From: Neuron-derived extracellular vesicles in blood reveal effects of exercise in Alzheimer’s disease
NDEV exercise effects stratified by APOE ε4 genotype. Bar graphs show the concentrations of proBDNF (A), BDNF (B), and humanin (C) in NDEVs from ε4 carriers and non-carriers from the exercise group at baseline (light blue) and 16 weeks (dark blue). Graphs show the estimated marginal mean ± standard error of the mean from repeated measures mixed-effects models. * indicates p < 0.05; ns: not significant
