mortality/aging
neonatal lethality, incomplete penetrance ( J:280182 )

mortality/aging ( J:280182 )
N
• mice are born in Mendelian ratios and survive without any overt phenotype

immune system
abnormal NK cell differentiation ( J:280182 )
• mice show a defect in NK cell maturation with a 1.8-fold reduction of CD27+CD11b+ NK cells in the bone marrow and a 3-fold loss of CD27+CD11b+ NK cells in spleen
increased immature NK cell number ( J:280182 )
• mice show a 1.4-fold increase in the number of immature CD27+CD11b- NK cells in bone marrow but no significant change in spleen
decreased NK cell number ( J:280182 )
• mice exhibit reduced numbers of peripheral NK cells with a 2.9-fold reduction of NK cell number in spleen
• however, NK cell number is normal in the bone marrow
decreased mature NK cell number ( J:280182 )
• mice show a 6-fold reduction of mature CD27-CD11b+ NK cells in spleen, and 3-fold loss of CD27-CD11b+ NK cells in the bone marrow
