Innate immune system can kill HIV when a viral gene is deactivated
Human cells have an intrinsic capacity to destroy HIV. However, the virus has evolved to contain a gene that blocks this ability. When this gene is removed from the virus, the innate human immune system destroys HIV by mutating it to the point where it can no longer survive. This phenomenon has been shown in test tube laboratory experiments, but now researchers have demonstrated the same phenomenon in a humanized mouse model, suggesting a promising new target for tackling the virus.
