Modelování Huntingtonovy choroby a bněčná terapie při poškození míchy.

Neurological disorders affect more than 14% of the population worldwide and together with traumatic brain and spinal cord injuries represent major health, public and economic burden of the society. Incidence of inherited and idiopathic neurodegenerative disorders and acute CNS injuries is growing globally while neuroscience society is being challenged by numerous unanswered questions. Therefore, research of the CNS disorders is essential. Since animal models of the CNS diseases and injuries represent the key step in the conversion of the basic research to the clinics, we focused our work on generation of new animal models and on their use in pre-clinical research. We generated and characterized transgenic minipig model of Huntington's disease (HD) which represents the only successful establishment of a transgenic model of HD in minipig which should be valuable for testing of long term safety of HD therapeutics. Next, we crossed the well characterized R6/2 mouse HD model with the gad mouse model which lacks the expression of UCHL1 which led to results that support the theory of "protective" role of mutant huntingtin aggregates and suggest that UCHL1 function(s) may be affected in HD disturbing certain branches of Ubiquitin Proteasome System. Traumatic spinal cord injury and Amyotrophic Lateral...Neurologické poruchy postihují více než 14 % světové populace a společně s traumatickým poškozením mozku a míchy představují významnou zdravotní a socioekonomickou zátěž. Výskyt dědičných a idiopatických neurodegenerativních poruch a akutních poškození CNS navíc zaznamenává globální nárůst a neurovědecká komunita je proto stavěna před množství nezodpovězených otázek. To je důvodem, proč lze pokládat výzkum poruch CNS za klíčový. Vzhledem k tomu, že zvířecí modely nemocí a traumatických poškození CNS mají nepostradatelnou úlohu v projekci výsledků základního výzkumu do klinické praxe, tato práce je zaměřena na vytvoření nových zvířecích modelů a jejich využití v preklinickém výzkumu. Vytvořili a charakterizovali jsme transgenní model miniaturního prasete pro Huntingtonovu chorobu, jenž je doposud jediným prasečím modelem a představuje velice hodnotný subjekt pro dlouhodobé testování bezpečnosti léčby. Dále jsme zkřížili již charakterizovaný myší model Huntingtonovy choroby s myším modelem gad postrádajícím expresi UCHL1 s výsledky, které potvrzují teorii o "ochranné" funkci agregátů mutovaného huntingtinu a vedou k předpokladu, že funkce UCHL1 v ubiquitin proteazomového systému mohou být v Huntingtonově chorobě narušené. Traumatické poškození a amyotrofická laterální skleróza (ALS) jsou dvěma...Department of Cell BiologyKatedra buněčné biologieFaculty of SciencePřírodovědecká fakult
