AIM In our study, we investigated the levels of glutamic acid decarboxylase antibody (anti-GAD), islet cell antibody (ICA), thyroperoxidase antibody (anti-TPO), thyroglobulin antibody (anti-TG), antinuclear antibodies (FANA), antibodies to double-stranded DNA (anti-ds DNA), antibody to Sjögren syndrome A antigen (anti-SSA), antibody to Sjögren syndrome B antigen (anti-SSB), Smith antibody (anti...

BACKGROUND Autoimmunity is considered an uncommon but under-recognised cause of cognitive decline. METHODS Serum samples from 3,253 randomly selected subjects enrolled in the Hunter Community Study, aged 55-85 years, were assayed for thyrotropin stimulatory hormone, anti-thyroid peroxidase antibodies (TPO-Ab), anti-nuclear antibodies (ANA) and extractable nuclear antigens (ENA). Cognitive fun...

OBJECTIVE Leptin is an adipokine that regulates body weight and appetite. It is also an inflammatory cytokine that influences immune reactivity and autoimmunity. Leptin levels are increased in obesity and are higher in women than in men. We aimed to determine whether leptin levels, independent of sex and body mass index (BMI), are associated with thyroid autoimmunity. DESIGN This study uses d...

OBJECTIVE Studies in different populations have shown great variation in the prevalence of thyroid diseases in patients with type 1 diabetes mellitus (T1DM). Our aim was to study the prevalence of thyroid disorders such as autoimmunity of thyroid (AIT), thyroid dysfunction, and goiter in children and adolescents with T1DM, compared with age- and sex-matched healthy controls in Isfahan. METHOD...

AIM Many studies demonstrated that alopecia areata (AA) and vitiligo are commonly associated with autoimmune thyroid diseases. We aimed to investigate the frequency of thyroid dysfunctions and autoimmunity related with vitiligo and AA. MATERIAL AND METHODS 200 patients, 92 AA and 108 vitiligo diagnosed, were surveyed retrospectively. The control population was in reference range and from Kony...

In an attempt to explore the natural variable heavy and light chain (VH/VL) pairing of autoantibodies involved in Graves' disease, we constructed a phage-displayed Ab library obtained by in-cell PCR of thyroid-infiltrating cells. We report here the molecular cloning and characterization of human single-chain fragment variable regions (scFv) specific for thyroid peroxidase (TPO) generated from t...

BACKGROUND AND OBJECTIVES B1647 is a cell line derived from bone marrow cells of a patient with acute myeloid leukemia (M2) with a complete erythro-megakaryocytic phenotype and bears both k and p isoforms of c-mpl. Interestingly, spontaneous B1647 cell proliferation is significantly potentiated by thrombopoietin (TPO). DESIGN AND METHODS We aimed to evaluate the proliferative signal transduct...

2014 Aim: The aim of this study was to determine the relationship between thyroid disorders and prolactin in patients with and without lupus activity. Patients & methods: Women with systemic lupus erythematosus (SLE) were evaluated for lupus activity. Serum tri-iodothyronine (T3), serum thyroxine (T4) and thyroid-stimulating hormone (TSH), anti-thyroid peroxidase (anti-TPO) anti-thyroglobulin (...

A heterogeneity in the molecular weight (Mr) of thrombopoietin (TPO) has been reported. We found several thrombin cleavage sites in human, rat, murine, and canine TPOs, and also found that human TPO undergoes selective proteolysis by thrombin. Recombinant human TPO (rhTPO) was incubated with human platelets in the presence of calcium ions to allow the generation of thrombin, and was cleaved int...
