  2. Epitope - Wikipedia

    en.wikipedia.org/wiki/Epitope

    An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells. The part of an antibody that binds to the epitope is called a paratope .

  3. Idiotopes - Wikipedia

    en.wikipedia.org/wiki/Idiotopes

    In immunology, an idiotope is the unique set of antigenic determinants (epitopes) of the variable portion of an antibody. [1] In some cases it can be the actual antigen-binding site, and in some cases it may comprise variable region sequences outside of the antigen-binding site on the antibody itself.

  4. Linear epitope - Wikipedia

    en.wikipedia.org/wiki/Linear_epitope

    Recognition of epitopes in a linear fashion. Note: the same (colored) segment of protein can be a part of more than one epitopes. In immunology, a linear epitope (also sequential epitope) is an epitope—a binding site on an antigen—that is recognized by antibodies by its linear sequence of amino acids (i.e. primary structure).

  5. Major histocompatibility complex - Wikipedia

    en.wikipedia.org/wiki/Major_histocompatibility...

    The molecular region which binds to the epitope is the paratope. On surfaces of helper T cells are CD4 receptors, as well as TCRs. When a naive helper T cell's CD4 molecule docks to an APC's MHC class II molecule, its TCR can meet and bind the epitope coupled within the MHC class II. This event primes the naive T cell.

  6. Epitope mapping - Wikipedia

    en.wikipedia.org/wiki/Epitope_mapping

    In immunology, epitope mapping is the process of experimentally identifying the binding site, or epitope, of an antibody on its target antigen (usually, on a protein). [ 1 ] [ 2 ] [ 3 ] Identification and characterization of antibody binding sites aid in the discovery and development of new therapeutics , vaccines , and diagnostics .

  7. Polyclonal B cell response - Wikipedia

    en.wikipedia.org/wiki/Polyclonal_B_cell_response

    An epitope that can be attacked by many different B cells is said to be highly immunogenic. In these cases, the binding affinities for respective epitope-paratope pairs vary, with some B cell clones producing antibodies that bind strongly to the epitope, and others producing antibodies that bind weakly. [1]

  8. Idiotype - Wikipedia

    en.wikipedia.org/wiki/Idiotype

    The idiotype is based upon the variable region (labeled VL and VH in the diagram.) In immunology, an idiotype is a shared characteristic between a group of immunoglobulin or T-cell receptor (TCR) molecules based upon the antigen binding specificity and therefore structure of their variable region.

  9. Conformational epitope - Wikipedia

    en.wikipedia.org/wiki/Conformational_epitope

    Note how the segments widely separated in the primary structure have come in contact in the three-dimensional tertiary structure forming part of the same epitope [1] In immunology, a conformational epitope is a sequence of sub-units (usually amino acids) composing an antigen that come in direct contact with a receptor of the immune system.
