Cytotoxic T Cell (Noun)
Meaning
T cell with CD8 receptor that recognizes antigens on the surface of a virus-infected cell and binds to the infected cell and kill it.
Classification
Nouns denoting body parts.
Examples
- Cytotoxic T cells recognize antigens on the surface of a virus-infected cell through their CD8 receptor, leading to the lysis and death of the infected cell.
- CD8 positive cytotoxic T cells are crucial for clearance of viral infections by directly killing infected cells.
- A cytotoxic T cell possessing CD8 receptors provides immunity against viral infections by its ability to kill virus-infected cells.
- Upon recognizing antigens on a virus-infected cell surface, a cytotoxic T cell triggers a series of reactions that ultimately kill the infected cell through CD8 receptor interaction.
- Cytotoxic T cells expressing the CD8 receptor play a key role in cell-mediated immunity by eliminating infected cells that harbor viral peptides on their surface.
