Working with collaborators Antonia Caffery and Ricardo Petrilli Fortuna, Zhang investigated Exendin-Phe (Ex-Phe), a biased GLP-1 … Read More

In August, Rae successfully defended her thesis entitled “Behavioral and Circuit-Level Insights into GLP-1 Receptor Agonist-Mediated Reduction of Drug Seeking”. Since joining the lab in 2019, Rae has consistently produced exceptional and impactful work. She has also been an incredible … Read More

On June 2, 2025, Antonia, Enzo, and colleagues published a study in the British Journal of Pharmacology titled ‘A GLP-1R/Y1 receptor/Y2 receptor triple agonist decreases fentanyl-evoked dopamine release in the nucleus accumbens and attenuates fentanyl taking and seeking in rats’. … Read More

On July 10th, researchers from the Jerlhag and Schmidt laboratories published groundbreaking findings in European Neuropsychopharmacology demonstrating that semaglutide—a GLP-1R medication currently used for diabetes and weight management—significantly reduces cocaine-seeking behaviors in laboratory studies. The study, titled “Semaglutide suppresses cocaine … Read More
