Antibodies not only play a major role in clinical diagnostics and biopharmaceutical analysis but also are class of drugs that regularly used to treat numerous diseases. The identification antibody-epitope binding sites is then great interest many emerging medical bioanalytical applications, particularly design monoclonal antibodies (mAb) mimics taking advantage amino acid residues involved the ...

The binding epitope structure of a protein specifically recognized by an antibody provides key information to prevent and treat diseases with therapeutic antibodies and to develop antibody-based diagnostics. Epitope structures of antigens can be effectively identified by the proteolytic epitope excision-mass spectrometry (MS) method, which involves (1) immobilization of monoclonal or polyclonal...

Under the heading of ‘Anti-CCP antibody-positive’, the first line should read ‘HLA-shared epitope-negative’, and the second line should read ‘HLA-shared epitope-positive’. Similarly, under the heading ‘Anti-CCP antibody-negative’, the first line should read ‘HLA-shared epitope-negative’ and the second line should read ‘HLA-shared epitope-positive’. The correct table is given here as Table 1 (a ...

The recognition of specific epitopes on allergens by antibodies and T cells is a key element in allergic processes. Analysis of epitope data may be of interest for basic immunopathology or for potential application in diagnostics or immunotherapy. The Immune Epitope Database (IEDB) is a freely available repository of epitope data from infectious disease agents, as well as epitopes defined for a...

OBJECTIVE To determine the predictive value of shared epitope alleles for response to treatment in patients with rheumatoid arthritis. METHODS Patients from our previously published triple DMARD study were tested for the presence of shared epitope alleles (DRB1 *0401, 0404/0408, 0405, 0101, 1001, and 1402). Patients who were shared epitope positive were then compared with those who were negat...

mutations in the human hepatitis b virus (hbv) genome contribute to its escape from host immune surveillance and result in persistent infections. the aim of this study was to characterize the molecular variations of the surface gene and protein in chronically-infected patients from the southern part of iran. the  surface  genes  from  12  hbv  chronic  carriers  were  amplified, sequenced  and ...

conclusions the results revealed that the novel multi-epitope dna construct could be an effective candidate in tuberculosis vaccine development, and it is qualified to investigate its potential to induce cd4 and cd8 t- cell immune response in the experimental animal model. results mhc class i-and class ii-predicted epitopes showed a high potential to binding to human hlas alleles, with global b...

background: vaccines capable of controlling tumor virus based infections are found difficult to develop due to the consistence latent infection in the host. dna vaccines are attractive tools for the development of hpv vaccines and inducing antigen-specific immunity owing to the stability, simplicity of delivery, safety and cost effectiveness. however, there is a need to increase their potency b...

We investigated the crystal structure of an HLA-A*2402-restricted CTL epitope in the HIV-1 nef gene (Nef134-10) before (pHLA) or after TCR docking. The wild type epitope and two escape mutants were included in the study. Y135F was an early-appearing major mutation, while F139L was a late-appearing mutation which was selected in the patients without Y135F. F139 was an eminent feature of the Nef1...
