Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...
Objective(s):Human Cytomegalovirus (HCMV) remains a major morbidity and mortality cause in immuno suppressed patients. Therefore, significant effort has been made towards the development of a vaccine. In this study, the expression of the pp65 and gB fusion peptides and Fc domain of mouse IgG2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (APCs) in Pich...

memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. the main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. mice were immunized with human immunodeficiency virus-1 p24-nef fusion peptide and then cellular and humoral immune responses were evaluated. in order to determin...
objective: several vaccines against hiv have been investigated but none has been approved as an effective hiv vaccine. an approach that could induce stronger immune response against the pathogen is utilizing a multi-epitopic vaccine. this strategy was used in the design of several vaccines and resulted in improved immune responses. materials and methods: in this study a multi-epitopic fusion p...
Objective(s):Tumor-associated antigen (TAA) subunit-based vaccines constitute promising tools for anticancer immunotherapy. However, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.The aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic HER2/neu derived pept...
Background: Hepatitis C virus (HCV) causes acute and chronic human hepatitis infections. Due to the high genetic diversity and high rates of mutations in the genetic material so far there is no approved vaccine against HCV. Materials and Methods: The aim of this study was to determination B and T cell conserved epitopes of E1 and E2 proteins from HCV and construction of a chimeric pepti...
Foot and Mouth Disease (FMD) is highly contagious disease among cloven-hoofed animals. FMD virus has structural and non-structural proteins. Vp1 is the most immunogenic structural peptides of FMD virus, applied for major vaccine studies. Objective: Construction of Pet28-VP1 cassette for FMD virus type O/IRN/2010 and expression VP1 peptide as the most immunogenic antigen was the aim of this stud...
Introduction: Influenza A virus causes unpredictable epidemics and pandemics by creating antigenic variations. With the appearance of each new strain, rapid emergency countermeasures are taken against this new strain. Hence, designing an applicable and cross protective strategy to counter this virus is of great importance. To achieve this, choosing conserved antigenic regions in influenza virus...
foot and mouth disease (fmd) is highly contagious disease among cloven-hoofed animals. fmd virus has structural and non-structural proteins. vp1 is the most immunogenic structural peptides of fmd virus, applied for major vaccine studies. objective: construction of pet28-vp1 cassette for fmd virus type o/irn/2010 and expression vp1 peptide as the most immunogenic antigen was the aim of this stud...
