3. an adbantages to adaptive immunity is

a its memory cell that provide quicker larger and more efficient immune response upon second exposure to an antigen b its need for several cells to be activated over several days on first exposure c the ability for its individul cells to respond to many differnt pathogens d the use of antibodies that cause cells lysis and kill invading cells

4, an advantages of innate immunity is

a its a barrier taht prevent pathogens from entering into the body b the specifcity of its individual cell which specialize in the removal on one type of antigen c the numerous step in the activation of its cell that can prevent autoimmune disease d the use of the antibodies to cause cell lysis and kill invading cell

5. B- lymphocytes are categorized as part of the adaptive branch of the immune sys for all of the following reason but one Which of the following is NOT one part of reason B lyphocytes are considered part of the adaptive immunity?

a they produce memory cell when activated b their receptors will bind to only one antigen c they require costimulation from an activated T helper cell d thet are a first line of defense that can begin killing

6. Over lap in the innate and adaptive immune sys is seen in all of the following examples but one Which of the following examples does NOT illustrate the over lap of innate and adaptive immune resposes ??? a dendritic cell presenting antigen on their MHC II proteins to T helper cells b macrophage becoming activated macrophages in response to cytokines realesed by T helper cells c natural killer cell causing of an abnoraml host cell lacking MHC proteins d Plasma cell that produce large amounts of IgE that will ultimetly allow mast cell to relase histamine

7. Which of the following examples below describe an autoimmune disease? a infection and death of T helper cells bya virus resulting in a loss of adaptive immunity b realse of bacterial endotoxins that block acetylcholine realse result is muscle paralysis c antibody binding to acetylcholine receptors of hte motor end palte resulting in muscle weakness.d uncontrolled cell division resulting in cell surface abnormalities recognized by natural killer cell.

8. Which of he following does NOT describe actions of interferon IFN? a virally infected cell can release interferon which attracts natural killer cell to attack and kill the IFN secreting cell b IFN binds to normal uninfected cell stimulating the activation of genes that produce anti viral proteins c IFN will attract macrophages to the secreting cell to be removed bt phagocytosis d IFN can penetrate the virla capsid and destroy the virus

How did inoculation with cowpox generate immunological memory and provide protection against smallpox? Did cross-reactivity play a role?

How did Pasteurâs work with attenuated (weakened) bacteria further our understanding of the role vaccination can play?

What are the three characteristics that define an adaptive immune response? Briefly define each of the characteristics.

Define primary versus secondary immune response.

Whatâs the difference between totipotent, pluripotent, multipotent and oligopotent when evaluating cell differentiation capacity?

What is hematopoiesis?

What cell types are derived from myeloid versus lymphoid progenitor cells? Describe the function of each WBC type.

What is clonal selection?

What role do antibodies play with regard to antigen recognition and immune defense that is different from what Tcrs provide?

As described in class generally understand the outcome of B cell, Th cell, and Tc cell activation. Understand that these cells can differentiate into effector (plasma cells, cytokine producing Th cells and CTLs) or memory cells.

Understand how granzymes and perforins play a role in apoptosis.

Which types of cells typically express MHC Class II? Do these cell types also express MHC Class I, and if so why?

Be able to show cooperation between Tc, Th and B cell responses (refer to class notes).

What is the overall role of MHC Class I and II?

What is ADCC and what cell types are involved?
