Brucellosis, caused by Brucella spp., is an important zoonotic disease that causes abortion and infertility in cattle and undulant fever in humans. Various studies have examined cell-free native and recombinant proteins as candidate protective antigens in animal models. Among Brucella immunogenes, antigen based on ribosomal preparation has been widely investigated. In this study, the immunogeni...
We have developed a sensitive method for the detection of recombinant antibody-antigen interactions in a microarray format. The biochip sensor platform used in this study is based on an oriented streptavidin monolayer that provides a biological interface with well-defined surface architecture that dramatically reduces nonspecific binding interactions. All the antibody or antigen probes were bio...
Background and Objectives: Rotaviruses are the most important cause of severe diarrhea in infants and young children in both developed and developing countries. Rotaviruses are members of the reoviridae family and contain 11 double- stranded RNA segments. Segment 10 encodes nonstructural glycoprotein NSP4, that can induce diarrhea in newborn mice. It has been suggested that NSP4 may be a key de...
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 ...
Lactobacillus casei ATCC 393 was selected as an antigen delivery vehicle for 6 mucosal immunization against porcine parvovirus (PPV) infection. A 64kDa fragment of PPV 7 major protective antigen VP2 protein was used as the parvovirus antigen model. A 8 recombinant lactobacilli expressing VP2 protein was constructed with plasmid pPG611.1, 9 where expression and localization of the VP2 protein fr...
Recognition of specific pathogen associated molecular patterns (PAMPs) is mediated primarily by members of the Toll-like receptor (TLR) family. Stimulation through these receptors results in quantitative and qualitative changes in antigen presentation and cellular activation, thereby linking innate and adaptive immunity. Consequently, the incorporation of TLR-ligands into vaccines could result ...
Introduction: Among several tuberculosis vaccine candidates for replacement of BCG, ESAT-6 protein has a special role. Since mycobacterium tuberculosis infection most often attacks the lungs, intranasal rout can be regarded as appropriate methods for tuberculosis vaccines and drug delivery. One of the appropriate systems for intranasal vaccine delivery is using biodegradable nanoparticles. Amon...
The identification of a large number of antigens with potential for development of new tuberculosis vaccine has been accomplished in recent years. This study was designed for cloning and expression of ESAT-6 as a potent antigen of Mycobacterium tuberculosis. Selected gene (Rv3875) was amplified by PCR and product was ligated into expressing plasmid vector pQE30 and recombinant pQE30-ES plasmi...
