In vivo monitoring van neuropeptiden tijdens epileptische aanvallen met nano LC-MS/MS en karakterisering van hun mogelijke anticonvulsieve rol. (IWT532)

Neuropeptides play an important role when the CNS is challenged such as for instance during epileptic seizures. In order to obtain better insights into the central peptidergic effects, it is essential to monitor their concentration in the brain. Quantification of neuropeptides in dialysates is challenging due to their low extracellular concentrations (low pM range), their low microdialysis efficiencies, the need for acceptable temporal resolution, the small sample volumes, the complexity of the matrix and the tendency of peptides to stick to glass and polymeric materials. The quantification of neuropeptides in dialysates therefore necessitates the use of very sensitive nano-LC-MS/MS methods. A number of LC-MS/MS and microdialysis parameters need to be optimized to achieve maximal sensitivity. The optimized and validated methods can be used to investigate the in vivo neuropeptide release during epileptic seizures, in this way initiating new and immense challenges for the development of new antiepileptic drugs.
