But the overwhelming amount of gene therapy, both in basic and clinical research, is not in germlines, but the somatic cells that comprise body tissues other than those that produce new people. Gene therapy is an experimental form of treatment it works by replacing a faulty disease-causing gene with a working version, or by introducing a new gene to cure a condition or modify its effects the aim is to eliminate genetic diseases at their source the challenge for nations experimenting. A major challenge with gene therapy is delivery how do we get the therapeutic gene into different tissues you kind of explore the basic biology to figure out where does nature want us to go. Since the introduction of the gene therapy concept in the early 90s, research has entered a fast evolving era achievement of efficient and long-term gene transfer to the target cells with minimal host immune responses and toxicity remains one of the major challenges to gene therapists.
Albeit viral designs and manufacturing have become sophisticated with time, yet efficiency, toxicity, time and cost remain a mega challenge recent gene therapy drugs cost a fortune, between $06 million to $12 million, the major cost contributor being viral manufacturing and gene delivery into the cells. In its purest form, gene therapy is the delivery and expression of a correct copy of a gene into cells in which the endogenous gene is non-functional it can lead to cure — or significant enhancement of the quality of life — of the patient. The exciting renaissance in cell and gene therapy over the past five years has yielded some of the most innovative medical advances in the industry's pipeline today. In gene therapy, a gene is spliced into a vector, which delivers the gene into living cells gene therapy for cancer carries a dual challenge: designing a vector that efficiently targets cancer cells and designing a gene that consistently cures or kills the transformed cell. Types of gene therapy however, these cells can be divided into two major categories: somatic cells (most cells of the body) or cells of the germline (eggs or sperm) in theory it is possible to transform either somatic cells or germ cells.
