London, United Kingdom – Scientists in London have made a groundbreaking discovery by successfully using Crispr gene-editing technology to eliminate HIV from infected cells. The Nobel Prize-winning technology functions like molecular scissors, allowing scientists to remove or deactivate the “bad” bits of DNA within cells.
The ultimate goal is to completely rid the body of the HIV virus, a feat that current HIV medicines are unable to achieve. Although this breakthrough shows promise, more extensive research is required to ensure its safety and effectiveness before it can be considered a viable cure for HIV.
Presenting their early findings at a medical conference, the University of Amsterdam team emphasized that their work is still in the early stages and is merely a “proof of concept.” Dr. James Dixon from the University of Nottingham echoed this sentiment, stating that further examination of the full findings is necessary before any significant impact can be seen in HIV therapy.
While scientists continue to explore the potential of using Crispr against HIV, challenges remain. Dr. Jonathan Stoye from the Francis Crick Institute points out that fully eradicating HIV from all cells in the body poses significant difficulties. Concerns regarding off-target effects of the treatment and potential long-term side effects also complicate the development of a Crispr-based therapy for HIV.
HIV infects immune system cells, utilizing their machinery to replicate itself. Even with existing treatments, some infected cells can enter a dormant state, still containing HIV genetic material. This necessitates lifelong antiretroviral therapy for most individuals with HIV, as discontinuing medication can lead to virus reactivation and health complications.
While rare cases of HIV “cures” have been reported post-aggressive cancer therapy, such extreme measures are not recommended solely for treating HIV. The road to a viable Crispr-based therapy for HIV remains long, requiring rigorous testing and validation before becoming a routine part of HIV treatment protocols.
