Abstract
Purpose of review: Glucagon increases hepatic glucose production and in patients with metabolic diseases, glucagon secretion is increased contributing to diabetic hyperglycemia. This review explores the role of amino acids and lipids in the regulation of glucagon secretion and how it may be disturbed in metabolic diseases such as obesity and metabolic associated fatty liver disease (MAFLD).
Recent findings: Human and animal studies have shown that MAFLD is associated with glucagon resistance towards amino acid catabolism, resulting in elevated plasma levels of amino acids. A recent clinical study showed that MAFLD is also associated with glucagon resistance towards lipid metabolism. In contrast, MAFLD may not decrease hepatic sensitivity to the stimulatory effects of glucagon on glucose production.
Summary: Elevated plasma levels of amino acids and lipids associated with MAFLD may cause diabetogenic hyperglucagonemia. MAFLD and glucagon resistance may therefore be causally linked to hyperglycemia and the development of type 2 diabetes.
期刊介绍：
With its easy-to-digest reviews on important advances in world literature, Current Opinion in Lipidology offers expert evaluation on a wide range of topics from six key disciplines including nutrition and metabolism, genetics and molecular biology, and hyperlipidaemia and cardiovascular disease. Published bimonthly, each issue covers in detail the most pertinent advances in these fields from the previous year. This is supplemented by a section of Bimonthly Updates, which deliver an insight into new developments at the cutting edge of the disciplines covered in the journal.
