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 else can I help you with?
Cells that directly attack and kill other cells?
Cells that directly attack and kill other cells are known as cytotoxic cells. These can include natural killer (NK) cells, cytotoxic T cells, and macrophages. They play a crucial role in the immune system's defense against infected or abnormal cells.
What does a cytotoxic B cell do?
A cytotoxic B cell produces antibodies that can directly bind to and kill infected or abnormal cells. These antibodies mark the target cells for destruction by other immune cells, leading to the elimination of the threat.
What cells are mainly used to kill infectious microbes and tumor cells?
The cells mainly used to kill infectious microbes and tumor cells are immune cells called cytotoxic T cells and natural killer cells. These cells can recognize infected or abnormal cells and destroy them by releasing toxic chemicals or by inducing programmed cell death.
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.
What is Tc cells?
Tc cells are cytotoxic cells that are "effetors" of cellular immunity that carry out the attack on a foreign cells in other words Tc cells kill cells that have been infected by a foreign substance
What are cytotoxic T cells for?
they are in our bodies to attack and kill infected 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.
Are lymphocytes that directly kill virus- infected cells?
T cytotoxic cells

Are cytotoxic T cells a type of T cell clone?
Yes, cytotoxic T-cells are a subset of T-cells that in contrast to helpter T-cells express CD8.
What is Tc cells?
Tc cells are cytotoxic cells that are "effetors" of cellular immunity that carry out the attack on a foreign cells in other words Tc cells kill cells that have been infected by a foreign substance
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 Type of T cell that directly kills virus infected body cells and some tumor cells?
Cytotoxic T cells (CD8+ T cells) are responsible for directly killing virus-infected body cells and some tumor cells by releasing cytotoxic molecules like perforin and granzymes. They recognize infected or abnormal cells by recognizing antigens presented on the cell surface.
The only T cells that can directly attack and kill other cells are the?
Cytotoxic cells
