Our research group investigate different potential diagnostic, therapeutic possibilities and the clinical/functional outcome in case of traumatic brain injury (TBI) applying translational research strategies:

a,         Experimental neurotraumatotlogy:

Investigation of traumatic brain injury (TBI) with the utilization of our two licensed neurotrauma animal models: a) the impact acceleration head injury model – described by Marmarou et al. 1994 – and b) the fluid percussion head injury model – described first (for rats) by Dixon et al. 1987. Quantification of the impact of the injury – in strong collaboration with many other research groups of the Centre – involve histological methods (immunohistochemistry; silver staining methods), functional tests, measurement of protein biomarker levels as well as neuro-imaging (MRI, microCT) techniques. Investigation of histological, blood based biomarker and functional alterations – as a consequence of mild/repetitive mild TBI – represent the main focus of our recent experiments.

b,         Clinical studies in TBI:

Maintenance of the serum biobank with the serum samples from more than 3500 TBI subjects from around 60 sites across Europe as part of the CENTER-TBI (‘Collaborative European NeuroTrauma Effectiveness Research in TBI’) consortium. Protein biomarker assays, analyses as well as publication of the results are in progress in this project.

Further construction and targeted statistical analyses of the ’Pécs severe head injury database’ with the clinical and outcome data of all sTBI subjects treated by the Department of Neurosurgery from the 1st of July 2002 – so far the data of more than 700 consecutive cases were included.
