Jacek Jaworski is a professor and deputy director for research at the International Institute of Molecular and Cell Biology (IIMCB) in Warsaw, where he leads the Laboratory of Molecular and Cellular Neurobiology. He started his career at the Nencki Institute of Experimental Biology where, in 2001, he completed his PhD under the supervision of Prof. Leszek Kaczmarek. Next he moved to the Picower Institute for Learning and Memory at MIT where he studied molecular mechanisms of neuronal development and neuronal structural plasticity. His most important discovery from this time concerns the first demonstration of the role of mTOR kinase in neuronal development. Subsequently, the research of his team at IIMCB has concentrated on molecular mechanisms responsible for proper neuronal morphology with a particular focus on mTOR-controlled cellular processes. In his recent work Prof. Jaworski also investigates how those processes contribute to neurodevelopmental pathology (e.g. epilepsy and tuberous sclerosis).

Katarzyna Mleczko-Sanecka carried out her doctoral and post-doctoral research in the laboratory jointly led by Martina Muckenthaler and Matthias Hentze, affiliated at the European Molecular Biology Laboratory (EMBL) and the University of Heidelberg. The main objective of her work was to gain new insights into the genetic control of iron homeostasis. To this end, she designed and conducted large-scale RNAi screens to systematically characterize regulators of hepcidin, the key iron-regulatory hormone. This work identified SMAD7 as an important hepcidin inhibitor and linked hepcidin control to proliferative signaling. In her further work, she also identified commonly used pharmaceuticals as hepcidin-modifying drugs. In 2017, she established her laboratory at the International Institute of Molecular and Cell Biology (IIMCB) – the Laboratory of Iron Homeostasis. Her group combines mechanistic cell-based studies (involving loss-of-function CRISPR knock-outs) with work on mouse models (using advanced flow cytometry, FACS and ‘omics’ approaches) to identify new molecular mechanisms involved in the maintenance of systemic iron balance. Specifically, the interests of the lab focus on ‘iron sensing’ in the liver, the control of iron deposition in hepatocytes, and on iron recycling by macrophages.

Gracjan Michlewski obtained his PhD and Habilitation from the Institute of Bioorganic Chemistry, Polish Academy of Sciences in Poznan, Poland. He carried out his postdoctoral research in the Human Genetics Unit, Medical Research Council in Edinburgh. In 2011, Gracjan established his laboratory at The Wellcome Trust Centre for Cell Biology, the University of Edinburgh with the Medical Research Council Career Development Award. Currently, he is the head of the Dioscuri Centre for RNA - Protein Interactions in Human Health and Disease at the International Institute of Molecular and Cell Biology in Warsaw and a Senior Lecturer (Zhejiang) in Biomedical Sciences at The University of Edinburgh.
The main objective of Gracjan Michlewski’s work is to gain new insight into RNA-protein interactions. He discovered a number of factors and mechanisms that regulate the production of miRNAs (short non-coding RNAs that control gene expression pathways). He also demonstrated that E3 ubiquitin ligase TRIM25 (a key player in the innate immune response to RNA viruses) is a novel RNA-binding protein. These findings have far-reaching consequences for our understanding of how RNA-binding proteins and metabolites regulate gene expression, RNA processing and innate immune response to RNA viruses.
