The Evaluation of Hepatitis C Virus Core Antigen in Immunized Balb/C Mice
BACKGROUND Hepatitis infection represents one of the important causes of morbidity and mortality in developing countries, however there is not any effective vaccine against hepatitis C which is one of the significant problems in vaccine project. OBJECTIVES The aim of the present study is to evaluate the role of HCV core protein in inducing IFN-Gamma secretion and TCL activities as a vaccine i...
متن کاملExpression of Hepatitis B Virus Core Antigen in Native and Fusion Forms in E. coli
DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
متن کاملEnhanced Immune Responses of a Hepatitis C Virus core DNA Vaccine by co-Inoculating Interleukin-12 Expressing Vector in Mice
Background: Hepatitis C (HCV) is a worldwide problem without an effective vaccine with more than 170 million chronically infected people worldwide. DNA vaccines expressing antigenic portions of the virus with adjutants have recently been developed as a novel vaccination technology. Objectives: In the present study, a DNA vaccine expressing HCV core protein was developed with IL12 as a genetic a...
متن کاملClinical utility of hepatitis C virus core antigen quantification in patients with chronic hepatitis C.
BACKGROUND Hepatitis C virus (HCV) core antigen has been proposed as a surrogate marker of HCV replication. HCV core antigen detection and quantification can thus theoretically be used instead of nucleic acid testing (NAT) to diagnose infection and manage antiviral therapy, with several advantages compared to HCV RNA assays. HCV core antigen can now be easily detected and quantified by means of...
متن کاملImmunogenicity Evaluation of a DNA Vaccine Expressing the Hepatitis C Virus Non-Structural Protein 2 Gene in C57BL/6 Mice
Backgrounds: Most of the hepatitis C virus (HCV) infections elicit poor immune responses and 75% to 85% of cases become chronic therefore, the development of an effective vaccine against HCV is of paramount importance. In this study, we aimed to evaluate co-administration of HCV non-Structural Protein 2 and IL-12 DNA vaccines in C57BL/6 mice. Methods: A plasmid encoding full-length HCV NS2 prot...
متن کاملThe Absence of Hepatitis C Virus Infection Among Patients with Hepatitis B virus in Mashhad, Iran
Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...
