This PDF file includes:

  • Methods
  • Fig. S1. Suppression of cytokine secretion is retained after removal of Tregs.
  • Fig. S2. Treg-mediated rapid suppression of IL2 expression in Tcons also occurs in the presence of APCs.
  • Fig. S3. CTLA-4 is not involved in the suppression of cytokine gene expression.
  • Fig. S4. Proximal TCR signaling is not altered in suppressed Tcons.
  • Fig. S5. Suppression of NFAT and NF-κB activation is independent of the antibody used to activate Tregs.
  • Fig. S6. Phosphorylation of ERK and p38 is not affected in suppressed Tcons.
  • Fig. S7. The block in Ca2+ influx in Tcons is not caused by allogeneic responses and requires 30 min of previous coculture with Tregs.
  • Fig. S8. Suppression of Ca2+ signaling is independent of cAMP.
  • Fig. S9. Tregs, but not Tcons, pre-activated with covalently plate-bound antibody against CD3 suppress Ca2+ signaling in responder Tcons.
  • Fig. S10. NFAT and NF-κB activation in Tcons is Ca2+-dependent.
