The transcriptional events that control T cell tolerance are still poorly understood. To investigate why tolerant T cells fail to produce interleukin (IL)-2, we analyzed the regulation of NFκB-mediated transcription in CD4+ T cells after tolerance induction in vivo. We demonstrate that a predominance of p50-p50 homodimers binding to the IL-2 promoter κB site in tolerant T cells correlated with repression of NFκB-driven transcription. Impaired translocation of the in tolerant T cells a of of tolerant T cells of the the of of the in tolerant T We demonstrate the induction of the cell in tolerant T cells binding to the that the of the repression of IL-2 are in tolerant CD4+ T cells in vivo.
