Abstract

The gut-hormone acyl-ghrelin (AG) is known to promote adult hippocampal neurogenesis. Hornsby et al. combine in vitro and in vivo rodent models, alongside analysis of human plasma, to show that unacylated-ghrelin (UAG) impairs neurogenesis and that the circulating AG:UAG ratio is reduced in Parkinson's dementia.
