Elements of Adaptive Immunity

Describe antigens and describe the characteristics of effective antigens. Identify, compare and contrast the three types of antigens.
How many kinds of MHCs are there? Where are they found? What is their function in the immune system?
Which cells are classified as APCs? What is an APC? What is its function in the immune system?
Explain how host cells know the difference between “self” and “non-self” cells when fighting infection.
Explain T cell clonal deletion and how it functions in autoimmune diseases. Describe clonal deletion of B cells and its purpose.
Describe what happens when a B cell is stimulated by the “right” antigen. Also, explain what a plasma cell is.
Describe what an antibody is, the general shape of an antibody, and identify where antigens bind to on an antibody.
Describe the five possible functions of antibodies.
Cell-Mediated Immune Responses

Describe the process of cytotoxic T cell activation during an immune response.
Antibody Immune Responses

Describe how memory B cells form and their role in immune defense.
Describe the difference of primary vs secondary immune response.
Chapter 23: Microbial Diseases of the Digestive System

For each of the diseases identified in this chapter:

identify the scientific name of the causative pathogenic organism
identify the type of organism (bacterium, fungus, virus, protozoan, helminth, prion, etc.)
identify the key signs & symptoms of the disease (especially those that differentiate it from other similar diseases)
describe differentiating features of the disease: pathogenesis of the disease including any common vectors, any common means of contraction, any individuals that are more likely to contract the disease, etc.
