Cytotoxic T cells have the potential to recognize peptides presented by
|
|
only epithelial cells via MHC-I molecules
|
|
|
only epithelial cells via MHC-II molecules
|
|
|
cells nucleated through MHC-II molecules
|
|
|
cells nucleated through MHC-I molecules
|
Explanation:
Detailed explanation-1: -Cytotoxic T cells recognize foreign peptides in association with class I MHC proteins, whereas helper T cells recognize foreign peptides in association with class II MHC proteins.
Detailed explanation-2: -The surface of a cytotoxic T-cell has something called a CD8 receptor. The CD8 receptor interacts with cells called major histocompatibility complex (MHC) Class I molecules to recognize when healthy cells are infected. When the CD8 receptor recognizes an infected cell, it activates the cytotoxic T-cells.
Detailed explanation-3: -There are two types of MHC: MHC class I and MHC class II. MHC class I presents to cytotoxic T cells; MHC class II presents to helper T cells.
