Question

Quizplus · Accepted Answer

Neutrophils are not involved in IgE mediated hypersensitivity. The process involves an antigen presenting cell presenting the antigen to a B cell, which produces IgE antibodies. The IgE antibodies then bind to mast cells. Upon re-exposure to the antigen, the antigen binds to the IgE antibodies, causing the mast cells to release histamines and other mediators that cause an allergic reaction.
