Patients with atopic dermatitis (AD) are much more likely to develop other environmental (pollen, dust mites) or food allergies, but we do not understand why. Our immune system usually ignores most proteins in contact with the skin, yet some people, have a strong reaction. With this project we aim to determine whether human and microbe enzymes on AD-affected skin can turn harmless proteins into allergens by cutting them or chemically modifying them. We will use lab-grown human skin models and cutting-edge tools to see how bacteria and damaged skin cells alter proteins like those from pollen, dust mites, of peanut and whether these changes make them more likely to trigger allergic reactions. We will also study how these modified proteins are recognised by the immune system. The results could lead to better ways to prevent allergies in people with AD, such as treatments that block harmful enzymes, protect the skin barrier, or train the immune system to tolerate allergens.

The Proteome of Chronic Urticaria

Grantee: Marianne Løvendorf, PI, Zealand University Hospital, Denmark

Amount: DKK 3,680,000

Grant category: Research Grants

Year: 2025

Geography: Denmark

Chronic urticaria, also known as chronic hives, is a common skin condition causing itchy rashes and swelling, considerably impacting the quality of life. Although common, the exact cause remains unknown. We will study the proteins involved in chronic urticaria to better understand the underlying disease mechanisms and hopefully find new treatment options. We will use a specialized technique called mass spectrometry to measure the proteins in skin samples from patients with hives and healthy controls. With this approach we can determine which proteins are altered in affected skin, offering new insights into the underlying causes of the condition. Additionally, we will study how immune cells and nerve signals affect the disease by conducting laboratory experiments. By understanding the biology of chronic urticaria better, we hope to contribute to the development of more effective and targeted treatments that could help people suffering from this challenging condition.

PepBoost – Proteasome-derived defence peptides as accelerators of wound healing

Grantee: Elizabeth Soares Fernandes, Associate professor, Aarhus University, Denmark

Amount: DKK 3,994,580

Grant category: Research Grants

Year: 2025

Geography: Denmark

Pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa are commonly associated with non-healing and aggravated wounds, since they can colonize and invade host tissues, and many times cause life threatening conditions such as sepsis. Resistance to the available antibiotic therapies has been reported for both bacteria, and serious S. aureus skin infections are noted in both humans and animals. This project will investigate the ability of proteasome-derived defence peptides (PDDPs) – which can be naturally produced by our body – to protect against infection whilst promoting wound healing. It will also analyse the mechanisms by which PDDPs exert their effects. For this, different techniques (in vitro, ex vivo and molecular biology) will be used. For the ex vivo experiments, a wound dressing containing PDDPs will be developed with specific characteristics to allow PDDPs to target the pathogens whilst promoting wound healing.

Novel treatment for accelerating wound healing with AI-driven, de novo designed proteins blocking Granzyme K

Grantee: Sine Hadrup, Professor, Head of Section, Technical University of Denmark, Denmark

Amount: DKK 3,982,500

Grant category: Research Grants

Year: 2025

Geography: Denmark

Chronic skin wounds and burns are major healthcare challenges, often healing slowly and leading to infections, pain, and high medical costs. Sine Hadrup’s project focuses on an enzyme that may worsen inflammation and delay healing of the injured skin. Sine Hardrup and her team will use artificial intelligence-driven protein design to create a small protein inhibitor (miBd) that blocks the enzyme, preventing its harmful effects. First, they will test whether miBds can bind and stop enzyme activity. Then, they will evaluate their impact on wound healing using human cell culture. Finally, they will test them in a pig skin model, as pig skin closely resembles human skin. Burns are introduced on the pig skin and treated topically with or without the miBds. If successful, this research could lead to new treatment options for wound healing and inflammatory skin diseases like psoriasis, offering better patient outcomes and faster recovery times.

Elucidating the complex role of NFκB signaling in skin development and dermatitis

Grantee: Rune Hartmann, Professor, Aarhus University, Denmark

Amount: DKK 3,924,000

Grant category: Research Grants

Year: 2025

Geography: Denmark

Multiple common skin diseases, like psoriasis, are characterized by excessive inflammation of the affected skin. This causes itching and pain and makes wound healing difficult. Thus, skin inflammation is of general discomfort for the affected patients. Anti-inflammatory drugs, for example inhibitors of the TNF signaling pathway, are highly successful in the clinic for some but not all types of skin inflammation. Rune Hartmann’s project aims at a better understanding of the underlying causes of skin inflammation and how to develop better drugs in the future. Furthermore, Rune Hartmann and his team are investigating how the same signaling pathway can drive skin inflammation and thus cause pathology, while being a critical part of healthy skin development. This is critical to understand how to target future drugs specifically towards the pathological inflammation and avoid unwanted side effects.

From Flexibility to Dysfunction: The Impact of Oxidative Stress on the Structural Integrity of Skin Elastin

Grantee: Andrea Heinz, Associate Professor, LEO Foundation Center for Cutaneous Drug Delivery, University of Copenhagen, Denmark

Amount: DKK 3,987,617

Grant category: Research Grants

Year: 2025

Geography: Denmark

Elastin is a structural protein essential for human life. It provides the elasticity needed for organs like skin, lungs, and blood vessels, allowing your skin to stretch, your lungs to expand for breathing and your blood to flow smoothly. As we age, factors like oxidative stress can make elastin stiffer, reducing the skin’s elasticity and accelerating the aging process. This can lead to skin conditions, such as thickening and furrowing or increased fragility. Andrea Heinz’ project uses advanced analytical techniques to investigate how oxidative damage affect elastin’s structure and stability, starting with its building block, tropoelastin, and extending to skin elastin. The goal is to understand how these alterations contribute to elastic fiber breakdown and tissue dysfunction. Ultimately, this knowledge will help them understand how elastin damage drives disease and tissue degeneration, which could lead to better treatments that protect tissue elasticity and improve overall health.

SERS-Enabled Wound-Sampling Patches for Rapid Infection Monitoring

Grantee: Gohar Soufi, Postdoc, Technical University of Denmark, Denmark

Amount: DKK 3,999,657

Grant category: Research Grants

Year: 2025

Geography: Denmark

Millions of people suffer from infected wounds each year, which can lead to serious complications or even death if untreated. Current methods for diagnosing wound infections are slow and require specialized laboratories. Gohar Soufi’s project aims to create a simple, portable device that uses advanced materials to detect infections quickly and accurately right at the patient’s bedside. This technology could revolutionize how infections are diagnosed, helping doctors start treatments sooner and improving patient outcomes.
