How are antifungal usage and environment change on our farms driving cross-resistance in clinical pathogens?

Fungal pathogens cause deadly human infections, destroy our crops, and contaminate our food with toxins. Fungal pathogens of people are also present on our farms. Worryingly, we rely on a few antifungals to cure human infection and to secure our safe food supply. Here, we aim to understand how our changing environments and use of antifungals on farms may drive human pathogens to evolve cross-resistance to clinical treatments that result in poor patient outcomes.

Targeting adipose – derived adipsin for the treatment of arthritis

Adipose tissue is much more than an energy store. Recent evidence from rodent models indicates that a major product of adipose tissue (adipsin) plays a direct role in the pathogenesis of immune mediated inflammatory arthritis. This interdisciplinary project will determine the role of adipsin in humans, including whether targeting adipsin has the potential to prevent and/or treat inflammatory arthritis and osteoarthritis.

A novel, bacterial quorum sensor-infused nanocarrier drug delivery system to tackle antimicrobial resistant fungi

The lack of effective drugs to manage deadly fungal infections in immunocompromised patients emphasised the dire need for novel therapeutics in combating healthcare associated infections (HAI). Using cutting-edge microbiological and drug delivery approaches, this project will probe the potential for bacterial chemical signals to eliminate invasive fungal pathogen, Candida. Findings will establish a prototype of a novel therapeutic alternative to fight fungal HAI.

Investigating senescence in osteoarthritis 

The accumulation of senescent, ‘zombie’ cells cause tissue dysfunction and human disease including osteoarthritis (OA). This PhD project will investigate how growth, metabolism, and survival pathways are different between senescent and healthy cells. We will then explore how senescence contributes to OA pathology and whether we can prevent or reverse it.

Accelerated prediction of virulence and antibiotic susceptibility for bacteria causing bloodstream infections using MALDI clinical diagnostics

In life-threatening infections, timely and appropriate antibiotics improve outcomes but testing for antibiotic sensitivities is slow. Our novel machine learning helps detect bacterial types associated with enhanced virulence and resistance from routine MALDI mass spectrometry data. You will develop and validate this approach for clinically-important Klebsiella pneumoniae and Escherichia coli additionally performing gene knockout experiments and bioinformatics.

Identifying immune mechanisms and testing new therapeutic targets for inflammatory arthritis and associated comorbidities

Cytokine-blocking drugs have revolutionised the treatment of inflammatory arthritis. However, ~40% of patients show poor responses to these drugs, continue to display severe disease and also suffer comorbidities (e.g. cardiovascular disease, uveitis). The student will use in vivo arthritis models, imaging, and bioinformatics to test the therapeutic potential of targeting coexisting immune mechanisms active in arthritic joints and tissues affected by comorbidity.

Immune and therapeutic implications of intratumour bacteria

Intratumour microbiota (i.e. bacteria living inside tumour cells) is an emerging hallmark that has been clinically validated in many tumour types. You will study the role of intratumour microbiota in promoting chemoresistance and characterise the associated tumour immune microenvironment. Once validated, this project will be the first demonstration of how intratumour microbes alter tumour behaviours, paving the way to more mechanism-directed clinical interventions.

Sticky but not sweet: deciphering how Streptococcus bacteria drive clot formation and heart disease

Streptococcus bacteria cause heart disease infective endocarditis (IE), for which novel therapies are urgently needed. Bacterial protein PadA is critical to IE pathogenesis but how it functions is unknown. This project combines molecular/clinical microbiology, host immunity and structural biology to identify the mechanisms by which PadA aids bacterial survival in blood and drives the harmful clot formation seen with IE. Such insight is critical to IE therapy design. Dr Angela Nobbs

Understanding how extracellular vesicles influence inflammation during tissue regeneration in zebrafish

Zebrafish have a remarkable ability to regenerate damaged tissues. Tissue repair and regeneration requires communication between multiple different cell types including immune cells, fibroblasts and endothelial cells. Extracellular vesicles (EVs) deliver molecular messages between cells and our data suggests they promote regeneration. This project will determine how EVs might be harnessed to facilitate optimal repair of damaged tissues via influencing inflammation.

Exploiting glycan interactions for bacterial detection

Bacterial infections acquired in the community (e.g. tuberculosis (TB)) or healthcare settings (e.g. Staphylococcus aureus/MRSA) are a global public health burden exacerbated by growing antimicrobial resistance and slow antimicrobial drug development. Bacteria exploit specific carbohydrates (glycans) during the infection process. This project explores how bacteria interact with synthetic glycans, and how these might be developed as tools for detecting infections.

Does microplastic exposure cause immune dysfunction and impact our health?

Humans are estimated to consume millions of microplastics (MPs) each year, but exactly how MPs impact our health is alarmingly unclear. In this project, we will identify the molecular consequences of MP uptake on cells and tissues, and explore whether prolonged MP exposure even weakens immunity. We will integrate in vivo animal models with in vitro analyses of human cells and state-of-the-art imaging, and engage with chemists to test novel bioplastic alternatives.

Investigating novel chronic kidney disease therapies that regulate expression of long noncoding RNA hyaluronan synthase 2-antisense 1 (HAS2-AS1)

Chronic kidney disease (CKD) affects 15% of the global population but has no cure. This project will investigate a novel therapeutic approach to halting CKD progression, by using a long noncoding (lnc)RNA that is relevant to kidney disease. The student will explore the role of lncRNA HAS2-AS1 in the regulation of kidney fibrosis using cell and in vivo models, and then translate these findings by manipulating HAS2-AS1 expression in models of CKD therapy.

Novel tools for analysis of high-dimensional cytometry data: implications for patients with severe dengue

Cytometry – the method of identifying and counting cells – is a cornerstone of biomedical research and clinical practice. Cytometry generates massive datasets too unwieldy to manage efficiently, thereby slowing down scientific progress. We aim to empower scientists to analyse and interpret complex data at a quality, speed and reproducibility never seen before, by developing novel mathematical approaches and apply them to immune profiles of dengue patients.

T cell immune modulation during severe bacterial infection

There is no licensed vaccine against Staphylococcus aureus which produces life-threatening bloodstream infections (“bacteraemia”) and has evolved antibiotic-resistant strains. However, mucosal-associated invariant T (MAIT) cells can combat certain antibiotic-resistant bacteria, positioning them as ideal targets for new vaccines. The student will examine how MAIT cell responses against Staphylococcus aureus are affected by the bacterium during bacteraemia.

Defining the adenoviral “interactome” to develop safer and more efficacious virus-based therapies

The AZ adenovirus-based coronavirus vaccine has prevented ~6M COVID deaths worldwide. Nevertheless, interactions with host proteins have resulted in rare adverse blood clotting events, harming vaccine confidence. This highlights the need to define proteins interacting with adenoviruses prior to clinical role out. This project will develop methodologies to achieve this, defining the viral “interactome” to develop safer platforms for therapeutic applications.

Epigenetic regulation of microglial gene expression in Alzheimer’s disease

Neuroinflammation is a prominent event in Alzheimer’s disease (AD) pathogenesis driven by activation of microglia, the brains resident immune cells. To define how microglial gene expression is regulated in AD, this project utilises a state-of-the-art human induced pluripotent stem cell models of AD coupled with epigenomic profiling and bioinformatic analysis. The role of prioritised genes will then be described through functional assays of key microglial processes.

De novo synthekines for treatment of autoimmune diseases

Inflammation is essential for responding to infection and tissue damage. Its dysregulation, however, causes autoimmune diseases and chronic inflammation. Modulating cytokine activity has emerged as an important therapy for autoimmune conditions such as rheumatoid arthritis and uveitis. In this project you will computationally design new-to-nature proteins that mimic cytokines and test their therapeutic potential in autoimmunity.

Enhancing immunological control of SARS-CoV-2

Neutralizing antibodies are key to preventing transmission of SARS-CoV-2, however the virus can rapidly mutate to avoid these. Furthermore, once infected, neutralizing antibodies cannot access intracellular virus. At this point, antibodies that recognise the infected cell become critical. However, current vaccines fail to induce these. This proposal will investigate how this activity can be induced, as the basis for next-generation and variant-resistant vaccines.

Generating killer cells for immunotherapy against cancer and pathogens

Natural killer cells (NK) and CD8+ cytotoxic T lymphocytes (CTL) protect us by killing cells infected with intracellular pathogens and cancers. This project aims to work out what drives the growth of types of NK and CTL that are optimised to protect against these diseases, using state-of-the-art technologies (proteomics, advanced flow cytometry), unique libraries of viruses (adenovirus and cytomegalovirus) and clinical samples (leukaemias) as systems of analysis.

Investigating the therapeutic potential of microwaves in chronic wound healing

Chronic wounds are a significant economic and societal burden. Bacterial biofilms are regular colonisers of chronic wounds, with treatment failure common. Microwaves will be investigated as a potential therapy for chronic wounds via a dual approach of biofilm disruption and promoting healing through fibroblast stimulation. A clinical prototype will also be designed based on patient feedback and an interdisciplinary skillset will be developed.

Optimising phage cocktails for treatment of drug resistant pathogens associated with cystic fibrosis

Phage cocktails promise treatments for antibiotic-resistant infections but are arbitrarily composed. They do not account for phage cross-resistance (resistance to one phage confers resistance to others), especially alongside antibiotics or immune responses. Using new high-throughput phage resistance assays and genomics the student will deliver phage cocktails that avoid cross-resistance and maximise effect in combination with antibiotics and innate host immunity.
