5 cell images reveal the battle to kill cancer cells

1. If you want to choose a term that is most frightening to the world, there is no doubt that "cancer" will be among the best.

2. Today, with the rapid development of medical technology, cancer still kills millions of people every year. The human body is actually a "community" composed of cells. Every cell acts according to the rules, knowing when to divide and grow, and know how to combine with other cells to form tissues and organs.

3. Cancer cells are different from normal cells. The most prominent feature of cancer cells is infinite division and never stop, while normal cells do not grow indefinitely.

4. Once the cancer cells have split out enough "likes" and stand firm, they reveal their true colors - a group of "fire-fighting" cells.

5. They do not have any physiological functions beneficial to the body, but they continue to multiply and divide, one becomes two, two becomes four, and becomes eight... Cancer cells reproduce everywhere, frantically extracting nutrients from the body. Squeeze the living space of normal cells, block the pathway of blood circulation, release various toxins, and eventually drag the whole body, and there is a situation that no one wants to see...

6. However, cytotoxic T cells in the body are the nemesis of cancer cells, which constantly patrol the body to find and kill cancer cells or cells infected with dangerous viruses. When cancer cells encounter cytotoxic T cells or killer T cells, they can kill cancer cells. As shown in the figure, cytotoxic T cells are orange, and blue is cancer cells. Recently, researchers at the University of Cambridge in the United Kingdom have used the most advanced imaging technology to truly record the process of killing cancer cells.
