- In this thesis, the detection of global proteomics alteration and changes in neuropeptide distribution caused by neuropathic pain in rat spinal cord tissue was the main focus. Neuropathic pain (NP) is a major clinical syndrome caused by disease or dysfunction of the nervous system and often mediated by neuronal networks in the spinal cord. The estimated prevalence of NP is 6-8% in general population. Only in the United States, the indirect cost associated with chronic pain has been estimated to 100 billion dollars each year and NP substantially contributes to this cost. So far, the underlying mechanisms of NP are not well understood. Proteomics techniques are commonly used in biology system studies, due to its high throughput, capability of unbiased analysis and sensitivity. It builds up a bridge to link genes, peptides, proteins, and the disease. Two proteomic/peptidomic approaches were developed, evaluated and discussed in this thesis. Both of them were further applied in the studies of neuropathic pain. First approach is a quantitative proteomic approach using liquid chromatography combined with Fourier transform mass spectrometry (LC-FTMS), which is developed for quantitative analysis of proteins originated from small central nervous system (CNS) samples. This approach was successfully applied in the study of the rat spinal cord tissue proteome in a neuropathic pain model. Another approach is using matrix assisted laser desorption ionization mass spectrometry (MALDI-MS) for the visualization of the distribution of neuropeptides in rat spinal cord, which in the future will be applied in investigating the ongoing signal transmission under neuropathic pain conditions. Results provided by these two methods are of high importance for the general understanding of the underlying pathophysiological mechanisms and potential identification of new targets for novel treatment of neuropathic pain.
