4. Draw the structure of a functional antigen receptor on T cells. (1.0)
1. Identify the antigen receptor molecules and component proteins for B and T cells 2. Identify the function of an antigen receptor. 3. Describe the interaction between receptor and antigen.
True or False: Chimeric antigen receptor (CAR) T cells are cells that have been retrovirally transduced with a tumor- specific T-cell receptor in order to treat a leukemia.
ANSWER ALL QUESTIONS FULLY AND CORRECTLY
5-1 T cells recognize antigen when the antigen a. forms a complex with membrane-bound MHC molecules on another host-derived cell b. is internalized by T cells via phagocytosis and subsequently binds to T-cell receptors in the endoplasmic reticulum c. is presented on the surface of a B cell on membrane-bound immunoglobulins d. forms a complex with membrane-bound MHC molecules on the T cell e. bears epitopes derived from proteins, carbohydrates, and lipids. 5-2 a....
Describe the process of Antigen presentation to T cells, including how antigen is presented to T helper cells, what the antigen is like, accessory molecules involved etc., and the same for T cytotoxic cells.

O All of these O MHC-II O CD and TCR TCR O CD 1 pts Question 12 Question 10 1...
1. Compare and contrast the structure of antigen receptors on immune cells to that of MHC-I. 2. Compare and contrast the structure of antigen receptors on immune cells to that of MHC-II
5. Discuss the interaction between antigen receptor and epitope. 6. Describe the composition of T dependent and of T independent antigens
31. Which part of this T cell receptor is produced only AFTER the T cell has bound an antigen? A. The part labeled "A" B. The parts labeled "B" C. The entire T cell receptor D. None of it. It is all produced BEFORE antigen binding. E. T cells don't bind antigens; only antibodies do that. 37. How do Treg cells differ from Th cells? A. When Treg cells bind B7, they engulf and destroy it. B. Treg cells secrete...
