Taija Mäkinen obtained her PhD from the University of Helsinki and
completed postdoctoral training at the Max Planck Institute of
Neurobiology in Martinsried, Germany. She previously served as a group
leader at the Cancer Research UK London Research Institute (now the
Francis Crick Institute) and later as Professor at Uppsala University.
In 2024, she returned to Finland and currently serves as Director of the
Wihuri Research Institute and Professor at the Faculty of Medicine,
University of Helsinki. Her research focuses on the mechanisms
regulating the lymphatic vascular system and its roles in health and
disease.

Immunology seminar series is jointly organised by the Finnish Society for Immunology, InFLAMES Flagship and Turku Bioscience. For further information contact Anne Lahdenperä ( ankahy[ät]utu.fi ) or Riitta Lahesmaa ( rilahes[ät]utu.fi ), University of Turku.
Pärt Peterson is a Professor of Molecular Immunology and Head of the Institute of Biomedicine and Translational Medicine at the University of Tartu, Estonia. He defended his PhD in molecular immunology in 1996 at the University of Tampere, Finland and he has been a Fellow of the Finnish Academy, The Wellcome Trust International Senior Fellow, and the Research Professor of the Academy of Estonia. Since 2008, he has been a Professor of Molecular Immunology at the University of Tartu, Estonia. Year 2023 he was elected member of the Estonian Academy of Sciences.
Pärt Peterson leads Molecular Pathology Research Group at the University of Tartu. His main focus is to understand the transcriptional and epigenetic regulation in cells involved in immune response and tolerance. His research interest has focused on the Central immune tolerance and the function of the Autoimmune Regulator (AIRE) gene in the thymus. His second research direction is Immunopathology of APECED (or APS1) disease, in which patients develop multiple endocrine autoimmune disorders and chronic mucocutaneous candidiasis. He co-discovered and made initial characterization of the DNA methyltransferase 3-like (DNMT3L) gene, a regulator of DNA methylation and epigenetic imprinting. Pärt Peterson group studies the role of autoantibodies to type 1 interferon and other cytokines, and their presence among autoimmune patients and in aged individuals and also age-related changes in old individuals to understand the molecular and cellular drivers of these processes. They combine molecular and cellular approaches with immunology tools and use genome-wide transcriptomic and epigenetic analyses, also single-cell approaches on immune cells.

PhD Jonna Alanko is a Principal Investigator at the Turku Bioscience Centre, University of Turku and Åbo Akademi University, and the winner of the Scandinavian Society for Immunology (SSI) Young Investigator Award 2025 from Finland. Jonna completed her PhD in 2016 in Prof. Johanna Ivaska’s group at the University of Turku, after which she conducted extensive postdoctoral research abroad in Prof. Michael Sixt’s group at the Institute of Science and Technology Austria (ISTA). After returning to Finland, Jonna continued her career as an InFLAMES Postdoctoral Fellow in Prof. Marko Salmi’s group until securing funding for her own research group (InstruFellow and Academy Research Fellow).
Jonna and her Immune Cell Navigation group investigate how immune cells—particularly dendritic cells—migrate and navigate in response to different molecular cues, using various live-cell migration setups (https://bioscience.fi/immune-cell-navigation/). Jonna’s previous work revealed dendritic cell–generated CCL19 gradients as a previously unknown guidance mechanism, and her group is now continuing this research to open new avenues for understanding immune responses. Their research aims to uncover the detailed mechanisms of leukocyte navigation, with the ultimate goal of therapeutically manipulating these mechanisms to guide cells to desired locations, such as toward tumors or away from autoimmune sites.
