Separation of electrical charges on the plasma membrane of the cell achieved by the complex balance of activities of different ion channels, transporters and pumps is a fundamental principle of life form organization. Dysfunctions of ion channels or their regulation causes a number of human diseases ranging from epilepsy to sudden cardiac death. We study function and regulation of ion channels and, in larger perspective, regulation of cellular excitability. Particular focus of the group is the regulation of excitability of peripheral pain-sensing (nociceptive) neurones in relation to pain signalling. We investigate the regulation of ion channels that control or influence excitability and synaptic transmission of nociceptors (e.g. KCNQ or M channels, Ca2+-activated Cl- channels, sensory TRP channels and voltage-gated Ca2+ channels). Our group is also interested in the modulation of different neuronal ion channels by G protein coupled receptors (GPSRs) and in GPCR signalling networks of sensory neurones. One of the latest projects is aimed at the investigation of the transcriptional regulation of neuronal K+ channels in chronic pain states.

We use a wide range of the cutting-edge methods and techniques which allow us to follow our research questions from the level of individual molecules and up to the whole-organism level. Thus we use biochemical and molecular biological approaches to study individual proteins and genes; we use electrophysiology (patch-clamp and voltage clamp) and bioimaging methods (including live confocal and TIRF microscopy) to study individual cells and, finally, we use various behavioural approaches to probe neuronal signalling in vivo.
