Killer T cell attacking cancer

Watch this immune system defending T cell attacking a cancer cell. Alex Ritter, a PhD student at Cambridge, shot this “using an Andor Revolution spinning disk system with an Olympus microscope.” The T cell, about one-tenth the width of a human hair, is being shown at 92 times its actual speed.

Alex’s Lab professor, Gillian Griffiths:

“Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or cancerous cells, without destroying healthy cells surrounding them… By understanding how this works, we can develop ways to control killer cells. This will allow us to find ways to improve cancer therapies, and ameliorate autoimmune diseases caused when killer cells run amok and attack healthy cells in our bodies.”

Incredible. Truly.
