Because the majority of the -cells do not express GLP-1R, and also because GLP-1 inhibits glucagon secretion even in T1D patients with low insulin pancreatic reserve, the mechanism by which GLP-1 decreases glucagon secretion is still a matter of debate [15]
This higher concentration means a smaller injection volume for the same dose, and it also changes how the insulin absorbs into the body, creating a flatter, more prolonged activity profile that can last up to 36 hours
However, the relevance of GLP-1 signaling in genetic obesity may extend beyond this bypass mechanism
For researchers evaluating peptide options for weight loss , the speed factor may be as important as the total magnitude of effect
