Motoneuron disease is a term encompassing three phenotypes defined largely by the balance of upper versus lower motoneuron involvement, namely amyotrophic lateral sclerosis, primary lateral sclerosis and progressive muscular atrophy. However, neuroradiological and pathological findings in these phenotypes suggest that degeneration may exceed the neuronal system upon which clinical diagnosis is ...
Background and Objective: To study the effect of deprenyl on neuroprotective or survival on motoneuron and on gliosis reaction. Materials and Methods: Sprague Dawley rats (250-300 gr) of Razi institution were used to determine the effect of deprenyl (2.50 mg/kg ) on neuroprotective or survival on motoneuron and on gliosis reaction through morphometry and immunohistochemistry methods. Resu...
Spinal motoneuron development is regulated by a variety of intrinsic and extrinsic factors. Among these, a possible role for homeoproteins is suggested by their expression in the motoneuron at relatively late stages. To investigate their possible involvement in motoneuron growth, we adapted a novel technique recently developed in this laboratory, based on the ability of the 60 amino acid-long h...
Several studies have attempted to repair the damaged spinal cord (SC) by stimulating neurogenesis or neuroplasticity, with limited success. Sonic hedgehog (Shh) is involved in neural induction and stem cell functioning, but recent findings also suggest its role in regeneration and functional recovery. Transactive response DNA-binding protein of 43 kDa (TDP-43) is a nuclear DNA/RNA binding prote...
The survival of central neurons depends on multiple neurotrophic factors produced by different cell types. We demonstrate that media conditioned by muscle and Schwann cell lines show strong synergistic effects on survival of purified embryonic day 14.5 rat motoneurons in culture. Different lines of evidence implicate glial cell line-derived neurotrophic factor (GDNF) and cardiotrophin-1 (CT-1) ...
