Conditions of prion propagation in cell cultures
 Hobzová, Kristýna ; Janoušková, Olga (advisor) ; Rusina, Robert (referee)
Prion diseases are fatal neurodegenerative diseases that affect mammals, including humans, which are characterized by accumulation of pathologi- cal prion protein isoform (PrPTSE ) in the brain. The animals were commonly used for the prion disease research in the past but in recent years, the tissue cultures are being used as well. Tissue cultures have many advantages com- pared with animals. E.g. the possibility of a detailed study of the biochemical processes associated with prion diseases, and rapid and sensitive PrPTSE de- tecting method. However no reliable in vitro model was developed for human prion diseases so far. We focused on monitoring of transmission and propagation efficiency of different prion strains and on the influence of cultivation conditions on the transfer of the neuronal cell line CAD5, which is highly sensitive to prion infection. We confirmed the sensitivity of CAD5 cells to mouse-adapted scra- pie prion strains and we presented new facts about their ability to propagate mouse adapted prions of human strains and bovine spongiform encepha- lopathy. We have used CAD5 cell sensitivity to be infected with different prion strains in other parts of this work. In the second part, we focused on the cell sensitivity to prion infection and propagation of prion strains under different culture...
