immune system
• in mice by 26 days of age
• can be prevented with adoptive transfer at birth of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• by 26 days of age
• can be prevented with adoptive transfer at birth of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• there is a 2 to 5 fold reduction in the percentage of CD25-postive CD4 T cells in both the thymus and lymph nodes
• transgeneic expression of Il2rb in the thymus rescues number of regulatory T cells
• increased in size at 26 days of age
• can be prevented with adoptive transfer at birth of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• percentage of CD4 and CD8 T cells that express high levels of activation markers is increased
• T cells are hyporesponsive to inflammatory cytokines as measured by in vitro proliferation assays
• expression of activation markers is normalized upon transfer of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• in mice by 26 days of age
• can be prevented with adoptive transfer at birth of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• in mice by 26 days of age
• can be prevented with adoptive transfer at birth of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• in mice by 26 days of age
• can be prevented with adoptive transfer at birth of 1 x 105 CD25-positive CD4 T cells from wild-type mice
• adoptively transfered regulatory T cell expand at least 15 to 20 times until they make up 3-5% of the total cells in the lymph nodes and spleen
• regulatory T cells were unable to engraft in wild-type mice
