Lipopolysaccharides and glucagon-like peptide 1 : from molecular mechanisms to pathophysiology

2016

Obesity and type 2 diabetes are metabolic diseases which have reached epidemic proportions worldwide. These metabolic disorders are related to a low grade inflammation whose molecular origin is still unknown. Previous studies have highlighted the involvement of the gut microbiota and especially components of the cell wall of Gram(-) bacteria: lipopolysaccharides (LPS). We have recently shown that LPS enhance glucagon-like peptide 1 (GLP-1) plasma levels, a hormone which is known to stimulate insulin secretion. Moreover there would be a link between the nutritional qualities of food and LPS plasma levels. Thus diet, LPS and GLP-1 may be closely related. The present work focuses on i) the mol…
