Case presentation We report the case of a girl with celiac disease who subsequently developed IgE mediated hypersensitivity to wheat. The patient is a Caucasian female who was diagnosed with celiac disease at 18 months of age after presenting with recurrent vomiting and failure to thrive. Her anti-tTG antibody level was greater than 200 E.U. and biopsy results from endoscopy were consistent wit...

One of several postulated roles for tissue transglutaminase (tTG) is the stabilization and assembly of extracellular matrix via peptide cross-linking. We previously determined that tTG activity increased in an animal model of hepatic fibrogenesis and in human liver disease. To further study the role of tTG in liver disease, we initiated investigations into the effect of a proinflammatory mediat...

type i diabetes mellitus (dm) is frequently associated with autoimmune thyroid disease (atd). association of atd and type i dm has been described with varying frequencies but there is still debate about the situation in the iranian population. we investigated the prevalence of anti thyroid peroxidase (anti-tpo) antibodies and atd in children and adolescents with type i dm. a total of 145 patien...

introduction: leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. as a consequence, the use of filter technology for leukoreduction has been widely practiced .according to aabb accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...

about 8% of the general population suffers from autoimmune diseases, from which 78% are women. one of the most important causes of thyroid diseases is autoimmunity in origin, and it seems that people with thyroid diseases present more signs of asthma. this study was therefore designed to investigate the frequency of autoimmune thyroid diseases in women suffering from bronchial asthma. in a cros...

background: in lupus nephritis (ln), deposition of pathogenic autoantibodies in the glomeruli is mediated via cross-reactivity with alpha-actinin. association of serum alpha-actinin antibody (aαa) with ln has been shown in a few studies but the results are controversial. methods: eighty patients into entered the study. the diagnosis of sle was confirmed according to the american college of rheu...

background: immunopathological and inflammatory processes play important roles in the initiation and development of ischemic heart disease (ihd). objective: the aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (rf), anti-nuclear antibodies (ana), anti-small nuclear ribonucleoprotein (anti-sm), anti-phosphatidylserine (anti-ps) and anti-car...

background: auto antibodies to zona-pellucida (aza) seem to be important autoantibodies implicated in reproduction, with substantial role in both endocrine and reproductive functions of the human ovary. there are some debates on the relation of aza with infertility, repeated in vitro fertilization (ivf) attempts, and outcome of it. objective: in this study, we assessed the presence of aza in th...

Background: Invariant natural killer cells (iNKT) are an important immunoregulatory T cell subset. Currently several flow cytometry-based approaches exist for the identifi-cation of iNKT cells, which rely on using the 6B11 monoclonal antibody or a combina-tion of anti-Vα24 and anti-Vβ11 antibodies. Objective: The aim of this study was to compare the ability of two flow cytometry-based methods f...

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: t...
