells in the peritoneal cavity
|
• within the mature B-cell population, marginal zone (MZ) B cells are increased
|
• decrease in T-cell frequencies in spleen, inguinal lymph nodes, and peritoneal cavity
|
• while the reduced frequency of follicular B cells is due to the expansion of MZ cell population, the absolute number of follicular B cells is not reduced, but is even increased
|
• B cells exhibit increased expression of surface molecules (MHCII, CD86, CD23, CD21, and ICOSL) associated with B-cell activation
|
• antibody deposition to kidney glomeruli is seen in 10 month old mice, but not in 8 week old mice
|
• increase in serum and fecal IgA concentration
• increase in frequencies of IgA+ B cells in both the spleen and Peyers patches
|
• increase in serum IgG2a concentration
|
• increase in serum IgG2b concentration
|
• increase in serum IgM concentration
|
• increase in serum IL-6 concentration at 10 months of age
|
• mutant recipient mice transferred with BM12 CD4 T cells show a stronger autoimmune response than wild-type mice, have a higher frequency of germinal center B cells and plasma cells, a higher titer of serum autoantibodies against dsDNA and nuclear antigen, and higher levels of kidney glomerular deposition with IgG
|
• mice develop a lupus-like autoimmune disease
|
• mice exhibit higher concentration of serum autoantibodies against nuclear antigen at 10 months of age
|
• mice exhibit higher concentration of serum autoantibodies against double-stranded DNA (dsDNA) at 10 months of age
|
• decrease in the frequency and absolute number of immature B cells
|
• decrease in the frequency of B1 cells in the peritoneal cavity
|
• increase in B-cell frequencies in spleen, inguinal lymph nodes, and peritoneal cavity
• increase in absolute numbers of B cells
|
• increase in the frequency and absolute number of mature B cells
|
• increase in the frequency of B2 cells in the peritoneal cavity

|
|
|
♀ | phenotype observed in females |
♂ | phenotype observed in males |
N | normal phenotype |
N |
• mice show a rescue of the B-cell defect seen in Otub1 conditional mice, with mice showing enhanced frequency and absolute number of peritoneal B2 cells
• mice show a rescue of the defect in B-cell maturation, with increased splenic mature B cells, particularly the MZ B cells
