multiple sclerosis (ms) causes loss of the myelin sheath, which leads to loss of neurons. regeneration of myelin sheath stimulates axon regeneration and neurons’ survival. in this study, olfactory ensheathing cell (oec) transplantation is investigated to restore myelin sheath in an experimental model of ms in male mice.oecs were isolated from the olfactory mucosa of seven-day-old infant rats an...

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) characterized by inflammatory and neurodegenerative processes. One of its pathophysiological hallmarks is demyelination, a consequence of oligodendroglial cell death leading supply shortfall and missing electrical insulation to axons. Demyelination induced consequences on neuronal network activity and subsequen...

Demyelination is the pathologic hallmark of the human immune-mediated neurologic disease multiple sclerosis, which may be triggered or exacerbated by viral infections. Several experimental animal models have been developed to study the mechanism of virus-induced demyelination, including coronavirus mouse hepatitis virus (MHV) infection in mice. The envelope spike (S) glycoprotein of MHV contain...

central nervous system axons fail to regenerate after spinal cord injury (sci), partially due to the accumulation of extracellular matrix molecules in the lesion and formation of the glial scar. depakine, as known as histone deacetylase inhibitor, has neuroprotective effects. this study evaluated the histological changes (cavitation and axon regeneration) after sci associated with (following ad...

Previous case reports have demonstrated COVID-19 related neurotropism. Neural infection may result from trans-lamina cribrosa invasion that allows to reach the brain through olfactory tract. A wide range of symptoms headaches, anosmia, dysgeusia neuropathy, encephalitis, cerebrovascular stroke, and rarely demyelination has been reported. Here, we report a pontine causing generalized weakness as...

introduction: demyelination is one of the main causes of neurological disability. it is the end product of numerous pathological processes, multiple sclerosis (ms) being the most common cause. more than 70% of the ms patients suffer from optic disturbances. this disease commonly affects the optic pathway, particularly the optic nerves and chiasm. several attempts have been made to produce a sui...
