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:
Beside coordinating the collection of biological samples (serum, plasma, cerebrospinal fluid) from patients with head injury and other central nervous system disorders, as well as the professional long-term storage of these samples, identification and measurement of the levels of protein biomarker molecules with diagnostic and prognostic potential for TBI, and perform complex analysis of the results in the light of other clinical patient data.
In the case of the so-called CENTER-TBI ("Collaborative European NeuroTrauma Effectiveness Research in TBI") project - funded by the FP7 mechanism of the European Union – the biomarkers were measured from serum samples collected from more than 3500 head injury patients from more than 50 sites across Europe between 2013 and 2021 with the participation of our Research Group – complex analysis and publication of the collected clinical and biomarker data is currently underway.
The maintenance of the "Pécs Severe Head Injury Database", (which was started in the summer of 2002 and contains clinical data of more than 700 severe head injury patients treated at the Neurosurgery Clinic of the University of Pécs) and the statistical analysis of the collected data for various purposes as well as publication of the results.
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.
