About me

  • Personal statement


    I am Professor of Neurotoxicology at the Department of Neuroscience, Karolinska Institutet (KI), Stockholm, Sweden, and Director of the KI Ming Wai Lau Centre for Reparative Medicine. My clinical experience as an MD specialized in Child neuropsychiatry reinforced my belief in basic research as essential to move forward our understanding of neurodevelopmental disorders. My research has been developing through the last 30 years starting with a Dr Med Sci thesis on neuroendocrine mechanisms of stress hormone secretion at the Karolinska Institutet and a post-doctoral period at the Laboratory of Neurobiology and Behaviour at the Rockefeller University

  • New York. Upon my return to Sweden, I established my own research group at the Department of Toxicology of Karolinska Institutet and acquired a solid expertise in cellular mechanisms of neurotoxicity. 
  •  
  •  

  • My group studies the impact of adverse conditions linked to environmental and/or genetic factors on neurodevelopment with special reference to molecular mechanisms and functional outcome relevant to neurodevelopmental disorders. Since the very beginning my ambition was to address the complex issue of neurodevelopmental damage by using a comprehensive strategy stretching from behavioral to cellular and molecular analyses. To identify the intracellular mechanisms leading to neuronal damage, we have implemented many in vitro cell models including cell lines and primary cultures of different cell types related to the nervous system, such as neuronal and glial cells. Being interested in developmental neurotoxicity, we put a special effort in establishing relevant models based on neural stem cells. Using these models, we have made original contributions to characterize relevant pathways activated in programmed cell death/apoptosis induced by neurotoxic stimuli. A consistent part of my research has been devoted to the investigation of the neurodevelopmental effects of relevant environmental contaminants including MeHg, PFOS/PFOA, PCBs, Dioxins. 

  • A special focus has been on the effectes of high levels of the main stress hormones glucocorticoids (GC) on neurodevelopment.

Research

  • Research progression

     

  • The studies I made in the frame of my Dr. Med Sci. studies provided an important basis for understanding the neurochemistry and function of specific brain regions in the regulation of the response to stress. One of my major findings was achieved by using the novel marker for neuronal activity c-Fos which allowed the visualization of specific hypothalamic neuropeptidergic neurons activated by stress.

  • We have been the first group at Karolinska Institutet Solna that established a behavioral unit for the computerized analysis of rodent home-cage behavior, where animals are tested in their social environment with minimal stress. Our studies have clearly shown that the analysis of behavior is a first-choice approach to detect subtle modifications induced by neurodevelopmental insults induced by stress or exposure to environmental contaminants.

  • We have shown that high levels of glucocorticoids (GC) induce epigenetic modifications in genes critical for the regulation of cell proliferation, differentiation, migration, senescence, ion channels, mitochondrial function, and redox states. In in vivo studies in rodents, we observed alterations in hippocampal neurogenesis in male mice exposed to GC in utero, which develop depression-like behavior in adulthood. The appearance of depression is preceded by long-lasting disturbances in circadian activity and alterations in the expression of clock genes. Interestingly, our clinical investigations show that abnormal circadian activity patterns are present in depressed patients as well and the type of pattern of activity predicts the response to therapy. I and my closest collaborator, Dr. Stefan Spulber, patented this knowledge in the USA (PCT/EP2015/070644) and founded Northern Light Diagnostics AB.
