- The human brain (lat. cerebrum ) is the most complex and heterogeneous organ in the human body. It is involved in a great number of body functions like movement, touch sensing, vision, hearing, smelling, hormone regulation and many more. In no other organ, the molecular communication mechanisms between different cells are so poorly understood. Due to the extensive diversity of processes that are controlled by the brain, diseases and injuries of the nervous system affect the human body significantly. Because of the immense complexity of the brain, the molecular mechanisms underlying the pathology of the diseases remain largely unknown. Hence, there is an urgent need for the development of new analytical strategies in order to investigate these conditions on a molecular level. Here, a central focus lies in the study of protein and peptide expression profiles, which can provide an insight in ongoing molecular mechanisms underlying the pathophysiology of the diseases. A powerful approach for studying proteins and peptide dynamics is mass spectrometry based proteomics, which is defined as the comprehensive study of all proteins expressed in a biological matrix at a certain point of time. The central objective of this thesis was to develop and employ different mass spectrometric techniques to study protein and peptide dynamics in the central nervous system in different neurological diseases. The individual studies comprise different aspects of proteome research. The first two studies included clinical proteomic applications for investigating protein dynamics in traumatic brain injury and amyotrophic lateral sclerosis. A further study was focused on method development for MS analysis of intact neural cells. The final three projects described in this thesis comprised MS based protein and peptide imaging in brain and spinal cord tissue samples. Here, the aim was to elucidate topological changes in protein expression in ALS as well as neuropeptide alterations in distinct brain structures in L-DOPA induced dyskinesia (LID) in Parkinson’s disease.
