Our research interests contain two main focuses. 1. Drug hypersensitivity. Our lab is the first and only in Southeast Asia to establish in vitro testing for the identification of culprit drugs in immediate and delayed-type drug hypersensitivity. We also continue to improve the in vitro test for drug hypersensitivity, aiming to be the leader of the drug hypersensitivity center in the Asia-Pacific region. 2. Research and development of investigations for clinical problems. Through clinical collaboration, we have conducted basic immunological research to support diagnosis and investigation across many clinical fields. Aesthetic medicine Botulinum toxin treatment failure (BTF) Development of an in vitro test for BTF Investigation of risk factors associated with BTF Biostimulators and fibroblast Investigation of immunological involvement in biostimulators for aesthetic Chronic urticaria Development of an in vitro test for chronic urticaria Investigation of immunopathogenesis of chronic urticaria Sweat allergy Development of an immunological test for the diagnosis of sweat allergy Mesenchymal stem cell (MSC): Immunological involvement and aesthetic treatment Bone marrow-derived MSC Adipose-derived MSC
