Immunology T1C4

what is the eye of the pathogen?

epitope
what are the hallmark molecules of the adaptive immune system?
- antibody
- T-cell receptor
the antibody and T-cell receptor molecules are:

highly specific, recognizing the epitopes
what is an epitope?

the immunologically active regions of an immunogen (antigen)
epitopes binds to:
- antigen-specific membrane receptors on lymphocytes
- secreted antibodies in plasma
what is an antibody?

membrane bound constituents of B cells or soluble molecules secreted by plasma cells
members of the anitbody protein family have common stuctural features and are collectively known as:

immunoglobulin (Ig)
what is an antigen?
- molecules that interact with the immunoglobulin receptor of B cells
- interact with T cell receptor when complexes with MHC
- **nothing but a kind of pathogen
the ability to induce a humoral and/or cell-mediated immune response is

immunogenicity
the ability to combine specifically with the final products of the immune response (secreted antibodies and/or surface receptors on T cells) is

antigenicity
all immunogens are antigen but all antigens are NOT immunogens
haptens are antigenic but NOT

immunogenic
