immune system
• mice produce more IgE+ B cells than wild-type mice
• mice produce more memory or effector T cells than wild-type mice
• as determined by bone marrow transplant assays, mice exhibit a cell-intrinsic defect in regulatory T cell development
• mice produce more CD11b+ IL-5R+ eosinophils or basophils than wild-type mice
• at 5 to 6 weeks of age, mice exhibit fewer regulatory T cells in the thymus, spleen and lymph nodes compared to wild-type mice due to a cell-intrinsic defect in regulatory T cell development
• while the proportion of regulatory T cells increases with age it remains 10% to 20% of wild-type
• in mice older than 8 weeks
• in mice older than 8 weeks
• T cells undergo reduced proliferation compared to wild-type cells after TCR stimulation
• CD4+ T cells exhibit no calcium influx after depletion with thapsigargin or stimulation with anti-CD3 antibodies and ionomycin unlike wild-type cells
• CD4+ T cells produce almost no IL-2 and very little interferon-gamma after stimulation with phorbol ester PMA and ionomycin or with anti-CD3 and anti-CD28 antibodies compared to wild-type cells
• CD4+ T cells produce very little interferon-gamma after stimulation with phorbol ester PMA and ionomycin or with anti-CD3 and anti-CD28 antibodies compared to wild-type cells
