title: [Effect of resveratrol alone and its combination with cyclosporin A on the immune function of human peripheral blood T lymphocytes].
abstract: OBJECTIVE
  To investigate the effect of resveratrol (Res) alone and its combination with cyclosporin A (CsA) on the proliferation of human peripheral blood T lymphocytes (hPBTCs), transformation into lymphoblasts, as well as IL-2 and INF-gamma production.
  
  
  METHODS
  The proliferation of hPBTCs was detected by MTT colorimetry. The lymphocyte transformation rate was examined by morphologic method. The levels of IL-2 and INF-gamma in lymphocyte culture supernatant were detected by ELISA.
  
  
  RESULTS
  When the concentration of resveratrol was over 2.5 mg/L, especially 10 mg/L, the proliferation and transformation rate of hPBTCs decreased significantly (P<0.05). The levels of IL-2 and INF-gamma in lymphocyte culture supernatant reduced markedly (P<0.05), on condition that the concentration of resveratrol was over 5 mg/L. The combination of more than 2.5 mg/L of resveratrol with cyclosporine A had synergism.
  
  
  CONCLUSIONS
  Resveratrol can suppress notably the proliferation and transformation of human lymphocytes and the combination of resveratrol at a given concentration with cyclosporine A can enhance immune suppression.
