Friedreich ataxia: metal dysmetabolism in dorsal root ganglia

BACKGROUND Friedreich ataxia (FA) causes distinctive lesions of dorsal root ganglia (DRG), including neuronal atrophy, satellite cell hyperplasia, and absorption of dying nerve cells into residual nodules. Two mechanisms may be involved: hypoplasia of DRG neurons from birth and superimposed iron (Fe)- and zinc (Zn)-mediated oxidative injury. This report presents a systematic analysis of DRG in ...

Friedreich ataxia mouse models with progressive cerebellar and sensory ataxia reveal autophagic neurodegeneration in dorsal root ganglia.

Friedreich ataxia (FRDA), the most common recessive ataxia, is characterized by degeneration of the large sensory neurons of the spinal cord and cardiomyopathy. It is caused by severely reduced levels of frataxin, a mitochondrial protein involved in iron-sulfur cluster (ISC) biosynthesis. Through a spatiotemporally controlled conditional gene-targeting approach, we have generated two mouse mode...

Peroxisomes in dorsal root ganglia.

Bodies with the morphologic and cytochemical characteristics of peroxisomes have been identified in the satellite and Schwann cells of rat dorsal root ganglia. They are membrane-delimited, round or oval structures which contain a moderately electron-dense matrix but lack a crystalline core. On incubation of the tissue in a cytochemical medium for demonstration of peroxisomes, these bodies show ...

Paclitaxel-Resistant Neurons in Dorsal Root Ganglia

Paclitaxel is an antineoplastic drug, and its usage is often limited by severe peripheral polyneuropathy characterized by symptoms in remote extremities. It is suggested that subpopulations of dorsal root ganglion (DRG) neurons are impacted functionally and/or structurally. In this study, the neurotoxic effect of this drug in cultured rat DRG neurons was analyzed by measuring their neurite leng...

Neurogenesis in postnatal mouse dorsal root ganglia.

Neurogenesis continues in various regions of the central nervous system (CNS) throughout life. As the mitogen basic fibroblast growth factor (bFGF) can proliferate neuronal precursors of CNS neurons in culture, and is also upregulated within adult dorsal root ganglia following axotomy, it is possible that the postnatal dorsal root ganglia contain bFGF-responsive neuronal precursors. We undertoo...
