objective: helicobacter pylori is a spiral, microaerophilic gram negative bacterium, that multiplies and causes infection in human gastric mucosal layer. h.pylori infection, followed by destruction of gastric epithelial tissue, leads to gastric chronic inflammation, which can cause gastric and peptic ulcers. new approaches have focused on using specific treatments, such as immunotherapy, to era...

with advent and development of dna recombinant technology and advantages of p. pastoris expression system, fusion (f) protein of pprv expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against ppr disease. in this study, f gene of pprv nigeria 75/1 strain (1637 bp) was amplified using rt-pcr and purified. it was then clon...

conclusions based on this similarity and our bioinformatics evaluations, this mentioned alpha-amylase gene can be expressed in s. cerevisiae as extracellular enzyme. results the presence of alpha-amylase gene in recombinant bacteria was certificated by colony-pcr method. after extraction of recombinant vector from e. coli, the competent s. cerevisiae cells were transformed using polyethylene gl...

background and aims: since the produced recombinant proteins by molecular genetics techniques commonly have some limitations in the application, chimeric protein are introduced. chimeric proteins have found widespread application for the study of protein folding, structure stability, function and immunogenisity. methods: according to the known immunomodulatory effect and structure of hsp70 mole...

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...

During apoptosis, DNA undergoes fragmentation and caspase-3 cleaves poly(ADP-ribose) polymerase (PARP) into both a 24-kDa fragment containing the DNA binding domain and an 89-kDa fragment containing the catalytic and automodification domains. Atomic force microscopy revealed that recombinant full-length PARP bound to plasmid DNA fragments and linked them into chainlike structures. Automodificat...

A recombinant plasmid for expression of full-length human DNA ligase I (phLig-I) was constructed in a plasmid/phage chimeric vector, pTD-T7N, which was derived from pUC118 by oligonucleotide-directed mutagenesis. The insert contained a 2757-base pair coding sequence for a whole human DNA ligase I and an extra ACC codon adjacent to the ATG initiation codon. This ACC codon was required for achiev...

OX40 is a costimulatory molecule that belongs to the tumor necrosis factor receptor (TNFR) superfamily. agonist-based combinations are emerging as promising candidates for novel cancer immunotherapy. Clinical trials have shown agonist antibodies could lead better results in patients. Using hybridoma platform and three different types of immunization strategies, namely recombinant protein, DNA, ...

Background: During the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. Lactococcus lactis (L. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. Hence, L. lactis is an ideal candidate for mucosal immunotherapy. Profilin (Che a 2), the major allergen in Chenopodium album, is one ...
