A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a Swansea-led research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson’s Disease.
Blood-borne factors such as hormones regulate the process of brain cell formation – known as neurogenesis – and cognition in adult mammals.
The research team focused on the gut hormone acyl-ghrelin (AG), which is known to promote brain cell formation. A structure change to the hormone results in two distinct forms: AG and unacylated-ghrelin (UAG).
