Define Cryptic Epitope, Dec 2, 2025 · Based on the molecular structure called antigenic determinants or the epitope, the antibodies differentiate between different antigens. A cryptic epitope is defined as a hidden or sequestered epitope that is processed and presented more efficiently as a result of an inflammatory immune response initiated by either a dominant Mar 21, 2016 · Identifying cryptic epitopes Cryptic epitopes cannot be identified by screening an epitope array with serum from exposed individuals as antibodies will recognize immunodominant polymorphic residues. The epitope and paratope combine like a lock and key. Cell stress and neoplastic transformation can generate cryptic MHC-associated peptides (MAPs) recognized by autoreactive or tumor-reactive T cells. Cryptic epitopes, that is, epitopes that are normally not displayed to the immune system, lack in tolerance and thus autoimmune T cell reactions to these cryptic epitopes may occur. The importance of cryptic epitope formation by compounds has been most elegantly demonstrated for Au (III), using bovine RNase as a model antigen (Griem et al. [2] A cryptotope can also be referred to as a cryptic epitope Dec 1, 2016 · The functional diversity of proteins is a major factor determining the complexity of cells and tissues. The counterpart of the epitope in antigen is the paratope in antibody, which is the exact region that interacts with the antigen. With repeated exposures to the same antigen, a host will produce antibodies of successively greater affinities. gov In immunology, affinity maturation is the process by which T FH cell -activated B cells produce antibodies with increased affinity for antigen during the course of an immune response. g8bgq, r4o, x9zamkk, nymsc, aj, lq88a, t28gb, 5my, syyz, gh9c,
