We have designed and constructed a novel chimeric protein that consisted of a single domain of protein A and luciferase derived from sea-firefly Vargula hilgendorfii with the goal of obtaining a heterofunctional immunological tool. The structural gene of luciferase was fused to the 3' terminus of the D domain gene of protein A with/without a short linker of five amino acids. The resulting const...
The major outer membrane protein (MOMP) of Chlamydia trachomatis is a highly antigenic and hydrophobic transmembrane protein. Our attempts to express the full-length protein in a soluble form in Escherichia coli and in transgenic plants failed. A chimeric gene construct of C. trachomatis serovar E MOMP was designed in order to increase solubility of the MOMP protein but with retained antigenici...
A chimeric poliovirus type 1 (PV1) genome was constructed in which the 3D RNA polymerase (3D(pol)) coding sequences were replaced with those from coxsackievirus B3 (CVB3). No infectious virus was produced from HeLa cells transfected with the chimeric RNA. Processing of the PV1 capsid protein precursor was incomplete, presumably due to inefficient recognition of the P1 protein substrate by the c...
background: bacterial superantigen staphylococcal enterotoxins (ses), has stimulated polyclonal t cells irrespective of their antigen specificity, resulted a massive release of cytokines, and suggested that they could be assigned as a candidate of new antitumor agents. recent attempts have done to specifically target superantigens towards tumors, subsequently monoclonal antibodies and tumor-rel...
Infectious bronchitis virus (IBV) poses a severe threat to the poultry industry and causes heavy economic losses worldwide. Vaccination is the most effective method of preventing infection and controlling the spread of IBV, but currently available inactivated and attenuated virus vaccines have some disadvantages. We developed a chimeric virus-like particle (VLP)-based candidate vaccine for IBV ...
In an attempt to introduce a large peptide that is not normally translocated across membranes into the cytosol of eukaryotic cells, we created a new chimeric protein termed CEDH between Pseudomonas aeruginosa exotoxin A (ETA) and a variant enzyme of Mus musculus dihydrofolate reductase (DHFR) with reduced affinity for antifolates, ETA(1-413).DHFR(1-187).ETA(609-613). We have defined, geneticall...
Microviruses (canonical members are bacteriophages phiX174, G4, and alpha3) are T=1 icosahedral virions with an assembly pathway mediated by two scaffolding proteins. The external scaffolding protein D plays a major role during morphogenesis, particularly in icosahedral shell formation. The results of previous studies, conducted with a cloned chimeric external scaffolding gene, suggest that the...
The development of modular constructs that include antigenic regions targeted by protective immune responses is an attractive approach for subunit vaccine development. However, a main concern of using these vaccine platforms is how to preserve the antigenic identity of conformational B cell epitopes. In the present study we evaluated naturally acquired antibody responses to a chimeric protein e...
A technology has been developed for efficient isolation of a stable pool HIF1a overexpressing mouse fibroblasts using high-throughput selection cell clones on cellulose carrier. The pHIF1a-CBD-PDGFR genetic construct generated containing EYFP reporter, target sequence gene (a key factor adaptation to hypoxia in wound healing and regeneration) CBD/PDGFR chimeric construct. presence CBD (cellulos...
