PhD in the field of animal immunology and molecular biology at the University of Warmia and Mazury in Olsztyn (Poland)

 Karol Mierzejewski received his PhD in the field of animal immunology and molecular biology at the University of Warmia and Mazury in Olsztyn (Poland). His doctoral thesis focused on the influence of PPAR-gamma ligands on the regulation of the immune response in the endometrium of pigs with LPS-induced inflammation. He has completed several internships, e.g. at the Department of Veterinary Medicine at the University of Milan, the Institute of Marine Research at the Spanish National Research Council in Vigo, and the Biomedical Research Center at the University of Vigo. He currently works as an assistant professor at the Department of Animal Anatomy and Physiology at the University of Warmia and Mazury in Olsztyn. The aim of his current research is to investigate the effects of polyethylene terephthalate (PET) microplastics (one of the most commonly used plastics in food packaging) on the content of extracellular vesicles (EVs) isolated from selected body fluids (blood, bile and urine), as well as the transcriptomic, proteomic and metabolomic profiles of different tissues (liver and kidney), which are the main source of EVs in bile and urine. In his research, he uses high-throughput methods such as RNA-Seq for transcriptome analysis and liquid chromatography/tandem mass spectrometry (LC-MS/MS) for proteome and metabolome analysis.
