Name 4 of the 7 ways antibody diversity is generated. 

Spleen cells are taken from a mouse immunized with the LCM virus.  2 assays are used to determine antigen-specific functional activity of the spleen cells.   Assay 1: the spleen cells (T cells) are incubated with macrophages that have been briefly exposed to LCM virus (phagocytized the virus), production of IL-2 by the T cells is considered a positive response. Assay 2: the spleen cells are incubated with LCM-infected target cells, lysis of the infected target cells is considered a positive response. Activity of which cell population is detected in Assay 2?

What is the difference between a primary immunodeficiency and acquired immunodeficiency?

What is a cytokine?

Do you inherit immunological memory?  What cells types are responsible for immunological memory?

How do natural killer cells recognize tumor infected cells?

Indicate which lymphocyte population you would expect to proliferate in each case:

Antigen presentation on the MHC – the exogenous pathway.  Is the antigen presented on MHC 1 or II?   Is the antigen presented to Tc cells or TH cells?

Indicate which type of hypersensitivity reaction (I-IV) apply to the following:
