Involvement of Mice Hippocampus Brain-derived Neurotrophic Factor in Diazinon-induced Depressive Behavior in Mice
Background: Diazinon (Dzn), an Organophosphorus (OP) pesticide, is extensively used in agriculture. Acetylcholinesterase inhibition is linked to OP toxicity, and there are major mental health concerns associated with the use of pesticides. The objective of this study was to assess the depressive behavior in an animal model following their exposure to Dzn and the effect on the Brain-Derived Neur...
متن کاملBrain-derived neurotrophic factor:
Dekan Summary BDNF (brain-derived neurotrophic factor) plays an important role in neuronal survival, growth and maintenance of several neuronal systems, serves as neurotransmitter modulator and participates in plasticity important for learning and memory. BDNF is widely expressed in the CNS, beginning early in development and extending throughout life. In the mammalian brain, it is most abundan...
متن کاملDirect binding of polysialic acid to a brain-derived neurotrophic factor depends on the degree of polymerization.
Polysialic acid (polySia) is the homopolymer of sialic acid and negatively regulates neuronal cell-cell and cell-extracellular matrix interactions through steric and repulsive hindrance due to its bulky polyanionic structure. Whether polySia also functions as a positive regulator in the nervous system through binding to specific ligands is not known. In the present study, we demonstrated that a...
متن کاملCholine acetyltransferase from rat brain.
The localization, purification, and some enzymatic properties of choline acetyltransferase from rat brain were studied. Most assays were performed with a specific radiometric micromethod. Solubilization of the enzyme was examined after homogenization of cerebral cortices by means which disintegrate nerve endings. In isotonic KC1 the enzyme was recovered in solution. In more dilute KC1 the enzym...
متن کاملAction of brain-derived neurotrophic factor on function and morphology of visual cortical neurons
Brain-derived neurotrophic factor (BDNF) is known to play a role in experience-dependent plasticity of the developing visual cortex. For example, BDNF acutely enhances long-term potentiation and blocks long-term depression in the visual cortex of young rats. Such acute actions of BDNF suggested to be mediated mainly through presynaptic mechanisms. A chronic application of BDNF to the visual cor...
