Question

uses and types of gene therapy.........

Answer 1

Therapy

Although still in the early stages, gene therapy is a technique that treats or prevents disease through the use of genes. There is still a long way to go until it leads to consistently successful and widely used methods, but it's a very promising area of medical research.

DNA contains the genes that are modified as part of gene therapy.

There are three basic approaches to gene therapy:

Replacing a gene that causes a medical problem with one that doesn'tDeactivating problem genesAdding new genes to the human body to help it fight disease

Gene therapy can be used on the two types of cells in the human body--somatic cells, which account for most cell types, or germline cells, which are reproductive cells. With somatic cell gene therapy, only the person whose cells were altered will be affected. With germline cell gene therapy, the genetic alterations will be passed down to an individual's children. Currently, somatic cell therapy is considered much safer and is the only type being tested for use in humans.

Gene therapies have to be introduced into the body by one way or another. The most common method is through the use ofvectors, which are basically transporters that deliver the therapeutic gene to the problem cell. Vectors are commonly viral, like DNA and RNA viruses, but can be non-viral, like liposomes (fat molecules that can carry DNA) or plasmid DNA (small DNA molecules in cells), and they can be administered in two main ways:

With ex vivo somatic gene therapy, the target cell is taken out of the body, cultured in a lab with the vector, and then put back into the body.With in situ somatic gene therapy, the vector is introduced right into the problem tissue.


Uses of Gene Therapy

Uses of gene therapy can be split into current uses and potential uses being researched.

There are currently only a handful of examples of gene therapy in use today. One is a Chinese gene therapy that is used in the treatment of some cancers. Another is a gene therapy drug registered in Russia to treat peripheral artery disease. In 2012, there was also a gene therapy treatment approved in Europe for a rare inherited disorder called lipoprotein lipase (LPL) deficiency. However, this treatment costs around $1 million and is, therefore, currently the most expensive medicine in the world.

There are also many potential uses for the future, some more positive than others. Athletes could eventually try to use gene therapy to improve their performance. Gene therapy could also improve or modify people's appearances, metabolisms, and intelligence. It could also be used to reduce our susceptibility to diseases at birth. In general though, any disease or medical problem that has a genetic element could be reduced or prevented using gene therapy in the future.

The potential for gene therapies in the future is controversial. The idea of modifying people, whether at birth or afterwards, is often compared to playing God. The idea that people could modify their children without their consent is easier for people to justify when talking about diseases, but not so much when considering intelligence

Answer 2

hey user here is yr answer!!

There are two different types of gene therapy depending on which type of cell are treated : Somatic gene therapy transfer of a section of DNA. to any cell of the body
and germline gene therapy.

●gene therapy is designed to introduce genetic material into cell to companset for abnormal genes or to make a beneficial protein.

hope it helps!
keep asking.☺☺
