A cure for HIV could be a step closer after researchers found a new way to force the virus out of hiding inside human cells.
The virus’s ability to conceal itself inside certain white blood cells has been one of the main challenges for scientists looking for a cure. It means there is a reservoir of HIV in the body, capable of reactivation, that neither the immune system nor drugs can tackle.
In a groundbreaking advance, scientists have successfully used CRISPR/Cas9 gene editing to eliminate HIV-1 DNA from the genomes of human immune cells.
Unlike existing treatments that suppress the virus, this method completely removes the genetic blueprint of HIV from infected T-cells.
In lab tests using cells from real patients, not only was the virus removed, but the edited cells also resisted reinfection—an unprecedented level of viral control.
The study marks a crucial step toward a potential cure for HIV. Current antiretroviral therapies require lifelong adherence and only manage the infection; stopping treatment typically allows the virus to return. By contrast, the CRISPR technique offers a permanent solution by targeting and excising the virus at the genetic level, with no observed toxicity.
This breakthrough may pave the way for clinical treatments that fully eradicate HIV reservoirs in the body—long considered one of the biggest challenges in the global fight against the disease.
