The Cells and Signaling Molecules That Initiate Inflammatory Responses Are

Question

The cells and signaling molecules that initiate inflammatory responses are
A) the phagocytes and the lysozymes.
B) the phagocytes and the chemokines.
C) the dendritic cells and the interferons.
D) the mast cells and the histamines.
E) the lymphocytes and the interferons.

Accepted Answer

Mast cells are cells located in connective tissues that release histamines and other signaling molecules in response to injury or infection, initiating the inflammatory response. Therefore, D is the best choice as it correctly identifies the cells and signaling molecules involved in the initiation of the inflammatory response.
