In August 2025, researchers from the Department of Cancer Research published a study in the journal Proceedings of the National Academy of Sciences (PNAS) that uncovers a novel mechanism cancer cells use to escape detection by the immune system.
The team, from the Cytoskeleton and Cancer Progression group led by Clement Thomas, found that tumour cells can rapidly reposition inhibitory molecules to the interface where they contact Natural Killer (NK) cells, effectively dampening the immune attack. This reorganisation is driven by actin filaments within the cancer cell, allowing these inhibitory signals to accumulate precisely at the immunological synapse just minutes after contact. Blocking this actin‑mediated transport restored NK cell activity in preclinical models, enabling immune cells to kill cancer cells more effectively.
This discovery sheds light on the dynamic strategies tumours use to avoid immune destruction and highlights potential targets for therapies aimed at enhancing immune‑mediated cancer clearance.

Researchers from the Tumor Stroma Interactions group at the LIH, working with the German Cancer Research Center, identified a potential new target for immunotherapy in Chronic Lymphocytic Leukaemia (CLL), the most common adult blood cancer in Europe, which remains incurable despite treatment advances.
Their study, published in August 2025 in Nature Communications, shows that the protein galectin‑9 suppresses the function of T cells, which are crucial for the body’s immune response to cancer. Galectin‑9 is released in large quantities by leukaemic cells and interacts with the TIM‑3 receptor on T cells, acting as a brake on immune activity.
In preclinical models, blocking galectin‑9 revived exhausted T cells and slowed tumour growth, suggesting a novel therapeutic approach. Because galectin‑9 is also overexpressed in other tumour types, this strategy could have broad applications. The research also highlights additional molecular targets for future investigation.

Researchers from the Tumor Immunotherapy and Microenvironment (TIME) group at the LIH are collaborating with Cytovation ASA, a Norwegian biotech company developing CY-101, an innovative cancer immunotherapy. Within this collaboration, the TIME group contributes to research efforts supporting the understanding of CY-101’s biological activity. The collaboration takes place within the Eurostars project, co-funded by the European Partnership on Innovative SMEs (Eurostars) program and the Luxembourg National Research Fund (FNR).
CY-101 has shown promising results in preclinical studies as well as in a Phase 1/2a clinical trial conducted by Cytovation and its clinical partners in patients with advanced solid tumors, including adrenocortical carcinoma (ACC). Based on these findings, Cytovation obtained Orphan Drug Designation (ODD) from the U.S. Food and Drug Administration (FDA) for CY-101 for the treatment of ACC, a rare and aggressive endocrine cancer with limited therapeutic options and has secured a clinical research collaboration with Cancer Research UK, one of the world’s leading funders of cancer research.
“The FDA Orphan Drug Designation and the collaboration with Cancer Research UK represent important milestones in the development of this unique therapeutic approach for patients with limited treatment options. We are pleased to continue collaborating with Cytovation and to contribute to research efforts aimed at improving the understanding of CY-101’s mechanism of action and supporting its ongoing development”

In September 2025, the LIH secured a prestigious European Research Council (ERC) Starting Grant to fund a new five year research initiative called IMMUNAGENOMICS. This project, led by Dr Ángel Álvarez Prado, Principal Investigator at the Translational Cancer Immunogenomics group, will study how ageing and genetic variation shape the immune environment of metastatic brain tumours, with the aim of developing personalized therapies and improving outcomes for patients.
Brain metastases affect up to 40% of cancer patients and are associated with poor prognoses, despite recent advances in treatment. By integrating advanced genomics, immunology and cancer biology techniques such as single cell RNA sequencing and spatial transcriptomics, the team hopes to gain a detailed understanding of tumour immune interactions across different age and genetic backgrounds. The grant highlights the role of the LIH as a European leader in cancer immunology research.

In December 2025, The Lancet published the VENUSCANCER study, which provides a global picture of care for women diagnosed with breast, cervical and ovarian cancers.
The research, in which the EPICAN group of the LIH led by Dr Claudine Backes participated, analysed high resolution data from over 250,000 women across 39 countries, diagnosed between 2015 and 2018, including also data from the Luxembourg National Cancer Registry. It examined cancer stage at diagnosis, staging procedures, treatments received and biomarkers to understand global variations in care and outcomes.
Findings revealed notable inequalities: women in low and middle income countries are far less likely to be diagnosed early and to receive guideline consistent treatment than those in high income countries, with substantial differences also associated with age and healthcare access. The study underscores the need for tailored clinical guidelines and early detection efforts to reduce disparities worldwide.

In January 2025, the Directorate of Health and the EPICAN Cancer Epidemiology and Prevention Group at the LIH jointly published the first evaluation of Luxembourg’s national organised breast cancer screening, the Mammography Programme (PM). For the assessment a new method was developed, linking data from the National Cancer Registry with PM records to measure screening effectiveness.
The study shows that cancers detected through the PM are generally identified at earlier stages, are smaller and less likely to have spread to lymph nodes compared with those found outside the programme, underlining the benefit of early detection for treatment outcomes and prognosis. The double reading of mammograms by two independent radiologists improves cancer detection and reduces false positives, cutting additional tests and emotional stress.

In May 2025, the NORLUX Neuro-Oncology team played a key role in an international collaboration that resulted in two publications in Nature Genetics. These studies, conducted by the CARE consortium, uncover how glioblastoma tumour cell states co-evolve with their surrounding tumour microenvironment, giving rise to heterogeneous and complex cellular niches.
By analysing matched primary and recurrent tumours at the single-cell level, the team demonstrated that the molecular evolution of tumour cells upon recurrence is closely linked to histopathological changes and the dynamic composition of microenvironmental niches.
This breakthrough was made possible through extensive international collaboration and access to unique patient cohorts, including LIH’s PRECISION-PDX study.

In January 2025, the LIH published preliminary findings from the national Colive Cancer survey, part of the Plan National Cancer (PNC2), which focuses on the experiences of 100 women living with or after breast cancer. The survey participants, with an average age of 50, mostly reside in Luxembourg and reported positively on their care experience overall, with an average score of 8 out of 10 for the communication of diagnosis and support received.
Around 80% of respondents felt satisfied with the information provided by their healthcare teams, and a substantial majority were offered psychological support and holistic care resources such as physiotherapy and sports programmes.
A key area for improvement identified in the survey was the need for more detailed information about treatment side effects, highlighting potential gaps in patient education.

In May 2025, scientists from the LIH significantly contributed to a major international study published in Cell that reveals how immune cells navigate through the body using complex chemical signals. The research deciphers how chemokines and their receptors, known as GPCRs, function as encrypted navigation cues that direct immune cell movement, with wide ranging implications for cancer therapy, infection response and precision medicine.
Researchers from the Immuno Pharmacology and Interactomics group, led by Dr Andy Chevigné and Dr Martyna Szpakowska, played a central role in experimentally validating how tiny, disordered protein regions act as “digital encryption keys” that determine specific cell responses. Their work was supported by the in house NanoLux platform, enabling precise investigation of ligand-receptor interactions and signaling.
The findings pave the way for engineering immune cells that can be guided to precise targets such as tumours or infection sites, and for designing therapeutic proteins that modulate immune responses with high specificity.
“It’s incredibly exciting to see how these short, unstructured and often overlooked protein segments actually hold the key to highly selective cell communication”, Dr Andy Chevigné, Co-leader of the Immuno-Pharmacology and Interactomics group
The study also underscores the importance of patient-derived models in replicating the complexity of GBM and improving the understanding of treatment responses. Notably, researchers discovered that microglia, the brain’s resident immune cells, undergo significant transformations when interacting with GBM, mimicking both phagocytic and dendritic cells. Additionally, chemotherapy was found to alter the molecular landscape of both the tumour and its surrounding immune environment, reinforcing the need for therapies that consider these intricate interactions. This collaborative effort, involving the LIH and partners across Luxembourg and Europe, marks a significant step forward in cancer research, with the potential to inform new immunotherapeutic strategies for patients battling GBM.

In September 2025, researchers from the Infection and Immunotherapy Research group at the LIH published a study in eBioMedicine on innovative approaches to fight multidrug resistant bacteria by harnessing the innate immune system.
The team focused on Pseudomonas aeruginosa, a pathogen increasingly resistant to antibiotics and responsible for severe infections in hospitalised and immuno compromised patients. They developed novel complement activating multimeric immunotherapeutic complexes (CoMiX) that target the bacterium by stimulating the complement system, a key arm of innate immunity.
In a preclinical pneumonia model, intranasal administration of CoMiX reduced bacterial load and enhanced immune response by increasing complement activation and recruiting neutrophils to the lungs. This proof of concept suggests that directed activation of innate immune pathways could offer a rapid and promising therapeutic avenue against multidrug resistant pathogens and potentially other infectious agents. Future studies will focus on long-term efficacy and any potential off target effects.

Researchers from the LIH Neuro-Immunology group and the University of Luxembourg published a review article in May 2025 in the Journal of Neuroinflammation exploring how the brain’s immune cells, known as microglia, contribute to the earliest stages of Parkinson’s disease, long before typical motor symptoms appear.
The article investigates how microglial activation and immune dysfunction may drive disease progression. It emphasises emerging evidence that immune interactions in the brain’s innate defence system are integral to the onset and advancement of Parkinson’s disease.
The review also discusses advances in neuroimaging, experimental models and biomarker research that are improving scientists’ ability to track microglial activity and immune changes. Such tools could be crucial in identifying individuals at risk and developing early, personalised interventions that may slow or alter disease progression.

In May 2025, a Spotlight article by Prof. Dirk Brenner, head of the Experimental & Molecular Immunology group at the LIH, and Andrea Riviello, a graduate student in the Translational & Clinical Immunology group, was published in Cell Metabolism. The piece highlights a study that explores how macrophages process bacteria.
The research demonstrates that bacterial components are not simply degraded for disposal but are recycled to support macrophage metabolism and biosynthesis. This discovery uncovers a novel connection between innate immune defence and cellular metabolic programming, emphasising how immune cells can repurpose nutrients to sustain their function.
In their article, Brenner and Riviello discuss the broader implications for immunometabolism, host-pathogen interactions, and potential therapeutic strategies aimed at modulating immune cell activity.

In August 2025, scientists from the Department of Infection & Immunity published a comprehensive review in Mucosal Immunology that shines a light on the largely uncharted world of gut microbes living in the mucus layer of the colon. The article, Living on the edge: Mucus associated microbes in the colon, was authored by Mihovil Joja, Erica Grant and Prof. Mahesh Desai of the Nutrition, Microbiome & Immunity group.
The review explores how these mucus dwelling bacteria interact with the gut barrier and influence health and disease, including the delicate balance between protective and harmful microbial activity. It highlights advanced tools like spatial imaging, microdissection and multi omics for studying these organisms, and discusses how diet, antibiotics and immune factors shape this complex ecosystem.
Importantly, the authors categorise mucus layer microbes into different nutrient strategies and note that standard stool based analyses often miss them, underscoring the need for better sampling and translational research to harness microbiome based therapies.

In July 2025, a global panel of scientists published new consensus guidelines aimed at improving research and therapeutic development related to the gut microbiome. The report, co authored by Prof. Mahesh Desai from the Nutrition, Microbiome & Immunity group, appeared in Nature Reviews Gastroenterology & Hepatology and reflects an EU supported collaborative effort.
The guidelines emphasise that, given the complexity of the gut microbiome and its links to conditions such as inflammatory bowel disease, obesity, type 2 diabetes and liver disease, no single preclinical model is sufficient on its own. Instead, researchers should integrate complementary systems like germ free animals, organoids and organ on a chip to strengthen causal insights and clinical relevance.
Dietary approaches and pre /postbiotics were identified as promising therapeutic strategies, while support for probiotics and faecal transplants was mixed. The guidelines call for greater standardisation, multi omics integration and development of models that more accurately reflect human biology.

In October 2025, an editorial by Dr Annette Kuehn, Co Head of the Molecular & Translational Allergology group, and collaborators from Austria, was published in the journal Allergy, the leading journal in the field of allergy research. The article argues that the gastrointestinal immune system is an underappreciated factor in the success of oral immunotherapy (OIT) for peanut allergies.
While OIT is one of the most promising approaches to desensitise individuals with food allergies, the authors note that outcomes vary widely between patients. They propose that differences in the gut immune environment, including mucosal barrier integrity, networks of immune cells and the gut microbiome, may explain variability in treatment response. Integrating gut immune parameters into clinical research, they suggest, could lead to a deeper understanding of immune tolerance and improve the effectiveness and safety of OIT and other food allergy therapies.

In September 2025, a new position paper published by the European Academy of Allergy and Clinical Immunology (EAACI), with participation from Dr Christiane Hilger, Co Head of the Molecular & Translational Allergology group at the LIH, outlined how high dimensional “omics” technologies are reshaping allergy diagnosis and treatment.
The review highlights that combining data from genomics, proteomics, transcriptomics, metabolomics and cytomics with clinical information can refine disease classification and identify biomarkers that support personalised care for conditions such as asthma, atopic dermatitis, allergic rhinitis, food allergies and drug hypersensitivity. This molecular insight is helping to recognise distinct subtypes of allergic diseases rather than treating them as uniform disorders, potentially enabling more targeted therapies.
Despite the promise of omics approaches, challenges remain in their translation into routine clinical practice, including issues of cost, data complexity, sample standardisation and regulatory hurdles. The paper calls for collaborative efforts and harmonised protocols to overcome these barriers and realise the potential of precision allergy medicine in daily patient care.

In February 2025, the Registries & Epidemiological Studies group (RES) led by Aline Lecomte, in collaboration with the Direction de la Santé, published results from the OECD PaRIS Survey, an international survey assessing public perceptions of national healthcare systems. In Luxembourg, 1,590 patients and 52 medical practices participated.
Overall satisfaction with care in Luxembourg was found to be very strong. Over 90% of respondents rated the quality of care positively and said healthcare services met their needs, above the OECD average. Participants also reported good health, with 72% indicating good physical health and 86% good mental health.
However, the survey also highlighted areas that need improvement. Patients reported challenges in managing their own health and pointed to limited coordination of care for chronic conditions. Improving health literacy and better integrating services could also strengthen support for people living with chronic diseases.

The research builds on earlier findings linking greater cushioning to lower injury rates and aims to guide future footwear design for injury prevention.
Shortly after, in April, the LIH Human Motion, Orthopaedics, Sports Medicine and Digital Methods Group led by Dr Bernd Grimm joined the SmILE project, a €20.7 million, five-year Horizon Europe initiative to transform musculoskeletal non-communicable disease (MSK-NCD) management. The consortium of 25 European partners will develop smart implants, wearable sensors, and an AI-driven digital platform to enable earlier diagnosis, personalised rehabilitation, and continuous monitoring. The goal is to improve patient outcomes, support clinical decision-making, and reduce the long-term burden of conditions such as osteoarthritis and fracture recovery.
Together, these initiatives highlight the strategic focus of the LIH on combining large-scale clinical research and digital health innovation to strengthen prevention and long-term musculoskeletal care.
