NONEGON
PROJECT

5th Joint Call: NONEGON

The proposal aims to identify novel inhibitors of the enzyme 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR) in Neisseria gonorrhoeae as a strategy to combat multidrug-resistant gonorrhea. By applying high-throughput screening, drug repurposing, and computational modeling, NONEGON seeks to deliver new antimicrobial leads that can progress toward clinical development.
Posted on

Background

Neisseria gonorrhoeae causes gonorrhea, the second most common sexually transmitted infection worldwide, with approximately 87 million new cases annually. The pathogen is listed as a high-priority organism by the WHO due to rapidly rising antimicrobial resistance, including strains resistant to ceftriaxone and azithromycin.

The DXR enzyme, essential in the methylerythritol phosphate (MEP) pathway for isoprenoid biosynthesis, is absent in humans but critical for bacterial survival. This makes it an ideal drug target. Previous studies have shown DXR inhibitors are effective in E. coli, Y. pestis, M. tuberculosis, and apicomplexan parasites. NONEGON aims to apply this concept to N. gonorrhoeae.

The project

NONEGON pursues the following objectives:

  • High-throughput screening of up to 100,000 synthetic compounds for DXR inhibition.
  • Drug repurposing screen of 6,500 approved drugs to identify candidates with immediate translational potential.
  • Natural product library screen including thousands of pure compounds and herbal extracts.
  • Structure-based virtual screening of millions of commercially available compounds.

MicroLung
PROJECT

5th Joint Call: MicroLung

The proposal aims to develop a pulmonary blood-air barrier model to study COVID-19 pathogenesis and screen potential therapeutics. By combining tissue engineering and microfluidic systems, the project seeks to replicate the complex lung microenvironment, enabling more accurate studies of virus-host interactions and testing of nanoparticle-based therapeutic delivery.
Posted on

Background

The COVID-19 pandemic underscored the urgent need for advanced models of infectious respiratory diseases. Current cell culture systems fail to mimic the complexity of the human lung, while animal models lack essential properties of the human pulmonary blood-air barrier, often requiring costly humanized transgenic systems.

To advance understanding, there is a need for experimental platforms that reproduce the pulmonary microphysiology, particularly the alveolar epithelial cells targeted by SARS-CoV-2. Such models can reveal mechanisms of viral entry and progression, while supporting the evaluation of novel therapeutic interventions.

The project

MicroLung pursues the following objectives:

  • Develop pulmonary blood-air barrier models using microfluidic and tissue-engineered systems.
  • Design nanoparticles functionalized with ACE2-specific peptides to mimic viral binding and compete with SARS-CoV-2 for cell entry.
  • Engineer nanoparticles carrying antiviral agents for drug transport studies across the lung barrier.
  • Validate models with SARS-CoV-2 isolates in biosafety level 3 laboratories to compare nanoparticle results with actual viral behavior.
  • Foster transnational collaboration between partners for nanoparticle design, microfluidic systems, and virus validation studies.

TimCovSEAEu
PROJECT

5th Joint Call: TimCovSEAEu

The proposal aims to characterize T-cell immunity to SARS-CoV-2 across Southeast Asian and European populations. By identifying T-cell epitopes recognized in diverse HLA contexts, the project seeks to advance understanding of immune responses, support vaccine development, and provide tools for long-term monitoring of protective T-cell immunity against COVID-19 and future coronavirus outbreaks.
Posted on

Background

The COVID-19 pandemic and earlier coronavirus outbreaks (SARS, MERS) demonstrate the ongoing threat of zoonotic spillovers. Vaccines inducing both antibody and T-cell responses against conserved viral regions are essential. However, T-cell epitopes vary across populations due to differences in HLA allele prevalence.

Most studies so far have focused on Caucasian populations, neglecting alleles like HLA-A*24:07, common in Southeast Asia. This project brings together partners from Indonesia, Thailand, and Germany to identify SARS-CoV-2-specific epitopes relevant to these populations, filling a major research gap.

The project

TimCovSEAEu pursues the following objectives:

  • Identification of T-cell epitopes: Use immunoinformatics algorithms (SYFPEITHI, NetMHCpan) to predict SARS-CoV-2 CD4+ and CD8+ epitopes for the most frequent HLA class I (15 alleles) and HLA-DR (6 alleles) in Southeast Asia.
  • Experimental validation: Conduct high-throughput ELISpot assays using PBMCs from COVID-19 convalescent donors to confirm T-cell responses.
  • Immunological characterization: Compare T-cell responses in COVID-19 convalescents versus uninfected individuals to assess immunity and memory.
  • Application for vaccines and immunotherapies: Provide candidate epitopes for multi-peptide vaccines and adoptive T-cell therapies.

The science

The consortium integrates computational prediction with experimental validation:

  • Immunoinformatics analysis of the SARS-CoV-2 proteome.
  • High-throughput epitope screening using ELISpot assays.
  • Comparative immunology across Indonesian, Thai, and European cohorts.
  • Clinical translation through collaboration with hospitals and immunotherapy centers.

Expected outcomes include novel epitope panels for monitoring T-cell memory, deeper insights into cross-population immunity, and candidate structures for next-generation vaccines and therapies.

Background

The current antibiotic crisis represents a global problem of fundamental importance, comparable with other global challenges as e.g. climate change or sustainable energetics, but far less discussed in the society. Without active approach right now the, the infectious diseases will soon become the most frequent cause of death worldwide.

The TIC-TAC project consists of two objectives aiming to avert the threat of an antibiotic crisis: 1) Knowledge-based hunt for novel bioactive metabolites derived from plants and microorganisms and 2) Development of promising compounds into drugs.

 

The project

Within the Objective 1 we will create a collection of 1000+ unique Actinobacteria strains, a corresponding number of culture broth crude extracts, and 100+ plant crude extracts. Metabolites in the crude extracts will be separated into 5000+ fractions and these will be tested for a broad spectrum of biological activities, particularly against clinically important pathogenic microorganisms (including MDR strains). These include Mycobacterium tuberculosis (causing tuberculosis), G- bacteria, Plasmodium falciparum (causing malaria), Zika virus, and others.

The Objective 2 aims to the development of previously patented hybrid lincosamide derivatives developed by the Czech team and further compounds suggested by SEA teams into drugs.

The science

Our strategy to combat the antibiotic (antibacterial and antiparasitic) crisis exploits natural products that proved to be a superior source of druggable compounds. We will use modern biology and chemistry methodology for this purpose – knowledge-based genome mining (oriented on the search for biosynthetic pathways utilizing alkyl-proline derivatives, which are far more efficient when compared to L-proline incorporating compounds), mass spectrometry-based metabolomics (GNPS molecular networking + other bioinformatics tools); and we will focus on testing multiple targets, i.e. multiple pathogens including those clinically most important and threatening. CZ team will provide a collection of the clinically most dangerous bacterial strains from the WHO list for antimicrobial activity testing; Thai team possess a collection of P. falciparum strains for antimalarial properties and resistant M. tuberculosis strains for antimicrobial properties testing. Unique sources of bioactive metabolites from yet underexplored Thai and Indonesian biotopes will be used to search for new compounds.

tuber
PROJECT

4th Joint Call: SMART-TB

Tuberculosis (TB) remains an urgent public health threat and a leading infectious cause of death worldwide. The SMART TB project propose a novel app that will not only screen patients who are being non-adherent, but will also guide healthcare providers to identify patients’ individual problem and to deliver the recommended personalized strategies
Posted on

Background

Tuberculosis (TB) remains an urgent public health threat and a leading infectious cause of death worldwide. Despite long-term support such as directly observed treatment to help patients complete their treatment, non-adherence to TB treatment is known to be suboptimal which leads to treatment failures, poor quality of life, or development of multidrug-resistant tuberculosis. The reasons underlying non-adherence are not entirely independent and are heterogeneous. Digital interventions are gradually being integrated into practice because of affordable mobile electronic devices in many settings. However, the flaws of some of the existing digital technologies to improve medication adherence are that they are not tailored to patients’ individual problems. The existing apps are commonly delivered as a one-size-fit-all intervention, assuming that the reasons for non-adherence are the same for the patients. We propose a novel app that will not only screen patients who are being non-adherent, but will also guide healthcare providers to identify patients’ individual problem and to deliver the recommended personalized strategies

 

The Project

The aim of this project is to develop a smart-phone application for health care providers that can be used for personalized interventions to improve medication adherence of TB patients (SMART-TB) in Indonesia. The proposed apps can be applied in primary, secondary and tertiary health facilities in Indonesia and can be adapted to other high-TB prevalence countries.

 

The Science

The SMART-TB app will be developed in Bahasa with five main functions, called SIM-CAR functions, as follow: Screening (to identify medication adherence problems in TB patients), Intervening (to intervene in TB patients’ individual problems of medication adherence), Monitoring (to monitor TB patients in taking their medication), Communicating (to communicate about medication adherence among TB officers (pharmacist/ TB programmer), TB patients, and TB experts), and Administrating (to register patient information related to medication adherence until the TB treatment outcomes are measured). In the first year, we will develop a prototype of the SMART-TB. Its content development will be performed through a literature review and qualitative study. In the second year, pilot testing will be conducted to validate the content and implementation of the prototype in a small-scale population representing rural and urban area. In the third year, the content and system of the SMART-TB will be validated based on the results of the pilot testing.

DAADTHEMAC
PROJECT

4th Joint Call: DAADTHEMAC

Neural angiostrongyliasis, the cause of eosinophilic meningitis, is a consequence of the migration of larvae of the nematode parasite (rat lungworm) Angiostrongylus cantonensis in humans and animals. Resulting disease, termed also Angiostrongylus Eosinophilic Meningitis (AEM) is considered a prominent Emerging Infectious Disease.
Posted on

Background

Angiostrongylus cantonensis is a unique pathogen that is predominantly dependent on invasive rodent and mollusc hosts. Continuing spread of these organisms has led to wide distribution of AEM throughout the tropics. The majority of clinical cases are reported from SE Asia (the highest incidence in Thailand), however, the disease is broadly distributed in Pacific regions (French Polynesia, Hawaii, Australia) with recent invasions into continental USA. Recently, the pathogen was discovered in rats in the Canary Islands and two year ago, clinical human AEM cases were reported in France. Most recently, in 2019, the parasite was detected in Mallorca, Spain, demonstrating immediate risk of spread in southern parts of EU territories.

 

The Project

This project aims to develop a novel diagnostic tool for human eosinophilic meningitis caused by Angiostrongylus cantonensis, namely a LAMP assay for AC detection in clinical cases, in various organism that serve as infection sources and in environmental samples. Our project consortium combines teams with expertise in various fields of human and veterinary medicine, ecology and infection biology. Project benefits from experience of EU and Thailand teams with development of molecular-based diagnostic tools including the LAMP technology, equipment and experimental work with AC, combined with partnerships/collaboration with research teams from countries with high incidences of AEM clinical cases in SE Asia (Philippines, Thailand, Indonesia). With synergic involvement of adjunct research partners from Australia, Spain, Italy and UK, the project team aims at (i) technological progress in AEM clinical diagnostics, (ii) detection of AC in food chains and (iii) understanding of local as well as global epidemiology of this emerging disease.

 

The Science

As the epidemiology of AEM involves humans, various mammals and birds, invertebrates, as well as environmental components, the One Health approach represents an ultimate avenue in diagnostics and prevention of this emerging disease.  As a result, composition of the consortium, the project involves experimental activities associated with development, optimization and experimental testing of developed assays, alongside clinical evaluation in medical facilities in SEA and detection of AC in the food chain and environment. Proposed LAMP diagnostics offer a range of advantages over other diagnostic approaches as it is applicable in field and clinical conditions as does not require time consuming and technologically demanding steps. The results of this project can be immediately disseminated and translated into sensitization of local populations and public awareness, respecting given cultural context and stage of development of partnering ASEAN countries.

PROJECT

2nd Joint Call: NEWTONIAN

The Asian liver fluke Opisthorchis viverrini is intensively transmitted in Southeast Asia (SEA), particularly Lao PDR, Thailand and Cambodia. The helminth adult worm lives in human bile ducts of the liver where it causes a multitude of severe pathologies including cholangiocarcinoma (CCA), a fatal bile duct cancer.

Background

The Asian liver fluke Opisthorchis viverrini is intensively transmitted in Southeast Asia (SEA), particularly Lao PDR, Thailand and Cambodia. The helminth adult worm lives in human bile ducts of the liver where it causes a multitude of severe pathologies including cholangiocarcinoma (CCA), a fatal bile duct cancer. While in Northeast Thailand research on control tools and public health interventions have much advanced over the past decades, progress made in research and disease control is limited in Lao PDR and Cambodia and the interventions are rather temporary and focal.

There are major challenges for the successful control of O. viverrini infection and related morbidity. Firstly, the currently widely available diagnostic techniques (e.g. Kato-Katz) have a low sensitivity. Secondly, the extent of morbidity (disease) associated with the O. viverrini infection is unknown in many O. viverrini endemic settings. Thirdly, given the lack of adequate regional estimations of O. viverrini infection and the related mortality and morbidity, the currently employed level of control initiatives cannot be adequate planned.

 

The Project

Our project consortium, consisting of four institutions in Switzerland, Thailand, Lao PDR and Cambodia, each having several decades of experience in Asian liver fluke research and control, aims to develop new tools to control of O. viverrini infection and associated morbidity and mortality in SEA region. Our objectives are (i) to regionally validate a promising rapid diagnostic tests for O. viverrini infection in field sites in Cambodia, Lao PDR and Thailand; (ii) to compile existing data on O. viverrini infection and associated mortality and morbidity in Cambodia, Lao PDR and Thailand and complement them with additional survey data in areas where only sparse information is available; and (iii) to predict the risk of O. viverrini infection and related mortality and morbidity across Southeast Asia.

 

The Science

This transnational project will lead into a SEA regional view of O. viverrini infection and related morbidity and mortality. For objective (i), a field validation of the urine based detection of circulating O. viverrini will be performed. Two promising tests will be validated: A urine- and a corpro-antigen based diagnostic test, which have a documented high potential for further development. The validation will take into account the different levels of endemicity of O. viverrini infection, and the helminthic co-infections. It will be performed in settings in Lao PDR, Thailand and Cambodia. For objective (ii) an database will be created where existing geo-localized data on O. viverrini infection and associated morbidity will be combined with newly surveyed data. A systematic review of published literature on O. viverrini infection, and related morbidity and mortality will be conducted to achieve a most comprehensive database. For objective (iii), the database will be used for the prediction of O. viverrini infection, morbidity and mortality in area where no data is available and across all three endemic countries by using a well-established Bayesian geo-statistical modelling approach.

PROJECT

2nd Joint Call: PNEUMOFLUIDICS

The serological diagnosis of pneumococcal disease on the basis of a single antigen is a challenge, because natural antibodies caused by previous colonization events and the antigenic variability of pneumococci are impaired. A combination of validated immunogenic antigens high-throughput diagnostics is needed to differentiate diseased and healthy people
Posted on

Background

Streptococcus pneumoniae, also known as the pneumococcus, is a Gram-positive pathogen recognized as a major cause of pneumonia worldwide. It resides as a commensal in the nasopharynx of healthy carriers, but in susceptible individuals this bacterium can spread to other body locations and cause life-threatening disease. The main group risks are the elderly, immunocompromised people and infants. In fact, approximately 900,000 children die each year due to pneumococcal disease, of which >90% occur in developing countries. In addition, a high number of pneumococcal infection cases are diagnosed in developed countries and can be associated with high morbidity in children and are an important factor that influences quality of life and produces significant mortality in adults. There are licensed polysaccharide-based vaccines to prevent pneumococcal infections, but their efficacy is limited. Therefore, pneumococcal community-acquired pneumonia (CAP) remains as an important health problem and once it has occurred, early diagnosis with accurate diagnostic methods is essential in order to provide patients with prompt and appropriate therapy. The ability to identify pneumococci as a causative agent in lung infections is quite limited and blood cultures are often negative. Serological diagnosis of pneumococcal disease based on a single antigen is often challenging, due to the interference of natural antibodies elicited by previous colonization events and the antigenic variability. Therefore, to better discriminate between diseased and healthy people, a combination of antigens would be desirable.

 

The Project

The aim of PNEUMOFLUIDICS is to develop an innovative point-of-care diagnostic for the early detection of Streptococcus pneumoniae (pneumococcus) infections on a serological basis. Results of multiplex analyses will be transferred to a microfluidic protein array (MPA), i.e. a biosensor on which proteins are immobilized and on which a novel serodiagnostic method can be established with minimal serum samples.

 

The Science

Research aims to develop a sensitive and quantitative tests for the rapid and specific detection of pneumococcal infections. For the validation of a microfluidic protein array (MPA), the detection of IgM antibodies as well as specific IgG antibodies will be performed in larger patient cohorts using initially well-established multiplex platforms for pneumococcal antigens. Selected pneumococcal antigens can also be used for immunostrips that will be probed with independent sets of patient sera. These immunostrips are a diagnostic test can be an easy-to-use tool for diagnosis in healthcare systems, especially in low-resource areas. The pneumococcal-specific MPA will be further used for a broad range of applications such as monitoring epidemiological episodes or discovering new protein vaccine candidates. This strategy will help to distinguish between patients with different diseases. The multiplex platforms or MPA can be employed in epidemiological surveillance programs to monitor possible outbreaks of pneumococcal disease around the world.
