My research addresses fundamental aspects of basic pharmacology, molecular pharmacology and neuropharmacology, with certain potential translational parts. The work is divided into three Work Packages each containing a number of specific projects. Work Package 1 is focused on the pharmacology of PSD95/Disc-large/ZO-1 homology (PDZ) mediated proteins-protein interaction and how these domains might represent new attractive pharmacological targets as alternatives to surface receptors. Work Package 2 will seek to explore the controversial idea that trafficking of receptors and transporters, which in many cases is strongly integrated with their pharmacology, is determined not only by protein-protein interactions, but also by yet unappreciated protein-lipid interactions that govern localization of the receptors and transporters to areas of high membrane curvature in the plasma membrane. Work Package 3 is aimed at obtaining fundamental new understanding of dopamine signaling processes in the brain. Evidently, this has broad pharmacotherapeutic perspectives given the key role of dysfunctional dopamine signaling in many brain disease including schizophrenia, bipolar disorder, ADHD, Parkinsons’ Disease and drug abuse.

Scientific focus areas
Neurobiology and neuropharmacology with special attention given to the dopamine system and glutamate receptor trafficking during synaptic plasticity in health and disease. Protein-lipid and protein-protein interactions and their pharmacology (particularly PDZ domains). Main methods: advanced light microscopy, including live microscopy and fluorescence energy transfer (FRET) and total internal reflection (TIRF) microscopy.
The research group currently constitutes 10 persons.
- Protein trafficking of transmembrane proteins (by flowcytometry, confocal microscopy, TIRF microscopy of pHluorin)
- Neuronal signaling (by live fluorescence imaging of FRET based biosensors for PKA, PKC etc)
- Nano-structures of receptor-Scaffold complexes and membrane structures (by super resolution microscopy and 'supported cell membrane sheets’)
- Protein-protein interactions (in vitro by fluorescence polarization, SPOT, ex vivo/in vivo by Co-IP and Bio-ID)
- Semi-high throughput screening (by fluorescence polarisation)
- Protein-lipid interactions (by flow cytometry and SPOT)
