QUESTION 11 How is the immune system able to recognize a limitless number of different antigens and epitopes? While each lymphocyte carries receptors that recognize only one type of epitope, the immune system produces a wide variety of lymphocytes each of which carries unique receptors A genetic "memory" of the pathogens your parents encountered (and their parents and so on) is passed on to each generation, increasing the number of possible responses over time. Each lymphocyte is coated with many...

Explain how the adaptive immune response is able to generate the diversity of antigen receptors necessary to recognize the multitude of foreign antigens. Explain how clonal selection contributes to the development and expansion of antigen specific lymphocytes that do not respond to self. Distinguish cytokines and chemokines and their roles in the immune response What are the 3 roles of antibody in the immune response What are the two types of T cells that contribute to cellular immunity? What are...

What’s the difference between a primary immune response and secondary immune response? Answer both in terms of the physiological responses and in terms of the mechanism by which it is achieved. Adaptive immunity is a response to a specific antigen. How does the adaptive immune system mount a specific response to an invading antigen? How is it possible to mount such a response to a wide array of antigens?
