EXPERIMENTAL STUDY OF MECHANISMS OF NEURODEGENERATION IN DIFFERENT CONDITIONS - SUMMARY MUDr. Zdeňka Purkartová The cerebellum is an important structure involved in motor coordination and many other functions including cognitive and emotional processes. Severe cerebellar diseases include a wide group of cerebellar hereditary degenerations with different types of heredity, different pathogenesis and diverse phenotypic manifestation. Many types of mouse models can be used to investigate these diseases and their therapy. These mice carry spontaneous mutations or are genetically modified. The aim of this work was to analyse the dynamics of morphological changes of cerebellar degeneration in Lurcher mice using fluorescent double staining. We also performed transplantation of embryonic cerebellar tissue suspension in adult Lurcher B6CBA mice, B6.BR mice and wild-type mice of both strains with two-month survival after surgery and transplantation of identical suspension in adult Lurcher B6CBA mice and C3H mice and wild- type mice of both these strains with six-month survival after surgery. We have confirmed these main characteristics of the degenerating Purkinje cells in Lurcher mutants: the disrupted continuity of the Purkinje cell layer, the presence of dark spots in the cell nuclei, the fragmentation of nuclei... |
