Herpes Virus Amplicon Vectors

Herpes Virus Amplicon Vectors

Since its emergence onto the gene therapy scene nearly 25 years ago, the replication-defective Herpes Simplex Virus Type-1 (HSV-1) amplicon has gained significance as a versatile gene transfer platform due to its extensive transgene capacity, widespread cellular tropism, minimal immunogenicity, and its amenability to genetic manipulation. Herein, we detail the recent advances made with respect ...

Use of herpes virus amplicon vectors to study brain disorders.

There is an enormous initiative to establish the genetic basis for disorders of brain function. Unfortunately, genetic intervention is not accomplished easily in the nervous system. One strategy is to engineer and deliver to neurons specialized viral vectors that carry a gene (or genes) of interest, thereby exploiting the natural ability of viruses to insert genetic material into cells. When de...

Silencing by Forming Inactive Chromatin Amplicon Vectors Cause Rapid Transgene Conventional Herpes Simplex Virus

Silencing Status Epilepticus-Induced BDNF Expression with Herpes Simplex Virus Type-1 Based Amplicon Vectors

Brain-derived neurotrophic factor (BDNF) has been found to produce pro- but also anti-epileptic effects. Thus, its validity as a therapeutic target must be verified using advanced tools designed to block or to enhance its signal. The aim of this study was to develop tools to silence the BDNF signal. We generated Herpes simplex virus type 1 (HSV-1) derived amplicon vectors, i.e. viral particles ...

Eradication of pre-established lymphoma using herpes simplex virus amplicon vectors.

Herpes simplex virus amplicon vectors expressing RANTES (HSVrantes) and the T-cell costimulatory ligand B7.1 (HSVB7.1) were studied for their ability to elicit a tumor-specific T-cell response in a murine lymphoma model. HSVB7.1- and HSVrantes-transduced EL4 cells expressed high levels of B7.1 and RANTES as analyzed by flow cytometry and enzyme-linked immunosorbent assay, respectively. Inoculat...
