mortality/aging
• Background Sensitivity: 70% of mice die in utero, which is more than on a mixed 129P2/OlaHsd C57BL/6 mixed background

vision/eye
• inflammation of the ocular surfaces is accompanied by eye lid swelling, alopecia and abnormal hair growth around the eye
• at 4 to 6 weeks of age, mice develop inflammation of the eye lids
• many CD4+ cells, some CD8+ cells and few CD45R/B220+ cells infiltrate the skin of the eyelids
• 2 weeks after the onset of symptoms, mice exhibit infiltration of the submucosal area of the conjunctiva with inflammatory cells
• inflammatory cells in the conjunctival tissue are CD4+ and CD45%/B220+ while CD8+ cells are only detected in the conjunctival epithelium
• 2 weeks after the onset of symptoms, mice exhibit severe decrease in the number of goblet cells in the conjunctival epithelia

immune system
• 10 weeks after the onset of symptoms, IgE levels are higher than in wild-type mice

homeostasis/metabolism
• at 6 weeks of age, mice exhibit inter- and intracellular edema of the epidermis around the mouth and eyes
