♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

premature death ( J:64286 )

• ~38% of mice die within 8 months of birth, compared to 12% of wild-type mice; females often die after giving birth

• despite normal CTL activity toward LCMV infection, and virus clearance, mice die or are moribund within 4 weeks of infection, compared to infected wild-type or Irf1-deficient mice or uninfected controls which remain healthy more than 1 month after infection

immune system

immune system phenotype ( J:64286 )

• mice have normal numbers of CD8+ T lymphocytes in peripheral blood, lymph node, and spleen

• in response to LCMV infection, mice show normal CTL (cytotoxic T lymphocyte) activity and virus is cleared by 15 days after infection

• humoral response to vesicular stomatitis virus challenge is normal; kinetics of immunoglobulin class switching and antibody levels are comparable to wild-type mice

decreased mature B cell number ( J:64286 )

• bone marrow contains only 30-70% of wild-type number of mature B cells (B220^high/surface IgM (sIgM)-positive cells)

decreased T cell number ( J:64286 )

• in bone marrow, number of Thy-1-positive T cells is reduced to 20-50% of wild-type and heterozygous mice; these are considered to be mature TCR alpha-beta positive T cells

abnormal immune system physiology ( J:64286 )

• some nonspecific cytotoxicity is detected

decreased B cell proliferation ( J:64286 )

• bone marrow cells show a dramatic decrease in colony formation in vitro (70% reduction compared to wild-type cells) in response to LPS, a B cell mitogen; splenocytes show a 30% reduction in colony formation in response to LPS

• reduced colony formation (by 40%) by bone marrow cells is seen in response to Il3, Il7 and CSF1 indicating that responses of multipotential progenitors, pre-B cells and macrophages in bone marrow are altered

decreased IgG2a level ( J:64286 )

• serum IgG2a levels are significantly reduced

abnormal response to infection ( J:64286 )

hematopoietic system

decreased B cell proliferation ( J:64286 )

decreased mature B cell number ( J:64286 )

• bone marrow contains only 30-70% of wild-type number of mature B cells (B220^high/surface IgM (sIgM)-positive cells)

decreased T cell number ( J:64286 )

• in bone marrow, number of Thy-1-positive T cells is reduced to 20-50% of wild-type and heterozygous mice; these are considered to be mature TCR alpha-beta positive T cells

decreased IgG2a level ( J:64286 )

• serum IgG2a levels are significantly reduced

integument

skin lesions ( J:64286 )

• older animals exhibit erosions and ulcers around the neck, back and abdomen; in severe cases, patchy scars and postinflammatory hair loss can result

cellular

decreased B cell proliferation ( J:64286 )

immune system

increased memory T cell number ( J:66034 )

• activated/memory CD8+ T cells become more prominent in the spleen after 3 months and after 5 months their percentage exceeds 80%

lymph node hyperplasia ( J:66034 )

• inguinal lymph nodes have 3 times the number of cells as do wild-type and heterozygous littermates as the disease progresses

enlarged inguinal lymph nodes ( J:66034 )

• as skin diseases advances, draining lymph nodes become enlarged

dermatitis ( J:66034 )

• signs of progressive cutaneous inflammation begin as early as 8 weeks of age

hematopoietic system

increased memory T cell number ( J:66034 )

• activated/memory CD8+ T cells become more prominent in the spleen after 3 months and after 5 months their percentage exceeds 80%

integument

dermatitis ( J:66034 )

• signs of progressive cutaneous inflammation begin as early as 8 weeks of age

premature hair loss ( J:66034 )

• hair loss begins as early as 8 weeks of age and eventually extends over the entire trunk

thick epidermis ( J:66034 )

• thickening of the epidermis results from proliferation of keratinocytes in the basal epidermis

reddish skin ( J:66034 )

• homozygotes develop erythema as early as 8 weeks of age

skin lesions ( J:66034 )

• skin lesions occur, and excoriation of lesions results in ulcer formation eventually

skin fibrosis ( J:66034 )

• below the epidermis disorganization of the muscle layer and associated prominent fibrosis is seen
