To characterize how the interplay between cancer cells, CAFs, cancer-associated adipocytes, and macrophages influences the anti-tumour immune response. To evaluate how metabolic diseases (such as obesity) can shape the tumor microenvironment and alter the sensitivity to viral therapeutics. To unveil and characterize the putative function of RNA interference (RNAi) as an antiviral innate immune mechanism in cancer cells.

Therapeutic viruses have been gaining momentum both pre-clinically and clinically as promising multi-modality anti-cancer platforms. Several viruses have been successfully engineered to selectively replicate and kill cancer cells, thereby rendering them oncolytic (onco = tumor; lytic = killing). However, a tumour is more than a collection of malignant cells. The tumour microenvironment also contains cancer-associated fibroblast (CAFs), fat cells (cancer-associated adipocytes), vascular endothelial cells, immune cells and the extracellular matrix that binds them all together. The overarching hypothesis of my research is that the tumour microenvironment as a separate but integral cancer-associated entity that (1) may be targeted by oncolytic viruses (OVs) and that (2) may modulate the therapeutic outcome of viroimmunotherapy. Dissecting the interplay between different cellular components of the tumour microenvironment and their role in innate and acquired resistance to virus-based therapies will enable us to design highly targeted and effective OVs. As an example of this type of approach, we have recently identified that CAFs play a central role in modulating the sensitivity of the tumor cell compartment to OV infection and cell killing. In order to capitalize upon this, we have engineered the key molecule mediating this effect, fibroblast growth factor 2 (FGF2), into the genome of the oncolytic virus MG1. We have demonstrated both in vitro and in vivo that this virus has an increased capacity to replicate in cancer cells and leads to improved therapeutic outcomes in murine models.
