Exam 17: Antibody-Immunity

For each of the functions described in questions ,select the complement system protein (A-F)that best matches it. -Produced by C3 convertases,this opsonin promotes phagocytosis of microbes.

Which of the following anatomic regions is normally protected from pathogens only by humoral immune responses and not by cell-mediated immune responses?

For each of the following descriptions in questions ,select the Fc receptor (A-G)that best matches it. -High-affinity Ig receptor on mast cells important in immediate hypersensitivity reactions

For each of the functions described in questions ,select the complement system protein (A-F)that best matches it. -This complement fragment is a component of the membrane attack complex.

For each of the following descriptions in questions ,select the Fc receptor (A-G)that best matches it. -Low-affinity Ig receptor on natural killer cells that mediates antibody-dependent cell-mediated cytotoxicity

For each of the following descriptions in questions ,select the Fc receptor (A-G)that best matches it. -High-affinity Ig receptor on macrophages and neutrophils important for phagocytosis and activation

For each of the functions described in questions ,select the complement system protein (A-F)that best matches it. -Generated by factor I-mediated proteolysis,this opsonizing complement fragment binds to CR3 on phagocytes.

For each of the functions described in questions ,select the complement system protein (A-F)that best matches it. -Generated by factor I-mediated proteolysis,this complement fragment binds to complement receptor 2 (CR2)on B cells and enhances B cell activation.

For each of the following descriptions in questions ,select the Fc receptor (A-G)that best matches it. -Ig receptor on B cells that mediates feedback inhibition

For each of the functions described in questions ,select the complement system protein (A-F)that best matches it. -This complement fragment is a chemoattractant for neutrophils.
