Oxidative stress induced-neurodegenerative diseases: the need for antioxidants that penetrate the blood brain barrier

Y Gilgun-Sherki, E Melamed, D Offen - Neuropharmacology, 2001 - Elsevier
Oxidative stress (OS) has been implicated in the pathophysiology of many neurological,
particularly neurodegenerative diseases. OS can cause cellular damage and subsequent cell …

The role of oxidative stress in the pathogenesis of multiple sclerosis: the need for effective antioxidant therapy

Y Gilgun-Sherki, E Melamed, D Offen - Journal of neurology, 2004 - Springer
Accumulating data indicate that oxidative stress (OS) plays a major role in the pathogenesis
of multiple sclerosis (MS). Reactive oxygen species (ROS), leading to OS, generated in …

Antioxidant therapy in acute central nervous system injury: current state

…, Z Rosenbaum, E Melamed, D Offen - Pharmacological …, 2002 - ASPET
Free radicals are highly reactive molecules generated predominantly during cellular respiration
and normal metabolism. Imbalance between cellular production of free radicals and the …

Bax ablation prevents dopaminergic neurodegeneration in the 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine mouse model of Parkinson's disease

…, R Djaldetti, G Liberatore, D Offen… - Proceedings of the …, 2001 - National Acad Sciences
1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) damages dopaminergic neurons in the
substantia nigra pars compacta (SNpc) as seen in Parkinson's disease. Here, we show that …

The “dying-back” phenomenon of motor neurons in ALS

M Dadon-Nachum, E Melamed, D Offen - Journal of Molecular …, 2011 - Springer
Amyotrophic lateral sclerosis (ALS) is a lethal disease, characterized by progressive death
of motor neurons with unknown etiology. Evidence from animal models indicates that …

In Vivo Neuroimaging of Exosomes Using Gold Nanoparticles

…, A Angel, M Motiei, T Sadan, G Yadid, D Offen… - ACS …, 2017 - ACS Publications
Exosomes are emerging as effective therapeutic tools for various pathologies. These
extracellular vesicles can bypass biological barriers, including the blood-brain barrier, and can …

Safety and clinical effects of mesenchymal stem cells secreting neurotrophic factor transplantation in patients with amyotrophic lateral sclerosis: results of phase 1/2 …

…, A Vaknin-Dembinsky, T Ben-Hur, D Offen… - JAMA …, 2016 - jamanetwork.com
Importance Preclinical studies have shown that neurotrophic growth factors (NTFs) extend
the survival of motor neurons in amyotrophic lateral sclerosis (ALS) and that the combined …

Bax ablation protects against myocardial ischemia-reperfusion injury in transgenic mice

E Hochhauser, S Kivity, D Offen… - American Journal …, 2003 - journals.physiology.org
The role of the proapototic Bax gene in ischemia-reperfusion (I/R) injury was studied in three
groups of mice: homozygotic knockout mice lacking the Bax gene (Bax −/− ), heterozygotic …

Intranasal delivery of mesenchymal stem cell derived exosomes loaded with phosphatase and tensin homolog siRNA repairs complete spinal cord injury

…, A Sheinin, I Michaelevski, R Popovtzer, D Offen… - ACS …, 2019 - ACS Publications
Individuals with spinal cord injury (SCI) usually suffer from permanent neurological deficits,
while spontaneous recovery and therapeutic efficacy are limited. Here, we demonstrate that …
