Regulation of natriuretic peptides postprandially in vivo and of their receptors in adipocytes by fatty acids in vitro

Adipocytes and AT show a characteristic expression of NPRs. FA are able to regulate NPR expression differentially. There is a postprandial and negative regulation of serum NT-proANP concentrations after OLTT and of NPR-A after FA stimulation. Both effects could represent a novel hypothetical negative feedback mechanism on adipocyte lipolysis.
