To read the full abstract: J Clin Endocrinol Metab. 2020; 105(5): 1427–1434. PMID: 31853550.GDF15 is a stress-induced hormone that acts in the hindbrain to activate neural circuits involved in aversive responses and reducing food intake and body weight in animal models (1). In humans, GDF15 is widely expressed, with highest concentrations seen in placental trophoblasts, followed by kid...

To read the full abstract: Neuroimage. 2019; 197:493–501. PMID: 31077842.A large body of evidence suggests that the early environment can influence the health and wellbeing in children later in life. Variability in susceptibility to environmental stimuli might be mediated by interactions between genetic variations and the environment. The hypothalamic-pituitary adrenal (HPA) axis is th...
