Neither markers for activated microglia (IBA, top row) nor for Aβ-load (W02, lower row) were significantly different after long-term ghrelin agonist treatment in the dentate gyrus
(a) and stratum oriens (b). Only the level of activated microglia in the olfactory bulb of ghrelin-agonist-treated animals showed a tendency to be lower than in animals fed the high-GI diet alone ((c), Kruskal-Wallis test, followed by post-hoc Dunn’s multiple comparisons test, p = 0.057). Bars indicate SEM.
