Winfried Pickl is M.D. and board certified specialist in immunology with 2 ½ years of international research experience at the Department of Molecular Biology and Genetics, Harvard Medical School. He is principal investigator and head of the Division of Cellular Immunology and Immunohematology and oversees the cellular diagnostics at the Institute of Immunology. Dr. Pickl has professional skills in molecular and cellular immunology, hematology as well as blood group serology and tissue typing. Moreover, he has extensive experience in project development and management, and extended academic teaching experience. He is the Speaker of the Doctoral Program Molecular, Cellular and Clinical Allergology, MCCA and Deputy Speaker. His research focuses on the specific interaction between professional antigen presenting cells and T cells. He and his group have rebuilt the allergen-specific immunological synapse with receptors relevant for the human disease. Along those lines human allergen-specific T cell receptors from mugwort and birch pollen allergic individuals have been cloned, characterized in vitro and introduced as trangens into HLA-expressing mice to create allergy-mice which react to the human relevant allergens of mugwort and birch pollen. Currently, in such mice, novel allergy vaccines, immunomodulatory drugs and state-of-the-art immunotherapies (CAR cells) are being evaluated.
