Margherita Bertuzzi is a molecular microbiologist specialising in fungal infection biology, whose research focuses on the antifungal phagocytic activities of the respiratory epithelium in health and disease.

With a major emphasis on pH-mediated signalling, her research has focused upon the way in which extracellular cues shape fungal tissue invasion and pathogenicity in mammalian hosts. During her PhD at Imperial College London (2007-2011), she developed the first, and only, protein-protein interaction toolkit for the major mould pathogen of human lungs Aspergillus fumigatus, demonstrating that a non-redundant pH sensor initiates pH signalling, which is critical for pathogenicity. This work [Bertuzzi & Bignell, Fungal Biology Reviews, 2011] has fuelled the exploration of fungal pH signalling as a drug target.

As a Postdoctoral Scientist at Imperial College London first (2011-2014) and then at the University of Manchester (2014-2017), she developed the first genetically-encoded biosensors of calcium signalling in A. fumigatus [Muñoz* & Bertuzzi*, et al., PloS one, 2015], which will facilitate discovery of new antifungal drugs. Furthermore, she demonstrated that A. fumigatus alkaline and calcium signalling, both critical for pathogenicity, have evolved to function independently, having important implications for antifungal drug discovery [Loss* & Bertuzzi*, et al., Molecular microbiology, 2017]. Also, she demonstrated that fungal invasion of the mammalian lung is genetically regulated [Bertuzzi*, et al., PLoS pathogens, 2014] and that uptake of fungal spores by the respiratory epithelium is one of the earliest events in the host-pathogen interaction.

As a Research Fellow at the University of Manchester (2017-2020) , she established novel single-cell approaches to demonstrate that phagocytic activities of cultured human airway epithelial cells directly and competently promote clearance of infecting fungal spores [methods chapters in Methods Handbook on Host-Fungal interactions, in press].  As an early career scientist developing an independent career in single cell technologies, she was awarded an MRC Discovery award from the University of Manchester (2017) to substantiate her results using clinical samples, thanks to an established collaboration between the Collaborative Centre for Inflammation Research (MCCIR), the Manchester University NHS Foundation Trust (Wythenshawe) and the National Aspergillosis Centre.

She was appointed Lecturer in Molecular Microbiology at the University of Manchester in 2020 to establish her research group, focusing on understanding epithelial encounters with inhaled respiratory pathogens and the role of these events in health and disease, especially in chronic obstructive pulmonary disease (COPD), a well-known risk factor for debilitating fungal lung disease. Having been awarded a prestigious MRC New Investigator Research grant in 2021, her group is now pursuing a full mechanistic understanding of fungal-epithelial interactions and how these are dysregulated in disease. In 2025, in collaboration with Dr Becky Hall at the University of Kent, she secured funding from the Wellcome trust to investigate how Mucorales adaptation to natural and in-host environments underpins Mucormycosis infection.

Dr Bertuzzi’s research focuses on the epithelial interactions with inhaled respiratory pathogens and the role of these events in health and disease, how these interactions affect communication with other components of human immune and inflammatory cascades, and the technical know-how to translate this knowledge into human benefit.

As fungal spores represent a major component of the multitude of noxious inhaled particles continually assaulting human lungs, the research in her group is directed to obtain first-in-field mechanistic insights into curative and dysfunctional epithelial responses following uptake of fungal spores, in particular of the fatal, environmental mould Aspergillus fumigatus and Mucorales.

To acquire a full mechanistic understanding of fungal-epithelial interactions and how these influence immune responses and are dysregulated in disease, her group exploits single-cell technologies and molecular, transcriptional and immunological analyses of the fungal-AEC interaction in vitro, ex vivo and in primary AECs from at-risk patients.

Dr Bertuzzi is committed to the delivery of exceptional undergraduate and postgraduate teaching, in alignment with her research and knowledge of infection biology and microbiology. She is currently the Co-Director of the MSc Infection Biology programme, a novel research-focused 12-month full-time course (established in 18/19), which consolidates the interdisciplinary network of excellence in fundamental and clinical infectious diseases research at Manchester. Within the programme, she also leads the Host-pathogen interaction lecture unit and the Research Project II unit.

In the years, she has acquired experience in a range of delivery techniques by delivering cellular and molecular mycology lectures and technology workshop, chairing Journal clubs, acting as a facilitator of UGT Medical PBL sessions and Biosciences tutorials, acting as an academic mentor for PGT students and supporting UGT and PGT research projects.
