The Claim

Neuronal GLP1 receptors in mice are necessary for the appetite-suppressing and weight-reducing effects of liraglutide, as genetic deletion of these receptors abolishes reductions in food intake and body weight following treatment, while glucose tolerance remains unaffected.

Source: Neuronal GLP1R mediates liraglutide's anorectic but not glucose-lowering effect.

How it works
1 study reviewed
In plain English

In mice, liraglutide reduces appetite and body weight only if neuronal GLP1 receptors are present; when these receptors are absent, the drug has no effect on food intake or weight, but still improves glucose tolerance.

See the scientific wording

In mice, neuronal GLP1 receptors are necessary for the appetite-suppressing and weight-reducing effects of liraglutide, as mice lacking these receptors showed no reduction in food intake or body weight despite treatment, while glucose tolerance improved normally, indicating a dissociation between the drug's metabolic and anorectic actions.

Why this might work

Liraglutide enters the brain and binds to receptors on specific nerve cells in a region that controls hunger. This binding turns on those nerve cells and turns off other nerve cells that drive eating, causing the animal to eat less and lose weight. If those receptors are missing, liraglutide cannot trigger this change, so eating and weight stay the same, even though blood sugar still improves.

  1. Study: Neuronal GLP1R mediates liraglutide's anorectic but not glucose-lowering effect.

    In mice, liraglutide can only make them eat less and lose weight if brain neurons have GLP1 receptors; if those receptors are removed, the drug stops working for weight loss but still helps lower blood sugar.
