A Potential Cure for AIDS: Defeating HIV With a Single Injection

Disintegrating Virus Cell Destroy COVID Concept

The injection causes type B white blood cells to be genetically engineered inside the patient’s body that would generate neutralizing antibodies against the HIV virus.

A new technology offers treatment for HIV infection through a single injection and also has the potential to be developed into a cure for AIDS.

Tel Aviv University researchers have developed a breakthrough AIDS treatment using genetic engineering and CRISPR technology. By modifying white blood cells within the patient’s body, the treatment prompts the release of anti-HIV antibodies upon viral encounter. The study’s findings offer potential for a vaccine or one-time therapy that evolves within the body to combat viruses.

A new study from Tel Aviv University proposes a novel AIDS treatment that could be turned into a vaccine or a one-time treatment for HIV patients. The research explored modifying type B white blood cells in the patient’s body to release anti-HIV antibodies in response to the virus. Dr. Adi Barzel and Ph.D. student Alessio Nehmad led the study, which was conducted in partnership with the Sourasky Medical Center (Ichilov), the George S. Wise department of life sciences, and the Dotan Center for Advanced Therapies. The study was carried out in cooperation with other researchers from Israel and the United States. The findings were published recently in the renowned journal Nature Biotechnology.

Many AIDS patients’ lives have improved during the past two decades as a result of the administration of medicines that have transformed the condition from fatal to chronic. However, we have a long way to go before finding a medication that can offer patients a permanent cure. Dr. Barzel’s laboratory pioneered one feasible method, a one-time injection. His team devised a technology that employs type B white blood cells that are genetically altered within the patient’s body to release neutralizing antibodies against the HIV virus, which causes the disease.

B cells are white blood cells that produce antibodies against viruses, bacteria, and other pathogens. Bone marrow is where B cells are formed. When they mature, B cells move into the blood and lymphatic system and from there to the different body parts.

Dr. Barzel explains: “Until now, only a few scientists, and we among them, had been able to engineer B cells outside of the body, and in this study, we were the first to do this in the body and to make these cells generate desired antibodies. The genetic engineering is done with viral carriers derived from viruses that were engineered so as not to cause damage but only to bring the gene coding for the antibody into the B cells in the body. Additionally, in this case, we have been able to accurately introduce the antibodies into a desired site in the B cell genome. All model animals who had been administered the treatment responded and had high quantities of the desired antibody in their blood. We produced the antibody from the blood and made sure it was actually effective in neutralizing the HIV virus in the lab dish.”

The genetic editing was done with CRISPR. This is a technology based on a bacterial immune system against viruses. The bacteria use the CRISPR systems as a sort of molecular “search engine” to locate viral sequences and cut them in order to disable them. Two biochemists who had figured out the sophisticated defense mechanism, Emmanuelle Charpentier and Jennifer Doudna, were able to reroute for the cleavage of any DNA of choice. The technology has since been used to either disable unwanted genes or repair and insert desired genes. Doudna and Charpentier earned international recognition when they became chemistry Nobel Prize winners in 2020.

Ph.D. student Alessio Nehmad elaborated on the use of CRISPR: “We incorporate the capability of a CRISPR to direct the introduction of genes into desired sites along with the capabilities of viral carriers to bring desired genes to desired cells. Thus, we are able to engineer the B cells inside the patient’s body. We use two viral carriers of the AAV family, one carrier codes for the desired antibody, and the second carrier codes the CRISPR system. When the CRISPR cuts in the desired site in the genome of the B cells it directs the introduction of the desired gene: the gene coding for the antibody against the HIV virus, which causes AIDS.”

Currently, the researchers explain, there is no genetic treatment for AIDS, so the research opportunities are vast. Dr. Barzel concludes: “We developed an innovative treatment that may defeat the virus with a one-time injection, with the potential of bringing about tremendous improvement in the patients’ condition. When the engineered B cells encounter the virus, the virus stimulates and encourages them to divide, so we are utilizing the very cause of the disease to combat it. Furthermore, if the virus changes, the B cells will also change accordingly in order to combat it, so we have created the first medication ever that can evolve in the body and defeat viruses in the ‘arms race’.”

He continues, “Based on this study we can expect that over the coming years we will be able to produce in this way a medication for AIDS, for additional infectious diseases and for certain types of cancer caused by a virus, such as cervical cancer, head, and neck cancer and more.”

  1. Dear Docs
    This is very encouraging. People have been wondering how faster the COVID 19 vaccines were worked in rather HIV. HIV is the one which should have the injections before anything because it has mentally and psychological affects.

    Kindly when will this injection be available in for example Kenya ,Nairobi.

      Good development but how soon will the technology be available for public consumption?

      • Yes! I really wish this technology should be available for humans and this should turn out to be a sterilizing cure. As its extremely difficult for people to live with this virus.

      Wonderful what a success in the making the team has really tried,God bless you Sir/MA’s.Humanity will never forget you guys

  9. HIV is a hoax just like COVID 19 because it never was isolated as a ‘virus’it claimed to be

    However, AIDS is real and it’s caused by bad drugs and malnutrition not virus

    The idea of hiv being a virus is the work of big pharma to enrich their pockets and sell drugs and to control people through panucs

  10. Great Job. The world can wait especially Africa, we hope the drug or vicine does gets to Africa

  11. Dear Doc, thanks for the good work. God grant you more wisdom to heal His people. I hope it will be approved by all and given all infected in all continents and countries.

  12. We have suffered enough..I hope for the best and I pray there will be a cure one day.

  13. Thank you guys
    We are praying to God to help you

  27. please when is it going to be ready also in Ghana west Africa

  28. I cant wait for these vaccine

  29. Dear Dr may God give u more wisdom and knowledge to make such HIV one time vaccine to cure helpless people .I wish that u can accomplish this vaccine and become a hope for millions may God bless u Dr

  30. Please be fast about it almighty God will help you

  31. Best wishes,may your hard work bring smile on infected persons

  32. May God bless you, for how long will it be available for the suffering people to tske

  33. It’s funny how all these long studies, experiments and trials are all paid for by governments through grants which are paid for through public paying taxes yet whenever the trials are done and the drugs become available, they end up costing an arm and a leg or too expensive to afford. I believe that it’s nice to make a profit on things but to also have ethical mind set and put lives before money! Also I think that if a company that can make a cure for a disease would say hey, we will provide the whole world with a cure for this and instead of charging an arm and a leg, we will ask everyone in the world for donations starting at $1.00 , well I believe that most people in the world would love to get rid of all diseases in the world! And even if everyone in the world only donated just $1.00 which I’m sure that people would donate much more because it’s for a good cause, well the manufacturer, and or pharmaceutical companies would make so much more money than if they charged an arm and a leg and everyone would have life saving drugs or cures while they are still making alot of money through volume rather than being greedy and letting people suffer and die!

  34. When we expect this treatment in clinics ?

  35. I have allot of spiritual goods at my store that you can benefit from, I don’t know if you will love to see those spiritual goods that am talking about, if yes please reply back to me so that I can show you the spiritual goods at my store okay…

  36. Hello when will this injection be available in hospital
