Chapter 9 | The Immune System
- Different MHC I molecules between donor and recipient cells can lead to rejection of a transplanted organ or tissue. Suggest a reason for this.
- If a series of genetic mutations prevented some, but not all, of the complement proteins from binding antibodies or pathogens, would the entire complement system be compromised?
- Explain the difference between an epitope and an antigen.
- What is a naïve B or T cell?
- How does the TH1 response differ from the TH2 response?
- In mammalian adaptive immune systems, T cell receptors are extraordinarily diverse. What function of the immune system results from this diversity, and how is this diversity achieved?
- How do B and T cells differ with respect to antigens that they bind?
- Why is the immune response after reinfection much faster than the adaptive immune response after the initial infection?
- What are the benefits and costs of antibody cross reactivity?
