We tested whether transfer of the gene coding for glutamic acid decarboxylase to dorsal root ganglion using a herpes simplex virus vector to achieve release of GABA in dorsal horn would attenuate nociception in this condition. Subcutaneous inoculation of a replication-defective herpes simplex virus vector expressing glutamic acid decarboxylase (vector(More)
Neuropathic pain after spinal cord injury (SCI) represents a difficult problem that is commonly refractory to conventional medical management. To determine if spinal release of gamma-amino butyric acid (GABA) could reduce below-level central neuropathic pain after SCI, we constructed a replication-incompetent herpes simplex virus (HSV)-based vector encoding(More)
Neuropathic pain is a difficult clinical problem that is often refractory to medical management. Glial-derived neurotrophic factor (GDNF) administered intrathecally has been shown to prevent or reduce pain in an animal model of neuropathic pain, but cannot be delivered in the required doses to treat human pain. We have previously demonstrated that(More)
Previous studies have demonstrated that either the neurotrophin glial-derived neurotrophic factor (GDNF) or the antiapoptotic peptide Bcl-2 delivered into striatum by a viral vector protects dopaminergic neurons of the substantia nigra in vivo from degeneration induced by the administration of the neurotoxin 6-hydroxydopamine (6-OHDA). In this study we used(More)
Factors that enhance the intrinsic growth potential of adult neurons are key players in the successful repair and regeneration of neurons following injury. Injury-induced activation of transcription factors has a central role in this process because they regulate expression of regeneration-associated genes. Sox11 is a developmentally expressed transcription(More)
Proximal spinal nerve injury results in the death of motor neurons in ventral horn. We have previously demonstrated this cell death can be prevented by HSV-mediated transfer of the gene coding for the antiapoptotic peptide Bcl-2 7 days prior to injury, but that expression of Bcl-2 does not preserve ChAT expression in the lesioned cells. In the current(More)
Neurotrophic factors have been demonstrated to prevent the development of peripheral neuropathy in animal models, but the therapeutic use of these factors in human disease has been limited by the short serum half-life and dose-limiting side effects of these potent peptides. We used peripheral subcutaneous inoculation with a replication-incompetent, genomic(More)
Attempts to develop clinical treatments for neuropathy using neurotrophins have not been successful. We tested whether neurotrophin gene delivery to dorsal root ganglia (DRGs) using non-replicating herpes simplex virus (HSV)-based vectors could prevent the development of neuropathy caused by administration of cisplatin. Following subcutaneous inoculation of(More)
In order to test the functional implication of herpes simplex virus (HSV) vector-mediated gene transfer after axonal injury, we injected replication-incompetent HSV vectors coding for the anti-apoptotic peptide Bcl-2 and the glial cell-derived neurotrophic factor (GDNF), separately or in combination into ventral spinal cord 30 min after a crush injury to(More)
