Background: Anti-thyroid peroxidase antibody (anti-TPO antibody) is a member of thyroid autoantibodies which are important in inducing and also diagnosing autoimmune thyroid diseases. Thyroid autoimmunity can cause several forms of thyroiditis and abnormal thyroid functions, ranging from hypothyroidism to hyperthyroidism. Objective: To evaluate the relationship between serum levels of anti-TPO ...

Foot and mouth disease (FMD) is a contagious animal disease that causes irreparable damage to the economy of countries, including Iran in which this disease is a native one. Among the ways to combat FMD are vaccination and slaughter. Due to the specific situation of Iran, it is not possible to kill infected animals. Therefore, vaccination is the most important way to fight this disease. S...

We used a monoclonal anti-idiotypic antibody that is directed against a Sendai virus-specific helper T-cell clone to induce an anti-viral immune response in vivo. Splenocytes primed with the anti-idiotypic antibody mediated an antigen-specific cytolytic response. Preimmunization of mice with the anti-idiotypic antibody resulted in protection against a subsequent lethal infection with Sendai virus.

background: the specific antibody response against newcastle disease virus (ndv) in the blood serum of chickens hatched from eggs exposed to low dose gamma-radiation was studied. materials and methods: two groups of eggs of commercial meat chicken lines were irradiated with the dose of 0.30 gy 60co gamma-rays before incubation and on the 19th day of incubation, respectively. the same number of ...

Aqueous glutaraldehyde has been polymerized under alkaline conditions in the presence of a surfactant to yield microspheres of varied diameters. Microbeads of a nominal 300 nm diameter, made fluorescent via fluoresceinisothiocyanate, were used as a carrier of rabbit anti-human red blood cell antibodies. Specific labeling of the human red blood cells as well as diagnostic use of these fluor...

Objective(s): Enterotoxigenic Escherichia coli (ETEC) is known as the most common bacterial causes of diarrheal diseases related to morbidity and mortality. Heat-labile enterotoxin (LT) is a part of major virulence factors in ETEC pathogenesis. Antigen entrapment into nanoparticles (NPs) can protect them and enhance their immunogenicity.Materials and Methods: In the present study, recombinant L...

Liver cytosol antibody type 1 (anti-LC1) is reported to be a marker of 2 autoimmune hepatitis (AIH), liver disease (AILD). However, anti-LC1 not entirely disease-specific, and its clinical value in other hepatic diseases has been well elucidated. Our study aimed explore the associations between diagnoses outcome decompensated cirrhosis or failure (DC/LF) patients positive for anti-LC1. A total ...

objective(s): in this study, for the first time, mf59 adjuvant was used to develop a cholesteryl ester transfer protein (cetp) vaccine. the efficacy of the vaccine was compared with the efficacy of cetp vaccine formulated with alum/cpg, the formulation that its immunogenicity has been already demonstrated in rabbit and mice. materials and methods: tetanus toxoid- cetp peptide (tt-cetp) was mixe...

background: our information regarding immunity to toxoplasmosis among reproductive age women is indeterminate and there is significant variation between reported results; it is necessary to perform a meta-analysis study on subjects to obtain required findings and develop preventive measures accordingly. objective: estimation level of immunity to toxoplasmosis in reproductive ages. materials and...

background: helicobacter pylori infection is one of the most common gastrointestinal infections worldwide. predominant t-helper 1 (th1) responses with increased gamma interferon (ifn- γ) levels have been proposed to play an important role in h. pylori-induced peptic ulcer. however, bacterial factors contributing to the initiation of th1 polarization of h. pylori-specific immune responses have n...
