__________________________________________________ cells can help prevent autoimmune diseases. The antigen receptor on a B cell is essentially a membrane-bound ____________________________.  If a cell of yours lacks MHCs, ______________________________________  (specific kind of cell) might cause its death _________________________________ is the name of the migration activity by a neutrophil, e.g., when it is physiologically driven to move toward molecules at an area of injury. Its temporary binding and unbinding to sticky endothelial cell adhesion molecules on their way is called _______________________________________. When it enters the injured or infected tissue space from the capillary this is called ____________________________________. When identical plasma cells start being made, in great abundance, from a single specific immune cell, the originally chosen immune cell has undergone ______________________ - ______________________________________. What are a few things discussed…

Select the correct answer from the answers provided. The cross-linkage of antigens by antibodies is known as a. opsonization b. a cross-reaction c. agglutination d. complement fi xation

Match the type of lymphocyte cell with its main function in the immune system. Generates antibodies [ Choose] [Choose ] T cells Secretes cytokines Antibody B Cells NK cells Secretes cytotoxic granuales [ Choose ] Binds specific antigen [ Choose ]

NK Activity (% lysis) 100 80 40 20 O ooo O O BOQ 10 00 20 Depression O 30 p=0.0001 R=0.604 40 FIGURE 4 | Correlation between natural killer (NK) cell activity and depression. There is a significant correlation between NK activity and depression (p = 0.001; R = -0.604).

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)?
