Modified versions of GLP-1 and GIP hormones that resist breakdown by DPP IV lower blood glucose more effectively in diabetic mice than the natural versions, and the location of a specific amino acid change (Abu8 in GLP-1) results in the strongest effect.

GLP-1 and GIP are hormones that increase insulin production and decrease glucagon production when nutrients are consumed, which helps control blood glucose levels.

A specific chemical change at position 8 in the GLP-1 hormone increases its ability to activate adenylate cyclase and trigger insulin release in laboratory cell systems more than a similar change at position 2 in the GIP hormone, suggesting that the location of modifications influences how these hormones interact with their receptors.

Losing weight by turning on a specific brain and gut signal (GLP-1) can help improve health problems linked to obesity, like high blood sugar or high blood pressure.

In obese individuals with type 2 diabetes and in obese mice, GLP-1 receptor agonists cause weight loss primarily from fat tissue, while muscle mass is largely preserved. This results in a higher proportion of muscle relative to total body weight and maintained muscle strength, even though the total amount of muscle decreases slightly.
