Reduced secretion of neuronal growth regulator 1 contributes to impaired adipose-neuronal crosstalk in obesity

Abstract

Adipose tissue is an important secretory organ, but less is known about the secretory activity of perivascular fat. Here the authors use proteomics analysis on secretomes from perivascular fat to identify neuronal growth regulator 1 as an adipocyte-derived neurotrophic factor, whose decreased secretion in obesity results in a loss of sympathetic innervation of adipose depots in mice.
