Antigens are recognized by antigen receptors, including antibodies and T-cell receptors. [3] Diverse antigen receptors are made by cells of the immune system so that each cell has a specificity for a single antigen. [3]
An antigen is a large protein molecule capable of inducing an immune response in the body by the production of antibodies. Explore its types, properties and structure at BYJU'S.
Jun 1, 2024 · Antigen, substance that is capable of stimulating an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cells. In general, two main divisions of antigens are recognized: foreign antigens (or heteroantigens) and autoantigens (or self-antigens).

Mar 30, 2023 · Antigens are molecules or molecular structures that are foreign to the body and generally induce an immune reaction in the form of the production of antibodies against them. In simple words, antigens can be anything that doesn’t belong to the body and are foreign.
Jan 16, 2024 · An antigen is a molecule that may be recognized by the immune system and trigger an immune response by activating leukocytes (white blood cells) that fight disease.
Oct 25, 2023 · An antigen is a molecule or particle, often found on the surface of cells, viruses, or bacteria, that triggers an immune response because the body recognizes it as foreign or non-self. The term “antigen” is a shortened term for ANTI body GEN erating substance.
