Final answer:
MHC class I molecules are responsible for binding to CD8-positive (cytotoxic) T cells, which then act to eliminate infected cells and amplify the immune response.CD8-positive T cells
Step-by-step explanation:
MHC class I molecules bind to CD8-positive T cells, commonly referred to as cytotoxic T lymphocytes (CTLs). These cells play a crucial role in the body's immune defense by directly killing infected cells through a process called apoptosis and by secreting cytokines to amplify the immune response. While MHC class II molecules interact with CD4-positive T cells, which become helper T cells, it's the MHC class I that presents antigens to the CD8-positive T cells, making them vital for fighting intracellular pathogens like viruses that infect nearly all bodily tissues.
