    The role of Toll-like receptor 4 (TLR-4) in wine-induced cardioprotection
    (2012) Albertyn, Zulfah; Lecour, Sandrine; Opie, Lionel H
    Moderate and chronic consumption of red wine confers cardioprotection. Melatonin, present in wine, may contribute to this cardioprotective effect. Melatonin confers cardioprotection via the activation of tumor necrosis factoralpha (TNF-α) and the signal transducer and activator of transcription-3(STAT-3), via mechanisms that still remain to be delineated. We therefore hypothesise that South African red and white wines confer a cardioprotective effect in relation to their melatonin content. Furthermore, we propose that the cardioprotective effect of melatonin (at a concentration found in red wine) is dependent on the activation of Toll-like receptor 4 (TLR-4) to activate TNF-α/STAT-3.
