Course delivery
The activity will be structured in 3 lectures:
1) Controversial role of oxysterols in Alzheimer’s disease pathogenesis (Dr Paola Gamba/Dr Gabriella Testa, University of Turin) – 2 hours
2) Role of astrocyte reactivity in Alzheimer’s disease progression (Dr Gabriella Leonarduzzi/Dr Erica Staurenghi) – 2 hours
3) Use of antioxidants or other strategies to counteract the pathological effects of oxysterols (Dr Gabriella Testa, University of Turin) – 1 hours

Program
Cholesterol oxidation products, known as oxysterols, are potentially involved in the pathogenesis of major chronic human diseases, including Alzheimer's disease (AD).
It is well documented that altered cholesterol metabolism in the brain and hypercholesterolemia, together with oxidative stress and neuroinflammation, significantly contribute to AD pathogenesis.
The analysis of oxysterols in plasma and brain may contribute to clarifying the role of cholesterol metabolism in AD pathogenesis; in particular, it is important to highlight their effects on brain cells (neurons, astrocytes,…) and on the modulation of certain signaling pathways that can act on cell-death or cell survival. Deepening these aspects could be useful for developing new therapeutic strategies to prevent or slow AD progression.
