Lei Zhang

Senior Research Officer at Garvan Institute of Medical Research

Lei Zhang is a Senior Research Officer at the Garvan Institute of Medical Research, located in the Greater Sydney Area.2 Their research focuses on neuropeptide Y (NPY) in the arcuate nucleus (ARC) and its role in regulating feeding behavior, particularly under obese conditions.1

Zhang's work has contributed to understanding how NPY promotes feeding in obesity. Their research has identified a subset of ARC agouti-related peptide (Agrp)-negative NPY neurons that control proopiomelanocortin (POMC) neurons expressing Npy2r. This newly discovered circuitry strongly drives feeding when activated and reduces feeding when inhibited.1

Zhang's findings suggest that under energy surplus conditions, such as those induced by a high-fat diet or in genetically obese mice, high-affinity NPY2R on POMC neurons can still drive food intake and enhance obesity development. This occurs via NPY released predominantly from Agrp-negative NPY neurons, even when ARC NPY levels generally drop.1

Zhang's educational background includes studies at the University of Tasmania, although specific degree details are not provided in the available information.2
