Introduction: Long term complications of hepatitis C virus (HCV) infection include fibrosis, cirrhosis, and hepatocellular carcinoma and although the disease is treatable with the newly introduced direct acting antivirals, but factors such as drug resistance, viral genotype and adverse effects can limit the effectiveness of therapy. Therefore, development of effective, safe and affordable proph...

introduction: omp31 is animmunodominant and protective antigen conserved in brucella species and a good candidate for vaccine design. material & methods: the present study aimed at in silico design of the truncated omp31 (tomp31) using bioinformatic tools and to express the selected form in escherichia coli (e. coli) results and conclusion: various bioinformatically calculated scores for the mo...

The aim of this study is to identify, clone and express a Mycobacterium avium subsp. paratuberculosis specific immunogenic antigen candidate, in order to develop better reagents for diagnosis and vaccines for the protection of the host. Therefore, MAP2191 gene (a member of MAPmce5 operon) from MAP, was isolated and characterized by Bioinformatics tools and <e...

conclusions the results of the present study showed that the baculovirus expression system (sf9 cells) was able to express truncated orf2 and truncated orf2-nsp4 proteins as a potential candidate vaccine. background the hepatitis e virus (hev) accounts for hepatitis e infection with relatively high mortality rate in pregnant women that can lead to fulminant hepatitis. the baculovirus expression...

expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...

Background: Septins are members of highly conserved polymerizing GTP binding proteins well described in the animal kingdom. 14 Septin proteins have been characterized in humans (SEPT1-SEPT14), some of which are tissue-specific. All of 14 genome-mapped human septins contain a highly conserved central GTP-binding domain which is very critical in GTPase signaling properties as well as oligomerizat...

Background: Although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. Objective: The aim of this study was to clone the first 1100 bp of the C. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...
