hepcidin is an innate immune element which decreases the iron absorption from diet and iron releasing from macrophage cell. in contrast to the chemical iron chelators, there has been limited effort applied to the specific use of hepcidin as a new drug for decreasing the iron overload. hepcidin is produced in different biological systems. for instance, e-coli is used for human hepcidin expressio...

The world species of Zambion Kasparyan (Hymenoptera: Ichneumonidae: Tryphoninae) are revised including re-descriptions of Zambion monodon Kasparyan and Zambion hirtum Delobel. Five new species are described: Zambion kasparyanisp. n., Zambion rogerisp. n., Zambion eileenaesp. n., Zambion wahlisp. n. andZambion broadisp. n. A key to species is provided. The genus is endemic to Africa (Angola to K...

A recombinant baculovirus harboring the hemagglutinin (HA) gene of African swine fever virus, with homology to the T-lymphocyte surface antigen CD2, was constructed. The efficient expression of the HA gene was determined by immunofluorescence and Western blot studies on insect cells infected with the recombinant baculovirus. The baculovirus-expressed HA showed hemadsorption and erythrocyte-aggl...

BACKGROUND Baculovirus, which has a width of 40 nm and a length of 250-300 nm, can display functional peptides, receptors and antigens on its surface by their fusion with a baculovirus envelop protein, GP64. In addition, some transmembrane proteins can be displayed without GP64 fusion, using the native transmembrane domains of the baculovirus. We used this functionality to display human proreni...

The capsid protein gene of tobacco ringspot virus (TobRV), which had been modified to contain an amino-terminal methionine codon, was ligated into a baculovirus transfer vector downstream from the polyhedrin promoter. The resulting plasmid was cotransfected with linearized baculovirus DNA into insect cells. Recombinant baculovirus expressed high levels of the TobRV capsid protein that assembled...

Gene delivery to neural cells is central to the development of transplantation therapies for neurological diseases. In this study, we used a baculovirus derived from the domesticated silk moth, Bombyx mori, as vector for transducing a human cell line (HEK293) and primary cultures of rat Schwann cells. Under optimal conditions of infection with a recombinant baculovirus containing the reporter g...

Virus transmission and the prevalence of infection depend on multiple factors, including the interaction with other viral pathogens infecting the same host. In this study, active replication of an iflavirus, Spodoptera exigua iflavirus 1 (order Picornavirales) was observed in the offspring of insects that survived following inoculation with a pathogenic baculovirus, Spodoptera exigua multiple n...

Efficient gene delivery of a baculovirus-derived vector (BV-p53-lacZ) to a human osteogenic sarcoma cell line, Saos-2, was serendipitously found while evaluating the vector for gene delivery to human p53-null tumour cells in a previous study. Therefore, we investigated other human, rat and mouse osteogenic sarcoma and other types of tumour cell lines for transduction efficiency via baculovirus ...
