I first became captivated by the complexities of cellular signal transduction pathways during my undergraduate biochemistry degree at Trinity College Dublin, which led me to a PhD at the University of Dundee investigating roles for protein kinases such as mTORC1 in the control of metabolic pathways in hepatocytes. I retained a keen interest in protein kinase signalling during my postdoctoral research in Prof. Doreen Cantrell's lab at the University of Dundee. It was during this time in I realised that mTORC1 is a key regulator of CD8 T cell biology largely because it controls cellular metabolic pathways. This research led to one of the first publications in the then emerging field of immunometabolism and motivated me to establish my independent research group to further explore how cellular metabolism is linked to the control of immune cell fate and function. Since 2011, I have secured in excess of €3.4 million research funding and my research has contributed significantly to the current understanding that cellular metabolism is integrally linked to immune cell functions. My research is at the forefront of the Immunometabolism field and I have published high impact studies that have challenged established dogmas. My research group was the first to characterize cellular metabolic pathways in Natural Killer cells to show that the way they metabolize glucose is different to the metabolic pathways described in biochemistry textbooks (Journal of Immunology 2014, Nature Immunology 2017, Nature Communications 2018). My research has also made key contributions to an emerging idea that nutrients are more than just fuels and function as important signals; we showed that glucose controls signal transduction pathways in Dendritic cells (DC) to inhibit DC functions and to limit the induction of CD8 T cell responses (Nature Communications 2017). My contribution to leading this new field of immunometabolism have been recognised with invitations to write review articles for high impact journals including the Journal of Clinical Investigation (2016), Seminars in Immunology (2017) and Nature Reviews Immunology (2019, which have been well received and highly cited. In 2017 I secured an ERC Consolidator Award to study nutrients as key determinants of DC-induced CD8 T cell responses. Successful implementation of this ERC research programme will open new horizons for the study of nutrients as determinants of immune responses. Based on my expertise in the area of lymphocyte metabolism, it is my ambition that this ERC research programme will lead me to further ground-breaking studies assessing the role for nutrients in controlling T cell and NK cell responses in diverse inflammatory situations.

Our immune system is important for our health protecting us from infection/cancer, but inappropriate immune responses cause us harm. Diverse diseases could be treated through therapeutic manipulation of our immune systems. My research group wants to understand how to control immune cells and is now revealing the importance of cellular metabolism. We are revealing novel strategies to modulate immune cell function through targeting cellular metabolism and new therapeutic opportunities are being explored. Our data show following activation Natural killer (NK) cells, lymphocytes with important anti-cancer and anti-viral functions, undergo robust metabolic changes. We have identified the key metabolic regulators of this metabolic response to be mTORC1, cMyc and Srebp. Directly disrupting metabolic pathways in NK cells or interfering with the function of these metabolic regulators severely inhibits NK cell anti-cancer and anti-viral functions, including target cell killing. We are exploring how NK cell metabolism might be manipulated to improve NK cell-based anti-cancer immunotherapies through a Enterprise Ireland Innovative partnership with a Galway-based company ONK Therapeutics. In contrast to lymphocytes, mTORC1 and glucose metabolism actually inhibit the function of Dendritic Cells (DC). We made the novel discovery that starving DC of glucose results in increased proinflammatory outputs and enhanced DC-induced T cell responses. This study highlights the complex relationship between nutrient availability and the induction of immune responses. An important next step will be investigating the distribution of nutrients in vivo, to determine which immune cells are nutrient replete and those that are deprived of nutrients. Ongoing projects include: --Investigating nutrients as key determinants of DC-induced CD8 T cell responses (funded by ERC-CoG) --Characterising how the tumour microenvironment disrupts NK cell metabolism towards engineering NK cells for improved metabolic resilience and improved met to improve anti-tumour NK cell therapies.(funded by Enterprise Ireland and ONK Therapeutics)
