abstract：:Naturally occurring CD4(+)CD25(+) regulatory T cells (nT(R)) comprise a separate lineage of T cells that are essential for maintaining immunological tolerance to self. Here we demonstrate that the level of phosphorylation of the TCR zeta-chain is approximately 1.5- to 4-fold higher in nT(R) as compared with CD4(+)CD25...
