Vitamin C and E Suppress Mitogen-Stimulated Peripheral Blood Mononuclear Cells in vitro

Abstract

Neopterin production and tryptophan degradation in monocyte-derived macrophages are both triggered by the pro-inflammatory cytokine interferon-gamma. Thus, their concurrent suppression by vitamin C and E suggests an effect on the formation and release of this cytokine by stimulated T cells. These findings may be related to the general health benefits which are associated with the antioxidant nature of these vitamins.
