Exam 13: Effector Mechanisms of Humoral 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.

Matching 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. -Generated by factor I-mediated proteolysis, this complement fragment binds to complement receptor 2 (CR2) on B cells and enhances B cell activation.

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

Matching 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

Matching 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.

Matching 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. -This complement fragment is a component of the membrane attack complex.
