About me

  • I got my education at the Karolinska Institute and have had positions as
    professor of “biochemical research on atherosclerosis” and senior
    physicican in Clinical Chemistry during the years 1986-2008. I am senior
    professor at the division of clinical chemistry, department of laboratory
    medicine, at the Karolinska University Hospital Huddinge since 2012. At
    present I work about 70% with research.

  • I have worked on different aspects of cholesterol since 1963 when I started
    my PhD studies. In particular I have been involved in the elucidation of the
    mechanisms and regulation of the enzymes involved in the degradation of
    cholesterol into bile acids. During the last two decades I have focused on
    the regulatory mechanisms behind cholesterol homeostasis in the brain, and in
    particular the role of oxysterols. We made the key discovery that side-chain
    oxidized oxysterols , in contrats to cholesterol, are able to pass the
    blood-brain barrier. We have shown that these oxysterols are important for
    regulation of cholesterol synthesis, glucose uptake by the brain, generation
    of beta amyloid and several other processes. We utilize unique mouse models
    as well as clinical materials in our research involving collaborations with
    different clinical disciplines.
