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...

Despite widespread uses of tetanus toxoid (TT) as a vaccine, model antigen and protein carrier, TT epitopes have been poorly characterized. Herein we defined the human CD4+ T cell epitope repertoire by reevaluation of previously described epitopes and evaluation of those derived from prediction of HLA Class II binding. Forty-seven epitopes were identified following in vitro TT stimulation, with...

Cytotoxic T lymphocyte (CTL) epitopes are potential candidates for subunit vaccine design for various diseases. Most of the existing T cell epitope prediction methods are indirect methods that predict MHC class I binders instead of CTL epitopes. In this study, a systematic attempt has been made to develop a direct method for predicting CTL epitopes from an antigenic sequence. This method is bas...

Viruses employ various modes to evade immune detection. Two possible evasion modes are a reduction of the number of epitopes presented and the mimicry of host epitopes. The immune evasion efforts are not uniform among viral proteins. The number of epitopes in a given viral protein and the similarity of the epitopes to host peptides can be used as a measure of the viral attempts to hide this pro...

Conformational epitopes are thought to form the majority of strong antibody binding epitopes on most proteins. However numerous conformational epitopes may also be recognizable as linear epitopes, although with lower affinity. Linear B cell epitopes typically vary from 5 to 20 amino acids in length. If the antibody-binding region of the protein is unknown, an overlapping peptide library can be ...

For development of effective vaccines against viruses, it is of importance to choose appropriate epitopes as the target for immunization. These epitopes should eventually be determined experimentally, but it would be helpful if we could predict candidate epitopes computationally because it accelerates the entire process. To predict candidate epitopes for immunization, it is of great interest to...

Cellular immune responses mediated by CD8+ cytotoxic T-lymphocytes (CTL) and CD4+ helper T-lymphocytes (HTL) are needed to effectively control and clear many viral pathogens, including HIV-1. Thus, vaccines for HIV-1 capable of inducing CTL and HTL responses are now the focus of multiple academic and industry-based research and development programs. The use of defined, minimal CTL and HTL epito...

Cytotoxic T lymphocytes (CTL) play an important role in the control and elimination of infection by West Nile virus (WNV), yet the class I human leukocyte antigen (HLA)-presented peptide epitopes that enable CTL recognition of WNV-infected cells remain uncharacterized. The goals of this work were first to discover the peptide epitopes that distinguish the class I HLA of WNV-infected cells and t...

Babesia bovis merozoites are exposed to antibodies during the extraerythrocytic phase, and surface polypeptides bearing exposed epitopes are possible immunogens. Monoclonal antibodies reactive with the merozoite surface bind either immunodominant epitopes expressed diffusely on the merozoite surface or, alternatively, epitopes expressed in a polar pattern. Epitopes expressed diffusely on the im...
