The two tocopherols can act anti-inflammatory either by affecting transcription of inflammatory genes by modulating the signaling pathways involved in upregulation of these genes, or by inhibiting the activity of enzymes involved in eicosanoid biosynthesis. αT acts primarily through inhibition of cell signaling, while γT (and its water-soluble metabolite γ-CEHC) potently inhibits COX-2-mediated biosynthesis of PGE2. Akt, protein kinase B; p38MAPK, p38 mitogen-activated protein kinase; PDK, phosphoinositide-dependent kinase; PI3K, phosphatidylinositol 3-kinase; PKC, protein kinase C; PLC, phospholipase C; PP2A, protein phosphatase 2A;
