Insights That Move the GPCR Field Forward

Before the islet lit up, the collaboration wasn’t even aimed at imaging. Johannes “JB” Broichhagen trained as a synthetic chemist — someone who trusted carbon–carbon bonds far more than live-cell behavior. Yet curiosity and chemistry pulled him into the world of GLP-1R, pancreatic β-cells, and the biological questions David Hodson had been exploring for years. The call from David — the glowing islet — created a pivot the team couldn’t ignore. A fluorescent peptide probe
