Scientists Just Used CRISPR to Completely Erase HIV from Human Cells — and the Cells Stayed Immune Forever After
A team of experts at Temple University in Philadelphia has made a major leap in the fight against HIV by deploying CRISPR/Cas9—a precise DNA-cutting tool—to wipe out the virus’s embedded code directly from human immune cells grown in the lab.
In a fresh 2024 experiment, they targeted dormant T cells carrying hidden HIV-1, snipping away the full viral genome so thoroughly that the cells not only cleared the infection but also fended off fresh viral attacks without producing any offspring viruses.
This “scarless” erasure offers a stark contrast to standard drugs, which merely keep the virus in check; here, the goal is total removal from hard-to-reach hideouts, paving the way for what could become a one-time, lasting fix. While still in early testing stages, including safety checks in people, these lab wins have sparked real optimism that ending HIV’s grip might soon move from dream to reality for millions worldwide.
