They're abnormal immune responses - by definition, an allergy is an inappropriate response to a foreign substance. After all, it's not known as an 'allergy' when people's immune systems attack harmful pathogens, despite the body mounting somewhat similar immune responses.

Inappropriate or excessive immune responses to antigens are?
There are four different types of hypersensitivities. Type I Hypersensitivities are mostly allergies and they are exaggerated, misdirected expression of immune responses to an allergen (antigen). The severity of allergies can range from atopy (local allergy such as hay fever or asthma) or anaphylaxis (a violent and potentially fatal reaction that leads to narrowing of the bronchial airways). Foods, drugs, pollen and bee stings can trigger these reactions and this kind of sensitivity can be transferable to normal people through serum antibody.
Which T cell inhibits the activity of other T cells?
Regulatory T cells (Treg) suppress the action of other T cells. This inhibits immune responses to self-antigens, aiming to prevent the immune system from attacking normal self cells.
What is immunology in animal practice?
Immunology is the study of the immune system and applies to animals the same way as it does to humans. Animals can have allergies, autoimmune disorders (arthritis, depressed immune systems, etc.) that need to be treated so that the animal can live a more normal life.
Does Autoimmune mean your immune system can catch many of the diseases like flu and cold germs more easily?
No. Autoimmune disorders are those in which your bodies immune system recognizes a certain type of your own tissue as foreign tissue and activates an immune response to destroy what it believes foreign. Your regular immune responses are still functional to fight normal infection.
Are reflex actions quicker than normal responses?

What characteristics does a normal immune complex test have?
Normally, immune complexes are not detected in the blood.
How allergy shots would help a person with allergies?
A person with allergies is generally understood to have an immune system that over-reacts to normal and inocuous materials, such as pollen. The "allergy shot" is an injected solution containing a very dilute and small amount of these materials. The idea behind allergy shots is to continuously expose the immune system to very low levels of the material so that the immune system learns to "tolerate" the material and the person will stop having allergy symptoms. Generally the person will need to be on allergy shots for the rest of his/her life - without constant low-level stimulation, the immune system tends to lose its tolerance and the allergy symptoms return.
Can seasonal allergies cause skin rashes?
Yes, seasonal allergies are no different from 'normal' allergies.
What is the pronosis for allergies?
Allergies can improve over time, although they often worsen.Learning to recognize and avoid allergy-provoking situations allows most people with allergies to lead normal lives.
Is it normal to have a headache when your allergies are bothering you?
Headaches can happen anytime during whole day or night. So it can happen during allergies too.
What is an an allergy?
Allergy - heightened sensitivity to the effects of some body of environmental factors, known as allergens.The cause of allergiesis the impact on the body of allergy. This may be not only drugs but also food, household dust, animal hair, pollen plants, household chemicals, cosmetics, cold, sunshine and much more. Will there be a man or not allergy, rooted in heredity. If one parent suffers from allergies, the probability of its occurrence in the child - 30%. Contribute to the development of allergies psychic and emotional overload, hypodynamia, poor nutrition. Someone would need allergies if that person had a weak and vulnerable immune system. Without allergies, those of us with helpless immune systems would be ill forever. Therefore, an allergy is like added protection for the immune system.
Do antigens cause normal immune response?
No. Hapten is an antigen whic has low molecular weight and does not trigger immune system.
