What does T cytotoxic cell?
The cytotoxic T cell, when it finds cells displaying the wrong antigens, ruptures the cell membrane of the offending cell killing it. Cytotoxic T cells are effective against virus infected cells and cancer cells.
Cytotoxic T cells have the ability to?
It releases perforin and granzymes which kills the infected cells.
What is the role of the Cytotoxic T-cells?
Cytotoxic T cells destroy cancer cells. The cytoxic T cell comes into contrack with a cancer cell. The T cell recognizes that the cancer cell is "nonself" and causes the destruction of the cancer. Also, they can reject transplants like kidneys, resulting in the attack and destruction of the transplanted organ.
Does amino acid kill cancer cells?
No. Amino acids are the building blocks of proteins. They're not cytotoxic, which is what they'd need to be to kill cancer cells.
What does a cytotoxic B cell do?
There are no cytotoxic B cells, only cytotoxic T cells.
What do t cells do?
(t-cells) are involved in cell mediated immunity that can have memory of previous antigens(non self) that have invaded our body. cytotoxic tcells release preforin that destroy tumor cells or antigens helper tcells release cytokines/interlukins that help in more tcell differentiation
Cells that directly attack and kill other cells?
cytotoxic t cells
What colony stimulating factors assist with recovering from the cytotoxic effects of cancer chemotherapy?
C. white blood cells
Which major class of lymphocytes become cytotoxic T cells?
CD8 cells become cytotoxic T cells.
What are cytotoxic drugs?
Cytotoxic drugs-- Drugs that function by destroying cells.
What biological toxin is cytotoxic to rapidly dividing cells?
Colchicine, for one. It fouls up microtubule formation, and cells cannot divide without microtubules. Actually, any cancer chemotherapy agent is cytotoxic to rapidly dividing cells. That's why your hair falls out with certain types of chemo.
How do different cancer fighting drugs kill cancer cells by interrupting the cell cycle?
How does chemotherapy work? Normal cells in the body are constantly dividing to produce new cells in order to replace cells which are damaged or worn out. This process of normal cell division is very precisely controlled so that the number of new cells produced exactly matches the number of cells that need to be replaced. A cancer develops when a cell, or group of cells, escape from the normal control process and begin to divide and multiply in a random fashion which leads to an excessive number of cells being produced. Chemotherapy simply means treatment with drugs and can be used to describe the use of drugs in any illness. In cancer treatment 'chemotherapy' is shorthand for 'cytotoxic chemotherapy', the 'cytotoxics' being the main group of drugs used against cancer. The word cytotoxic means 'cell poison' and this actually describes how the drugs work. Cytotoxic drugs interfere with the process of cell reproduction so that when cancer cells come to reproduce (by dividing into two) they are unable to do so and die off. At the present time there are about a hundred different cytotoxic drugs approved for cancer treatment. All of these act in one way or another to interfere with the process of cell division. Unfortunately none of these drugs can tell the difference between normal cells and cancer cells. So they will all affect the reproduction of normal cells as well as cancer cells. This is why cytotoxic chemotherapy often causes unpleasant side-effects. Normal cells will usually recover from the effects of a dose of cytotoxic chemotherapy far more quickly than cancer cells. This is why chemotherapy is often given a number of short courses, with several weeks in between each course to allow for normal cells to recover. In this way treatment can be given which destroys cancer cells but causes no lasting injury to normal cells. Different cancers respond differently to cytotoxic chemotherapy. Some are very sensitive and can be cured with drug treatment. Others often respond to chemotherapy but are not sensitive enough to achieve cure. In these situations chemotherapy is given with the hope of prolonging good quality life. Others, despite all the different drugs available, remain almost completely resistant and unaffected by cytotoxic treatment. The great majority of drug treatment for cancer involves the use of cytotoxic drugs but there are a few types of cancer where treatment with hormones may also be helpful. This is considered in a separate question on hormone therapy for cancer.
