Question

The primary function of MHC class I molecules is to present:

• A. Bacterial polysaccharides to B cells
• B. Viral peptides to CD8+ T cells
• C. Self-antigens to NK cells
• D. Peptides to CD4+ T cells

Hint:

MHC class I molecules are primarily involved in presenting intracellular antigens to CD8+ cytotoxic T cells.

Answer 1

The Correct Option is B

MHC class I molecules present viral peptides to CD8+ T cells, which are essential for recognizing and eliminating infected cells. This process is crucial for cellular immunity and the defense against viruses.
