Based on the OGTT, rats with similar glucose tolerance profile were paired, then these rats were randomized into treatment groups ( Figure S2 )
Adipose tissue inflammation and metabolic dysfunction in obesity
While B vitamins are water-soluble and are generally excreted in the urine when in excess, extremely large and repeated doses can overwhelm the body's ability to eliminate them efficiently
Recent studies provide new evidence supporting the paracrine nature of intestinal GLP-1, whereby Serotonin-(5-HT)-secreting enterochromaffin (EC) cells are directly stimulated by locally produced GLP-1, which in turn stimulate afferent Vagal nerves (Figure 2) bridging the gut to brain axis
In isolated human islets, we confirmed that hGIP stimulated glucagon secretion, GLP-1 decreased glucagon secretion and the combination of the two peptides offset each other to produce a rate of glucagon secretion that matched unstimulated levels (Fig
