What else can I help you with?
What is meant CD8 or cytotoxic T cells?
A cytotoxic T-cell is a form of lymphocyte that is the "killer" T-cell. This cell engulfs damaged or viral/bacterial cells to stop them from infecting the blood.
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 type of cells are cytotoxic?
Cytotoxic cells are a type of white blood cell called cytotoxic T cells. These cells are important for the immune system's response to infection and cancer, as they can identify and kill infected or abnormal cells.
Which of the following substances does a cytotoxic T cell secrete to destroy a target cell?
Perforin and granzymes are substances secreted by cytotoxic T cells to destroy target cells. Perforin creates pores in the target cell's membrane, allowing granzymes to enter and initiate cell death.
What is the role of cytotoxic T cells and describe their mechanism of action?
The role of cytotoxic T cells is to alert Class I MHC molecules to a foreign antigen. This is achieved by the foreign antigen associating with the MHC molecule and being moved out to the cell surface, where the cytotoxic T cell alerts the MHC molecule of the infection.
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.
What does T cytotoxic cell do?
A cytotoxic T cell kills cells that have been infected by a virus or bacterium. It does this by puncturing the cell's membrane and by emitting a toxin that kills 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.
How many customers does AT and T cellular have?
cytotoxic t cell and helper t cell
What type of cells are cytotoxic?
Cytotoxic cells are a type of white blood cell called cytotoxic T cells. These cells are important for the immune system's response to infection and cancer, as they can identify and kill infected or abnormal cells.
How do cytotoxic T cells kill infected or abnormal cells in the body?
Cytotoxic T cells kill infected or abnormal cells by releasing toxic substances that puncture the cell membrane, triggering cell death.
Which of the following substances does a cytotoxic T cell secrete to destroy a target cell?
Perforin and granzymes are substances secreted by cytotoxic T cells to destroy target cells. Perforin creates pores in the target cell's membrane, allowing granzymes to enter and initiate cell death.
What type of cell is known as the body's defense fighters?
Cytotoxic T cells
What is the role of cytotoxic T cells and describe their mechanism of action?
The role of cytotoxic T cells is to alert Class I MHC molecules to a foreign antigen. This is achieved by the foreign antigen associating with the MHC molecule and being moved out to the cell surface, where the cytotoxic T cell alerts the MHC molecule of the infection.
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.
What cell stimulates both antibody secreting cells and cytotoxic immune cells?
Helper T cells, specifically CD4+ T cells, play a crucial role in stimulating both antibody-secreting B cells and cytotoxic T cells (CD8+ T cells). Upon activation by antigen-presenting cells, helper T cells secrete cytokines that promote B cell differentiation into plasma cells, which produce antibodies. Additionally, they enhance the activation and proliferation of cytotoxic T cells, enabling them to target and eliminate infected or cancerous cells. This coordination is essential for an effective adaptive immune response.
