We report on the antibacterial activities of an 11 residue peptide (FQWQRNMRKVR) homologous to just over half the loop region of human lactoferricin. The peptide, in the form of a multiple antingen peptide (MAP), exerted signi cant antibacterial e ects against a broad spectrum of bacteria including MRSA. Lactoferricin is an iron-binding glycoprotein belonging to the transferrin family and found...

We show here an effective and novel approach to engineer peptide-based vaccines using a chemically defined system, known as multiple peptide antigen systems (MAPs), to protect an inbred mouse strain from infection against rodent malaria. 10 mono- and di-epitope MAP models containing different arrangements and stoichiometry of functional B and/or T helper cell epitopes from the circumsporozoite ...

A novel caspase-3-specific inhibitory peptide and an agonistic peptide that binds to the Fas molecule were discovered using our computer screening strategy called the amino acid complement wave (ACW) method, which is based on the complementarities of interacting amino acids between comprehensive testing peptides and a target protein surface pocket. The precise binding configurations of the desi...

Porphyromonas gingivalis is considered with inducing pulpal inflammation and has lipopolysaccharide (LPS) as an inflammatory stimulator. GV1001 peptide has anticancer and anti-inflammation activity due to inhibiting activation of signaling molecules after penetration into the various types of cells. Therefore, this study examined inhibitory effect of GV1001 on dental pulp cells (hDPCs) stimulat...

objective(s):human cytomegalovirus (hcmv) remains a major morbidity and mortality cause in immuno suppressed patients. therefore, significant effort has been made towards the development of a vaccine. in this study, the expression of the pp65 and gb fusion peptides and fc domain of mouse igg2a as a novel delivery system for selective uptake of antigens by antigen-presenting cells (apcs) in pich...

the rotavirus nonstructural protein 4 (nsp4), is a multi functional protein that play key role in both viral morphogenesis and cytopathic effect associated with cell death. however, the complete biological effect of nsp4 remains to be clarified. since to obtain further knowledge about this protein there is a need for recognizing antibody and there is no commercial antibody against this protein...

interferon is a protein secreted by eucaryotic cells following stimulation by viruses, bacteria, and many other immunogenes. recent medical studies indicate that interferons have effective role in the treatment of virus infections, immunodeficiency and certain types of cancer such as hairy cell leukaemia (hcl). the aim of the present study is to apply yeast strain for secreting human ifnα2b fol...

objective: dna vaccines have been widely used to develop immunity against various pathogens including parasites and viruses. the potential of dna vaccine to induce an effective immune response is related to the expression levels of the encoded protein in eukaryotic cells. therefore, optimization of plasmid dna delivery system is a major concern in protein expression in order to make an efficien...

We have identified in rabbits two hepatic forms of T669 peptide kinases that are very strongly activated after systemic injection with the inflammatory cytokiue interleukin 1 (ID1). The T669 peptide contains a major phosphoryhtion site of the epidermal growth factor receptor, threonine 699 and is a substrate for mitogen-activated protein (MAP) kinases. The kinases were purified to homogeneity a...
