HIV vaccine candidates with improved immunogenicity and induction of mucosal T-cell immunity are needed. A prime-boost strategy using a novel HIV glycoprotein 120 DNA vaccine was employed to immunize rhesus macaques. The DNA vaccine encoded a chimeric gp120 protein in fusion with monocyte chemoattractant protein-3, which was hypothesized to improve the(More)
Cancer immune evasion is an emerging hallmark of disease progression. Functional studies to understand the role of myeloid-derived suppressor cells (MDSC) in the tumor microenvironment however, are limited by the lack of available specific cell surface markers. We adapted a competitive peptide phage display platform to identify candidate peptides binding(More)
Background The B cell receptor (BCR) expressed by a clonal B cell tumor is a tumor specific antigen (idiotype). However, the T cell epitopes within human BCRs which stimulate protective immunity still lack detailed characterization. Methods In this study, we identified 17 potential CD4 T cell peptide epitopes derived from BCR heavy and light chain variable(More)
