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. The molecules that would otherwise reveal the cancer to the immune system are lost, and killer T cells move past, unaware of the danger the cancer cell could cause.

Killer T-cells will attack only a single specific antigen. The molecules that would otherwise reveal the cancer to the immune system are lost, and killer T cells move past, unaware of the danger the cancer cell could cause. In the past few years, cancer immunotherapy has emerged as a safe and effective alternative for treatment of cancers that do not respond to classical treatments, including those types with high aggressiveness. New immune modulators, such as cytokines, blockers of CTLA-4 (cytotoxic T-lymphocyte-associated protein 4) and PD-1(programmed cell death protein 1)/PD-L1 (programmed … The big difference being, I never feel sorry for the cancer cell.
The speed … It is like watching a National Geographic wild animal film. The key to winning the battle is time – reaction time. Natural killer (NK) cells and NKT cells are subsets of lymphocytes that share common ground.

Natural killer T-cells: Natural killer T-(NKT)-cells are not the same thing as natural killer cells, but they do have similarities. Coloured scanning electron micrograph (SEM) of T-lymphocyte killer cells attacking a cancer cell.

One of these cells (at centre) has attached itself to a large undifferentiated cancer cell (at left) and is attacking it.

Check out the rest of the series here: *****bit.ly/A6bwCE In this video we see a killer T cell of the immune system attacking a cancer cell. Four small rounded killer T-lymphocyte cells, a type of white blood cell (leucocyte), are seen at right.

NKT cells are cytotoxic T-cells that need to be pre-activated and differentiate to do their work.

Researchers at Cardiff University have discovered a new type of killer T-cell that offers hope of a "one-size-fits-all" cancer therapy. This video is entitled: Cytotoxic T cells killing cervical…

Both can rapidly respond to the presence of tumor cells and participate in anti-tumor immune … The science behind harnessing the immune system to fight cancer is complicated, but a new study discovered a simple, practical way to use light and optics to steer killer immune cells … To me, these videos of immune cells attacking cancer cells are fascinating. Professor Gillian Griffiths: "Cells of the immune system protect the body against pathogens.
Cambridge University's Under the Microscope is a collection of videos that show glimpses of the natural and man-made world in stunning close-up. “That’s a sure-fire way of escaping detection,” says Elliott, adding that it’s one of many escape methods cancer cells use. In this video we see a killer T cell of the immune system attacking a cancer cell.

Killer T-lymphocytes. Natural killer cells will attack any cancer cell. The following video shows an immune cell attacking and destroying a cancer cell.

Killer T-cells are part of the body’s specific immune system – also called acquired or adaptive immunity. “That’s a sure-fire way of escaping detection,” says Elliott, adding that it’s one of many escape methods cancer cells use. Professor Gillian Griffiths: “Cells of the immune system protect the body against pathogens.
