Moderate wine consumption has been suggested to exert a positive
effect in prevention of neurodegenerative process and cognitive
impairment. With the ultimate aim of achieving a better understanding of
the molecular mechanisms behind this benefit, we have investigated the
role of certain wine- derived phenolic metabolites and aroma compounds
in the MAPK cascade (including ERK1/2, p38), one of the routes directly
related to inflammation in neuronal cells. Some of the tested phenolic
compounds, especially in the case of 3,4-dihydroxyphenylacetic acid,
showed a significant neuroprotective effect against SIN-1-induced
neuronal death. Regarding their effect over MAPK phosphorylation,
inmunoblotting technique revealed a beneficial and significant decrease
on the phosphorylation of p38 and ERK1/2 kinases after incubation with
wine constituents. In addition, activity of caspase3-like protease, an
executor of neuronal apoptosis and a downstream signal of MAPK, was
significantly diminished by 3-(3-hydroxyphenyl) propionic acid and
linalool, counterbalancing the increase produced by SIN-1. Altogether,
these results suggest that wine aroma, phenolic compounds and their gut
metabolites could exert neuroprotective actions by modulating MAPK
signalling and caspase-3 proteases activation, which are known to play a
key role in oxidative/ nitrosative stress-induced response.© The Authors, published by EDP Sciences 2016
