Antigens.
An antigen is a foreign body. It is used as a "template" to begin an appropriate immune response.
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.
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
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.
antibodies are immune cells which are present in the immune system and it helps in , if any foregin particles or antigens enters in our body it kills that antigen or it binds to the antigen and forms the antigen _antibody complex

The medical term for a foreign substance is "antigen." An antigen is any substance that the immune system identifies as foreign and triggers an immune response.
Antigens are majorly organic molecules which are not familiar to the organism itself. and starts immune response.
No. Hapten is an antigen whic has low molecular weight and does not trigger immune system.
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.
