Dr Erin Aldera – Post-Doctoral Scientist

Erin pursued both her undergraduate and postgraduate studies at the University of Cape Town, graduating with a BSc specialising in Physiology and Microbiology in 2011, BSc (Med)(Hons) in 2012 and PhD in 2018. For her doctoral studies she investigated early-life immunity and the susceptibility of children to mycobacteria by relating vaccine- and helminth-specific antibody responses to their mycobacterial infection outcome. Erin joined the O’Shea group in early 2019 as a Newton International Fellow. Erin is examining the role that helminth-induced eosinophils play in the host immune response to mycobacterial infection by exploring whether these innate cells (classically linked to helminth infection control) can inhibit mycobacterial growth and the mechanisms used.

Charlotte Jones – Senior Laboratory Technician

Charlotte joined the O'Shea group in August 2016, after working for Professor Adam Cunningham on immune responses to Salmonella Typhimurium. Charlotte's background is in microbiology after graduating from the University of Birmingham in Cell and Molecular Biology (BMedSci, 2010). As she has always enjoyed studying, Charlotte undertook a Masters of Biomedical Science by flexible learning with Nottingham Trent University in 2015, graduating in 2017. Since her graduate degree, she has developed an interest in Mycobacterium tuberculosis, particularly the immunological relationship between latent infection and active disease. Charlotte was thrilled to take her current position to study this area using clinical samples and a variety of laboratory techniques (e.g. ELISAs, ELISpot/FluoroSpot, flow cytometry and BACTEC MGIT system).

Dr Danai Papakonstantinou – PhD Student

Danai graduated from the Medical School of the University of Athens (Greece) with an MD in 2005 and went on to complete a Master’s Degree and the Diploma in Tropical Medicine (DTM&H) at the London School of Hygiene and Tropical Medicine (2008-2009). Danai has worked as a medical doctor in Greece and the UK for more than 10 years and specialises in Infectious Diseases and General Internal Medicine in the West Midlands. Danai holds an honorary contract with Heartlands Hospital (Birmingham) as a Senior Registrar in Infectious Diseases and holds a specialty certificate in Infectious Diseases (British Infection Association and Royal College of Physicians). Danai is currently a PhD student in the O’Shea group (co-supervisors Professor Alan McNally and Professor Adam Cunningham) and holds a Global Challenges Scholarship (University of Birmingham). Danai is using bioinformatics to study the Mycobacterium tuberculosis genome to identify novel TB vaccine candidates and antigens for TB diagnostics.

Dr Gabby Morley – PhD Student

Gabby graduated from the University of Birmingham in 2015 with Honours in Medicine and Surgery (MBChB Hons). Through her work as a medical doctor, she developed a keen interest in infectious diseases, however seeing first-hand how certain infections were becoming more challenging to treat due to the rise of antimicrobial resistance. This interest led Gabby to apply for the Wellcome Trust Antimicrobial and Antimicrobial Resistance Doctoral Training Programme and start work in Dr Matt O’Shea’s group, at the University of Birmingham, investigating human immune responses to Mycobacterium tuberculosis (M.tb; co-supervisor Professor Adam Cunningham). Gabby's work aims to increase understanding of the human-M.tb interaction, with particular emphasis on the humoral response to M.tb, to facilitate novel management strategies for tackling drug-resistant M.tb.

Lay summary

Our work aims to understand how the human immune system responds to infection with Mycobacterium tuberculosis. We also study how other pathogens influence this immune response and whether they have an enhancing or diminishing effect. By increasing our knowledge of these processes, we can generate new vaccines and treatments to tackle the huge burden of TB.

Overview 

Mycobacterium tuberculosis (M.tb), the bacterial pathogen which causes tuberculosis (TB), is an ancient disease and the leading cause of death from a single infectious agent globally.  The World Health Organisation estimates that TB accounts for over 10 million new infections and 1.3 million deaths per year. The staggering scale of the TB disease burden is compounded by HIV co-infection and the emergence of multi-, extensively- and now totally-drug resistant strains of M.tb. Furthermore, modelling suggests that almost 25% of the world’s population has latent (dormant) infection, representing a huge reservoir of potential new disease and thus infectiousness.

However, infections rarely occur in isolation and there is significant overlap between M.tb and other endemic diseases in certain regions of the world. For example, one third of the world’s population is thought to be infected with soil-transmitted helminths and the helminth-M.tb co-infection rate is estimated at 20-35% in some low-middle income countries. This highlights that the geographical overlap of these pathogens is not inconsequential and frequently effects very vulnerable individuals. Our current knowledge about how helminths might influence M.tb infection is limited.

It is widely acknowledged that improved diagnostic tests, novel antibiotics and therapeutics are required to tackle the global TB epidemic. While stopping TB transmission with effective anti-tuberculous treatment is one of the cornerstones of TB control programmes, the discovery of a new globally effective TB vaccine remains the most cost effective, long-term control strategy.

Improved understanding of human-M.tb interactions, and the influence of co-infections, will provide opportunities to exploit the immune response to M.tb and therefore has potential translational clinical application through the development of novel diagnostics and therapeutics.

Our research uses clinical samples, in vivo and ex vivo models of infection and a variety of techniques to study immune responses to mycobacteria. While our particular focus is on adaptive immunity, we are also engaged in studying the contribution of innate responses in the control of M.tb.

Some examples of current research themes in the O’Shea laboratory include:

1. How B cell and antibody responses to mycobacterial antigens develop and assessing their role in the control and pathogenesis of M.tb infection.
2. Characterisation of antibody response profiles to proteinaceous and non-proteinaceous M.tb antigens in clinical samples from patients with different forms of TB infection and disease at baseline and in response to therapy.
3. Generating monoclonal antibodies directed against mycobacterial antigens to study their role in modulating responses to M.tb and their application in novel diagnostics and therapeutics.
4. Using computational biology and bioinformatics to identify sub-dominant M.tb antigens as a novel approach to find targets for candidate vaccine development.
5. Understanding the human host immune response across the spectrum of latent infection and TB disease and its relationship to mycobacterial control and pathogenesis.
6. How gastrointestinal helminth infections affect host homeostasis, immune function and the modulation of responses to mycobacteria.
7. Whether helminth-activated eosinophils have an anti-mycobacterial role in the control of M.tb infection.

Our work has shown that patients with active disease have the greatest control of mycobacterial growth in a whole blood mycobacterial growth inhibition assay, whilst there is a continuum of responses among latently infected patients, likely related to the degree of immune activation in response to bacillary load. The improved control we have observed is correlated with multiple factors including inflammatory monocytes, activated and atypical memory B cells, IgG1 responses to M.tb-specific antigens and serum cytokines/chemokines. Our findings are important as they offer a method to stratify subclinical TB infections and the future potential to identify individuals most at risk of progressing to active disease. In addition, we have identified a significant negative association between gastrointestinal hookworm and latent TB infections. Blood from individuals with hookworm have a greater ability to control virulent mycobacterial growth in vitro than from those without, which is lost following hookworm treatment. An eosinophil-associated differential gene expressioncharacterises the whole blood transcriptome of hookworm infection and correlates with improved mycobacterial control. These data suggest a possible anti-mycobacterial role for helminth-induced eosinophils which are investigating further.
