Virus evolves rapidly to escape vaccine-induced immunity, posing a desperate demand for efficient vaccine development biotechnologies. Here we present an express vaccine development strategy based on CRISPR/Cas9 and Cre/Lox system against re-emerging Pseudorabies virus, which caused the recent devastating swine pseudorabies outbreak in China. By CRISPR/Cas9 system, the virulent genes of the new...

the development of a therapeutic vaccine against human papillomavirus (hpv) is important for the control of cervical cancer. e7 is the major transforming protein produced in cervical cancers, and therefore represents potential tumor-specific antigen that could be the target of immunotherapy for cervical cancer. among different vaccine strategies, protein-based vaccines are capable of generating...

The aim of this paper is to analyse the current status and scientific value of malaria vaccine approaches and to provide a realistic prognosis for future developments. We systematically review previous approaches to malaria vaccination, address how vaccine efforts have developed, how this issue may be fixed, and how external forces shape vaccine development. Our analysis provides significant in...

The panel addressed four main areas of vaccine development and use: diseases of public health importance for which no vaccine is available; diseases for which an existing licensed vaccine is not optimal and alternative vaccines are under development; diseases for which a vaccine exists but is not being used optimally; and diseases requiring vaccines of specialized or limited use, such as those ...

Background: There is a growing interest in development of an effective adjuvant system for improving DNA vaccines. Recent findings have confirmed an important role for autophagy in both innate and adaptive immunity. The current study was undertaken to determine the efficacy of autophagy induction with Beclin-1, as a novel adjuvant system, in mice immunized with human papilloma virus (HPV) DNA v...

  The identification of a large number of antigens with potential for development of new tuberculosis vaccine has been accomplished in recent years. This study was designed for cloning and expression of ESAT-6 as a potent antigen of Mycobacterium tuberculosis. Selected gene (Rv3875) was amplified by PCR and product was ligated into expressing plasmid vector pQE30 and recombinant pQE30-ES plasmi...

The hepatitis C virus (HCV) is an infection that affects the liver tissues in humans, leading to the development of effective prophylactic and therapeutic HCV vaccines to prevent a global epidemic. Scientists consider it challenging to produce a therapeutic vaccine for the treatment of hepatocellular carcinoma as opposed to a preventative vaccine. However, several drawbacks are involved with a ...

Background: Tuberculosis is a life threatening disease that is partially prevented by BCG vaccine. Development of more effective vaccines is an urgent priority in TB control. Ag85a and Tb10.4 are the members of culture filter protein (CFP) of M. tuberculosis that have high immunogenicity. Objective: To analyze the immunogenicity of Ag85a-Tb10.4 DNA vaccine by enzyme-linked immunosorbent as...
