Arjun Deb

Dr. Arjun Deb is a Professor in the School of Medicine at the University of California Los Angeles (UCLA), specializing in cardiovascular biology, cardiac repair mechanisms, and SARS-CoV-2 pathophysiology. He serves as Principal Investigator for multiple NIH grants, including R01HL152176 (GPNMB in Cardiac Remodeling) and R01AR075867 (Pseudoxanthoma Elasticum). His research focuses on Wnt/β-catenin signaling, collagen dynamics, and metabolic reprogramming in cardiac injury.

• Major Contributions: Discovery of collagen V's role in kidney repair, GPNMB-GPR39 cardiac repair pathways, and SPOT imaging technology for sub-cellular biomechanics
• Key Collaborations: Matteo Pellegrini (UCLA), Aldons Lusis (UCLA), Tomohiro Yokota (UCLA), Vaithilingaraja Arumugaswami (UCLA)

His recent publications (2023-2025) reveal trends in Science Translational Medicine, Nature Cardiovascular Research, and Cell Stem Cell, emphasizing cardiac fibroblast plasticity, microbiome-heart interactions, and novel therapeutic strategies. Over 20 years, he has mentored multidisciplinary teams in cardiac regeneration, vascular disease, and viral pathogenesis, with significant impact in cell-cell communication, epigenetic changes, and collagen-based therapies. His work appears in 281 news outlets and has been cited over 3,000 times in PubMed Central.
