Background and Aims: Virus-like particles (VLPs) have been suggested to be a promising recombinant vaccine approach. Several studies have reported that the influenza VLPs produced in insect cells is an effective vaccine candidate. Due to crucial role of matrix M1 protein in assembly and budding of Influenza particles, in all VLPs structures, M1 protein have been considered as a main component. ...
background type 1 diabetes mellitus is one of the metabolic diseases that cause insulin-producing pancreatic ß cells be destroyed by immune system self-reactive t cells. recently, new treatment methods have been developed including use of the stem cells, ß islet cells transplantation and gene therapy by viral and non-viral gene constructs. objectives the aim of this project was preparing the n...
Isolating and cloning of plant protease inhibitor (PIs) genes and transforming them to the genome of other plants have paved the way for producing resistant transgenic plants against pests. Knowing that cystatins act as inhibitor factor against cysteine protease, short and long cystatin genes were isolated from maize mRNA. By using specific primers, cDNA of these genes were constructed and cl...
Immunogenicity induced by recombinant plasmids based on the BAB1_0267 and BAB1_0270 open reading frames (ORFs) of Brucella abortus 2308 was evaluated. Bioinformatics analyses indicate that the BAB1_0267 and BAB1_0270 ORFs encode a protein with a SH3 domain and a Zn-dependent metalloproteinase, respectively. Both ORFs have important effects on intracellular survival and replication of B. abortus...
The aim of this study was to construct a plasmid expressing glycoprotein IIb-IIIa (GPIIb/IIIa) and D-dimer single-chain bispecific antibody for the targeted therapy of thrombosis. The phosphorylated gene encoding the anti-GPIIb/IIIa single-chain variable fragment (scFv) and the gene encoding the anti-D-dimer scFv were amplified by PCR and linked in tandem by blunt-end ligation. The recombinant ...
Heterologous "prime-boost" regimens that involve priming with plasmid DNA vaccines and boosting with recombinant viral vectors have been shown to elicit potent virus-specific cytotoxic T-lymphocyte responses. Increasing evidence, however, suggests that the utility of recombinant viral vectors in human populations will be significantly limited by preexisting antivector immunity. Here we demonstr...
The recombinant Pseudomonas putida strain CB1-9, which acquired the ability to grow on chlorobenzenes, contains a 33-kilobase (kb) plasmid (pKFL3) which lacked homology to an indigenous 15-kb plasmid (pKFL1) in Pseudomonas alcaligenes C-0 parent but was homologous to a 55-kb plasmid (pKFL2) from the P. putida R5-3 parent. Chromosomal DNA of P. alcaligenes C-0 hybridized to probes prepared from ...
As an attempt to increase the resistance to Newcastle Disease Virus (NDV) and so further reduction of its risk on the poultry industry. This work aimed to build the eukaryotic gene co-expression plasmid of neuraminidase (NA) gene and myxo-virus resistance (Mx) and detect the gene expression in transfected mouse fibroblasts (NIH-3T3) cells, it is most important to investigate the influence of th...
Messenger RNAs for mouse embryonic globins were purified from yolk sac derived eyrthroid cells in mouse fetuses. Double stranded DNAs complementary to these messengers were synthesized and blunt end ligated to a EcoRI digested and DNA polymerase I repaired pBR322 plasmid. Of the ampicillin resistant transformants, one contained a plasmid with globin-specific cDNA. The inserted sequence is about...
SAL-TOL in vivo recombinant plasmid pKF439 was characterized in a strain from a mixed culture of bacteria harboring various degradative plasmids. Analysis of the gene organization of pKF439 revealed that the 57-kilobase TOL fragment, including the 40-kilobase TOL metabolic region, was inserted into the complete SAL replicon at the position of SmaI-C within XhoI-B of SAL. The molecular size of p...
