Which of the following is true regarding antigen presentation to activate effector functions of T cells?
Which of the following is true regarding antigen presentation to activate effector functions of T cells?
- Only humoral immune responses require antigen presentation to activate T cell effector functions
- T cells do not require antigens to activate effector functions
- Antigen presentation can be done by various kinds of APCs besides dendritic cells (correct)
- Only dendritic cells can present antigens to activate T cell effector functions
What is the function of MHC molecules in antigen presentation to T cells?
What is the function of MHC molecules in antigen presentation to T cells?
- To activate effector functions of T cells
- To display peptides derived from protein antigens (correct)
- To capture and present antigens to trigger immune responses
- To produce protein antigens
How does the antigen receptor of a T cell recognize a complex of peptide antigen displayed by an MHC molecule?
How does the antigen receptor of a T cell recognize a complex of peptide antigen displayed by an MHC molecule?
- By recognizing only some amino acid residues of the peptide and the MHC molecule (correct)
- By recognizing all amino acid residues of the peptide and the MHC molecule
- By recognizing only polymorphic residues of the MHC molecule
- By recognizing only anchor residues of the peptide
