Amino acid(AA) concentrations are decreased in the cerebrospinal fluid (CSF) but not plasma of type 2 diabetes (T2D) monkeys. (A) T2D monkeys had significantly decreased branch chain amino acids (BCAA), (B) total amino acid concentrations, (C) essential AAs, (D) aromatic AAs, and (E) basic AAs, but not (F) acidic AAs. (G–L) Conversely, plasma amino acid concentrations were not different between groups. p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; and ∗∗∗∗p < 0.0001; one-way ANOVA with Tukey’s post hoc test. Values represent mean ± SEM.
