Two chemicals boost immune cells' ability to fight HIV without gene therapy

...le HIV must constantly divide in order to continue performing their protective functions. The massive amount of division prematurely shortens these cells' ends, or telomeres, ultimately exhausting the immune system. UCLA's previous research shows that telomerase rejuvenates the telomeres and allows the immune ...
