Verified
A cell has experienced a mutation that results in uncontrolled cell division. Which of the following types of defense cell would most likely interact with the mutated cell and how?
A) This is a cytotoxic T cell that interacts with the mutated cell through an MHC class I molecule.
B) This is a cytotoxic T cell that interacts with the mutated cell through an MHC class II molecule.
C) This is an antigen-presenting cell that interacts with the mutated cell through an MHC class I molecule.
D) This is an antigen-presenting cell that interacts with the mutated cell through an MHC class II molecule.
Uncontrolled Cell Division
The process by which cells divide without regulation, often leading to tumor growth and cancer.
Cytotoxic T Cell
A kind of white blood cell that eliminates cancerous cells, cells infected mainly by viruses, or cells harmed in various manners.
MHC Class I
(Major Histocompatibility Complex Class I) are molecules found on almost all nucleated cells that present peptide antigens to the immune system, particularly to CD8+ T cells.
- Recognize the connection between particular immune cells (such as cytotoxic T cells, NK cells) and their designated targets, detailing the mechanism of action.

Final Answer :
A
Explanation :
Cytotoxic T cells are responsible for killing cancerous or virus-infected cells. They recognize these abnormal cells through interactions with MHC class I molecules, which present endogenous antigens (including mutated proteins from cancer cells) on the surface of all nucleated cells.
