Seeing is Believing – Natural Killer Cells Attack Cancer

September 21, 2012 — 11 Comments

Seeing Is Believing.

For many people, only physical and concrete evidence is convincing. In essence, they need to see the actual event to fully believe it. With the advancement of scanning electron  microscopes, we now have the ability to actually witness immune cells attacking cancer cells.

Below are two videos of natural killer cells attacking and destroying cancer cells.

In the first video, at the top of the picture is a cancer cell (larger cell) and below it is a natural killer cell. The natural killer cell kills the cancer cell on contact. It binds to its target and then delivers a lethal burst of chemicals that produce holes in the target cells membrane. In the video you will see the cancer cell collapsing.

The second video is a time-lapse video of activated natural killer cells added to a culture of Ewing sarcoma cells. Ewing sarcoma is a rare bone cancer that attacks primarily in childhood or early adulthood. The flat, green cells are Ewing sarcoma, and the white, round, more active cells with red granules are the natural killer cells

Natural killer cells are the body’s first line of defense against cancer.

    I’m impressed. This was very helpful to me.


    thanks, John, great article. Was most interested in the movie showing how our bodies fight that awful cancer.


      Ron, yes, if we take care of our immune system it will take care of our bodies. Your body is well capable of fighting cancer. I advocate that you need the best of Western medical treatment: surgery, chemotherapy, and radiotherapy plus your body’s own natural defenses. I believe your immune system is the best oncologist in the world. Thanks for your comment.


    Now if they could just get this innoculation for the immune system to be trial tested and OK’d it would be AWESOME!


      Rachel, immunology is at the forefront of cancer research today. In fact, the most recent post on the American Cancer Society’s website (Research section) is entitled: Hope foundation gift helps study “natural killers” that can heal. However with over 200 different types of cancer, a universal inoculation doesn’t seem forthcoming. Nevertheless, major advances are being made against specific cancers. Unfortunately, it takes many years between a medical discovery and availability to the general public. Fortunately, there is much an individual can do to improve the health of their immune system.


    Thanks, John. Facinating stuff.


      Jerry, I agree. My heart’s desire is that anyone who is battling cancer, or under the threat of relapse, would be able to see this. Upcoming posts will stress how to restore the health of your immune system.


    That was amazing! Brings a whole new meaning to ‘natural born killers!’
