Background Cystic echinococcosis (CE), as a zoonotic disease cause to health threat and economic losses. Despite implemented control programs, few countries have been able to decrease or eliminate this infection. Vaccination of the intermediate host offers an additional strategy to control the parasite transmission and EG95 antigen is considered more than the others in the vaccine issue. Accord...

BACKGROUND Botulinum neurotoxin (BoNT) complexes consist of neurotoxin and neurotoxin-associated proteins. Hemagglutinin-33 (HA-33) is a member of BoNT type A (BoNT/A) complex. Considering the protective role of HA-33 in preservation of BoNT/A in gastrointestinal harsh conditions and also its adjuvant role, recombinant production of this protein is favorable. Thus in this study, HA-33 was expre...

objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...

Background and Aims: DNA constructs containing HCV antigens have become one of the vaccine candidates for induction of anti-HCV cellular and humoral immunity. In this study, we constructed a novel expressing vector harboring a fusion sequence derived from an overlapping fragment in the middle of NS3 and a truncated core fragment to avoid troubles reported to be associated with full gene express...

Knowing that adenoviral vectors could initiate innate immunity, the ability of E1-deleted recombinant adenovirus (Ad-E1Δ) in induction of B7.1 and IL-2 molecules was studied. Methods: The expression of green fluorescent protein in C1498 cells following transfection of these cells with adenovirus green fluorescent protein vector confirmed the ability of adenovirus vectors in infecting the cells ...

Background: Hepatitis C virus (HCV) infection is one of the most prevalent infectious diseases responsible for high morbidity and mortality worldwide. Therefore, designing new and effective therapeutics is of great importance. The aim of the current study was to construct a DNA vaccine containing structural proteins of HCV and evaluation of its expression in a eukaryot...
