Which of the following play the greatest role in anaphylactic reactions?
a) Lymphocytes
b) Erythrocytes
c) Histiocytes
d) Eosinophils
e) Dust cells
Click for Answer
Answer
Answer a. Anaphylaxis is mediated by IgE, which is produced by lymphocytes. In addition, histamine and several arachidonic acid metabolites are implicated in anaphylaxis; these are released by tissue mast cells and (to a lesser extent) circulating basophils. Eosinophils target primarily parasites; histiocytes and dust cells are both tissue-bound cells in the monocyte-macrophage lineage.
