From Diabetes to Liver Disease: The Expanding Role of GLP-1 Receptor Agonists

April 2, 2025

Abstract Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are revolutionizing the management of metabolic diseases, offering powerful benefits that extend far beyond glucose control. Originally developed for type 2 diabetes, GLP-1RAs have demonstrated significant advantages in promoting weight loss, reducing cardiovascular risk, and now, treating liver conditions such as metabolic dysfunction-associated steatohepatitis (MASH). Backed by robust clinical […]

Beyond Serelaxin: Engineering Durable RXFP1 Agonists for Next-Generation Cardiovascular and Renal Therapy

April 2, 2025

Abstract Relaxin-2, a hormone with well-documented roles in vascular and renal physiology, has demonstrated therapeutic potential in acute heart failure and renal dysfunction. However, the clinical utility of serelaxin, its recombinant form, is hindered by a short half-life and intravenous delivery requirements. R2R01, a novel single-chain peptide agonist of RXFP1, was developed to address these […]
