56. Tumour necrosis factor (TNF) is a protein that can be released by several types of cell. It plays an important part in the immune response. This protein binds to specific receptors on the surface of cell membranes stimulating chemical reactions inside the cell. As a result, a number of responses may occur that include inflammation and the stimulation of phagocytosis by macrophages. Antibodies to TNF are used to treat rheumatoid arthritis. According to the text, why are antibodies to TNF used to treat rheumatoid arthritis?
(A) They increase TNF-induced phagocytosis by macrophages.
(B) They promote the release of TNF to strengthen the immune response.
(C) They reduce inflammation caused by TNF activity.
(D) They block TNF receptors on cell membranes.
(E) They decrease the risk of bacterial infections in joints.
