These substances are used to destroy virus-infected cells.

He also studied the mechanisms that regulate production of interferons, the small proteins produced by virus-infected cells to fight virus replication.

In addition, NS1 is probably able to suppress the interferon response in the virus-infected cell leading to unimpaired virus production.

Their purpose is to induce apoptosis within virus-infected cells, thus destroying them.

It plays an important role in the immune system by attacking virus-infected cells, foreign cells, and cancer cells.

Killers are known to attack virus-infected cells and cells that have become cancerous.

This thereby inhibits the CD8-restricted cytotoxic T cell response against virus-infected cells.

So they mixed virus-infected cells and white blood cells from the mice.

They also limit viral spread by increasing p53 activity, which kills virus-infected cells by promoting apoptosis.

There is evidence that this protein makes infected cells more adhesive, thereby promoting the interaction between virus-infected cells and immune system cells.
