The Center for Research and Training in Skin Diseases and Leprosy (CRTSDL) is affiliated to TUMS, the first and largest modern medical university in Iran, founded in 1934. Established in 1992, the CRTSDL is located close to the main TUMS campus in central Tehran and is Iran's oldest and best-known dermatology research centre. The centre is devoted to research and training on various aspects of skin diseases and leprosy. Over the past 25 years, much of its work has focused on studying leishmaniasis, including clinical trials on vaccine and drug evaluation conducted in collaboration with partners including the WHO's Special Programme for Research and Training in Tropical Diseases (TDR), the WHO Regional Office for the Eastern Mediterranean (EMRO), Sweden's Karolinska Institute and Janssen-Cilag. The CRTSDL's team comprises dermatologists, dermato-pathologists, pharmacists, general practitioners, immunologists, basic science experts, researchers, graduate students, technicians, and administrative staffs. Staff at the Center are trained to work under good clinical practice (GCP) guidelines and can conduct studies ranging from laboratory bench to human clinical trials.
