Abstract

The thesis is divided in one chapter, which was dedicated to peptidomic analysis of the striatum in the 6-OHDA mice model and also to oligopeptidase activity such as EP 24.15 and EP 24.16. The second chapter refers to data obtained during a research internship in the Max-Planck Institute of Psychiatry, Munich, Germany, in which we ran peptidomic analysis of post-mortem samples of the anterior temporal lobe and corpus callosum from schizophrenia patients. Both projects used mass spectrometry techniques such as isotopic labeling and label free applied to LC-MS/MS. In the Parkinsons disease model we observed significant changes in 5 different peptide fragments, and for schizophrenia samples, 2 peptide fragments were biologically different. The resulting data acquired in both projects lead to a substantial increase in prospective possibilities to new targets associated to the disorders studied here. (AU)
