Research summary
Allergy is a chronic disease that is expected to affect more than 50% of all Europeans in 10 years' time. Recent break-through results demonstrate the correct administration of peanut to high-risk children significantly decreases their likelihood of developing allergy. We have demonstrated that cutaneous immune programming determines the systemic immune responses to allergens and identified a subset of immune cells residing in the epidermis, called “Langerhans’ cells (LCs)” playing a central role in the regulation of immunity and tolerance. Here we aim to investigate how the function human skin residing immune cells is altered in allergic skin disease, and whether we can use them to induce long-lasting tolerance to allergens.
We plan to investigate this process in skin samples collected from paediatric and adult patients, after obtaining an informed consent, and apply laboratory, clinical and computational methodologies to comprehensively characterise them. The clinical and immunological parameters will be correlated using the state-of-the –art computational tools, and the molecular targets key to the induction of allergen-specific responses or tolerance will be identified. These targets will be subsequently validated in laboratory experiments. By focusing on a key control element of immune regulation by human LCs, this work will define the molecular basis for the induction of immunotolerance, and identify targets for immune intervention in allergy.REC name
