Researchers have made many modifications to the CRISPR system since it was first developed. CRISPR is a DNA-editing tool that ...

A new kind of CRISPR that destroys cells rather than gene editing them has shown potential for killing sick cells while leaving healthy cells untouched. CRISPR-mediated gene editing technology has ...

Researchers have developed a CRISPR system, Cas12a2, that kills targeted cells by shredding their DNA, showing high specificity for cancer or virus-infected cells while sparing healthy ones. Tests in ...

T cells are some of the immune system's most important warriors. They can stop tumor growth and even fight off severe ...

It's a virus that can strike with unrelenting force. The kind of care need to knock it out is often not fully available in a ...

A new study from the University of Gothenburg may help guide the development of better influenza vaccines. Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce ...

There’s a virus you may have never heard of before that is estimated to infect up to 90 percent of people and lurks quietly in your cells for life—but if it becomes activated, it will destroy your ...

When a virus enters the lungs, the immune system has to react fast. The lung maintains its own community of immune cells capable of mounting a local defense on the spot. Researchers from the ...

A new kind of CRISPR that destroys cells rather than gene editing them has shown potential for killing sick cells while leaving healthy cells untouched. The technology has largely been tested in cells ...
