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...

This study aimed to investigate β-amyloid peptide (Aβ) plaques and changes of astroglia microglia in mice with Alzheimer’s disease (AD). In this study, 18 transgenic amyloid precursor protein (APP)/presenilin-1 (PS1) were randomized into the Aβ3-10-KLH vaccine, Aβ1-42 phosphate-buffered saline (PBS) groups. The injected at different time points. Morris water maze test was used identify spatial ...

Abstract Background The topical inflammatory soup can model the inflammation of dura mater causing hypersensitivity and activation trigeminal system, a phenomenon present in migraineurs. Calcitonin gene-related peptide, transient receptor potential vanilloid-1 receptor, neuronal nitric oxide synthase are important sensitization process there. 5-HT 1B/1D agonists, triptans used as treatment migr...

Atrial natriuretic peptide (ANP) gene expression was localized in the rat gastric antrum using immunohistochemistry and in situ hybridization to mucosal cells in the lower portion of the antropyloric glands. Colocalization of immunoreactive ANP, long-acting natriuretic peptide, i.e., proANP-(1-30), and serotonin in these cells identified them to be enterochromaffin cells. Fasting for 72 h in 8-...

objective(s) definite diagnosis of hirschsprung’s disease (hd) is based on histopathological study, but there are limitations associated with standard histology and histochemistry in this regard. the aim of this study was to investigate calretinin immunostaining patterns in both ganglionic and aganglionic hd intestinal specimens and to compare them with control specimens. materials and methods ...

inverted follicular keratosis (ifk) a benign tumor of skin appendages which is mostly presented as a solitary nodule with keratotic or scaling surface on the face of a middle aged or old patients but it can develop in other parts of the body. different studies have lead to development of different theories about the role of human papillomavirus (hpv) in this kind of skin tumor. the purpose of t...

background and objective: histological grading has prognostic and therapeutic implications in meningioma. however, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. p63 gene is a novel p53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. in this study,...
