In the table below, identify the type of acquired immunity represented in each of the cases described. Use the information in the figure below to answer this question. Case B C Case Someone has recovered from an infection with measles virus and is now immune to the virus. Someone is vaccinated against poliovirus A newborn is immune to a disease that his mother had recovered from earlier. A patient is injected with immune serum to protect her against hepatitis B virus. Type of Acquired Immunity

What three specific cells chickenpox may encounter which are a part of the second line of defense? For these three cells discuss their function, how they can detect chickenpox, and what they do to remove the chickenpox.   (Discuss any receptors the immune cells have, chemical mediators, enzymes, etc. which are used to detect and remove the antigen.)

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)?

Discuss the processes of Humoral Immunity creating memory of an infection, including the definitions/ steps associated with Activation, Differentiation, and Proliferation as well as the two main cells (present during ALL stages) and their roles in the process.
