immune system
• B cell proliferation in response to anti-IgM is reduced 3- to 4-fold compared to in wild-type mice
• however, B cell proliferation in response to IL-4 alone or in combination with CD40LG or LPS is normal
• T cell proliferation in response to anti-CD3-epsilon is reduced 5- to 8-fold compared to in wild-type mice
• T cell proliferation in response to ovalbmin is reduced 4- to 6-fold compared to in wild-type mice
• however, T cell proliferation in response to PHA is normal
• the number of CD5+ B220+ T cells is slightly decreased (21.0+/-8.6% compared to 39.5+/-9.1% in wild-type mice)
• IgG3 levels are slightly lower than in wild-type mice
• following challenge with ovalbumin, anti-ovalbumin IgG3 antibodies are lower than in similarly treated wild-type mice
• following stimulation with TNP-Ficoll, anti-TNP IgM antibodies are 9-fold lower than in similarly treated wild-type mice
• following challenge with ovalbumin, anti-ovalbumin IgM antibodies are lower than in similarly treated wild-type mice
• following in vitro stimulation with ovalbumin or anti-CD3 epsilon antibodies, cells produce less interferon-gamma than wild-type mice
• following in vitro stimulation with ovalbumin or anti-CD3 epsilon antibodies, cells produce less IL-2
• following in vitro stimulation with ovalbumin or anti-CD3 epsilon antibodies, cells produce more IL-4 than wild-type mice

behavior/neurological
• during passive avoidance testing, mice display more frequent urination and defecation and decreased movement compared to wild-type mice
• however, passive avoidance behavior is normal
• despite normal motor coordination, mice exhibit decreased ambulation and time of rearing for the first 30 minutes when placed in a new environment
• mice exhibit increased locomotor activity during early portions of the light phase and decreased ambulation during the dark phase of a 12 hours light 12 hour dark cycle relative to similarly treated wild-type mice
• the ratio of ambulation during the light phase to total ambulation during 24 hours is increased compared to in wild-type mice
• however, total ambulation during a 24 hours period is normal
• mice rear less when placed in a new environment compared to wild-type mice

hematopoietic system
• B cell proliferation in response to anti-IgM is reduced 3- to 4-fold compared to in wild-type mice
• however, B cell proliferation in response to IL-4 alone or in combination with CD40LG or LPS is normal

cellular
