Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...

BACKGROUND Two ongoing phase II clinical trials (RENEW and SYNERGY) have been developed to test the efficacy of anti-LINGO-1 antibodies in acute optic neuritis and relapsing forms of multiple sclerosis, respectively. Across a range of experimental models, LINGO-1 has been found to inhibit neuron and oligodendrocyte survival, axon regeneration, and (re)myelination. The therapeutic effects of ant...

Detailed Transverse relaxation time (T2) MRI imaging studies of a rat optic nerve model were performed in order to elucidate the effect of axonal regeneration in an optic nerve after traumatic injury. After rats were subjected to left optic nerve crush, a Carr-Purcell-Meiboom-Gill (CPMG) imaging sequence was used to acquire T2 relaxation decay curves from both the crushed left optic nerve (LOP)...

OBJECTIVES/HYPOTHESIS Functional recovery after a recurrent laryngeal nerve or facial nerve injury may be impaired due to aberrant reinnervation. Previous work in a rat peripheral nerve injury model found vincristine to be a potent inhibitor of reinnervation, and it has since been used to effectively block neural regeneration in other animal models. However, vincristine's narrow therapeutic ind...

OBJECTIVE To investigate the influence of low intensity laser irradiation on the regeneration of the fibular nerve of rats after crush injury. METHODS Twenty-five rats were used, divided into three groups: 1) intact nerve, no treatment; 2) crushed nerve, no treatment; 3) crush injury, laser irradiation applied on the medullary region corresponding to the roots of the sciatic nerve and subsequ...

After nerve injury, adult sensory neurons can regenerate peripheral axons and reconnect with their target tissue. Initiation of outgrowth, as well as elongation of neurites over long distances, depends on the signaling of receptors for neurotrophic growth factors. Here, we investigated the importance of gp130, the signaling subunit of neuropoietic cytokine receptors in peripheral nerve regenera...

OBJECTIVES To develop a mouse model for measuring facial nerve injury and recovery and to test the hypothesis that overexpression of the antiapoptotic gene, bcl2, enhances recovery of facial nerve function after peripheral crush injury. DESIGN Prospective analysis of recovery of function after facial nerve crush injury in mice at juvenile (postnatal day 7) and adult (postnatal day 30) ages wi...

The expression and content of calcitonin gene-related peptide (CGRP) and secretogranin II (SgII) in adult rat motor neurons were examined by in situ hybridization, Northern blot analysis, and immunocytochemistry. Normal motor nerve terminals did not contain detectable CGRP or SgII. Ten to 15 days after a peripheral nerve crush about 80% of the motor nerve terminals reinnervating the soleus (SOL...

PURPOSE To characterize the histological changes that occur in response to induction of ischemic or mechanical optic nerve damage in transgenic mice. METHODS Either optic nerve crush injury or rodent anterior ischemic optic neuropathy (rAION) were induced in the right eye of mice transgenic for the Thy1 gene promoter expressing cyan fluorescent protein (CFP; n=40) and mice transgenic for the ...
