what is the eye of the pathogen?
what are the hallmark molecules of the adaptive immune system?
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:
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
the ability to combine specifically with the final products of the immune response (secreted antibodies and/or surface receptors on T cells) is
all immunogens are antigen but all antigens are NOT immunogens
haptens are antigenic but NOT
