'Murderous army' in human blood cells

White blood cell T is like a "killer army", scouring and secrete cytotoxic toxins to destroy cells infected with viruses or cancer.

White blood cells T - "Murderous army" in human blood cells

"Inside us hides a murder army, whose main function is to search for a constant kill," said Professor Gillian Griffiths, director of the Cambridge Medical Research Institute, when he published the study details. "These cells patrol the human body, identify and destroy cells infected with viruses or cancer cells, with high accuracy and efficiency."

According to the Washington Post, our blood contains billions of white blood cells called T cells , researchers estimate one teaspoon of blood contains 5 million of these cells, and each cell is constantly searching and destroying. Cells infected with the virus.

First, T cells will probe the surface of the strange cell, identify it, and then inject a deadly protein called cytotoxic. " The fate of strange cells is that, we just sit and watch it wither and die, " Griffiths said. " After that, T-cells continued to move, rushing to find other victims."

British scientists yesterday created high-resolution 3D video, using time-lapse technology to reconstruct T-cell activity images. Time-lapse is a still-image collage technology that allows fast rewinding. Real-time but still clearly shows the operation of the compounded object.

In the video, T cells are orange or green. They move, search and attack blue cancer cells by injecting them with red cytotoxic toxins .
