Development And Optimization Of Herpes Simplex Virus Vectors For Multiple Long-Term Gene Delivery To The Peripheral Nervous System

Development and Optimization of Herpes Simplex Virus Vectors for Multiple Long-Term Gene Delivery to the Peripheral Nervous System. Herpes simplex virus (HSV) has often been suggested as a suitable vector for gene delivery to the peripheral nervous system as it naturally infects sensory nerve terminals before retrograde transport to the cell body in the spinal ganglia where latency. Several RNA viruses have also been developed for gene delivery, including a poliovirus replicon system for motor neurons. Herpes simplex virus (HSV) is an attractive candidate for use as a viral vector to express foreign genes. There has been some success on that front in peripheral neurons; however, long-term expression in the central nervous system has not been as good.

Development and Optimization of Herpes Simplex Virus Vectors for Multiple Long-Term Gene Delivery to the Peripheral Nervous System 2Virus vectors for gene delivery to the nervous system on ResearchGate, the professional network for scientists. Many developments in vectors should be occurring over the next few years that should increase the potential of these vectors for therapeutic gene delivery. Development and Optimization of Herpes Simplex Virus Vectors for Multiple Long-Term Gene Delivery to the Peripheral Nervous System. A number of studies have demonstrated transduction of DRG neurons using herpes simplex virus, adenovirus and more recently, adeno-associated virus (AAV). 6 as a gene transfer tool to target cellular mechanisms involved in the generation and development of chronic pain in mice. Palmer JA, Branston RH, Lilley CE, Robinson MJ, Groutsi F, Smith J, Latchman DS, Coffin RS: Development and optimization of herpes simplex virus vectors for multiple long-term gene delivery to the peripheral nervous system. Reduced immune responses after vaccination with a recombinant herpes simplex virus type 1 vector in the presence of antiviral immunity. 4e F4 ), the differentially pre-infected mice were only able to develop weak CTL responses KOS, 5; HSV-F, 55; T0-GFP, 13 (Fig. Development and optimization of herpes simplex virus vectors for multiple long-term gene delivery to the peripheral nervous system.

Our results support the utility of HSV vectors for gene silencing in peripheral neurons and the potential application of this technology to the study of nociceptive processes and in pain gene target validation studies. Lentiviruses, adenoassociated viruses and more recently, herpes simplex virus have been engineered to deliver short-hairpin RNA (shRNA) to parts of the nervous system (15 20,21). Development and optimization of herpes simplex virus vectors for multiple long-term gene delivery to the peripheral nervous system. Several issues must be considered in choosing a gene transfer vector for a spe- cific application. Figure 1 HSV vector-mediated gene delivery to the nervous system can be accom-. This paper reviews the major HSV-1 vector systems and analyses the common elements which These properties have yet to be determined for different viral vectors for human applications and gene delivery to different tissues by different methods of administration in animal models will need to be explored to translate this to clinical trials.

Virus Vectors For Gene Delivery To The Nervous System

Adeno-associated virus (AAV)-mediated gene delivery has emerged as an effective and safe tool for both preclinical and clinical studies of neurological disorders. Adeno-associated virus is a non-pathogenic dependovirus from the parvoviridae family requiring helper functions from other viruses, such as adenovirus or herpes simplex virus, to fulfill its life cycle (Dayton et al. To overcome these limitations, several methods have been developed to improve brain transduction after systemic injection (Figure 1). Samples were washed four times (10 min each) and developed with diaminobenzidine (Sigma, St. Louis, MO).
