An antigen is called an allergen when it triggers an abnormal immune response that leads to allergic reactions in sensitive individuals. This typically occurs when the immune system mistakenly identifies a harmless substance, such as pollen, pet dander, or certain foods, as a threat. The ensuing immune response can cause symptoms ranging from mild (like sneezing or itching) to severe (such as anaphylaxis). Essentially, allergens provoke an exaggerated response from the immune system, distinguishing them from other antigens that do not elicit such reactions.

What is a substance that causes an immune response called?
Antigen
Is an allergen a antigen?
NO
Is an allergen an antigen?
NO
What is a substance that induces an immune response?
This substance has a general name called an antigen.
The initial exposure to an antigen is called?
Some more context would be helpful. This question sounds like it may be asking about antigen exposure in the field of allergic disease, but it's hard to be sure. Hypersensitivity reactions (the immune system basis for allergies) are based on the principle that allergy follows initial sensitization to an antigen.
What is the chemical called that causes an allergic response?
It's general biochemical name is an Antigen - anti = against and gen = genesis.
How is histamine related to allergies?
An allergy is a hypersensitivity to an environmental antigen (allergen). If a person has a hypersensitivity to an antigen they will have a patholigic (disease) response when exposed to that antigen. When the hypersensitive individual is initially exposed to the antigen, they will produce allergen specific antibodies, primarily immunoglobulin E (IgE), that will during subsequent exposures bond with membrane proteins on the mast cell membrane. This bonding allows degranulation (the release of stored chemicals) of the mast cell. Mast cells manufacture and store chemicals, including histamine, that are responsible for the affects of inflamation.
What antibody is produced in a reaction to an allergen?
The antibody is specific to the antigen (allergen). Different antibodies are produced at different times of exposure (IgM=acute; IgG=longterm) or in different systems of the body (IgA is produced in the gut).
What is the protein made in a response to a specific antigen called?
An antigen is a protein made in response to a specific antigen.
Why is DPT called triple antigen?
DPT is called triple antigen DPT means depthirian petanues tetanus
What is the foreign material called that stimulates the production of an antibody?
do you mean antigens? An antigen is any (foreign) substance that stimulates an immune reaction.
What is the process by which an antibody binds to an antigen?
The process by which an antibody binds to an antigen is called antigen-antibody binding. This occurs when the antibody recognizes and attaches to a specific part of the antigen, forming a complex that helps the immune system identify and neutralize the antigen.
