Which is not applicable to innate immunity? A) O It is faster than adaptive immunity in responding to pathogens. B) OIt can involve toll-like receptors. C) O It may use complement to kill pathogens. D) O The inflammatory response is part of innate immunity. E) O It can make one resistant to future infections.

4. The variable region can be found in Fab B). Fc C). CL D). TLR E). A, B and C 5. Which event primarily takes place in the thymus? A). Production of thyroid hormone B). Clonal expansion C). Antigen activation of lymphocytes D). Development of memory cells E). None of the above.

Johnny has just been infected and needs your help in letting him know how his body is fighting the infection. To do so, describe how the innate and adaptive immune systems work together. You should address the following: 1. define adaptive and innate immunity; 2. Describe the role of natural killer cells (how do they work); 3. what are antigen presenting cells and what is their function, what are MHCs?; 4. describe the role of the complement system; 5. what is the role of interferons?; 6. How do helper T cells, cytotoxic T cells and B lymphocytes work make sure you address adaptive immunity memory?; 7. Define HIV, which cells do they attack and why do some individuals develop persistent lymphadenopathy (swollen or enlarged lymph nodes)?

Which of the following describes the self-tolerance of adaptive immunity?   A)  a given immune response acts against a specific antigen possessed by a pathogen B)  both cells and antibodies are involved in immune responses C)  immune responses against previously encountered pathogens are faster and more potent D)  immune responses against the body's own molecules do not normally occur E)  pathogens stimulate cells involved in adaptive immunity

Rebecca developed measles as a young child. As a teenager, she is re-exposed to the measles virus during an outbreak at her high school. What will most likely prevent Rebecca from experiencing any signs or symptoms of measles? As a result of her childhood exposure, her immune system can perform enhanced inflammatory response. As a result of her childhood exposure, her immune system can perform enhanced phagocytosis of virus-infected host cells. She has memory innate immune cells as a result of her childhood exposure. They would be primed to activate rapidly upon subsequent exposure to the same virus during the secondary immune response. She has memory B cells as a result of her childhood exposure. They would be primed to activate rapidly upon subsequent exposure to the same virus during the secondary immune response.

Interferon aims to protect cells against which of the following? 1) Intracellular bacteria 2) Helminth infection 3) Viral infections 4) Attack by immune complexes
