Figure 4From: Transcriptional regulation by Poly(ADP-ribose) polymerase-1 during T cell activationIL-4 production in both Parp-1+/+ and Parp-1-/- T cells. T cells were stimulated for 24 h with anti-CD3 or anti-CD3 + anti-CD28 mAbs. The level of IL-4 was measured by ELISA. An experiment representative of three experiments is shown. Results represent the mean value ± SD. * P < 0.05 in t-test.Back to article page
