Cytotoxic T cells are rapid killers of infected target cells. Within minutes of the interaction of a cytotoxic T cell with a target cell, the program of apoptosis in the target cell is initiated. This rapid activity is a consequence of The extremely rapid production of granzymes and perforin by cytotoxic effector cells upon encountering a target cell.
- A type of T cell known as a cytotoxic T cell (CD8+ T cell) is in charge of removing things that the immune system recognizes as dangerous.
- Cytotoxic T cells are essential for controlling bacterial growth and illnesses in the body.
- By instructing their targets to undergo apoptosis, cytotoxic T lymphocytes kill their prey.
- Cytotoxic T cells can instruct antigen-specific target cells to die within 5 minutes of coming into contact with them when they are mixed with target cells and quickly brought into contact by centrifugation.
- The speed with which cytotoxic T cells can induce apoptosis in their targets is due to the release of prepared effector molecules that trigger the target cell's own endogenous apoptotic pathway.
