Title of diploma thesis: Investigation of proteolytic enzymes expression in different tissues at the transgenic animal model of Huntington's disease by means of biochemical and immunohistochemical methods Background: Huntington's disease (HD) is a neurodegenerative disorder that is caused by an expansion of a polyglutamine (polyQ) domain in the huntingtin (Htt) protein. Because it is known that mutant Htt and especially its small proteolytic fragments are toxic to neurons (particularly those in the striatum and cortex), it has been suggested that proteolysis of mutant huntingtin (mHtt) might play an important role in HD pathogenesis. Therefore, the aim of the present study was to examine the expression of endogenous and mtHtt and possible participation of the proteolytic enzymes from the group of caspases, matrix metalloproteinases (MMPs), kallikreins (KLKs) and calpains in HD pathology of brain tissue. Methods: In this study we used WT and TgHD minipigs for N-terminal part of the human mtHtt (548aaHTT-145Q, both F2 generation, age 36 months; F3 generation, age 48 months in additional experiment), R6/2 mice were used as...
