The distal to proximal degeneration of axons, or "dying back" is a common pattern of neuropathology in many diseases of the PNS and CNS. A long-standing debate has centered on whether this pattern of neurodegeneration is due to an insult to the cell body or to the axon itself, although it is likely
Vincristine is known to be toxic to neural tissue, where it is thought to react with microtubules and impair axonal transport. Intravitreous vincristing-induced changes of the retina have been reported to be reversible after 10 micrograms. In the present study, the effects of 0.01 to 100 micrograms
Fifteen patients with Hodgkin's disease were examined before and after each administration of vincristine sulfate (2 intravenous injections of 1.4 mg/m2 of body surface, during the first week of each month for 3 months). Moreover, each patient received daily, according to a double blind protocol,
The effect of topical application of axonal transport blockers to the transected peripheral nerve was assessed by quantitating the strychnine-enhanced transsynaptic degeneration following transection of the inferior alveolar nerve in adult rats. Systemic administration of strychnine (1 mg/kg/day)
Bilateral optic atrophy developed in a 15-year-old patient receiving concomitant neuraxis radiation therapy and weekly vincristine sulfate for medulloblastoma. Other neurologic manifestations that have been associated with vincristine therapy, including inappropriate secretion of antidiuretic
Peripheral neuropathies and Wallerian degeneration share a number of pathological features; the most prominent of which is axonal degeneration. We asked whether common pathophysiologic mechanisms are involved in these 2 disorders by directly comparing in vitro models of axonal degeneration after
Suppression of inhibition of axonal outgrowth and promotion of axonal protection from progressive axonal degeneration are both therapeutic strategies for the treatment of neuronal diseases characterized by axonal loss. Myelin-associated inhibitors (MAIs) have been shown to suppress axonal outgrowth,
Axon degeneration is a prominent feature of various neurodegenerative diseases, such as Parkinson's and Alzheimer's, and is often characterized by aberrant mitochondrial dynamics. Mitochondrial fission, fusion, and motility have been shown to be particularly important in progressive
Neurological diseases are frequently associated with axonal degeneration, which leads to dysfunction though separation of neurons from their targets. The mechanisms of axonal degeneration are largely unknown and in many cases are independent of those occurring within cell bodies in neurodegenerative
Chemotherapy-induced peripheral neuropathy is one of the most prevalent dose-limiting toxicities of anticancer therapy. Development of effective therapies to prevent chemotherapy-induced neuropathies could be enabled by a mechanistic understanding of axonal breakdown following exposure to
BACKGROUND
Severe up to life-threatening neuropathy has been observed in patients with hereditary neuropathies receiving vincristine.
METHODS
A 52-year-old female painter suffering from high-grade non-Hodgkin's lymphoma (stage IVB) was treated with a total of 4 mg of vincristine during two courses
