human cytomegalovirus is one of the most common pathogenic viruses all over the world. in congenital infection leads to neurologic severe disorders and even death of fetus and in individuals with immunosuppression may also cause severe clinical symptoms. multiple evidence indicate that among several strategies, epitope-based vaccine (evs) that can induce both humoral and cellular immunity respo...

objective(s):brucellosis, especially caused by brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500,000 human cases reported annually. the commonly used live attenuated vaccine in ovine brucellosis prophylaxis is b. melitensis rev1. but due to different problems caused by the administration of this vaccine, a protective subunit vaccine against b. me...

conclusions the distribution of amino acid mutations as well as the ratio between missense and silent nucleotide mutations (dn/ds) showed that a narrowly focused immune pressure had already been on the surface protein (especially ctl epitopes) which led to the emergence of escape mutants in these patients who were in tolerance phase of chronicity. materials and methods the surface genes from 17...

BACKGROUND Epitopes of human leukocyte antigen (HLA) are the sites to which the antibodies bind. We identify here 103 HLA class I epitopes shared by groups of class I antigens. In particular, our emphasis was on identifying epitopes exclusive to the C-locus antigens or interlocus epitopes among A, B, and C antigens. The use of monoclonal antibodies or alloantibodies eluted from HLA recombinant ...

Adaptive immune responses associated with allergic reactions recognize antigens from a broad spectrum of plants and animals. Herein a meta-analysis was performed on allergy-related data from the immune epitope database (IEDB) to provide a current inventory and highlight knowledge gaps and areas for future work. The analysis identified over 4,500 allergy-related epitopes derived from 270 differe...

House dust mite (HDM) allergy is the leading cause of IgE-mediated hypersensitivity. Therefore identifying potential epitopes in the Dermatophagoide pteronyssinus 23 (Der p 23), a major house dust mite allergen will aid in the development of therapeutic vaccines and diagnostic kits for HDM allergy. Experimental methods of epitope discovery have been widely exploited for the mapping of potential...

The 3-dimensional structure of an allergen defines the accessible parts on the surface of the molecule or epitopes that interact with antibodies. Mapping the antigenic determinants for IgE antibody binding has been pursued through strategies based on the use of overlapping synthetic peptides, recombinant allergenic fragments or unfolded allergens. These approaches led to the identification of m...

The dengue virus (DENV) nonstructural protein 1 (NS1) is an immunogenic protein that holds potential for the development of vaccines and diagnostic reagents; however, the epitopes of NS1 have not been comprehensively mapped. We mapped B-cell linear epitopes on NS1 using 149 monoclonal antibodies with DENV serotype specificity and cross-reactivity as well as antisera from 27 mice immunized with ...

Characterizing B-cell epitopes is a fundamental step for understanding the immunological basis of bio-recognition. To date, epitope analyses have either been based on limited structural data, or sequence data alone. In this study, our null hypothesis was that the surface of the antigen is homogeneously antigenic. To test this hypothesis, a large dataset of antibody-antigen complex structures, t...
