Familiarity with gene therapy: new solutions to cure diseases

Introduction:

Gene therapy, as one of the advanced technologies in the field of medicine, has taken an important step in curing diseases and increasing the quality of human life. This method, by using the correction of defective or abnormal genes, provides the possibility of treating genetic diseases and other diseases. Gene therapy is a new treatment method that uses advanced genetic technologies to treat diseases or reduce their symptoms. In this method, a healthy gene is injected or delivered to the cells of the human body to compensate for the function of a defective or inefficient gene. This method can be used in the treatment of genetic diseases such as rare diseases, cancer and chronic diseases such as diabetes and cardiovascular diseases. With the advancement of genetic technology and genetic engineering, we hope that this method will bring a huge improvement in the treatment of various diseases. In this article, we will examine the concept of gene therapy and its new solutions in curing diseases.

The concept of gene therapy:

The concept of gene therapy or gene therapy refers to technologies and methods that use changes in the genome to treat diseases or improve human health. These technologies include techniques such as genome repair, stimulation or silencing of cells that have errors in their genomes, and the use of molecular technologies to modify the genome. The goal of gene therapy is to improve the function of cells, eliminate or reduce the symptoms of diseases, and maintain human health. This technology has attracted the attention of many researchers and industrialists as a new approach and potential capabilities in the field of medicine. Gene therapy techniques are used as a new method in the treatment of diseases. This technology allows to replace dangerous or rarely active genes with healthy genes, because many diseases go back to genetic disorders. Some of the diseases that this method is used to treat include genetic diseases such as hemophilia and leukemia

Some diseases that can be treated using gene therapy include the following:

1. Rare congenital diseases such as blood diseases such as thalassemia and beta-thalassemia.

2. Muscular diseases such as adult motor neuron and muscular dystrophy

3. Rare diseases of the nervous system such as Huntington’s disease.

4. Immune diseases such as autoimmune diseases such as type 1 diabetes

5. Eye diseases such as macular degeneration

6. Liver diseases such as rare diseases such as alpha-antitrypsin mutilation (A1AT) deficiency (A1AD).

7. Lung diseases such as mutilation of alpha-antitrypsin (A1AT) deficiency (A1AD).

8. Heart diseases such as mood potassium channel syndrome (LQTS).

Of course, each disease and each treatment case must be investigated separately, and these cases are only a few examples of diseases that can be treated through gene therapy.

Different methods of gene therapy include:

1. Gene insertion method: This method involves inserting a healthy gene into a diseased cell. This can be done through modified viruses (vector viruses) or non-viral methods such as gold nanoparticles.

2. Gene correction method: In this method, errors in the genome are corrected, including the correction of the copy number of genes, deletion or addition of genetic intervals, and mobile repair of DNA.

3. Gene inhibition: This method involves inhibiting the activity of a specific gene, usually using synthetic RNA that combines with the target gene.

4. Using CRISPR-Cas9: This technology allows us to change and modify genes with high precision. This method is done by cutting and correcting a precise location of the genome.

5. Signal dispersion methods: In this method, biological signals are used to modulate the function of a specific gene.

These techniques are usually chosen based on the type of disease and genetic characteristics of the person.

New solutions to cure diseases include:

1. Development of new and advanced drugs using molecular and genetic technologies.

2. Improving diagnosis and prevention using medical technology such as advanced imaging, genetic tests, and artificial intelligence systems.

4. Promotion of new treatment methods such as cell therapy, combination and targeted drugs.

3. Development and use of new vaccines to control diseases and prevent them.

5. Using wearable technology and portable medical devices to monitor and manage the recovery of diseases.

6. Development of new treatment methods such as multiple combination therapy and gene therapy.

7. Improving health infrastructure and providing health education and disease prevention to different communities.

Success in gene therapy may face scientific and technical challenges and limitations. Some of these restrictions include:

1. Selecting the target gene: Selecting the right gene to treat the disease can be a challenge, because one must choose a gene that completely changes the function of the disease.

2. Gene delivery: One of the biggest challenges in gene therapy is the safe and efficient delivery of genes to the required cells or tissues.

3. Planning and controlling gene expression: To prevent side effects or inappropriate effects, it is necessary to carefully control the expression of the desired gene.

4. Immunity: The body’s immune response to the injection of new genes can cause them to be rejected and cause serious problems for the patient.

5. Permanence and stability of the gene: maintaining the stability of the gene in cells and tissues for a sufficient time to create a therapeutic effect is one of the basic challenges.

Overcoming each of these challenges requires deep research and technical advances in the field of gene therapy.

Conclusion:

Gene therapy has potential as one of the new ways to cure diseases and increase the quality of human life. With the advancement of technology and more studies in this field, we hope that in the near future, patients can benefit from the benefits of this advanced technology and recover. But in order to achieve these goals, it is necessary to pay more attention to the challenges and obstacles in this field. The result of gene therapy may be different and depends on the desired condition and disease. Some positive results can include improvement of the disease state or reduction of symptoms, while in some cases the desired effect may not be achieved or even side effects may occur. In any case, the results of gene therapy require careful examination and analysis by expert doctors.
