Tissue inflammation of ears of tagged Trim21tm1MwahTrim21tm1Mwah mice

mortality/aging
• a slightly reduced (22% vs. 27%) Mendelian ratio homozygous mice were born
• time of death was not reported

hematopoietic system
• in mice with dermatitis
• splenic CD3+ T cells of homozygous mice had an increased frequency of T cells with an activated phenotype splenic CD3+ T cells of homozygous mice had an increased frequency of T cells with an activated phenotype splenic CD3+ T cells of homozygous mice had an increased frequency of T cells with an activated phenotype
• mice treated with Oxazolone showed accumulation of T cells with an activated phenotype
• there is no apparent immune phenotype or other physical abnormalities present in naive unmanipulated homozygous mice

immune system

• mice treated with Oxazolone showed accumulation of T cells with an activated phenotype
• there is no apparent immune phenotype or other physical abnormalities present in naive unmanipulated homozygous mice
• production of high amounts of the proinflammatory cytokines IL-6, IL-12/IL-23p40, TNF-alpha, and IL-17 and IL-23R expression after application of Oxazolone
• production of high amounts of the proinflammatory cytokines IL-6, IL-12/IL-23p40, TNF-alpha, and IL-17 and IL-23R expression after application of Oxazolone
• in mice with dermatitis
• development of systemic autoimmunity
• mice with dermatitis developed antinuclear antibodies (ANAs), with specificity for DNA, and autoantibodies to several lupus- associated autoantigens and other autoantigens
• significantly higher contact hypersensitivity to low doses of the contact-sensitizing agent Oxazolone significantly higher contact hypersensitivity to low doses of the contact-sensitizing agent Oxazolone significantly higher contact hypersensitivity to low doses of the contact-sensitizing agent Oxazolone
• 25 wk after application of metal ear tags, >90% of homozygous mice had developed a very severe and progressive dermatitis emanating from the tagged ear, which did not occur in WT littermates

homeostasis/metabolism
• production of high amounts of the proinflammatory cytokines IL-6, IL-12/IL-23p40, TNF-alpha, and IL-17 and IL-23R expression after application of Oxazolone
• production of high amounts of the proinflammatory cytokines IL-6, IL-12/IL-23p40, TNF-alpha, and IL-17 and IL-23R expression after application of Oxazolone
• kidney pathology with substantiated mesangium and intraglomerular immunoglobulin depositions, as well as proteinuria

renal/urinary system
• kidney pathology with substantiated mesangium and intraglomerular immunoglobulin depositions, as well as proteinuria

integument
• 25 wk after application of metal ear tags, >90% of homozygous mice had developed a very severe and progressive dermatitis emanating from the tagged ear, which did not occur in WT littermates
