immune system

immune system phenotype ( J:168475 )

N • mice show normal T cell development in the thymus and periphery

increased T cell number ( J:168475 )

• engrafted mice show a nearly 2-fold increase in absolute number of T cells, while the B cell compartment is not different from wild-type

increased single-positive T cell number ( J:168475 )

• in draining lymph nodes, a significant increase in CD4+ and CD8+ T cells is detected

increased macrophage cell number ( J:168475 )

• animals exhibit a significant increase in macrophage antigen-1-positive cells in spleens

abnormal CD4-positive helper T cell morphology ( J:168475 )

increased splenocyte number ( J:168475 )

• mice show 1.5-fold increase splenocyte number in engrafted mice

abnormal immune system physiology ( J:168475 )

• skin and cardiac allografts from BALB/c mice to Rbpj-deficient mice show decreased survival time

• grafts of both tissue type show increased leukocyte infiltration

increased T cell proliferation ( J:168475 )

• percentage of proliferating CD4+ cells is significantly increased in lymph nodes and spleen; a similar increase in CD8+ T cells in spleen and lymph nodes is observed in engrafted animals

abnormal regulatory T cell physiology ( J:168475 )

• suppression activity of CD4+CD25+ regulatory T cells is significantly attenuated in vitro; generation of Treg cells in vivo in graft recipients is not altered
