Age-Related Changes in the Gut Microbiota Modify Brain Lipid Composition
2020
PMCID: PMC6970973; International audience; Understanding the molecular mechanisms underlying the changes observed during aging is a prerequisite to design strategies to prevent age-related diseases. Aging is associated with metabolic changes, including alteration in the brain lipid metabolism. These alterations may contribute to the development of pathophysiological conditions. Modifications in the gut microbiota composition are also observed during aging. As communication axes exist between the gut microbiota and the brain and knowing that microbiota influences the host metabolism, we speculated on whether age-associated modifications in the gut microbiota could be involved in the lipid ch…

Lipid and homeostatic alterations in nervous tissues associated with aging and metabolic dysregulations: implication of gut microbiota and autophagy
2020
The retina and the brain are two nervous tissues rich in lipids. Aging and metabolic syndrome (MetS) are associated with functional and physiological alterations of these tissues as well as modifications in the composition of the gut microbiota. The global objective of this thesis work is to understand the lipid and homeostatic alterations in aging and MetS contexts in the retina and the brain. In a first study, we evaluated the impact of the modifications in the composition of the gut microbiota associated with aging on the lipid/fatty acid contents of the liver and the brain (cortex). We showed that colonization of germ-free mice with the gut microbiota of old mice modulated the hepatic e…
