Exam 7: Adaptive Immunity

Match the CD 4 (cluster of differentiation)cells and CD 8 cells with their characteristics.(Answers may be used more than once. ) -Recognize antigens presented by MHC II molecules

Increased age may cause which of these changes in lymphocyte function?

Which are characteristics of clonal selection?

Match each the helper T cell subset (Th1 or Th2)with its characteristics.(Th1 and Th2 can be used more than once. ) -Are induced by antigens derived from cancer cells

While macrophages present processed antigens to memory Th cells,B lymphocytes present antigens to helper Th cells.

Match the CD 4 (cluster of differentiation)cells and CD 8 cells with their characteristics.(Answers may be used more than once. ) -Recognize antigens presented by endogenous protein molecules

What type of immunity is produced when an immunoglobulin crosses the placenta?

Match the CD 4 (cluster of differentiation)cells and CD 8 cells with their characteristics.(Answers may be used more than once. ) -Recognize antigens presented by exogenous protein molecules

Why are some viruses,such as measles and herpes,inaccessible to antibodies after the initial infection?

Where are antibodies produced?

MATCHING Match each immunoglobulin with its characteristic or function.(Immunoglobulins can be used more than once. ) -Mediates many common allergic responses

Match the CD 4 (cluster of differentiation)cells and CD 8 cells with their characteristics.(Answers may be used more than once. ) -Develop into helper T cells

Most antigens react directly with cells of the immune system.

During which phase of life does the generation of clonal diversity occur?

What are characteristics of helper T1 cells (Th1)?

When antigens are administered to patients to produce immunity,why are different routes of administration used (e.g. ,some are given intravenously,whereas others are given subcutaneously or nasally)?

MATCHING Match each immunoglobulin with its characteristic or function.(Immunoglobulins can be used more than once. ) -Synthesized early in neonatal life

When a person is exposed to most antigens,how long does it take before an antibody can be detected in the circulation?

Helper T 2 cells (Th2)produce interleukin 4 (Il-4)that suppresses which lymphocytes?

How is the function of the B-cell receptor (BCR)complex different from the function of circulating antibodies?
