A 48-year-old patient suffering from multiple sclerosis is receiving interferon injections. The purpose of interferon injections is to:
A) Modify the immune response by suppressing antibody production and cellular immunity
B) Give rise to numerous cell types able to form tissues in three germ layers
C) Complement receptors and, as a result, play an important role in the clearance of antigens
D) Complement components, prostaglandins, leukotrienes, and other inflammatory mediators
Ans: A
Feedback: Interferons are thought to modify the immune response by suppressing antibody production and cellular immunity. The red blood cells and platelets also have a role in the immune response. Red blood cells and platelets have complement receptors and, as a result, play an important role in the clearance of immune complexes that consist of antigen, antibody, and components of the complement system. Embryonic stem cells have pluripotent capacity and give rise to numerous cell types able to form tissues of all three germ layers. Complement components, prostaglandins, leukotrienes, and other inflammatory mediators all contribute to the immune response.
