About the Cardiovascular Inflammation and Redox Biology laboratory
Research in the Cardiovascular Inflammation and Redox Biology laboratory focuses on improving the lives of people with diabetes by reducing the burden of cardiovascular disease.
By identifying novel therapies aimed at lowering both inflammation and oxidative stress, our research is opening new areas for drug discovery. These preclinical studies represent crucial first steps in understanding how to better tackle the complications that arise from this fast-growing health issue, particularly given the obesity epidemic and its link to type 2 diabetes.
Understanding inflammation and oxidative stress in diabetes
Our research seeks to define how inflammation and oxidative stress drive the development and progression of diabetes-associated cardiovascular diseases. We investigate the cellular and molecular mechanisms that link metabolic dysfunction to activation of innate immune pathways, focusing particularly on chronic low-grade inflammation, dysregulated redox balance, and immune cell reprogramming.
By dissecting key signaling networks, including the NLRP3–Gasdermin D inflammasome axis and NRF2-mediated antioxidant responses, we aim to understand how these pathways shape immune metabolism, promote adverse vascular remodeling, and influence immune cell colonisation within cardiovascular tissues. Through this mechanistic insight, our goal is to identify precise targets for therapeutic intervention that can prevent or attenuate cardiovascular complications in diabetes.
Tackling vessel re-closure after stenting
Another interest of our laboratory centres on understanding the mechanisms behind vascular remodelling (restenosis) after balloon angioplasty and stenting. Diabetic patients face a four-fold increased risk of vessel re-closure after coronary artery stenting.
Current drug-eluting stents (DES) indiscriminately inhibit all cell growth. Our unique approach encourages endothelial cell growth — which helps healing — whilst limiting smooth muscle growth and the attachment of inflammatory cells to stent surfaces. Together with Swinburne University, we're trialling new stent coatings in in vitro and in vivo models.
