Jim, a thirty-one-year-old male, is rushed from a local state park to the emergency room. The skin on his face, torso, and limbs is markedly swollen. He is having trouble swallowing, and his breathing is labored and difficult. He feels faint, and a blood pressure determination reveals a systolic/diastolic pressure of 90/60 mmHg. His friends report that he had eaten a large picnic lunch earlier in the day. Later, he had taken a walk through a wildflower garden that was fully in bloom. Wandering off a path and into the woods, he had disturbed a wasp's nest. After being stung, he had to run through a large patch of poison ivy in order to escape the wasps. Returning quickly to his friends, he rapidly developed the symptoms described above and was rushed to the hospital. 7. List the steps in the activation of B cells. Make sure to include these terms: sensitization, antigen, clones, plasma cells, memory cells, antigen-presenting cells, mitosis, antibody, etc. 8. List the steps in the activation of T cells. Make sure to include these terms: antigen-presenting cells, MHC I and II, antigen, sensitization, clones, T-cytotoxic, T-helper, T-suppressor, perforin and lymphotoxin, etc. 9. Before this form of allergic reaction can occur, what type of defensive cell has to have previously encountered the allergen in order to sensitize the individual? 10. What are the 4 possible types of allergic reactions? Describe/explain each. What are the differences between immediate and delayed hypersensitivities? 11. Which type of allergic reaction was this? 12. Was there an immunoglobulin involved in the above reaction? If so, which type? 13. What types of cells will then carry this antibody on their membranes in anticipation of a second exposure to the antigen? 14. How do these cells respond when they next encounter the antigen? What chemical signals do they release? 15. How does the release of these chemical signals lead to the pathological symptoms observed? List each of the symptoms and explain how the chemical signals would cause them. 16. Why would epinephrine be a good treatment for the patient's condition? (i.e., explain how epinephrine would help to alleviate each of the pathological symptoms?) Explain briefly.
