Gene therapy is an innovative method for treating diseases based on altering the patient's genetic information. The main idea is to replace or correct defective genes responsible for the disease, with the aim of restoring normal bodily function. Although the concept of gene therapy began developing in the 1970s, its real achievements became noticeable only in the 1990s, when the first successful clinical trials were conducted.
Initial research in molecular biology and genetic engineering paved the way for the development of gene therapy. In 1972, a unanimous decision by the scientific community recognized the harmful effects of using vectors containing viral DNA to introduce genes into cells. However, this did not stop scientists; they continued to seek safe and effective approaches to use gene therapy in clinical practice.
In 1990, the first clinical trial took place in Washington, involving a girl named Ashley Rosenbaum, who suffered from an infection that hindered the normal functioning of her immune system. The procedure involved introducing a normal version of the damaged gene into the girl's lymphocyte cells. This marked the beginning of a new era in medicine.
There are several approaches to gene therapy, each with its advantages and disadvantages. The most common include:
Gene therapy has several advantages over traditional treatment methods:
The 1990s were a period of active clinical trials that confirmed the effectiveness and safety of several gene therapy methods. In 1999, the first fatality occurred during a clinical trial at Johns Hopkins University. This event led to a significant reassessment of approaches to the invention and application of gene therapy. The scientific community focused on the need for strict ethical standards and oversight in conducting such experiments.
Despite the challenges, gene therapy continued to evolve, and by the end of the 1990s, several methods achieved significant success in treating various diseases, including cystic fibrosis and hemophilia.
With the advancement of gene therapy, not only scientific but also ethical questions arose. How to treat genetic diseases without creating new ones? What is the responsibility of researchers for the outcomes of their work? These questions became subjects of discussion at international conferences and among the scientific community. Some recommendations and international standards were developed to regulate research in this field.
Since gene therapy entered clinical practice, it has evolved and led to the creation of new methods and technologies. One of the most significant developments is the use of CRISPR, a genome editing method that allows scientists to make precise and rapid changes to DNA.
Today, gene therapy is applied not only in the field of hereditary diseases but also for the treatment of cancer, sickle cell anemia, and other conditions, opening new horizons in the fight against serious infections and genetic anomalies.
Gene therapy represents a powerful tool that is changing our perceptions of disease treatment. Despite all the challenges and unresolved questions, the successes achieved open new possibilities for treatment and improving patients' quality of life. The future of gene therapy promises to be bright and promising, and current research may lead to revolutionary changes in the field of medicine.
