| Summary |
3 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• all pups die between 0.5 and 1.5 days after birth
|
|
• null mice are born at lower than the expected Mendelian frequency
|
|
• MEFs derived from these mice have defects in store-operated Ca2+ influx
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• only a third of the mice live past 90 days of age
|
|
• half the mice die within one day of birth
|
|
• mice are consistently 25-30% smaller by bodyweight compared to controls regardless of age
|
|
• mast cells show defects in store-operated Ca2+ influx when activated by thapsigargin treatment
|
|
• B cells show defects in store-operated Ca2+ influx when activated through their BCR, by thapsigargin treatment, or my maximally stimulating them with ionomycin
|
|
• nave T cells show defects in store-operated Ca2+ influx only when activated in the presence of low (0.5mM) extra-cellular Ca2+
• antigen experienced T cells show defects in store-operated Ca2+ influx at physiological extra-cellular calcium concentrations
|
|
• double-positive thymocytes show a substantial decrease in Ca2+ flux when activated
|
|
• there is a substantial decrease in the number of IFN-gamma producing CD4+ T cells, as well as a reduction in mean cytokine production per cell, when cultured in vitro under nave and Th1-differentiating conditions
• cytolytic CD8+ T cells also have decreased IFN-gamma production
|
|
• there is a substantial decrease in the number of IL10-producing CD4+ T cells, as well as a reduction in mean cytokine production per cell, when cultured in vitro under Th2-differentiating conditions
|
|
• there is a substantial decrease in the number of IL2-producing CD4+ T cells, as well as a reduction in mean cytokine production per cell, when cultured in vitro under nave and Th1-differentiating conditions
|
|
• there is a substantial decrease in the number of IL4-producing CD4+ T cells, as well as a reduction in mean cytokine production per cell, when cultured in vitro under Th2-differentiating conditions
|
|
• eyelid irritation is observed in all mice with variable severity
• irritation is independent of cage bedding (i.e. not related to allergies)

|
|
• double-positive thymocytes show a substantial decrease in Ca2+ flux when activated
|
|
• sporadic hair loss occurs in these mice
• mice showed a patchy pattern of hair loss, concentrated on the occipital region of the skin of the skull
• affected mouse in initially show a progressive spread of the hair-less region toward the tail, and then a partial regrowth of hair in the affected region
• with increasing age, hairless patches are replaced with sparse hair growth
|
|
• vibrissae are shorter and thinner than controls
• vibrissae follicles are smaller and less developed
|
|
• double-positive thymocytes show a substantial decrease in Ca2+ flux when activated
