Buruli ulcer is a neglected tropical skin disease caused by a bacterial infection and widespread across west and central Africa. Prompt diagnosis and correct antibiotic treatment is essential to prevent the serious disability and suffering that can arise with this disease. This project will develop a simple-to-use, rapid and low-cost diagnostic test for Buruli ulcer. This test can be used by health teams working in disadvantaged rural communities across Africa to provide prompt and correct treatment to reduce the suffering caused by this disease.

Rewiring Metabolism to Restore Stress Adaptation in Darier Disease

Grantee: Kathleen Green, Professor, Northwestern University, USA

Amount: DKK 3,762,928

Grant category: Research Grants

Year: 2025

Geography: USA

Darier Disease (DD) is an incurable skin disease caused by pathogenic variants in one copy of a calcium pump called SERCA2, sometimes accompanied by neuropsychiatric symptoms and seizures. The disorder typically appears in teenagers and comes and goes in response to various forms of stress, resulting in painful lesions due to loss of epidermal tissue integrity, vulnerability to infection, and loss of self-esteem. Even though the underlying genetic basis of DD was discovered >25 years ago, treatments are still limited to non-specific drugs with distressing side effects, antibiotics, and behavior modification. We identified a unique vulnerability of DD cells caused by their failure to turn on a metabolic pathway that protects normal cells against stress. We aim to revive this protective pathway to restore normal metabolism in DD cells, and in so doing, enhance tissue integrity and the ability to repair DNA and prevent damage to the remaining good calcium pump.

Decoding the evolution of anti-fungal immunity in the human skin

Grantee: Christina Zielinski, Professor, University of Cambridge, UK

Geography: United Kingdom

Fungal skin infections affect up to a quarter of people worldwide. They can also recur, spread and become life-threatening, especially in immunocompromised patients. This shows that our immune system does not always develop lasting and efficient protection. In particular, we don’t know why protective immune memory works so well against viruses but fails against fungi. Our project will study how special immune cells called T cells respond to fungal infections in the skin. By following patients with fungal skin infections over time, and comparing skin and blood samples, we will track how these immune cells are generated, maintained, or lost and what molecular weapons they use to fight the infection. We will use state-of-the-art and unique methodologies from our laboratory, allowing in-depth analysis of millions of T cells simultaneously at single-cell resolution. These insights could reveal new ways to strengthen our natural defenses and lay the foundation for future therapies.

Dissecting the role of the ageing tissue microenvironment in inflammatory immune responses within human skin

Grantee: John Connelly, Professor, Queen Mary University of London, UK

Amount: DKK 3,501,669

Grant category: Research Grants

Year: 2025

Geography: United Kingdom

The normal healthy functions of our skin significantly decline with age, and these changes increase the risk of infection, chronic wounds, inflammatory diseases, and cancer. Therefore, understanding the biological mechanisms underlying skin ageing is essential to protect against age-related diseases and maintain healthy skin function. The aim of this project is to dissect the cellular, biochemical, and mechanical processes of skin ageing and to directly test how they impact key functions, including tissue homeostasis and immunity. We will take advantage of state-of-the-art imaging and genomic methods available within our institution to profile the ageing process, and advanced 3D culture models of human skin will be used to test key genes and biochemical pathways. The results will provide fundamental insights into human skin ageing, and over the long term, they have the potential to identify key therapeutic targets for counteracting or preventing age-related skin diseases.

Breaking the Cytokine Dogma: Integrin Signals from Langerhans Cells Drive Antibody Immunity in Skin

Grantee: Botond Igyártó, Associate Professor, Thomas Jefferson University, USA

Geography: USA

Most vaccines and textbook models assume that special immune messengers called cytokines (such as IL‑6 or interferon‑α) are needed to tell T cells what to become. These cytokines are normally triggered by adjuvants in vaccines or by the immune system sensing pathogens. Our new findings overturn this view. We discovered that Langerhans cells—immune sentinels in the skin—can trigger strong antibody responses even in the steady state, when those cytokines are absent. Instead of relying on inflammatory messengers, they use surface “grip” proteins (integrins) to fine‑tune the conversation with T cells. This cytokine‑independent pathway may explain how the immune system quietly learns from the skin microbiome and maintains balance, while errors in this mechanism could underlie autoantibody diseases such as pemphigus or lupus. Our first goal is to confirm these findings. Once established, they will guide new strategies for vaccines or treatments that prevent chronic inflammatory skin disease.

A pigmented view of ciliopathies

Grantee: Michael Marks, Professor, The Children's Hospital of Philadelphia, USA

Amount: DKK 3,989,364

Grant category: Research Grants

Year: 2025

Geography: USA

Human skin pigmentation is highly variable among world populations and determines skin sensitivity to ultraviolet radiation, susceptibility to skin cancer, vitamin D production, and other outcomes. Much of this variability is determined by genetics. Using genetic analyses among diverse native Africans, we and our collaborators linked skin pigment variation with levels of expression of a gene called TMEM138. Inactivating mutations in TMEM138 or about 200 other genes cause developmental disorders called ciliopathies in which the primary cilium – a cell structure not known to impact pigmentation – fails to form properly. This proposal seeks to use cultured skin pigment cells called melanocytes and reconstituted human skin to better understand the molecular mechanisms by which TMEM138 specifically, and the primary cilium more generally, regulates pigment formation. Our study will provide new insights into skin pigment physiology and diseases and into how ciliopathy classes differ.

Establishing the First Human Skin Organoid Platform to Redefine Therapies for CYLD Cutaneous Syndrome

Grantee: Abbas Shafiee, Senior Research Fellow, The University of Queensland, Australia

Amount: DKK 3,991,497

Grant category: Research Grants

Year: 2025

Geography: Australia

Skin diseases affect millions worldwide, yet research and treatment often rely on animal models that do not fully capture human biology. In this project, we will use patient-derived stem cells to grow miniature 3D models of human skin, called organoids. These living models mimic how skin develops, functions, and responds to disease, allowing us to study rare genetic conditions directly in the lab. By comparing patient organoids with genetically corrected “healthy” controls, we will uncover the biological mistakes that cause disease and identify new treatment targets. We will also test whether these organoids can predict how patients respond to therapies, offering a path toward safer and more effective medicines. This research aims to set a new standard for dermatology by reducing reliance on animal experiments, accelerating drug discovery, and improving care for people living with severe skin disorders.

Decoding microbial-immune crosstalk to modulate immune checkpoint inhibitor-induced skin toxicity

Immunotherapy has transformed cancer treatment, helping the body’s immune system attack tumors. Unfortunately, these powerful drugs often cause side effects when the immune system also attacks healthy tissues. The skin is one of the most commonly affected organs, leading to rashes and other painful conditions that can force patients to stop life-saving therapy. Our project aims to understand why this happens. We recently discovered that certain immune cells, called CD8 T cells, are activated by bacteria living on the skin and then attack healthy skin cells during treatment. We will study how these bacteria and immune cells interact and test new ways to prevent this process. By uncovering how microbes trigger skin damage, our research could pave the way for safer cancer immunotherapies, helping patients stay on treatment longer while avoiding harmful side effects.

Mitochondrial transfer in wound healing

Grantee: Sabine Werner, Professor, ETH Zürich, Switzerland

Amount: DKK 3,560,550

Grant category: Research Grants

Year: 2025

Geography: Switzerland

Chronic wounds or hypertrophic scars affect a large percentage of the population world-wide, but the therapeutic options are still limited. The development of innovative wound therapeutics requires a thorough understanding of the mechanisms underlying normal and impaired healing. This project will study a new regulatory mechanism in wound healing – the transfer of metabolically highly active cell organelles (mitochondria) between different cell types and the functional consequences for wound healing. We will use state-of-the art cell culture and mouse models to determine if mitochondrial transfer has beneficial effects on recipient cells and if this promotes the wound healing process. Through collaboration with clinical partners, we will determine the importance of our findings for normal and impaired healing in humans. The results will pave the way for the development of new wound therapeutics that target mitochondrial transfer or proteins regulated by this process.

Project: Leveraging Real-World Data for Dermato-Epidemiological Research of Bullous Pemphigoid and Lichen Planus in Denmark

Bullous pemphigoid and lichen planus are inflammatory diseases of the skin and mucosa causing significant discomfort and reduced quality of life. Still, their causes, treatments, and long-term effects are poorly understood. The project will use Denmark’s unique health registries to explore how common these diseases are, what triggers them, how they are managed, and their broader health impact. Findings will support data-driven healthcare, ensuring better resource allocation and equitable access to specialized care. Improved understanding of the diseases and their complications will also highlight gaps in care, improve disease awareness, and empower shared decision-making for patients and doctors. The project will be conducted within ARISE (the Aarhus University Research group for Investigating Skin disease Epidemiology), a new research initiative aimed at establishing a lasting foundation for this novel type of skin disease research and better patient care.
