Ester-linked fatty acid profile in the cortex of mice inoculated with different age-related microbiota. Lipids were extracted from the cortex of mice inoculated with fecal microbiota of young mice (+ Microb YM) or old mice (+ Microb OM). The results correspond to quantification of fatty acid methyl esters (FAME) derivatives by GC-FID. The percentage of each fatty acid relative to that of total fatty acids (100%) was determined. (A) Heat map showing the abundance of each fatty acid relative to total fatty acids, defined as 100% (B) Relative abundance of the eight most abundant fatty acids quantified in the brain. All data are presented as mean ± SEM. n = 7 for the group of mice inoculated with the microbiota of young mice and n = 8 for the group of mice inoculated with the microbiota of old mice. Comparisons were done between the two groups of mice (+ Microb YM and + Microb OM). *p < 0.05 and **p < 0.01.
