Lipopolysaccharide (LPS) is a major component of Gram-negative bacteria cell walls and is a well-known potent inducer of inflammation and pathogens of inflammatory bone loss. Formation of osteoclasts is highly dependent on the presence of macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor kappa-B ligand (RANKL). Recent reports indicate that biological preparat...
Background: Apart from genetic and environmental factors, activation of autoreactive mechanisms has been proposed to play a role in the pathogenesis of schizophrenia. In re-cent years, considerable work has been carried out to understand the role and contribution of the immune system in this disease. Objective: To investigate the T cell response to phytohaemagglutinin (PHA) and determine the se...
Background: Selective antibody deficiency with normal immunoglobulins (SADNI) may be identified as part of distinct primary or secondary immunodeficiency disorders. The clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. Objectives: To evaluate SADNI in patients with recurrent sinopulmonary infections and its relation to IgG subclas...
INTRODUCTION Epstein-Barr virus exposure appears to be an environmental trigger for rheumatoid arthritis that interacts with other risk factors. Relationships among anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status have been observed in patients with rheumatoid arthritis from different populations. OBJECTIVE To perform an association analysis of anti-Epstein...
Background: Human CD34 is a transmembrane glycoprotein which is expressed in human hematopoietic stem cells (HSCs) and the small- vessel endothelial cells of a variety of tissues. CD34 plays a critical role as a marker for diagnosis and classification of leukemia. Anti CD34 antibodies are used for isolation and purification of HSCs from bone marrow, peripheral blood and cord blood. Objective: ...
introduction to define the clinical features, biochemical and histological findings and outcome of three forms of autoimmune hepatitis. materials and methods in a cross sectional study between november 2001 to january 2008 in tehran and mashhad university of medical sciences, 61 children who diagnosed as aih (40 girls and 21 boys) have been analyzed for their clinical, serological, and histol...
Introduction: Vaccination with the major surface antigen of hepatitis B virus (HBsAg) induces anti-HBs antibody production and level of 10 IU/L is considered protective. It has been shown that the level of anti-HBs antibody does wane after vaccination. The aim of this study was to evaluate the persistence of anti-HBs antibodies in healthy Iranian children 10 years after primary vaccination. Me...
Background: Erythropoietin (EPO) was first known as a factor for red blood cell proliferation and differentiation. New studies show the effects of EPO on immune system. Objective: In this study, the effects of pretreatment with recombinant human erythropoietin (rHuEPO) on the anti-human leukocyte antibody (anti-HLA) titer were determined. Methods: Three groups of rats were sensitized with human...
The exchange of histones for transition proteins (TNPs) and finally protamines is an essential process during spermatogenesis that enables the strong condensation of chromatin during sperm formation. Research on this process obviously depends on the availability of specific antibodies recognizing these nuclear proteins. A commercial antibody generated against human protamine-2 (PRM2) has been d...
