Chapter 16: The adaptive immune response
The strategic placement of these lymphoid structures makes it possible for the adaptive immune system to deal with potential pathogens from almost any place that is involved in infection.
Any nucleated cell
Ag presenting cell
Note: antigen and antigen receptor are omitted.
A newborn baby has a rash and organ anomalies. You determine antibody titers against rubella. Which of the following results from the baby’s serum suggests that the baby had an intrauterine infection with rubella?
IgE (important for parasitic infections)
Specific antigen recognition
Clonal selection and deletion are processes that allow some lymphocytes to mature while others are deleted from the body.
T cells are initially naive and become armed effector cells after encountering their specific antigen.
Antigen presentation involves combining antigen with class II MHC molecules.
CD4 helper T cells recognize class II MHC molecules, whereas CD8 cytotoxic T cells recognize class I MHC molecules.
B cells are responsible for antibody production. B cells differentiate into plasma cells that produce antibody.
There are five types of antibody molecule: IgG, IgM, IgA, IgD, and IgE.
T cells direct the production of antibody.
CD8 cytotoxic T cells kill specifically identified targets and remember them through the development of memory cells.
CD4 helper T cells can be divided into two groups, Th1 and Th2, each with a different helper function.
The adaptive immune response can be divided into a primary phase and a secondary phase.
