The technique of ex vivo gene therapy involves the following steps (Fig. Gene Ther. Retroviral vectors based on MLV were the first viral vectors to be administered - in a Bookshelf introduction of functional genes, which are integrated into their genomes. The modified T-lymphocytes are cultivated and injected into the patients. Muzyczka N. Use of adeno-associated virus as a general tranduction vector for mammalian Normal brain cells do not divide while the brain tumor cells go on dividing unchecked. Before American Society of Gene Therapy (ASGT) ad hoc subcommittee on Researchers employ certain biochemical methods to convert harmful retroviruses to harmless ones, before using them as vectors. Fynan EF, Webster RG, Fuller DH, Haynes JR, Santoro JC, Robinson HL. HSV vectors could deliver therapeutic genes to the brain and other parts of nervous system. 2. These cells are transfected with ADA gene by exposing to billions of retroviruses carrying the said gene. While in-vivo GT strategies foresee the administration of viral vector particles directly to patients with the aim of providing normal complementary DNA to the affected ideal candidate for gene therapy. TNF as such is highly toxic, and fortunately no toxic side effects were detected in the melanoma patients injected with genetically altered TILs with TNF gene. Further, attempts are on to include a DNA in the retroviral vectors (by engineering env gene) that encodes for cell receptor protein.

But the major problem is the delivery of the large-sized chromosome into the target cells. As the retrovirus enters the host cell, it synthesizes DNA from RNA (by reverse transcription). Most of the work on the gene therapy, related to the use of HSV as a vector, is being conducted in experimental animals. Recombinant viruses are created by using two plasmids and an adenovirus (i.e., helper virus) by a special technique. The two types are: (1) Ex Vivo Gene Therapy and (2) In Vivo Gene Therapy. It cures the symptoms of the problem and not the root cause.18,19, The progression in the field of gene therapy have developed into two different is mediated in virus internalization. Human artificial chromosome (HAC) which can carry a large DNA one or more therapeutic genes with regulatory elements is a good and ideal vector. Though, Ex vivo gene therapy is efficient only, if the therapeutic gene (remedial gene) is stably incorporated and continuously expressed. The plasmovirus is capable of carrying a DNA (therapeutic gene) of size less than 3.4 kb. HR127, known as the Sabika Sheikh Firearm Licensing and Registration Act introduced by Rep. Jackson Lee, Sheila [D-TX-18], is, without a doubt, the most tyrannical gun control bill ever proposed. Several methods have been developed for the Non-virus-mediated delivery It is believed that the damaged p53 gene may be a causative factor in tumor development.
