| Summary |
5 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
| N |
• dendritic cells in mutants show relatively normal induction of T cell stimulatory molecules and cytokine mRNAs when stimulated with poly(I:C) or LPS
• dendritic cells show essentially normal responses and maturation upon infection with NDV
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• proliferative responses of both CD4+ and CD8+ T-cells from sensitized mice is somewhat increased
|
|
• proliferative responses of both CD4+ and CD8+ T-cells from sensitized mice is somewhat increased
|
|
• exaggerated response to challenge after presensitization in contact hypersensitivity test
• effect can be transferred to naive mice using CD8+ cells from sensitized mice
|
|
• a 2 fold increase in Il4 production by CD44+ cells
|
|
• susceptibility to encephalomyocarditis virus tested
• response to infection and survival were similar to control mice; however, pretreatment of mice with IFNgamma failed to improve survival as it did in controls
|
|
• proliferative responses of both CD4+ and CD8+ T-cells from sensitized mice is somewhat increased
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• susceptibility to encephalomyocarditis virus tested
• antiviral effect of interferon was suppressed even more than in the case of either single homozygote
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• viability is increased up to 63% for mutant mice homozygous for the mutation in Eif2ak2 compared to mutant mice wild-type for Eif2ak2 (~32% viability)
|

|
|
• spongiotrophoblasts and glycogen cells have more diploid DNA content at E14.5
|
|
• elevated gammaH2A.X signalling indicating decreased DNA repair and persistence of DNA damage in spongiotrophoblasts
|
|
• elevated gammaH2A.X signalling indicating decreased DNA repair and persistence of DNA damage in spongiotrophoblasts
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
 |
