Human acquired immunodeficiency virus (HIV) is a nightmare in the medical world. Since the disease has expanded for decades, it has not found a way to completely cure patients. It is only possible to use cocktail therapy or antiretroviral drugs. Therapy) slows down the onset of the disease and thereby prolongs the life of the patient. Recently, a research team successfully used genetic editing technology to remove HIV-1 DNA from human immune cells and prevent further replication and reinfection of the virus.
The research team from Temple University in the United States uses the CRISPR/Cas9 gene editing technology to remove the HIV-1 virus from the T cells that play an important role in the human immune response, leaving it no longer able to infect other health. cell. The so-called CRISPR/Cas9 technology is the use of guide RNA to change the target site in the cellular DNA.
Earlier, the team had successfully removed HIV-1 DNA from human immune cells. The most recent study showed that the cleared cells would not be infected with HIV. Dr. Kamel Khalili, a member of the research team, said that antiretroviral drugs can help patients control HIV infection, but as long as the patient forgets or stops taking the drug, the virus will start to replicate on its own, causing the disease to deteriorate again. .
Khalili believes that this discovery is very important for the development of different stages. “This completely demonstrates that we are effective in removing the HIV virus from the helper T cells with CD4 receptors, and that this mutation can also be made by the mutations that bring the virus genome,†he said. The virus is no longer replicated. In addition, it also means that this technology can protect other cells from infection, and this technology is not only safe, but also does not cause any toxic effects."
Although the current successful case is only to experiment on the removal of T cells from AIDS patients, and has not yet conducted a real human trial, Khalili believes that this technology is dealing with very important issues in the medical field. The results of the experiment are also quite successful, and they should continue to develop in the direction of human experiments.
