Journal Article (Journal Article) An immune correlates analysis of the RV144 HIV-1 vaccine trial revealed that antibody responses to the gp120 V1/V2 region correlated inversely with infection risk. The antigenicity, immunogenicity, function, and subcellular localization of these proteins including merozoite surface protein 1 paralog (MSP1P) [3,4], Pv41 , PvMSP10 , Pv12 , and RhopH2 were also evaluated. Immunogenicity, effectiveness, and efficacy have been evaluated in children and adults. The results of this analysis revealed that, al- though suboptimal for binding to the HLA-A*0201 mole- cule, peptide NY-ESO-1 157-165 is, among natural se- Each focuses ∼80% of the response on hemagglutinin (HA), mainly through recognition of the major antigenic sites in the HA globular head domain.

We studied the antigenicity and immunogenicity of EBOV GP with mutations in N-linked glycosylation sites or deletions in the mucin region. The antigenicity of the 5 and 20 μM kifunensin-treated gp120 Ba-L was probed with mAbs, sCD4 and a recombinant immunoglobulin-CD4 chimeric protein expressing 4 gp120 binding sites, CD4-IgG2 51: very similar results were obtained for both and so only the 5 μM data are shown . With the realization HLA antibodies recognize epitopes rather than antigens, it has become apparent that donor-recipient compatibility should be assessed at the epitope level. Such a 'deimmunization' process has been investigated for CD22- and CD25-targeted, cytotoxic immunotoxins, with evidence of reduced antigenicity and immunogenicity in experimental models and in patients with hairy-cell leukemia [69, 70]. Two key determinants of tumor immunogenicity are tumor antigenicity and the ability to present such antigenicity.

Immunogenicity and antigenicity of the recombinant EMA-1 protein of Theileria equi expressed in the yeast Pichia pastoris. We are unable to test the immunogenicity of HA22-LR-LO10 in humans so instead we assessed its antigenicity; that is, the binding of HA22-LR-LO10 to preexisting antibodies made against native RIT, as a surrogate measure of the immune response . These two terms are related to antigen which can be confusing sometimes.
