Lentiviral vectors: turning a deadly foe into a therapeutic agent

Abstract

The past 3 years have witnessed the spectacular irruption of lentiviral vectors into the limelight of the gene therapy scene. Owing to their ability to deliver transgenes in tissues that had long appeared irremediably refractory to stable genetic manipulation, lentivectors have opened fresh perspectives for the genetic treatment of a wide array of hereditary as well as acquired disorders, and a concrete proposal for their clinical use seems imminent. This article traces the path that has led to this rapid development and describes the current state of the art in the design and production of lentiviral vectors. The important question of biosafety is discussed. This system seems to have the edge over other gene delivery tools for particular targets, however, there remain several issues to be resolved before lentivectors make it to the bedside. Gene Therapy (2000) 7, 20-23.

Gene therapy

Gene therapy is a medical technology which aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells. The first attempt at modifying human DNA was performed in 1980, by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990.

Gene delivery

Gene delivery is the process of introducing foreign genetic material, such as DNA or RNA, into host cells. Gene delivery must reach the genome of the host cell to induce gene expression. Successful gene delivery requires the foreign gene delivery to remain stable within the host cell and can either integrate into the genome or replicate independently of it. This requires foreign DNA to be synthesized as part of a vector, which is designed to enter the desired host cell and deliver the transgene to that cell's genome.

Gene gun

In genetic engineering, a gene gun or biolistic particle delivery system is a device used to deliver exogenous DNA (transgenes), RNA, or protein to cells. By coating particles of a heavy metal with a gene of interest and firing these micro-projectiles into cells using mechanical force, an integration of desired genetic information can be introduced into desired cells. The technique involved with such micro-projectile delivery of DNA is often referred to as biolistics, short for "biological ballistics".
