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.

What types of microbes do adaptive immune responses combat?
The adaptive immune system was developed in higher vertebrates to combat pathogens and antigens. These can include viruses, bacteria, and anything else that can cause the immune system to launch an immune response.
The foreign or nonself proteins that trigger immune responses are called?
An immune response is based on the ability to distinguish molecules that are part of the body ("self") from those that are not ("nonself," or foreign). Such molecules that can elicit an immune response are called antigens.
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 the introduction of altered antigens to produce an immune response?
vaccination
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
What is an excessive immune response to antigens?
Allergies
Macromolecules that induce the immune system to make certain responses?
antigens
What are Examples of inappropriate responses of the immune system?
Fever, Inflammatory myopathies, and vitamin A deficiency.
Is this true or false Allergies or hypersensitivities are normal immune responses?
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.

Why is an antigen important?
Antigens are important because they trigger responses to pathogens by the immune system. Without them, no prevention against pathogens would take place.
In order for antigens to incite the immune response they must be?
in order for antigens to incite the immune response the y must be ?
How does injecting an inactive form of pathogen make a person immune?
the inactive form still has the antigens (protein markers) specific to that pathogen on the surface. the immune system develops specific responses to this pathogen when it is encountered after a vaccination. as it is inactive the person does not suffer the effects of this pathogen, but when an active form is encountered later the immune system is quicker to respond due to the fact that it now recognises those antigens.
What are anitgens?
Antigens are respnses to immune responces.
What has the author Herman N Eisen written?
Herman N. Eisen has written: 'Immunology, an introduction to molecular and cellular principles of the immune responses' -- subject(s): Immunology, Antigens and antibodies, Immunity
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.
