QUIZ QUESTION: In an example of inflammation-mediated antibody damage to cells, Ig binds to self antigen on epithelial cells → complement binds Ig and is activated → pro inflammatory fragments of complement proteins are produced → the fragments bind to vessel walls → neutrophils move out of vessels → neutrophils bind to ____________ via receptors → neutrophils are triggered to release granules that damage cells. 1. complement proteins 2. Ig Fc portion 3. infected cells 4. sel...

What must an effective immune response do? (4 things) ~~> Be able to recognise and respond to invading pathogen Not over-react to to benign or self Be able to direct different effector mechanisms against different pathogens Links innate and adaptive responses What is adaptive immunity? (3 details) ~~> It is induced by exposure to a PARTICULAR infection, it has a high degree of specificity. It exhibits memory What is the clonal selection theory? Why? 2 | P a g e | © copyright ...

Are B and T lymphocytes part of the adaptive or innate immune response? ~~> Adaptive it is the immune memory evolved over time What is the clonal selection theory? ~~> Immature lymphocytes that could self find are destroyed Mature naive lymphocytes are mature until they are exposed to antigens What are the two types of B receptor? ~~> Membrane bound And released from membrane they are known as antibodies T cell receptors are only membrane bound and are formed of what hete...
