The kind and characteristics of the syndrome present in the young boy who had a dozen of bacterial and viral infection in the past years. Introduction: The primary function of the immune system is to protect the body from foreign substances. However, various conditions may disturb the functioning of the immune system. The failure of the immune system may lead to the prevalence of the various viral and bacterial infection.

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)?
