When the immune system does not respond to a particular antigen?

Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.

What is the function of langerhan's cells?
Langerhans cells are a subset of dendritic cells that reside in the epidermis (Part of the immune system). They have long dendrites (like arms) that capture antigen in the skin, and when they find an antigen, they migrate to lymph nodes and present to T cells allowing the adaptive immune system to respond.
What is the molecule that can be recognized by the immune system?
Antigens.
Do vaccines tear down the immune system?
No, there is no proof of that. It is thought that vaccines are good for the function of the immune system because they give it "exercise"; or at least they are not bad for the immune system. Some believe that if the immune system isn't triggered to respond to an antigen periodically, it will not function as well when a real antigen invades the body, in sort of a "use it or lose it" way. That may not actually happen in the immune system, but many body systems and parts do work that way.

What does an antigen do?
An antigen is a foreign body. It is used as a "template" to begin an appropriate immune response.
What term describes the overaction of the body to a particular antigen?
Allergies develop when the body overreacts to an antigen.
What is antigene and antibody?
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
Are langerhan's cells epithelial cells?

All immunogen are antigen but all antigen are immunogen?
An Immunogen is foreign particle that triggers the body's immune system where as Antigen is also a foreign particle , due to its low molecular weight it is unable to trigger immune system. Example for antigen is Hapten
Why get vaccinated?
In short, a vaccination prevents you from catching a particular sickness. Vaccinations allow the immune system to become better prepared for a certain antigen (foreign invader) by giving it a "target" (usually a weaker or deaden strain of the antigen) to practice on. During the immune response to the vaccination, the body's supply of antibodies (and the B cells that produce it) is drastically increased. Should the vaccinated person encounter the antigen after vaccination, his/her immune system will be well prepared to put up a good fight. This is true for any effective vaccination against any antigen.
