Researchers from the Biomarkers of Cardiovascular Disease Progression group at the Institut de Recerca Sant Pau (IR Sant Pau) have identified a new mechanism by which complement C3, a key immune system protein, can directly influence the progression of atherosclerosis. The study, published in the journal Cells, shows that activation of this molecule alters the structure and behavior of the cells that form the arterial wall, contributing to lesions becoming more unstable and more prone to rupture.

A team from the Sant Pau Research Institute (IR Sant Pau) has discovered that basic fibroblast growth factor (bFGF) can reverse the functional impairments of adipose tissue–derived stem cells in people with type 2 diabetes. This restores their ability to proliferate, migrate, and form new blood vessels.
