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

A cancer-killing virus has stopped pancreatic tumours from growing and spreading in three people in an initial safety trial, ...

Long after the acute infection fades, pieces of the virus behind COVID-19 can linger in the body and quietly sabotage the immune system. Instead of harmless debris, new research suggests these ...

Viruses have spent billions of years perfecting the art of invading cells, hijacking their machinery and spreading with ruthless efficiency. Now researchers are turning that evolutionary expertise ...

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 ...

For decades, HIV treatment has depended on one hard truth: once medication stops, the virus usually comes roaring back. Modern antiretroviral drugs can suppress HIV so effectively that many people ...

University of Exeter scientists studied chemical communication by phages (viruses that infect bacteria). The phages assessed in the study have two choices when they enter a cell: lie dormant or kill ...

LONDON (Reuters) - In a significant step forward for the development of a potential new cancer treatment, scientists have found how a common cold virus can kill tumors and trigger an immune response, ...

Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small transporter called MurJ that is a vital part ...

Human cervical cancer cells (shown in gray) undergo widespread cell death after Cas12a2 treatment, as indicated by markers of apoptosis (in magenta). A new technology uses a relative of the ...
