Enhanced NK Cell Therapy Shows Promise for HIV Control
Scientists have developed an enhanced NK cell therapy that could potentially allow people with HIV to control the virus without the need for lifelong antiretroviral treatment (ART).
Currently, over 30 million people worldwide living with HIV rely on daily ART to manage the virus. While effective at suppressing HIV, ART doesn’t eliminate it, leaving it hidden in reservoirs within the body where it can reactivate if treatment is stopped.
researchers at case Western Reserve University adn the University of Pittsburgh have made a breakthrough using natural killer (NK) cells – immune cells that naturally target virus-infected and tumor cells. They found that NK cells extracted from HIV-positive patients can be expanded and enhanced in the lab to more effectively target and reduce the virus in these reservoirs.
Key Highlights:
* NK Cell Immunotherapy: This approach builds on existing cancer therapies using NK cells and aims to reduce the viral reservoir to a level where long-term immunological control of HIV is possible without ART.
* Lab Enhancement: Researchers can improve the ability of NK cells to fight HIV.
* Future Goals: The team plans to test if these enhanced NK cells can be used as an “off-the-shelf” therapy. They will use advanced animal models and aim to begin clinical trials in people living with HIV within the next two years.
* Strong Research Foundation: Case Western Reserve University boasts a long history of HIV research, including a National Institutes of Health-designated Center for AIDS Research and a Center for Excellence on the Impact of Substance Use on HIV.
* Collaborative Effort: The research was enabled by blood donations from people living with HIV and collaboration between patients, researchers, and institutions.
This research offers a promising new avenue for achieving long-term HIV remission and potentially freeing individuals from the burden of daily medication.
