Mouse glial and neuroblastoma cells were infected with the mouse adapted strains C506 and 139A of scrapie agent. Lysates of the in vitro infected cells (from the 3rd to the 16th passage) intracerebrally inoculated into CD-1 mice, caused the development of a neurological disease, with characteristic signs of scrapie. Morphological changes in scrapie-infected neural cells were observed after about fifteen in vitro passages. In liquid medium, the cloning efficiency of these cells increased. They acquired the capacity to form large tridimensional colonies in agar. Heating the infectious brain extracts at 60 and 80 degrees C for 30 minutes did not inhibit these changes thus showing the involvement of the thermoresistant scrapie agent. Supernatants of scrapie-infected glial cells promoted colony formation in liquid medium with different types of normal cells. Analysis of supernatants of scrapie-infected mouse neuroblastoma cells showed a profound modification of neurotransmitter metabolism.
