Brain-derived neurotrophic factor: A new adipokine

Since leptin discovery in 1994, an extensive body of work has been demonstrating that adipose tissue (mainly its white phenotype) expresses not only metabolic, but also endocrine and paracrine phenotypes, particularly in adipobiology of disease. This new biology is achieved predominantly through secretion of adipokines, which include more than hundred highly active signaling proteins. However, studies on adipobiology of neurotrophins have recently emerged, nerve growth factor being one example of adipose-derived neurotrophins. Here we present data showing that brain-derived neurotrophic factor is also expressed in both white and brown adipose tissue. © Bulgar ian Society for Cell Biology.
