Researchers Find Precise Way To Kill Cancer Cells

The researchers deploy optogenetics, an approach that uses optical systems to control cell functions, to focus a light beam on a target smaller than one cell.

“That is how we can use light to very precisely target a cell and turn on its death pathway,” Mr. Zhang said in the press release.

In addition to killing the cancer cell, another intended outcome is to trigger the immune system to respond to the light. Mr. Zhang said that the ruptured cells release cytokines, a type of small protein, attracting white blood cells that help the immune system fight infection.
By killing cancer cells, the researchers hope to train T-cell white blood cells to recognize and attack the cancer, Mr. Zhang said.

The researchers made the cells respond to light by borrowing a light-activated gene from plants and inserting it into intestine cell cultures. They then attached those genes to the genes for a protein, RIPK3, that regulates necroptosis, a form of cell death caused by various stimuli.
