How Does Gene Therapy Work?

Gene therapy is a new way to treat diseases by changing the genes in cells. We use special methods and tools to get the genetic material into cells. This can help fix genetic problems.

Delivery Methods and Vectors

Gene therapy uses vectors to carry genetic material into cells. Vectors are vehicles that carry the genetic material into the cells, and they can be viral or non-viral. Viral vectors are often used because they work well. But, non-viral vectors are being looked at for their safety benefits.

The right vector depends on the treatment and the cells it targets. For example, adeno-associated viruses (AAVs) are good because they can get into many cells and don’t usually cause an immune reaction.

The Treatment Process for Patients

The treatment for gene therapy has several steps. First, patients get diagnosis and screening to see if they can get the therapy. Then, they get pre-treatment preparation, like medicines to calm the immune system.

When it’s time for the treatment, the gene therapy is given to the patient. After, they need follow-up care to check how well the treatment worked and handle any side effects.
