Question

Quizplus · Accepted Answer

An allergic reaction can trigger the release of histamine, which produces allergy symptoms such as itching, swelling, and inflammation. Histamine is released by immune cells called mast cells, which are activated during an allergic reaction. Antihistamines can help relieve allergy symptoms by blocking the effects of histamine. Antibodies and antivirals are not directly involved in producing allergy symptoms.
