Mihai Netea was born and studied medicine in Cluj-Napoca, Romania. He completed his PhD at the Radboud University Nijmegen, The Netherlands, on studies investigating the cytokine network in sepsis. After working as a post-doc at the University of Colorado, he returned to Nijmegen where he finished his clinical training as an infectious diseases specialist, and where he currently heads the division of Experimental Medicine, Department of Internal Medicine, Nijmegen University Nijmegen Medical Center. He is mainly interested in understanding the memory traits of innate immunity (trained immunity), the factors influencing variability of human immune responses, and the immune dysregulation during bacterial and fungal infections. He is the recipient of the Spinoza Prize 2016 and an ERC Advanced grant in 2019, and since 2016 he is a member of the Netherlands Royal Academy of Sciences (KNAW).

Katri Lindfors, Celiac Disease Research Center, Faculty of Medicine and Health Technology, Tampere University: Phenotypic spectrum of celiac disease – a quest for underlying mechanisms

Please register latest May 6th at  https://link.webropolsurveys.com/S/EE67FF858AC0A584

Host: Riitta Lahesmaa ( rilahes[ät]utu.fi )

Katri Lindfors is a professor of molecular biology and the vice director of Celiac Disease Research Center at Tampere University. She is a member of the organizing committee of the Tampere Celiac Disease Symposium, the scientific advisory board of the patient organization Finnish Celiac Society and International Society for the Study of Celiac Disease.

She has conducted translational celiac disease research over 20 years and published over 100 peer-reviewed articles. Her previous work has contributed to the understanding of factors involved in celiac disease pathogenesis including the potential role of enteroviruses as a triggering factor and the biological functions of celiac disease specific autoantibodies targeting a self-protein transglutaminase 2 (TG2).  Currently her group focuses on identifying factors contributing to the heterogenous clinical picture of celiac disease using dermatitis herpetiformis, the skin manifestation of celiac disease, as a model phenotype. Up to now, her results indicate that in addition to a distinct genetic predisposition, an autoimmune response against a TG3, a homologue of celiac disease autoantigen TG2 is implicated in dermatitis herpetiformis. Ongoing studies are addressing the questions whether dermatitis herpetiformis pathogenesis is initiated in the small bowel mucosa and how the disease spreads from gut to skin as a consequence of unrecognized and untreated celiac disease.

Eliisa Kekäläinen, M.D. Ph.D., research group is based at the University of Helsinki, and is part of Translational Immunology Research Program. Eliisa Kekäläinen has wide interest in immunodeficiency diagnostics and immunological tolerance. Her research focuses especially on the primary immunological organ the thymus. She is interested in how e.g. common viral infections and hematopoietic stem cell transplantation affect thymus function, how they could better measure thymopoiesis in clinical situations, and what kind of pathological processes in the thymus lead to immunodysregulation in autoimmune diseases such as myasthenia gravis. Eliisa Kekäläinen works also at the HUS Diagnostic Center Clinical Microbiology and Immunology (Helsinki University Hospital) where she mainly focuses on immunodeficiency laboratory diagnostics.
