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...
متن کاملRole of a voltage-sensitive calcium channel blocker on inhibition of apoptosis in sensory neurons of cultured dorsal root ganglia in adult rat
Introduction: Under pathological conditions, abnormal increase in intracellular calcium concentrations is believed to induce cell death. In the present study, a voltage-sensitive calcium channel blocker (loperamide hydrochloride) was used to investigate its role in inhibition of apoptosis in sensory neurons of cultured spinal dorsal root ganglia (DRG). Methods: L5 DRG from adult rats were di...
متن کاملSubstance P-like immunoreactivity in neurons in dissociated cell cultures of mammalian spinal cord and dorsal root ganglia.
Dissociated cell cultures prepared from fetal mouse spinal cords and dorsal root ganglia were stained for endogenous substance P using the peroxidase-antiperoxidase technique. Substance P-like immunoreactivity was localized within a small percentage of rounded or multipolar neuronal somata and in varicose processes. The substance P-positive multipolar neurons were derived from spinal cord, whil...
متن کاملTime course of substance P expression in dorsal root ganglia following complete spinal nerve transection.
Recent evidence suggests that substance P (SP) is up-regulated in primary sensory neurons following axotomy and that this change occurs in larger neurons that do not usually produce SP. If this is so, then the up-regulation may allow normally neighboring, uninjured, and nonnociceptive dorsal root ganglion (DRG) neurons to become effective in activating pain pathways. By using immunohistochemist...
متن کاملPeroxisomes 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 ...
