Cytotoxic T cells can destroy cancer cells by means of a secretion called?

∙ 12y ago
Cytotoxic T cells (also known as CD8+ T cells) can destroy cancer cells through a process called cell-mediated cytotoxicity. This process involves the secretion of perforin and granzymes by the cytotoxic T cells.
Perforin creates pores in the target cell's membrane, allowing granzymes to enter the target cell. Granzymes are proteases that induce apoptosis (programmed cell death) in the target cell, effectively killing it. This mechanism is a crucial part of the immune system's ability to recognize and eliminate cancerous or infected cells.

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.
Can't you use ultra violet radiation to destroy cancer cells?
no u.v. light causes skin cancer
What cells primarily target cancer cells?
Cells of the immune system, particularly certain types of white blood cells, primarily target cancer cells. The main types of immune cells involved in targeting cancer cells include: Cytotoxic T Cells (CD8+ T Cells): These cells directly attack and destroy cancer cells by recognizing specific antigens present on the surface of the cancer cells. Natural Killer (NK) Cells: NK cells are a type of lymphocyte that can recognize and kill abnormal cells, including cancer cells, without prior sensitization or the need for specific antigens. Macrophages: Macrophages are immune cells that engulf and digest foreign substances, including cancer cells, through a process called phagocytosis. They also play a role in presenting antigens to other immune cells to initiate an immune response against cancer. Dendritic Cells: Dendritic cells are antigen-presenting cells that capture antigens from cancer cells and present them to T cells, thereby activating an adaptive immune response against the cancer. Tumor-Infiltrating Lymphocytes (TILs): These are lymphocytes that have migrated into the tumor microenvironment and are involved in recognizing and attacking cancer cells. Cytokine-Induced Killer (CIK) Cells: CIK cells are a type of immune cell that has been activated and expanded outside the body and then reintroduced into the patient to target and kill cancer cells. These immune cells, along with other components of the immune system, form a complex network known as the immune response, which plays a crucial role in recognizing and eliminating cancer cells from the body.
Bronchoscopy may be used to examine and help diagnose what disorders?
diseases of the lung, such as cancer or tuberculosis; congenital deformity of the lungs; suspected tumor, obstruction, secretion, bleeding, or foreign body in the airways
Why is latitude 30 degree North called Cancer?
That is the latitude at which the constelation Cancer is located overhead.
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.
How is chemotherapy made?
Chemotherapy refers to the use of cytotoxic drugs in cancer treatment.'Chemo' means medicine or 'drug''therapy' means 'treatment'. Chemotherapeutic agents or drugs are 'magic bullets' that destroy the fast-dividing cancer cells. However these drugs are unable to differentiate between the normal cells and the cancer cells and they destroy the former too, in their war against cancer. This leads to certain side effects.
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.
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 are the cells called that police the body in blood and lymph to kill cancer cells and virus infected body cells?
White blood cells that directly destroy virus-infected and cancerous cells are called?
What colony stimulating factors assist with recovering from the cytotoxic effects of cancer chemotherapy?
C. white blood cells
A form of treatment in which drugs destroy cancer cells is called?
The form of treatment in which drugs are used to destroy cancer cells is called chemotherapy. Chemotherapy works by targeting rapidly dividing cells, which include cancer cells. It can be administered orally or intravenously, and it may be used alone or in combination with other cancer treatments such as surgery, radiation therapy, or immunotherapy, depending on the type and stage of cancer.
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.
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.
When and why used laser therapy in cancer treatment?
When: As early as you can. Why: T destroy the cancer sells completely.
Is cancer caused by microorganisms?
Yes, the bacteria that causes cancer is well... SHOCK HORROR! called cancer bacteria. Heliobacter pylori are known to cause stomach cancer very gradually and Salmonella typhi causes the uncommon gallbladder cancer. Hope this helps!
