Hypoxia-driven macrophage modulation in cancer and its impact on T cell immunotherapy

Hypoxia is a common feature of solid tumours. It presents a significant challenge to effective cancer treatment using immunotherapy.

Macrophages are known to be recruited to hypoxic regions of the tumour and undergo polarisation to an M2 pro-tumorigenic phenotype. This phenotypic shift can substantially impact the efficacy of T cell immunotherapy.

The aim of this PhD project is to evaluate the role of hypoxia in modulating macrophage function during tumour progression. Cutting-edge platforms for single-cell and whole-body imaging, immuno-profiling and transcriptomic analysis will be employed to examine the spatial and dynamic changes in tumour hypoxia, macrophage function and their interactions with T cells within hypoxic niches.

Tumour spheroid models and preclinical immuno-oncology mouse models will be established to evaluate these mechanisms. Treatment strategies will be developed to target hypoxia and macrophage-mediated immunosuppression in cancer.

Supervisor's interests

Immunotherapy has revolutionised cancer treatment. Various interventions such as immune checkpoint inhibitors, cancer vaccines and engineered chimeric antigen receptor T cells, have been developed over the years to enhance anti-tumour immunity.

Despite the increasing adoption of immunotherapy in routine clinical practice, only a minority of patients benefit from treatment, and autoimmune side effects may occur in some patients on systemic therapy.

Several factors like immunogenetics, cancer types and stages, and underlying tumour immunobiology, play a crucial role in determining response to immunotherapy. There is a need to understand the mechanisms involved in anti-tumour immunity and treatment resistance to improve the outcome of immunotherapy.

Doreen Lau - Dr Doreen Lau is a Lecturer at Brunel University London, and a visiting researcher at University of Cambridge. She graduated with a PhD from the University of Cambridge as a Cancer Research UK and Cambridge Trust scholar, focusing on cancer immunology and the clinical translation of molecular imaging techniques and biomarkers for cancer immunotherapy in patients and preclinical models. She received postgraduate training in cancer imaging and pharmacology at Imperial College London, and was a former scientist at the University of Oxford and the Agency for Science, Technology and Research (A*STAR) Singapore. She was previously a part-time Lecturer in Oxford teaching imaging, disease mechanisms and therapy in cancer, and was the Module Co-lead for cancer immunology. Dr Lau was the recipient of several international prizes for her work in immuno-oncology imaging and experimental medicine. These include the 1st Place William G. Negendank Young Investigator Award by the International Society for Magnetic Resonance in Medicine for cancer imaging (2018), Women in Molecular Imaging Network Scholar Award by the World Molecular Imaging Society (2019), Top 3 PhD Award by the European Society for Molecular Imaging (2021), and the Merit Travel Grant and Best Poster Award in Immuno-oncology Biomarker Development by the European Society for Medical Oncology (2023). In recognition of her achievements as a young scientist, she was awarded a Junior Research Fellowship in Sciences in 2022 from Wolfson College, University of Oxford.
