immune system
abnormal NK cell differentiation ( J:280182 )
• mice show subtle changes in the expression of NK cell surface receptors and a defect in NK cell maturation with a 5-fold reduction of CD27+CD11b+ NK cells in spleen and a 2.7-fold loss of CD27+CD11b+ NK cells in the bone marrow
increased immature NK cell number ( J:280182 )
• mice show a 1.3-fold increase in the number of immature CD27+CD11b- NK cells in bone marrow but no significant change in spleen

• mice show a 2-fold reduction in the % of proliferating Ki67+CD11b- NK cells in the bone marrow, with no change in the % of Ki67+CD11b+ cells
• splenic CD11b- NK cells show no change in Ki67 staining, and even a small increase in the CD11b+ fraction relative to controls (10.8% vs 6.8%)
