Normally, GLP-1 is released from the gut after eating and signals the brains appetite-control centers while also slowing stomach emptying

The drug companies believe that hitting more receptors induces better weight-loss effects, which does appear to be true, but when it comes to what this is doing across different immune populations, downstream signaling can be completely changed by adding on these extra agonists, she says

These compounds help support gut barrier function and metabolic signaling pathways involved in glucose balance

Intriguingly, however, peripheral application of the GLP1 receptor agonist, exendin4 (Ex4), which should reach all GLP1 receptors accessible for endogenous gutderived GLP1, failed to induce cFos immunoreactivity in PPG neurons (Holt et al., 2020)
