Which of the Following is True of Activation of Mast

Question

Which of the following is true of activation of mast cells?
A) Causes the release of epinephrine
B) Is necessary for T-cell activation
C) Prevents the development of anaphylaxis
D) Causes the release of histamine

Accepted Answer

Activation of mast cells causes the release of histamine, which plays a key role in the inflammatory response and can lead to symptoms of allergy and asthma. Mast cell activation can be triggered by allergens, pathogens, or other stimuli, and can lead to the recruitment of immune cells and amplification of the immune response. Mast cells do not release epinephrine, are not necessary for T-cell activation, and do not prevent anaphylaxis.
