It's the first time that the approach which led to the eradication of HIV in Berlin patient Timothy Brown nine years ago has been reproduced clinically, according to lead study author Professor Ravindra Kumar Gupta of the University of Cambridge. Such remnants were also found in Brown's case. The Times explained that HIV uses protein to enter certain immune cells but can not adhere to the mutated version. Doctors theorize that whatever HIV was left hiding in their systems after the treatment wilted away because it had nowhere left to spread.

"It's quite hard to imagine that all trace of a virus that infects billions of cells was eliminated from the body".

Below, we speak to Manon Ragonnet-Cronin, a specialist in HIV at Imperial College London, who works in collaboration with the UK HIV Drug Resistance Database, to explain the treatment further.

Zerbato disclosed support from the Melbourne HIV Cure Consortium. After five years of grueling treatment, he underwent a bone marrow transplant in May 2016.

Many other data, such as the sharp decline in the number of HIV-specific antibodies, indicated that the virus had disappeared from the patient's body, the researchers write. The patient will receive high doses of chemotherapy before the operation. "To scale that up to other patients would be hard". Bone-marrow donors in both cases did not carry the rare CCR5 gene, which is the gene that serves as a protection against HIV. Unlike the Berlin patient, he didn't require full-body irradiation or a second round of stem cell transplantation.

While most HIV patients can manage the virus with current treatment options and have the possibility of living a long and healthy life, experimental research of this kind can provide insight into how a more widely applicable cure might be developed in the future.

Despite the effort being put into the fight against the human immunodeficiency viruses (HIV), only one person has ever been declared functionally cured. "I've been waiting for company for a long time". "When the Berlin patient had the therapy, his chances of dying just from removing his immune system was between 25 and 50 per cent".

But they added there needs to be "more than a handful of patients" cured of HIV to understand the duration of follow-up needed and the "likelihood of an unexpected late rebound in virus replication". Researchers continue to follow this third patient. Seventeen months after the transplant, Castillejo's doctors announced to the world that he had been cured of both cancer and HIV. However, he received stem cells from donors with a genetic mutation that is present in less than one percent of Europeans. "Since we now have a pretty good sense that this mutation might be very important, then we have a very good idea that could be a very fruitful way forward".

It is fundamentally not possible to cure AIDS to this day. "I don't want people to think: & # 39; Oh, you & # 39; were selected".

Brown's donor also had the delta 32 mutation, making them resistant to HIV. Miraculously, his body had shown no active infection. "It might actually make these guys, now that they have immune systems that don't have the CCR5 vulnerability, it might actually nearly eliminate the possibility they would ever be HIV-infected again".
