IMMUNITY: Hello, I am trying to understand how our T and B cells have receptors for each specific antigen. How can there be a specific receptor for each antigen when there are so much different antigens? In a situation where a population is exposed to a new bacteria, how will their cells develop receptors specific for that new bacteria assuming that some of the population develops immunity and lives?

1. What is the role of primary lymphoid follicles in eliminating B cells that have antigen receptors specific for soluble self antigen?

2. What is "affinity maturation"? Affinity maturation of the B cell response has been likened to a process of "Darwinian selection". Explain how so?

3. If you could produce a strain of mice in which the follicular dendritic cells of the lymphoid organs were deleted, list the differences in the humoral immune response you might expect to see.

The pathologist examines the cells taken from the tumor, particularly the number of cells in mitosis. Below are the results. In normal breast cells, one would expect 0-4 cells per 10 high-powered field of view (microscopy) undergoing mitosis.

Based on the above results, what can you conclude about the tumor cells? Can you say definitively that they are cancerous? Be sure to support your answer with the data above.
