An immune response is part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically toward that pathogen.
Allergies cause the immune system to react abnormally to the allergen that has entered the body. One of the more common allergies is pollen. When this allergen has entered the body, The immune system will attack it. Even though pollen is harmless, your immune system sometimes may think that a pathogen (germ) has entered the body, therefore causing the body to produce histamine. Your doctor will give you antihistamines if you are allergic to something. Antihistamines will stop symptoms such as a runny-nose, watery eyes and itchy eyes.
Epilepsy is not an infection or a virus or anything like that, so the immune system is not relevant to it. You cannot "catch" epilepsy from someone. So the immune system does not respond to epilepsy. There is nothing that it can do.
Response cells are cells that respond to the immune system and react to diseases.
The first defense is nonspecific.
No, there are no healing properties in a dog's saliva. Allergies are caused by the body's immune system reacting inappropriately to a neutral protein molecule and treatment is based upon controlling the reaction in acute cases and retraining the immune system to not react in the long term. Exposure to a dog's saliva does neither of these, and may make allergies worse by stimulating the immune system to react to the saliva as well as whatever else it was reacting to.
A vaccine normally exposes the body's immune system to dead portions of the virus it is trying to protect against. The immune system will still react to the dead virus and develop anti-bodies to protect against the virus. This will either prevent the person from becoming infected or reduce the length and the severity of the symptoms if they do become infected.
the immune system produces immune cells in response to the presence of early cancer cells which cross-react with the calcium channels on nerve cells
Hives are the result of an immune system overreacting to an allergen. For example, some people have no problem with penicillin as a medication, but other people react to penicillin, breaking out in hives. The immune system attacks the penicillin, treating it as a foreign substance... which is technically correct, but it isn't the reaction that we necessarily want.
No, they react similarly to a human.
The immune system responds to a bacterial infection in various ways. In most cases, it will release antibodies which will attempt to fight the infection in various ways.
The complement system is made up of a large number of plasma proteins. They react with one another to opsonize pathogens and induce a series of inflammatory responses that help to fight infection.
