Gene therapy is a revolutionary medical treatment.

Gene therapy is a cutting-edge medical approach that involves manipulating DNA to treat and prevent diseases.

It has the potential to cure genetic disorders.

Gene therapy offers a promising solution to inherited genetic disorders by introducing functional genes into a patient’s cells.

It can be used to target cancer cells.

Gene therapy has shown potential in fighting cancer by delivering therapeutic genes directly to tumor cells and inhibiting their growth.

The first approved gene therapy treatment was in 2017.

In 2017, the United States Food and Drug Administration (FDA) approved the first gene therapy treatment for a specific form of leukemia.

Gene therapy can be delivered using viral vectors.

Viruses can be modified to carry therapeutic genes and deliver them into targeted cells, acting as vectors in gene therapy.

Non-viral vectors are also used in gene therapy.

Besides viral vectors, non-viral methods such as liposomes and nanoparticles are being explored for gene delivery.

Gene therapy can be performed ex vivo or in vivo.

In ex vivo gene therapy, the patient’s cells are modified outside the body and then reintroduced, while in in vivo gene therapy, the genes are directly introduced into the body.
