Question

Quizplus · Accepted Answer

Allergens cause an exaggerated immune response that results in allergy symptoms, even though they are generally harmless particles. Antigens, on the other hand, can be bacterial or viral in nature and stimulate the immune system to produce antibodies to fight off the foreign invader. Allergens are not restricted to plants and can be derived from other sources as well. Allergens do involve the activation of certain types of leukocytes, particularly mast cells and eosinophils, which are responsible for the inflammatory response.
