Cytotoxic T cells can destroy cancer cells by means of a secretion called?

Cytotoxic T cells (also known as CD8+ T cells) can destroy cancer cells through a process called cell-mediated cytotoxicity. This process involves the secretion of perforin and granzymes by the cytotoxic T cells. Perforin creates pores in the target cell's membrane, allowing granzymes to enter the target cell. Granzymes are proteases that induce apoptosis (programmed cell death) in the target cell, effectively killing it. This mechanism is a crucial part of the immune system's ability to recognize and eliminate cancerous or infected cells.

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.
