Tumour-activated cancer immunotherapies
Solid tumours create an immunosuppressive microenvironment that limits the efficacy and safety of current immunotherapies, often leading to poor efficacy and off-target toxicity. This project aims to engineer next-generation protein and cellular therapies that are triggered by tumour-restricted signals such as hypoxia, acidic pH, or matrix metalloproteinase activity. Using our directed evolution and rational protein design platform, you will develop and test novel therapies in cell-based models, then evaluate them for safety and therapeutic benefit in mouse models of solid cancer. The goal of this research is to identify the most promising tumour-activated immunotherapies, laying the groundwork for more potent and less toxic cancer treatments.
Enhancing the durability of stem cell-derived islets for type 1 diabetes
Type 1 diabetes (T1D) results from the autoimmune destruction of insulin-producing beta cells, requiring continuous management of blood sugar levels. A lifelong cure for T1D will require regeneration or replacement of these cells. This project focuses on the transcription factor PDX1, which is a master regulator of pancreatic cell fate and is also essential for promoting optimal beta cell function. Excitingly, PDX1 both promotes regeneration and is critical for converting other pancreatic cell-types into beta cells. Our team uses directed evolution to engineer novel proteins in cells that model human disease. We have developed PDX1 variants with new properties that could enhance the function of stem cell-derived islets, which are the only renewable source of beta cells for curing T1D. The goal of this project is to determine which variant has the most potential for increasing the durability and function of transplanted islets, setting the stage for clinical translation.
Novel delivery systems to empower complete repair after a heart attack
Myocardial infarction (heart attack) results from the sudden loss of blood flow to cardiac tissue, causing massive cell death and subsequent scar formation that impairs pump function. Current clinical interventions stabilise patients and limit further damage but cannot regenerate lost heart muscle. This project targets that unmet need by engineering protein therapeutics and delivering them at the optimal time and place to maximise heart muscle survival, proliferation, and function. Using our directed evolution and rational design platform, we have generated lead protein candidates. The aim of this research is to deliver these candidates to human cardiomyocytes in culture and eventually to animal models to empower regenerative responses.
