Mauro, Claudio

Reader in Metabolism and Inflammation / British Heart Foundation Research Fellow

I graduated from the University of Naples “Federico II” (Italy) with a degree in Medical Biotechnology in 2002 and a PhD in Molecular Oncology and Endocrinology in 2007.

During my PhD (2002-07) I studied the pro-inflammatory and anti-apoptotic response controlled by the NF-kappaB family of transcription factors. In these studies I discovered novel mechanisms of activation of NF-kB downstream of TNF receptors and upon endoplasmic reticulum stress and the contribution of NF-kB activity to thyroid tumourigenesis (Biochem Biophys Res Comm 2003, J Biol Chem 2004, J Biol Chem 2006a, J Biol Chem 2006b, J Neurol Neurosurg Psychiatry 2008).

During my postdoc (2007-11) – supported in part by an Immediate Fellowship from the Italian Association for Cancer Research – I worked both at the University of Chicago (USA) and Imperial College (UK) at the identification of the molecular links between inflammation and metabolism in the adaptive immune system and in cancer (Proc Natl Acad Sci 2010, Nat Cell Biol 2011).

Since I moved to the William Harvey Research Institute in 2011, I focused on the investigation of the metabolic control of immune cell effector functions and the implications of the metabolic dependence of immune responses during inflammation. This work led to the award of a prestigious Intermediate Basic Science Research Fellowship from the British Heart Foundation in 2012 and the publication of a number of papers in the field (Mol Cell Proteomics 2014, PLoS Biol 2015, Trends Biochem Sci 2016, Eur J Immunol 2016, Cell Metab 2017, Nat Comm 2017). 

Summary of Research

My focus is on the interconnections between metabolic and inflammatory pathways. We are investigating the hypothesis that systemic metabolic alterations in cardiovascular and autoimmune disease lead to aberrant immune cell responses and migration patterns, which favour the establishment of chronic inflammation. Our studies indicate that interfering with metabolic pathways (i.e., lipid, glucose and oxidative metabolism) alters immune cell effector functions (PLoS Biol 2015, Cell Metab 2017, Nat Comm 2017). In particular, we are focusing on the mechanisms of metabolic control of T cell-mediated immune responses, including migration, differentiation and cytokine production in physiology and under metabolic stress. These studies are providing insights into the role of energy balance on physiologic T cell-mediated immune responses and the effect of altering metabolism on the development of T cell-mediated inflammation, as well as new therapeutic targets to prevent inflammation in these human conditions.
