Curriculum vitae Professor Dr. Albert Becker

Research Interests

The major scientific interests ofour group focus on the neuropathological basis of epilepsies. Seizures frequently initiate in circumscribed areas of the brain. Many respectives patients are pharmacoresistant. By neurosurgical removal of the epileptogenic focus, seizures can often be controlled. Respective neurosurgical biopsies represent a unique prerequisite for molecular pathological approaches in order to provide an improved understanding of the etiology and pathogenesis to develop novel treatment strategies. Complementarily, we are using model systems of different complexity to gain insights in epileptogenesis, i.e. brain tissue reorganization after a transient insult that finally leads to a spontaneously epileptic focus. We have major research foci on acquired ion channelopathies in epileptogenesis, their underlying transcriptional control mechanisms and the role of ‘epileptic neurons’ as pacemakers of aberrant network synchronization. We further concentrate on the impact of aberrant microglia to neuron signalling in converting neuronal cells epileptic.

Techniques

We are using neuropathological, biochemical and molecular biological analyses in human brain biopsy tissue removed from focally epileptic patients undergoing neurosurgery for seizure control. Complementarily, we are characterizing transgenic mice in an epileptogenesis paradigm. Major relevant platform technologies are a rodent video-/EEG-monitoring unit, a viral transgenics unit run together with Prof. Schoch and an epilepsy neuropathology platform.
