Murine monoclonal antibodies to Campylobacter jejuni recognized a flagellin epitope common to most Campylobacter species and an epitope restricted to C. jejuni and C. coli. These epitopes are distinct from the serotype-specific epitope recently detected on the flagellin and have not been described previously.

RNA viruses undergo rapid sequence variation as the result of error-prone RNA replication mechanisms. When viable mutations arise in RNA regions encoding B or T cell epitopes, mutant viruses that can evade immune detection may be selected. In the carefully studied CTL response to the Gag p11C(C-M) epitope in SIVmac-infected Mamu-A*01(+) rhesus monkeys, it has been shown that CTL recognition of ...

Current tests for antibodies specific the SARS-CoV-2 S protein say nothing about their precise epitope specificities. These data are needed to properly assess immune status of individuals following infection or vaccination, and risk posed by virus variants.

Despite recent advances in therapeutic options, hepatitis C virus (HCV) remains a severe global disease burden, and a vaccine can substantially reduce its incidence. Due to its extremely high sequence variability, HCV can readily escape the immune response; thus, an effective vaccine must target conserved, functionally important epitopes. Using the structure of a broadly neutralizing antibody i...

UNLABELLED The hepatitis C virus (HCV) E2 envelope glycoprotein is crucial for virus entry into hepatocytes. A conserved region of E2 encompassing amino acids 412 to 423 (epitope I) and containing Trp420, a residue critical for virus entry, is recognized by several broadly neutralizing antibodies. Peptides embodying this epitope I sequence adopt a β-hairpin conformation when bound to neutralizi...

Several recent large clinical trials evaluated HIV vaccine candidates that were based on recombinant adenovirus serotype 5 (rAd-5) vectors expressing HIV-derived antigens. These vaccines primarily elicited T-cell responses, which are known to be critical for controlling HIV infection. In the current study, we present a meta-analysis of epitope mapping data from 177 participants in three clinica...

The HNK-1 epitope has a unique structure comprising the sulfated trisaccharide (HSO(3)-3GlcAbeta1-3Galbeta1-4GlcNAc), and two glucuronyltransferases (GlcAT-P and GlcAT-S) are key enzymes for its biosynthesis. However, the different functional roles of these enzymes in its biosynthesis remain unclear. Recently, we reported that a nonsulfated form of this epitope, which is biosynthesized by GlcAT...

The gamma-aminobutyrate-synthesizing enzyme glutamate decarboxylase (GAD; L-glutamate 1-carboxy-lyase, EC 4.1.1.15) is a major target of autoantibodies associated with both early and late stages of pancreatic beta-cell destruction and development of type 1 diabetes. We have used five monoclonal anti-islet-cell antibodies (MICAs 1,2,3,4, and 6) derived from a newly diagnosed diabetic patient to ...

The data information provided in this article relate to our research article "Using patient serum to epitope map soybean glycinins reveals common epitopes shared with many legumes and tree nuts" (Saeed et al., 2016) [1]. Here we provide western blot detection of glycinin subunits by soy-sensitive human sera, ELISA screens with overlapping synthetic peptides (epitope mapping), and various databa...
