Gene therapy is the insertion of a gene into an individual's cells to prevent or treat serious diseases. The inserted gene may be a healthy copy of a mutated gene, or it may be a different gene that counteracts the effects of a faulty gene.
Genes can be delivered in vivo, directly into a person, or ex vivo, into cells removed from the body, which are then transplanted back.The new gene is inserted using a vector, typically a modified virus that can enter a cell and deliver the DNA to the nucleus.
Some vectors integrate the DNA into the genome, while others remain outside the chromosome. The vectors contain a promoter region so that the gene can be transcribed. The introduced gene is then translated into protein providing a treatment for the disease.
유전자 치료(gene therapy)는 심각한 질병을 예방하거나 치료하기 위해 사람의 세포에 유전자를 삽입하는 기술입니다. 추가된 유전자는 환자에게서 변이된 유전자의 건강한 버전일 수도 있고, 환자의 질병을 유발하는 유전자를 비활성화하거나 보상하는 다른 유전자일 수도…
