objective: toxoplasma gondii is an obligate intracellular protozoan that causes toxoplasmosis in human and animal. in recent years, significant progress has been made in the identification of vaccine candidates which can induce protective responses. in this study we used complete rhoptry protein 2 gene of toxoplasma gondii as a single dna vaccine and evaluated its immune responses in comparison...

background: mycobacterium tuberculosis is the causative agent of tuberculosis (tb). bacille calmette-guerin (bcg) vaccine, is not effective in adults, therefore, many efforts have been made to produce an effective adult tb vaccine. the aim of this study was to develop a new tuberculosis dna vaccine candidate encoding a recombinant hspx-ppe44-esxv fusion antigen of m. tuberculosis. methods: a fu...

We introduce the interval order polytope of a digraph D as the convex hull of interval order inducing arc subsets of D. Two general schemes for producing valid inequalities are presented. These schemes have been used implicitly for several polytopes and they are applied here to the interval order polytope. It is shown that almost all known classes of valid inequalities of the linear ordering po...

Correlation of hepatitis C virus (HCV) spontaneous resolution with Th1 and CD8(+)CTL responses during natural infection implies the potentiality of poly-CTL-epitopic HCV vaccines. We recently reported in silico design and construction of DNA vaccines (pcPOL-plasmids) harboring HCV CTL epitopes. Herein, we provide data of mice immunization by pcPOL, (encoding; core(132-142) [C], E2(405-414) [E(4...

Background & Objective: DNA vaccines as a new generation of vaccines require adjuvant to improve vaccine immunogenicity; adjuvants can also increase the DNA vaccine efficacy. In this study, the effects of the host’s interferon-inducible Mx protein as bio adjuvant and conventional alum adjuvant were evaluated.   Materials & Methods: The BALB/c mice were immunized by different prime-boost strate...

Background: Cell mediated immunity, especially cytotoxic T cell responses against HIV-1 infection, plays a critical role in controlling viral replication and disease progres-sion. DNA vaccine is a novel technology which is known to stimulate strong cellular immune responses. Many DNA vaccines have been tested for HIV infection but there is still no effective vaccine against this infection. Cons...

Background:  With one-third of the world’s population infected, tuberculosis (TB) is one of the most common infectious diseases and a major public health problem, especially in developing countries. The efficacy of the BCG vaccine for controlling the disease in adults is poor. The development of an effective TB vaccine is a global objective. An effective tuberculosis vaccine should s...

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...
