Which of the following substances does a cytotoxic T cell secrete to destroy a target cell?
Perforin!
Which cell produces perforin?
Cytotoxic T-cells
Cytotoxic T cells can destroy cancer cells by means of a secretion called?
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.
What is produced by T cells?
Well. If you get a cut tcells come to help heal it so you feel all better. tcells are really good for your body. They help out all the cuts you have. Good luck................................... with all your cuts. Dont worry tcells where be there always for all of your cuts. once again GOOD LUCK....................................
How do T cells destroy infected or diseased cells?
Cytotoxic T-cells kill infected cells in one of two ways: 1. By interaction with Fas ligand on T-cell with Fas molecule on target cell (induces apoptosis). 2. Release of lytic granules containing granzymes (also induces apoptosis) - For this, the T-cell needs to form pores in the target cell using perforin and granulysin.
What causes transmembrane channels in target cells?
Perforin
What is perforin produced by?
produced by killer T-cells to lyse their target
Which of the following substances does a cytotoxic T cell secrete to destroy a target cell?
Perforin!
Which cell produces perforin?
Cytotoxic T-cells
Cell death caused by perforin and granzymes is caused by?
I think it may be caused by CTLs
Does the mechanism of the lethal hit of cytotoxic t cells and nk cells involves a protein called perforin?
TRUE

Cytotoxic T cells have the ability to?
It releases perforin and granzymes which kills the infected cells.
What is the process called when a cell attacks a bacterium?
There are many different ways in which the body's cells can discourage bacteria. In general, all methods by which the body attempt to fight off foreign particles are known as immune responses. If you're asking what the process by which a macrophage eats a bacterium, its called "Phagocytosis". But there are many other ways of killing bacteria- for example your body uses Perforin to poke holes in bacteria in a process known as the MAC (membrane attack complex) attack.
What are natural killer cell?
Natural killer cells are non-phagocytic large granular lymphocytes. They kill virus-infected or cancerous cells before adaptive immune response. Natural killer cells recognise abnormal cells by its lack of cell-surface receptors such as major histocompatibility complex class 1 molecules. The natural killer cells will then secret perforin which forms pores in the cell membrane of the target cell. This results in either apoptosis or osmotic cell lysis. Natural killer cells also secrete alpha-defensins, a type of antimicrobial molecule, to directly kill bacteria by disrupting their cell walls.
