The structural alterations of neuronal processes in mice were investigated after the mice were infected with rabies virus (RV). Silver staining of infected brain sections showed severe destruction and disorganization of neuronal processes in mice infected with pathogenic RV but not with attenuated RV. However, neuronal bodies showed very little pathological changes. Electron microscopy revealed...

ABSTRACT Mislocalization of the TAR DNA-binding protein 43 (TDP-43; encoded by TARDBP) from nucleus to cytoplasm is a common feature neurodegenerative conditions such as amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). The downstream in vivo cellular effects this mislocalization are not well understood. To investigate impact mislocalized TDP-43 on neuronal cell ...

The delivery of pulsed electric fields to biological cells for regenerative research and therapeutic applications is a field that has been widely explored. Picosecond have shown induce intracellular effects directly target cell membrane proteins as well being able permeabilization death by apoptosis. Additionally, ultrashort pulses can be focused delivered in noncontact manner possible targetin...

Abstract Background DHA‐H (2‐hydroxy‐docosahexaenoic acid) is a promising therapeutic approach for Alzheimer’s Disease (AD). gives rise to dose‐dependent increased levels of HPA (Heneicosapentaenoic in blood plasma and brain whereas remains virtually absent from the DHA‐H‐treated mice. Oral administration transgenic model AD (5xFAD mice) induces significative cognitive recovery. However, molecu...

Axon degeneration is observed at the early stages of many neurodegenerative conditions and this often leads to subsequent neuronal loss. We previously showed that inactivating the c-Jun N-terminal kinase (JNK) pathway leads to axon degeneration in Drosophila mushroom body (MB) neurons. To understand this process, we screened candidate suppressor genes and found that the Wallerian degeneration s...

AIMS This is a review of preclinical studies covering alcohol-induced brain neuronal death and loss of neurogenesis as well as abstinence-induced brain cell genesis, e.g. brain regeneration. Efforts are made to relate preclinical studies to human studies. METHODS The studies described are preclinical rat experiments using a 4-day binge ethanol treatment known to induce physical dependence to ...

Glutamate excitotoxicity causes neuronal dysfunction and degeneration. It is implicated in chronic disorders, including Alzheimer's disease, and in acute CNS insults such as ischemia. These disorders share prominent morphological features, including axon degeneration and cell body death. However, the molecular mechanism underlying excitotoxicity-induced neurodegeneration remains poorly understo...

Background and Objective: Temporal lobe epilepsy is hallmarked with neuronal degeneration in some areas of hippocampus and mossy fiber sprouting in dentate area. Considering some evidences on neuroprotective and antioxidant activity of silymarin (SM), this study was undertaken to evaluate the preventive effect of this agent on structural changes in hippocampus of kainate-epileptic rats. Materia...

Introduction: A large body of experimental evidence supports a role for oxidative stress as a mediator of nerve cell death in Parkinson's disease (PD). Flavonoids like quercetin have been reported to prevent neuronal degeneration caused by increased oxidative burden, therefore, this study examined whether quercetin administration at a high dose would attenuate behavioral abnormalities in e...
