BIOL 5500 Exam 3 QUESTIONS AND ANSWERS Antibodies consist of two identical heavy chains and two identical light chains Regions of TCRs and BCRs that are particularly variable in their amino acid sequences are known for binding to antigen MHC molecules are recognized by T cells Based on your knowledge of MHC I and II, predict which cell type would be MOST likely not to express detectable MHC I erythrocytes -MHC I is present on nucleated cells. Which of the following cell types w...

1. Which of the following statements is true. A.) Signaling through the TCR is sufficient to activate naïve T cells B.) CD28 is a costimulatory molecule that is needed to activate naïve T cells C.) CD80 and CD86 interact with CD4 to inhibit TCR signaling D.) Costimulatory molecules activate phosphatases that inhibit Zap70 correct answer: B.) CD28 is a costimulatory molecule that is needed to activate naïve T cells 1. Which of the following statements is true? A.) ITIMs recruit ph...

start of chapter 7 Define clonal expansion and how it contributes to the activation of naïve T cells. (Hint: B7, CD28, and PAPCs are all involved at this point) - Clonal expansion is the proliferation of lymphocytes to produce identical cells. This means more naïve T cells can be activated by P-APCs. CTLA-4 and B7: a. What does CTLA-4 bind to? What is the result of this binding? b. What cell is responsible for putting-up CTLA-4 on its surface? c. Differentiate between the effects of B7 a...
