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 perforin?
Perforin is a protein released by cytotoxic T cells and natural killer cells as part of the immune response against infected or abnormal cells. It creates pores in the target cell's membrane, leading to cell death by inducing apoptosis. Perforin plays a crucial role in the body's defense against pathogens and cancer cells.
Cytotoxic T cells can destroy cancer cells by means of a secretion called?
Cytotoxic T cells can destroy cancer cells by means of a secretion called perforin. Perforin is a protein that forms pores in the membrane of target cells, allowing toxic enzymes to enter and induce cell death.
How are cytotoxic t cells programmed to kill infected cells?
Cytotoxic T cells are activated by antigen-presenting cells, such as dendritic cells, presenting antigens from pathogens. This interaction triggers the release of cytotoxic granules containing enzymes like perforin and granzymes. Perforin creates pores in the target cell's membrane, allowing granzymes to enter and induce apoptosis, killing the infected cell.
What kills invading cells by drilling a hole in cell membranes?
Perforin, a protein released by cytotoxic T cells and natural killer cells, forms pores in the cell membranes of invading cells. This disruption leads to osmotic imbalance, cell death, and elimination of the invading cell.

Cell death caused by perforin and granzymes is caused by?
Perforin creates pores in the target cell membrane, allowing entry of granzymes. Granzymes are proteases that induce cell death by activating enzymes in the target cell that trigger apoptosis, ultimately leading to cell death.

Does the mechanism of the lethal hit of cytotoxic t cells and nk cells involves a protein called perforin?
Yes, both cytotoxic T cells and NK cells use perforin as a key component of their mechanism to induce cell death in target cells. Perforin creates pores in the target cell membrane, allowing entry of pro-apoptotic proteins that trigger cell death. This process is important for the immune system to eliminate infected or abnormal cells.

How do you increase perforin in the body?
Perforin is a protein released by cytotoxic T cells to induce cell death in target cells. To potentially increase perforin levels in the body, one approach could be to enhance the activation and function of cytotoxic T cells through strategies like regular exercise, maintaining a healthy diet, managing stress, and ensuring proper sleep. Additionally, certain supplements like Vitamin D have been associated with immune system health and may support cytotoxic T cell function, but it's important to consult a healthcare provider before taking any new supplements.
What is perforin produced by?
produced by killer T-cells to lyse their target
What is another name for the galvanic cell?
A battery that produces electricity
What is cell division that produces sex cell?
meiosis
What is a cell that produces a signal molecule?
A cell that produces a signal molecule is known as a signaling cell or secreting cell. These cells release signaling molecules, such as hormones or neurotransmitters, which can travel to target cells to initiate a response.
