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 else can I help you with?
What substances do T cells produce to destroy cells infected by a virus?
T cells produce cytokines, such as interferons and interleukins, that help enhance the immune response against virus-infected cells. They also release cytotoxic substances, like perforin and granzyme, which can directly kill infected cells. Additionally, T cells can activate other immune cells, like macrophages, to help eliminate virus-infected cells.
What kills cells infected with a pathogen?
Cells infected with a pathogen can be killed by the immune system through mechanisms such as releasing toxic chemicals, inducing programmed cell death (apoptosis), or activating immune cells like T cells and natural killer cells to target and destroy the infected cells.
An immune response in which t cells destroy antigens?
This process is called cell-mediated immunity. T cells, specifically cytotoxic T cells, recognize and destroy cells that are infected with a pathogen or abnormal cells, such as cancer cells. This immune response is crucial for clearing infections and providing immunity against future exposures to the same antigen.
In cell meditated immunity what binds to and tears open the cell membranes of invading cells or infected body cells?
T Cytotoxic Cells destroy infected body cells by making holes in the cell membranes using proteins called perforins. This allows water to rush into the cells, causing it to burst. They are actually called Killer T cells.
What is the function of the T helper cells?
T cells destroy pathogens.

What cells are crude weapons that release chemicals to destroy infected cells that they encounter?
t-lymbhocytic
What kills cells infected with a pathogen?
Cells infected with a pathogen can be killed by the immune system through mechanisms such as releasing toxic chemicals, inducing programmed cell death (apoptosis), or activating immune cells like T cells and natural killer cells to target and destroy the infected cells.
Cytotoxic T cells have the ability to?
Cytotoxic T cells have the ability to recognize and target infected or abnormal cells in the body by releasing toxic chemicals that induce cell death. This process helps to eliminate pathogens or cancerous cells, playing a crucial role in the immune response against infections and tumors.

May destroy infected cells select one a cytotoxic t cells b helper t cells c b cells d allergens e phagocytic cells?
a) Cytotoxic T cells are responsible for identifying and destroying infected cells by releasing toxic chemicals that induce cell death. Helper T cells aid in coordinating the immune response by activating other immune cells. B cells produce antibodies that can neutralize pathogens. Allergens are substances that can trigger allergic reactions. Phagocytic cells, such as macrophages, engulf and digest pathogens or infected cells.
What do killer t cells do?
Killer T cells are a type of white blood cell that can recognize and destroy virus-infected cells, cancer cells, and other abnormal cells in the body. They play a crucial role in the immune system's response to infections and diseases. Killer T cells are able to identify specific antigens on target cells and induce their death.
In cell meditated immunity what binds to and tears open the cell membranes of invading cells or infected body cells?
T Cytotoxic Cells destroy infected body cells by making holes in the cell membranes using proteins called perforins. This allows water to rush into the cells, causing it to burst. They are actually called Killer T cells.
What is the function of a t-cells?
T cells destroy pathogens.
What are the cells called that police the body in blood and lymph to kill cancer cells and virus infected body cells?
The cells you are referring to are called natural killer (NK) cells. NK cells are a type of white blood cell that plays a crucial role in the immune system by identifying and eliminating cancerous cells and virus-infected cells in the body. They are part of the body's innate immune response.
What is the function of T-helper cells?
T cells destroy pathogens.
What is the function of the T helper cells?
T cells destroy pathogens.
