Now scientists have uncovered a new activity for this drug
This centrally produced GLP-1 reaches specific receptors located in key structures involved in appetite regulation, such as the paraventricular nucleus, the lateral septum, the nucleus accumbens and the lateral parabrachial nucleus.2,3,6 Furthermore, it promotes aversive responses, inhibits neuroinflammation and gastric emptying, and stimulates sympathetic tone and thermogenesis in experimental models.2,4,6 Activation of GLP-1R on neurons in the arcuate nucleus stimulates the production of pro-opiomelanocortin (POMC), which in turn inhibits neurons that produce neuropeptide Y (NPY), thereby generating an appetite-suppressing response.2 GLP-1 production has also been reported in the olfactory bulb, although its significance remains unclear.2,6 GLP-1R has been identified in the sinoatrial node, atrial and ventricular myocytes, and vascular endothelium
Cancer cells were grown in medium with 13 C-cystine and then switched to cystine-free medium with unlabelled GSH (Fig
People taking GLP-1 drugs often talk about "food noise" vanishing: the constant mental chatter about food that dominated their days simply goes quiet
