After systemic administration, they engage both GLP1R and GIPR simultaneously in native tissue, enabling the study of receptor engagement, metabolic responses, and therapeutic effects at the cellular and organ level, going beyond localization to provide functional readouts directly in living models

As a result, GLP-1 receptor agonists (GLP-1RAs) have been developed

Researchers have been particularly interested in its action on: GLP-1 receptors GIP receptors Glucagon receptors While these scientific terms may sound technical, the practical implication is easier to understand
