Stål and Wahlin group

Our group has a focus on metabolic and inflammatory liver diseases, and liver cancer. We perform clinical and translational studies on hereditary hemochromatosis, porphyric liver disease, non-alcoholic fatty liver disease, autoimmune hepatitis, primary biliary cholangitis and hepatocellular carcinoma. As hospital clinicians with collaborations with basic scientists, we are uniquely positioned to study liver disease from many different perspectives.

About our research

By using data from well characterized clinical patient cohorts, we can combine outcome data with findings from tissue analyses. We perform systematic biobanking of liver tissue, DNA and plasma, and have unique possibilities to study long-term prognosis and pathogenetic mechanisms of liver diseases. We also perform investigator-initiated prospective clinical trials on porphyria, non-alcoholic fatty liver disease and hemostasis in cirrhosis.

We have a large network of partners in both basic and clinical research departments, and we have access to advanced techniques for translational studies. Our prospective studies aim to find diagnostic and prognostic biomarkers of liver disease and liver cancer development, and to evaluate new treatments. Ultimately, we aspire to improve care for patients with liver disease.

Collaborations: The SweHep research network. The biobank is linked to the Swedish Register for Liver Cirrhosis.
Funding: Swedish Cancer Society.

4. Hemostasis in liver cirrhosis (HELICS)

The aim of the project is to evaluate new methods for hemostasis assessment in patients with liver cirrhosis or HCC.
Collaborations: Maria Magnusson (Coagulation Unit) and Charlotte Gran (Dept of Molecular Medicine and Surgery) KI.
Funding: Region Stockholm.

5. Characterization of circulating neo-antigens recognized by PD-1+ lymphocytes in HCC (CHANNEL)

Funding: Swedish Cancer Society.

6. Hepatopathy, cancer and comorbidity in acute hepatic porphyria
