• neurogenesis
  28 January 2006

  During the development of the mammalian central nervous system, neural stem cells and their derivative progenitor cells generate neurons by asymmetric and symmetric divisions. The proliferation versus differentiation of these cells and the type of division are closely linked to their epithelial characteristics, notably, their apical-basal polarity and cell-cycle length.

• SPG7-associated hereditary spastic paraplegia
  27 January 2006

  Muscle biopsies from the autosomal recessive form of patients with hereditary spastic paraplegia revealed histochemical signs of a mitochondrial disorder, namely RRFs, COX-negative fibres and succinate dehydrogenase-positive hyperintense fibres.
  Linkage and subsequent mutation analysis revealed large deletions in a gene dubbed paraplegin. Owing to the homology with a yeast mitochondrial ATPase with both proteolytic and chaperone-like activities, it has been suggested that this form of (...)

• hereditary neuralgic amyotrophy
  5 October 2005

  Definition: Hereditary neuralgic amyotrophy (HNA) is an autosomal dominant form of recurrent focal neuropathy characterized clinically by acute, recurrent episodes of brachial plexus neuropathy with muscle weakness and atrophy preceded by severe pain in the affected arm. Hereditary neuralgic amyotrophy can be caused by mutations in the SEPT9 gene (604061).
  Hereditary neuralgic amyotrophy (HNA) is an autosomal dominant recurrent neuropathy affecting the brachial plexus. HNA is triggered by (...)
