Neuro-Adipose interactions (biactome). Implication in cardiometabolic disease.

Cardiometabolic diseases (CMD) are the number one cause of death globally, and the major CMD's phenotypes are atherosclerosis, hypertension, obesity, type 2 diabetes and metabolic syndrome. Arguably, since the leptin discovery in 1994 the field of study on adipose tissue, adipobiology, has been witnessing a number of paradigm shifts. One of them introduced the adipose tissue in the list of endocrine and paracrine organs of the human body. It was discovered a dazzling number of adipose- delivered secretory proteins, collectively termed adipokines. Among them are proteins improving glucose, lipid and energy metabolism, that is, metabotrophic factors (metabotrophins) (from Greek metabole, and trophe, nutrition, means "nutritious for metabolism"). Examples include adiponectin, apelin, visfatin, nerve growth factor, brain-derived neurotrophic factor and insulin-like growth factor- 1, each of them mediating both metabotrophic and neurotrophic effects. Hence a novel field of research, neuroadipocrinology - a relative of neuroendocrinology, was launched. A piece of it designated biactome (neuro-adipose interactions) is herein highlighted. Its implications in the pathogenesis and therapy of major CMD (atherosclerosis, hypertension, obesity, type 2 diabetes, metabolic syndrome) are discussed.
