Forskningsbeskrivning

Our group performs translational immunological research studying tissue-resident natural killer cells in the human liver and uterus.

A key focus of the group is to gain insights into the basic biology of tissue resident NK cells in liver and uterus. Through unique collaborations with clinical units at the Karolinska University Hospital, we receive a high number of tissue samples. With respect to the uterus, key questions of interest include detailed characterization of the uterine NK cell KIR receptor repertoires, functional studies of uterine tissue resident NK cells, as well as trying to elucidate the ontogeny of uterine NK cells. In the liver we have a specific focus on human tissue-resident CD49a+ intrahepatic NK cells and study their phenotype, function, development, and role during liver diseases.

Moreover, we have an interest in the role of natural killer (NK) cells in the pathogenesis of liver diseases such as primary sclerosing cholangitis, steatohepatitis (NASH), and hepatitis virus infections (HBV, HCV, HDV). These diseases strongly predispose for tumor development in the human liver and we are also performing tumorimmunological studies evaluating the capacity of NK cells to recognize hepatocellular carcinoma and cholagiocarcinoma. Outside the liver, we also have an interest in NK-cell function during hemorrhagic fever virus infections.

Our studies include phenotypic and functional assessments of NK cells with a focus on differentiation, education, and functional and transcriptional regulation. We work with high-dimensional 22-parameter flow cytometry, CyTOF, microscopy techniques, and new tools for visualization and analysis of highly complex flow cytometry data including SPADE, SNE, and Citrus.
 

We function in close collaboration with other groups at Karolinska Institutet, including groups at the Center for Infectious Medicine. We participate in Karolinska Institutet - Hannover Medical School exchange program, in the International PSC Study Group network, and have multiple national and international collaborations.
