Give a brief overview about the components of both innate and adaptive immunity. In addition to this overview, then compare and contrast innate vs adaptive immunity. Include at least 3 similarities (compare) and 3 differences (contrast)

A two-month-old baby is found to lack class I MHC molecules. How would this defect impact his adaptive immune response? Include answers to the following points: • What is the function of MHC I molecules in the adaptive immune response? • Will the entire adaptive immune response be impacted or only part of it? Please explain. • What type of infections will be impossible to tackle without MHC I molecules?

Based on your understanding of the innate immune system list 3 broad categories (and AT LEAST ONE specific example in each category) that constitute the first line of defense mechanisms by the innate immune system. (Give an approximate time line for this type of defense)   If this defense system is breached describe the process that follows (second line of innate defense). Explain how pathogens are detected and dealt with at this time with specific pathogen groups in mind, innate immune cells and molecular components involved. (Give an approximate timeline for this response)   What are the TWO possible outcomes of this response and the way forward?

Using complete sentences, compare and contrast the of the innate and adaptive immune systems with the following considerations: What are each system’s functions? Which cells are involved in each? What outcomes occur afteractivation?

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)?
