Oxidative stress and post-stroke depression: possible therapeutic role of polyphenols?
Solo los usuarios registrados pueden traducir artículos

Post-stroke depression is a common neuropsychiatric affective disorder that may develop after a stroke event. In addition to abnormalities in the biogenic amine neurotransmitters and cytokine expression induced by stroke we will focus on the role of oxidative stress and hypothesize that polyphenols
A dietary polyphenol resveratrol acts to provide neuroprotection in recurrent stroke models by regulating AMPK and SIRT1 signaling, thereby reducing energy requirements during ischemia.

Increasing evidence has suggested that our view of stroke should be integrative, and thus a concept of dynamic interaction between cells belonging to the neurovascular unit, such as endothelial cells, astrocytes and neurons, is emerging. The functionality of this unit is altered by the complex

BACKGROUND
Polyphenols are probably the most known and investigated molecules of nutritional interest as micronutrients present in abundance in our diet. Some of the most important food sources of polyphenols in the Mediterranean diet are olives and olive oil. A growing body of evidence from animal
