Amyloid β-protein oligomers upregulate the β-secretase, BACE1, through a post-translational mechanism involving its altered subcellular distribution in neurons
Quantification of fluorescence intensities in axons and dendrites. After double immunofluorescent staining of primary neurons with anti-BACE1 (green) and anti-MAP2 (red) antibodies, specimens were examined under a LSM780 microscope. BACE1 fluorescence intensities along MAP2-positive dendrites (red line) and MAP2-negative axons (blue line) were quantified as described in Methods. Scale bar = 10 μm. (PDF 66 kb
Enlargement of the brachial plexus on magnetic resonance imaging: a novel finding in adult-onset Krabbe disease
Adult-onset Krabbe disease is an autosomal recessive degenerative leukodystrophy that presents with bilateral corticospinal tract involvement on MRI. Although peripheral nerve involvement is a known manifestation of Krabbe disease, MRI findings of peripheral nerve abnormalities are limited to the cranial nerves and spinal nerve roots. In this case report, we discuss two cases of adult-onset Krabbe disease with brachial plexus enlargement on MRI. Adult-onset Krabbe disease should be included in the differential diagnoses when brachial plexus enlargement and white matter lesions involving corticospinal tracts present simultaneously
