N	normal phenotype

immune system

decreased eosinophil cell number ( J:113065 )

• following exposure to an antigen, mice exhibit reduced eosinophil infiltration (0.60+/-0.17x10⁵ cells/ml compared to 3.15+/-0.66x10⁵ in wild-type mice)

decreased IgE level ( J:113065 )

• IgE levels are undetectable (less than 10 ng/ml compared to 3300+/-1300 ng/ml in wild-type mice)

decreased interleukin-5 secretion ( J:113065 )

• mice fail to secrete IL-5 after cross-linking of the CD3/TCR complex

hematopoietic system

decreased eosinophil cell number ( J:113065 )

• following exposure to an antigen, mice exhibit reduced eosinophil infiltration (0.60+/-0.17x10⁵ cells/ml compared to 3.15+/-0.66x10⁵ in wild-type mice)

decreased IgE level ( J:113065 )

• IgE levels are undetectable (less than 10 ng/ml compared to 3300+/-1300 ng/ml in wild-type mice)

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

immune system

decreased IgE level ( J:14593 )

• unlike in wild-type mice, IgE levels are undetectable prior to and following immunization

decreased IgG1 level ( J:14593 )

• IgG1 levels are reduced 20-fold compared to in wild-type mice and following immunization IgG1 levels are 12-fold lower than in immunized wild-type mice

• following immunization with DNP-ovalbumin, IgG1 antibodies are 10-fold lower than in wild-type mice

increased IgG level ( J:14593 )

• following infection with N. brasiliensis, IgG2 and IgG3 levels are slightly higher than in wild-type mice

• following immunization with DNP-ovalbumin, IgG2 and IgG3 levels are 100- to 500-fold higher than in wild-type mice

decreased interleukin-10 secretion ( J:14593 )

• stimulated CD4+ T cells in vitro fail to produce IL-10

decreased interleukin-3 secretion ( J:14593 )

• in stimulated CD4+ T cells, the production of IL-3 is reduced more than 70% of wild-type value

decreased interleukin-4 secretion ( J:14593 )

• stimulated CD4+ T cells in vitro fail to produce IL-4

decreased interleukin-5 secretion ( J:14593 )

• stimulated CD4+ T cells in vitro fail to produce IL-5

abnormal response to infection ( J:14593 )

• following infection with N. brasiliensis, CD4+ T cells produce reduced levels of Th2 cytokines, increased levels of interferon-gamma, and reduced blood eosinophilia levels compared to infected wild-type mice

• however, CD8+ T cells do produce IL-5 following infection with N. brasiliensis
