Microscopic Video of White Blood Cell Attacking Cancer Cell
In this microscopic video by University of Cambridge researchers, a killer T cell from the immune system attacks a cancer cell.
Cells of the immune system protect the body against pathogens. If cells in our bodies are infected by viruses, or become cancerous, then killer cells of the immune system identify and destroy the affected cells. Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or cancerous cells, without destroying healthy cells surrounding them.
