Project description:Darier disease (DD) is a rare, inherited multi-organ disorder associated with mutations in the ATP2A2 gene. In DD patients, the skin is frequently affected, characterized by malodorous, inflamed skin and recurrent, severe infections. Therapeutic options are limited and inadequate for the long-term management of this chronic disease. Using immunoprofiling with NanoString technology we demonstrate enhanced expression of Th-17-related genes and cytokines in five DD patients. We prove that targeting the IL-23/-17 axis in DD with monoclonal antibodies is an effective and safe therapy in DD patients, leading also to significant clinical improvement.

In DD patients, the skin is frequently affected, characterized by malodorous, inflamed skin and recurrent, severe infections. Therapeutic options are limited and inadequate for the long-term management of this chronic disease. Using immunoprofiling with NanoString technology, qPCR and immunohistochemistry, we demonstrate enhanced expression of Th-17-related genes and cytokines in six DD patients. We prove that targeting the IL-23/-17 axis in DD with monoclonal antibodies is an effective and safe therapy in DD patients, leading to significant clinical improvement. As DD is a chronic, relapsing disease, our findings provide new options for the long-term management of skin inflammation in patients with DD.
Project description:Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic destructive arthritis. Although helper T cells are involved in the pathogenesis of RA, the characteristics of synovium-infiltrating CD4+ T cells are still largely unknown. In this study, we investigated synovium-infiltrating helper T cells of rheumatoid arthritis patients
