Explanation:
Detailed explanation-1: -Any substance which is recognized by the immune system is an antigen. In the case of people with allergies, the allergens are picked up by certain cells, called antigen-presenting cells, which process them and allow them to be recognized by and to alert the innate immune system to their presence.
Detailed explanation-2: -If you are insect-allergic, after the first sting, your body produces antibodies called Immunoglobulin E (IgE). If stung again by the same kind of insect, the venom interacts with this specific IgE antibody, triggering the release of substances that cause an allergic reaction.
