​ 

In 2022, VALIDATE initiated the project: “Develop novel test for PKDL/Leprosy diagnosis”. This project, led by Prof Chatterjee, aims to address the challenge of post-kala-azar dermal leishmaniasis (PKDL) in South-East Asia. PKDL cases can harbor parasites, perpetuating the transmission cycle of the disease. The team plans to develop a field-applicable diagnostic tool, building on a validated isothermal amplification-based assay. Additionally, considering the clinical overlap between PKDL and leprosy, the project includes the development of a combined diagnostic test for both diseases. The ultimate goal is to provide a cost-effective, point-of-care diagnostic tool that can aid in monitoring and treating these neglected tropical diseases, contributing to the Kala Azar Elimination Programme and WHO Global Leprosy Strategy.

In this seminar, Mitali and Ahmed will discuss the PKDL and Leprosy field assays developed by the project and dig into the underlying science.

Dr Ahmed Abd El Wahed, received his PhD in biology from Goettingen University, Germany in 2011. He established a mobile suitcase laboratory for the rapid detection of viruses, bacteria, and parasites. His model has been deployed in several African and Asian countries. He also has a focus on epitope mapping after immunisation and vaccination to identify the best candidate for vaccines using microarrays.

 

Burkholderia pseudomallei, the etiologic agent of melioidosis, causes severe diseases in both humans and animals. Due to its potential misuse as a biological warfare agent, high mortality rates, and resistance to antibiotics, significant efforts have been made in the past decade to develop vaccines against melioidosis. B. pseudomallei produces several polysaccharides on its surface that are important virulence factors and major targets of the immune response. Leveraging their expertise in synthetic carbohydrate chemistry, Charles Gauthier and Maude Cloutier’s group has been at the forefront of developing mimics of the main polysaccharides produced by B. pseudomallei, namely lipopolysaccharide O-antigen (LPS OAg), capsular polysaccharide, and exopolysaccharide.

In this seminar, Charles and Maude describe their endeavor toward the development of semi-synthetic glycoconjugate vaccines against melioidosis, focusing on our most promising results involving B. pseudomallei LPS OAg mimics.

The recent COVID-19 pandemic made it clear that a lot could be gained from decentralised vaccine development. Also, many diseases are localized to Low and Middle Income Countries, especially in tropical regions. However, research in immunobiologicals is costly and requires infrastructure and collaborations that are scarce in poorer countries. In this seminar Breno Beirão explores two important question, how should we tackle this, and if so, how and should we leave it in favour of investing in more basic needs of these poor communities?

Seminar Three took place on Tuesday, December 13, 2023, at 10:00 GMT.

  1. The Role of Vaccination in Controlling Animal TB with Prof. Eamonn Gormley, UCD, Ireland
    In the context of One Health epidemiology for M. bovis infection, managing wild animals' involvement can be challenging, often involving segregation, test-and-cull, or enhanced biosecurity. Vaccination, such as the BCG vaccine, shows promise in reducing tuberculosis burden in wildlife, as seen in badger vaccination in Ireland and the UK. In this talk, Eamonn discusses the challenges of managing wild animals' involvement in the One Health epidemiology of M. bovis infection, highlighting vaccination as a promising strategy, as exemplified by badger vaccination in Ireland and the UK.
  2. Tip of the Iceberg: TB in South African Wildlife with Prof. Michele Miller, Stellenbosch University, South Africa
    Michele provided an overview of TB in wildlife in the South African context. Using a One Health approach, this talk will cover some of the underlying issues contributing to TB presence and spread within wildlife and at human-livestock-wildlife-environmental interfaces.

Seminar Two took place on Zoom, 23 November 2023 at 14:00 GMT.

There were two fascinating talks:

  1. Solutions against infectious diseases in indigenous population: inter-cultural challenges in One Health with Dr Juan Dib, Universidad del Norte, Colombia
    Juan investigates the intercultural challenges in implementing One Health solutions against infectious diseases in indigenous populations. He highlights the fundamental differences in the worldview of health and disease between indigenous societies, which view health holistically, and Western medicine's reductionist approach. Juan also examines the need for improved research efforts and surveillance programmes that are tailored to remote indigenous communities to better identify disease burdens and promote public health action.

  2. Impact and solutions to inequitable health care infrastructure on TB in Madagascar with Dr Niaina Rakotosamimanana, Pasteur Institute of Madagascar. In this talk, Niaina addresses strategies to improve TB care and obtain epidemiological information in remote areas of Madagascar, including the use of new technologies, instructional videos, medication reminders, remote monitoring, and even drones for samples and treatment transportation, all of which aim to enhance patient education, adherence, and symptom monitoring.

Took place online, 15:00 BST, 4 July 2023

 

Two fascinating presentations by two VALIDATE members from St George's, University of London focused on the development of a potential Spore-FP1 vaccine for tuberculosis (TB). Prof Rajko Reljic examined the Spore-FP1 mucosal vaccine candidate based on the fusion protein of Ag85B-Acr-HBHA/heparin-binding domain adsorbed on the surface of inactivated Bacillus subtilis spores. The vaccine candidate demonstrated significant protection in mice and guinea pigs when used as a mucosal boost to BCG but did not improve the efficacy of BCG alone in NHP. Mr Emil Vergara then explored the potential of two subunit vaccine candidates, Spore-FP1 and Nano-FP1, as post-exposure TB vaccines in mice with pre-existing lung mycobacterial immunity elicited with Mycobacterium bovis BCG. Results showed an increasing trend in the frequency of tissue-resident memory T cells, antigen-specific effector CD4 and CD8 T cells, and mucosal and systemic antibody responses among mice that received candidate vaccines.

 

Took place Online, 13:00 BST, 29 June 2023 

In this talk, Dr Yumiko Tsikamoto discussed her innovative research which has led to the development of a recombinant BCG vaccine against Mycobacterium tuberculosis. This novel vaccine features MTB-derived MMP-II and has been further modified by depleting the UreC gene, which stimulates phagosome-lysosome fusion in host cells infected with the recombinant BCG. Yimko will discus results from in vivo experiments that used a mouse model and show that this vaccine inhibits the multiplication of M. tuberculosis in the lungs much more efficiently than the traditional host BCG. Remarkably, the research team also achieved the development of an antibiotics-free recombinant BCG, utilizing cutting-edge auxotrophy-based recombination techniques. These groundbreaking findings represent a major advancement in the ongoing global effort to combat tuberculosis.

In this seminar, Dr Apichai Tuanyok discussed his team’s multidisciplinary research to investigate the epidemiology of melioidosis in southern Thailand. 

The seminar took place via Zoom on 22 February 2023 at 15:00 GMT.

Seminar took Place 14 December - 15:00 GMT

In this seminar, Dr Luciana Balboa will discuss how her team focused on unravelling the immunometabolic pathways that regulates leucocytes’ functions and their impact on the control of TB. To study the impact of TB-associated microenvironment on the functionality of M1 macrophages, they used the acellular fraction of pleural effusions from TB patients (TB-PE). Interestingly, they found that M1 macrophages exposed to TB-PE displayed a lower expression of HIF-1α and a reduced glycolytic activity, impairing the control of the bacterial growth.

 

Seminar took place 16 November 2022 - 15:00 GMT

Antigen-delivery vaccine platforms that promote humoral and cellular responses while maintaining a safe profile are a roadblock to developing subunit vaccines against Burkholderia pseudomallei. The Torres Lab at UTMB has used gold nanoparticles for the delivery of multicomponent antigens, identified by the bio-immunoinformatic analysis, that is able to induce vaccine-mediated immunity, promoting protection against melioidosis disease.

In this talk, Prof Alfredo G Torres discussed his team's latest research on nanovaccines.

BCG is the most studied vaccine and holds promise. Several studies indicate that BCG confers some protection against leprosy. In this talk, Dr Yumi Maeda, of the Leprosy Research Center National Tokyo Institute of Infectious Diseases, Japan, discusses how her team constructed a recombinant BCG that secretes Major Membrane Protein-II of M. leprae, and found that it was effective in inhibiting the growth of M. leprae in mice footpads. Studies are underway to produce BCG that is stable and can be used for large scale preparation.

Detection of leprosy is also necessary for early treatment. From the analysis of the genomic sequence, specific genes coding for antigens of leprosy were selected for evaluating the antibodies in the sera of patients, and user-friendly tools are also being developed.

COVID has provided a stark example of pathogenic mutation. The variation of the impact of infection on the population similarly shows that human responses are variable. This highlights a key need in vaccinology of identifying and developing technologies that can address diversity whilst maintaining safety and achieving cost-effectively. In this session, Graham Clarke explores the options and particularly highlight ImmBio’s approach, exemplified by its lead development against Streptococcus pneumoniae, a good example of a bacteria in circulation with a wide array of genotypes. Whilst there are products available providing good protection against specific serotypes, as defined by the polysaccharide capsule used in the current class of vaccines, ImmBio’s focus is a multiple-protein approach. A new approach raises new regulatory and manufacturing challenges but again drawing on COVID experience, vaccinology may be able to able to benefit from a paradigm shift in addressing risk and benefit, enhancing the attractiveness of investing in new vaccines.

​​​​​​Speaker: Graham Clarke is ImmBio’s Chair and previously its CEO. Originally a biophysicist, he has held senior-level positions including at SmithKline Beecham, GSK and GE Healthcare. He is now a non-executive on a number of boards, including the UK’s Medicine Discovery Catapult and NHS Health Research Authority.

VALIDATE seminar - Developing a better vaccine against TB

This seminar took place 15 February 2019 and was led by Prof Helen McShane and Dr Rachel Tanner.

TB kills more people than any other infectious disease. The efficacy of the only available vaccine, BCG, is highly variable and lowest in high burden settings. The McShane group is developing novel TB vaccine candidates by identifying novel antigenic targets and exploring novel routes of immunization.

TB vaccine development is challenging given the lack of defined immunological correlates of protection. Class II restricted T cells are critical for protective immunity but may not be sufficient. Dr Tanner provided an update on functional mycobacterial growth inhibition assays and on a role for antibodies in protective immunity.

zelmer fletcher seminar

This seminar took place on the 6 December 2017 at LSHTM and was led by Dr Andrea Zelmer and Dr Helen Fletcher, LSHTM.

Immune correlates of risk of TB disease have recently been identified in human clinical trials.  These correlates indicate that, years before TB disease develops, there is alteration in the host-immune environment which is associated with risk of TB disease. Perhaps these alterations render the immune environment permissive to mycobacterial infection or increased growth, or perhaps they reduce the efficacy of the BCG vaccine?  Back translation of immune correlates of risk into animal models will enable us to address these questions and model the immune response of those individuals at greatest risk of TB disease.

Members can watch the seminar on LSHTM's Panopto Account
