Usually a virus that hides inside a host cell where it is undetectable (the majority of the time) its antigens wouldn't always be presented on the surface of the cell for macrophages to engulf =]

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 molecule that can be recognized by the immune system?
Antigens.
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.
What term describes the overaction of the body to a particular antigen?
Allergies develop when the body overreacts to an antigen.
What does an antigen do?
An antigen is a foreign body. It is used as a "template" to begin an appropriate immune response.
What causes the immune response?
an antigen
What is a substance that causes an immune response called?
Antigen
Is the immune response triggered by antibodies?
No. Immune response is triggered by the antigen.
What is the first step of the immune response?
antigen
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.
What is the function of an antigen in an antigen-antibody response?
To help immune cells identify and destroy a pathogen
