Natural killer (NK) cells are a type of white blood cell that can recognize and kill cancerous cells, as well as virus-infected cells. They work by releasing toxic substances that induce apoptosis (cell death) in the target cells. NK cells are a key part of the body's immune system for eliminating abnormal or diseased cells.

When uncontrolled cell division occurs cells can become what?
When uncontrolled cell division occurs, cells can become cancerous. Cancerous cells can continue to divide and grow uncontrollably, forming a tumor. These cells can also invade surrounding tissues and spread to other parts of the body through a process called metastasis.
How does a mistake in mitosis of a cell affect its tissue?
If mitosis goes wrong, cancerous cells forms.
Why do cancer cells go through the cell cycle rapidly?
Cancer cells go through the cell cycle rapidly due to dysregulation of cell cycle checkpoints that normally control cell division. This dysregulation leads to uncontrolled cell proliferation and rapid growth characteristic of cancer cells.
Which cell produces perforin?
Perforin is produced by cytotoxic T cells (CD8+ T cells) and natural killer (NK) cells. It is used in these cells to induce cell apoptosis in target cells, such as infected or cancerous cells.
What two types of defects does a cancerous cell possess?
Cancerous cells can have both genetic defects, such as mutations in key oncogenes or tumor suppressor genes, and functional defects, such as uncontrolled proliferation and evasion of cell death mechanisms. These defects allow cancer cells to grow uncontrollably and spread to other parts of the body.
What cell recognizes and destroy non self cells?
Natural killer cells (NK cells) are a type of immune cell that recognizes and destroys non-self cells, such as infected or cancerous cells. NK cells use a variety of receptors to detect abnormal cells and trigger their destruction through mechanisms like inducing apoptosis.
What destroys the antigenic cell molecule in cell-mediated immunity?
killer T cells
What effects does cancer have on a cell cycle of a cancerous cell?
It can give cancer to all the other cells, so it causes more cells to be cancerous. It goes all around the body and the number of the cancer cells will get much more than the first.
How is cancer is relates to cell cycle?
Cancer is related to the cell cycle because when a person gets infected, the cancerous cells attack healthy cells and then mutate the cells and then it rapidly creates new, mutated cells. The mutated cells then attack more healthy cells and the process is repeated. Cancerous cells can be killed with radiation
Why does aids leaves us unable to cope with infections or cancerous cells?
AIDS leaves us unable to cope with infections or cancerous cells because having AIDS can lead to HIV, which destroys out helper T cells. The body can no longer protect itself from the diseases that may attack it...
What is the definition of T Cell?
A destroyer T cell scans other cells for infection, and then destroys them.
Which type of white blood cells is produced in thymus and destroys the cell membranes of bacteria?
t-cells
What goes wrong with a normal cell when it becomes cancerous?
A normal cell turns cancerous when there is damage between a few of the genes that are in control of cell growth. These cells will eventually invade the blood supply and kill the host.
What does negative malignant cells mean?
A malignant cell is a cancer cell. Once that is growing out of control. No malignant cell means the absence of cancer cells. This means the observed cells are healthy.
Can a biologist learn about the cell cycle by studying cancer cells?
Yes, cancerous cells don't die when they're supposed to.
When uncontrolled cell division occurs cells can become what?
When uncontrolled cell division occurs, cells can become cancerous. Cancerous cells can continue to divide and grow uncontrollably, forming a tumor. These cells can also invade surrounding tissues and spread to other parts of the body through a process called metastasis.
What kind of cell don't respond to normally to the bodys control system for cell division and divide excessively?
Cancerous cells.
