Killer T cell attacking cancer

October 24, 2019

The green cell you see here is a killer T-cell of the immune system, which is attacking the cancerous red and blue cell. You can tell when the killer T-cell has recognised the cancer cell because the two dots move around and contact the target. The killer T-cell then spreads out over the cancerous cell Passing the video through a filter makes the killer T-cell look yellow and allows us to really see how it focuses on the cancer cell These killer T-cell are constantly hunting down dangerous cells throughout the body and destroying them

    Sorry for disturbance:
    what are the two red dots called??

    I can say we are all fearfully and wonderfully made, our body has its own defense system to fight off diseases.

    You already have T-cells in your body. We produce them naturally.

    I was sorta wishing the blue ones were the T cells…there were a lot more of them than the green/yellow one. :/
    Hope the T cell has a big appetite =)

    …um T Cells are defense cells that are already in your body.

    Havent you ever heard of your immune system?

    Or did you think you survived this long on kisses from mommy?

  • Reply John Cheatham March 19, 2013 at 12:58 am

    The reason we continue to die from cancer is we deplete our body from Alkaline. We continue to go to these fast restaurant and eat french fries and greasy burgers. The fast food industry has eliminated vegetables which the body has to have in order to keep our cells health and alive…Send me and email and I can send some info that will change your life for the better or PM on FB

    For those of you wondering what the two red dots are, those are microtubule organizing centers. These allow the cytotoxic T cell to direct cytotoxic granules towards the cancer cell. These granules contain the components that kill the cancer cell.

    While immunotherapy (Infecting cancer cells so they can be targeted) is one of the promising fields for “truly aggressive” cancers 
    If our Immune cells targeted cancers every day – cancer cells wouldn’t stand a chance.

    Some questions about the cells used in the video
    Immune targeting (Self V’s Non-Self) 
    Were any of the cells modified to promote targeting?
    If not, as cancer cells are “Self” what do you suspect was being targeting on the cancer cell? 
    Could it be a common contamination in the cultured cancer cells used in the video, i.e. viral or mycoplasma?
    Could it be a component of the florescent stain used to label the cancer cells?

    Because someone tells you that this is a cancer cell, does not mean they are telling the truth. Oh yes, by the way I have a bridge to sell, is anybody up for purchasing my bridge.

  • Reply franz wetrfres June 23, 2016 at 2:00 pm

    OK, the reason that this is not a cancer cell, because it is physically impossible for a killer t cell to attack and consume a cancer cell. The reason is that the immune system looks at all cells including cancer cells as its own and will not attack and kill them. If the immune system did this it would be called an auto immune disease. The reason for this is basic chemistry and like charges repel each other; though a very simple almost to simple explanation, but that is the way it is.
    That being said, the body can kill cancer cells through a complicated but direct way and what you see in this depiction just isn't it.
