Question

Which of the following cell class II? types would be LEAST likely to express MHC A. B cells B. T cells C. Dendritic cells D. Thymic epithelial cells E. Vascular endothelial cells Which of the following is the BEST example of self-MHC restriction of T cells? A. A T-cell clone is deleted when it binds too tightly to self MHC. B. A T-cell clone responds more vigorously to a self-peptide than a foreign peptide. C. A T-cell clone recognizes foreign MHC. D. A T-cell clone only recognizes foreign peptides when presented by sel ???. Which of the following is an example of cross-presentation? A. An endogenous peptide being presented on MHC class I B. An exogenous peptide being presented on MHC class C. An endogenous peptide being presented on MHC class II D. An exogenous peptide being presented on MHC class II E. A B-cell antigen being presented to a T cell i tho sole of nincytosis in antigen presentation, and which cells

Explanation / Answer

1. T cells are least likely to express MHC class II.

2. T cell clone only recognizes foreign peptide when presented by self MHC is the best example of self MHC restriction of T cells.

3. An exogenous peptide being presented on MHC Class I is an example of cross presentation. It is the ability of antigen presenting cells to take up, process and present antigens on MHC class I to cytotoxic T cells.
