Project: Ghrelin – a unique biomarker for nutritional state and inflamm-aging.

This project aims to determine whether current knowledge of ghrelin in animal models is applicable to humans, and to determine whether ghrelin is a good biomarker of aging. Ghrelin is a hormone correlated with increasing food intake and promoting obesity, inflammation and metabolic dysfunctions in humans, however, application of knowledge gained over the past few decades is limited. Currently the regulation of aging immunity – or “inflamm-aging” – is not well understood, however, researchers propose that ghrelin could be a reliable biomarker for the prediction of metabolic and inflammation states in aging and inform healthy aging interventions.
