In this review, we present the individual signaling pathways for GLP-1R and GIPR in the pancreatic beta cell with a focus on the shared signaling pathways of the two receptors and interpret the implications of GLP-1R-GIPR co-activation in the light of recent co-activating therapeutic compounds...
We have shown that GLP-1 and also GIP analogues are neuroprotective in the 1-methyl-4-phenyl 1,2,3,6-tetrahydropypridine (MPTP) mouse model of PD, demonstrating that both incretin signalling pathways protect the brain from the MPTP induced pathology such as motor impairment, an increase of...

Circulating GIP and IL-1RA levels were associated with T2D. Nine of the 11 cytokines and hormones (exceptions GLP-1 and IL-6) were associated with HOMA-S, HOMA-B, or both among non-T2D individuals. Two-stage least squares MR analysis provided evidence for a causal effect of GIP and IL...
The present invention relates to compounds which have agonist activity at the glucagon, GIP and GLP-1 receptors, and to their use in the treatment of metabolic disorders.
looking also for the possibility of finding a combined glp-1/gip receptor agonist. in this framework, the novel dual gip and glp-1 receptor agonist tirzepatide seems to be not just a new antidiabetic medication. administered as a subcutaneous weekly injection, it is a manifold single pharmacol...
closure and cell depolarization. Because fructose elicits GLP-1 secretion without simultaneous release of glucagonotropic GIP, the pathways underlying fructose-stimulated GLP-1 release might be useful targets for type 2 diabetes mellitus and obesity drug development....
These studies highlight the clear, and persistent, metabolic advantages of sustained activation of GLP-1 receptors, alongside concurrent activation of related GIP and xenin cell signalling pathways, in diabetes.Craig, S. L.Perry, R. A.Vyavahare, S. S.Ng, M. T.Gault, V. A.Flatt, P. ...
The other major incretin hormone, glucagon-like peptide-1 (GLP-1), exhibited no significant effects. Chronic elevation of circulating GIP levels in the Vancouver Diabetic Fatty (VDF) Zucker rat resulted in increases in circulating resistin levels and activation of p38 MAPK or SAPK/JNK in ...
However, dose-related gastrointestinal effects limit efficacy, and therefore agents possessing GLP-1 pharmacology that can also target alternative pathways may expand the therapeutic index. One approach is to engineer GLP-1 activity into the sequence of glucose-dependent insulinotropic polypeptide (GIP)....
