Here's how it works:
* Recognition: Cytotoxic T cells have receptors that recognize specific antigens displayed on the surface of infected cells. These antigens are fragments of the invading microbe that have been processed and presented by the infected cell.
* Activation: When a cytotoxic T cell encounters an infected cell, it becomes activated. This activation process involves the release of signaling molecules that further stimulate the T cell.
* Destruction: An activated cytotoxic T cell releases cytotoxic molecules, such as perforin and granzyme, that directly kill the infected cell. Perforin creates pores in the cell membrane, allowing granzyme to enter and induce programmed cell death (apoptosis).
By targeting and eliminating infected cells, cytotoxic T cells help prevent the spread of infection and protect the body from disease.
