Identification of dietary modulators of cognitive ageing and brain plasticity and proof of concept of efficacy for preventing/reversing cognitive decline.

Projectomschrijving

Understanding how diet modifies cognitive ageing represents the next frontiers for developing prevention strategies. A key may rely on elucidating the exact combination of dietary bioactives capable of modulating cognitive decline via brain plasticity, a major compensatory mechanism to maintain cognitive function. Another important question is the sensitive population in which such nutritional intervention should be undertaken. We hypothesized that (i) there exists a combination of dietary bioactives capable of modulating cognition and brain plasticity, (ii) dietary modulation of brain plasticity and cognition start in early-life and occurs throughout life and (iii) exposure to stress/genetic predisposition are vulnerability factors to consider.

We carried out a translational project across nutrition, epidemiology, and neurosciences leveraging human data/serum samples and mouse models and using innovative approaches of: (i) dietary exposure assessment (the food metabolome), (ii) human brain plasticity (in vitro parabiosis to assess neurogenesis and microglial function, lipidomics to assess neuronal integrity), and (iii) cognitive ageing modeling (early-life stress mouse model).

D-CogPlast started with a discovery stage in humans, identifying a set of dietary bioactives from the food metabolome associated with cognitive decline, along with vulnerable populations, in 200 individuals with accelerated cognitive decline over 13+ years against 200 individuals with preserved cognition. This was validated in 400 participants from a separate cohort. The second investigated the ability of the identified set of bioactives predictive of cognitive decline to modulate brain plasticity and neuronal integrity. The third stage consisted in a proof-of-principle dietary intervention with identified bioactives in a mouse model of cognitive decline.

On completion of this project we have (i) identified dietary compounds providing protective effect against cognitive ageing and brain plasticity alteration, (ii) identified vulnerable populations responding to the impact of diet on cognitive decline, (iii) provided evidence of brain plasticity as targets of choice for bioactives intervention to prevent/slowdown cognitive decline and (iv) provided a proof-of-principle life-long dietary intervention for preventing/rescuing cognitive decline. It is expected that the bioactives identified and validated could lead to dietary interventions and recommendations for cognitive decline prevention.

Eindverslag

Doel is te bepalen welke voedingsstoffen gunstig zijn voor ons brein. Cognitieve achteruitgang, zoals vergeetachtigheid, komt vaak voor bij ouderen. Naar nu blijkt wordt het begin en de mate van deze achteruitgang al mede bepaald door factoren in ons vroege leven zoals stress, maar ook voeding speelt hier een belangrijke rol. Bekend is bv dat een Mediterraan dieet de kans op cognitieve achteruitgang verkleind. In dit onderzoek proberen we te bepalen welke voedingsstoffen van belang zijn bij het tegengaan van cognitieve achteruitgang.
Dit doen we allereerst door voedingsstoffen in het bloed van mensen die gezond oud worden, te vergelijken met mensen die cognitief achtergaan. Daarnaast willen we begrijpen hoe het precies werkt en onderzoeken we ook muizen die blootgesteld zijn aan stress in hun vroege leven. Dit leidt tot cognitieve achteruitgang in volwassenheid. Hier willen we onderzoeken of een voedingsinterventie die achteruitgang kan herstellen door ze een dieet te geven gebaseerd of voedingsstoffen die we geïdentificeerd hebben in de cognitief gezonde mensen. Daarna willen we nader begrijpen hoe dit werkt door het metabolisme, de aanmaak van nieuwe hersencellen en het immuunsysteem te bestuderen.
