What else can I help you with?
What is the term used to describe if a patient has ever had contact with a particular antigen?
The term used to describe if a patient has ever had contact with a particular antigen is "sensitization." Sensitization occurs when the immune system has been exposed to and recognized a specific antigen, leading to an immune response upon subsequent contact with the same antigen.
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 system does antigen belong to?
Antigen is a component of the immune system. It can trigger an immune response in the body by interacting with antibodies or immune cells.
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 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.
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
What is the blood cell protein that elicits an immune reaction?
The protein that elicits an immune reaction in blood cells is called an antigen. Antigens are typically foreign substances that trigger an immune response when they are detected by the immune system.
