Image of the Month: SCA1-like neurodegeneration
In a mouse model of spinocerebellar ataxia type 1 (SCA1), mice carrying mutant Pumilio1 genes develop progressive motor deficits and cerebellar degeneration. Studies conducted by the Zoghbi lab and colleagues have revealed, as shown in these images, dramatic differences in the arborization of Purkinje cells (neurons located in the cerebellar cortex of the brain) when comparing wild type (left), Pum1 +/- (middle) and Pum1 -/- (right) mice. (The images show immunofluorescence confocal microscopy in 3D depth-coding, 63X).
