Stimulation of CD25(+)CD4(+) regulatory T cells through GITR breaks immunological self-tolerance.

abstract：:During the productive interaction of T cells with antigen-presenting cells (APCs), engaged receptors, including the T cell antigen receptors and their associated tyrosine kinases, assemble into spatially segregated supramolecular activation clusters (SMACs) at the area of cell contact. Here, we studied intracellular s...
