Auto-antibodies (aAbs) to thyroid peroxidase (TPO) interact with a restricted immunodominant region (IDR) divided into two overlapping regions A and B. Among the five major regions structuring the IDR/B, regions 210-225, 353-363, 549-563, 713-720 and 766-775, region 353-363 constitutes an important anchor point for the binding of TPO-specific aAbs in sera from Hashimoto's and Graves' patients. ...

BACKGROUND During the postpartum period, women are at risk for the new onset of both auto-immune thyroid disorders and depression. The presence of thyroid peroxidase antibodies (TPO-ab) during early gestation is predictive for postpartum auto-immune thyroid dysfunction. The aim of this study was to investigate the association between TPO-ab status during early gestation and first-onset postpart...

Cardiac toxicity has been the major concern when using doxorubicin (DOX) in cancer therapy. Thrombopoietin (TPO) protects cardiac cells from DOX-induced cell damage; however, its molecular mechanism remains exclusive. The anti-autophagic and anti-apoptotic effects of TPO upon DOX treatment were studied in the cardiac H9C2 cell line, with bafilomycin A1 treatment as a positive control for autoph...

We previously reported the aberrant growth of granulocyte-macrophage (GM) progenitors induced by a combination of stem cell factor (SCF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in juvenile chronic myelogenous leukemia (JCML). We examined here the effects of thrombopoietin (TPO) on the proliferation and differentiation of hematopoietic progenitors in JCML. In serum-deprived...

BACKGROUND Hashimoto's thyroiditis (HT) results from a parenchymal infiltration by Th1 T cell clones that ultimately may cause tissue destruction. We analysed here whether the quantitative assessment of the cytokine profile in peripheral lymphocytes could help for the evaluation of patients with HT. METHODS We added to a flow cytometric evaluation of lymphocyte subpopulations, an assay to ide...

The knowledge about dietary habits and their influence in the development of autoimmune thyroid disease is insufficient. The aim of this study was to analyse the association of dietary factors and plasma thyroid peroxidase antibodies (TPO-Ab) and/or thyroglobulin antibodies (Tg-Ab). The study enrolled 1887 participants originating from the South Croatia. Participants with elevated plasma TPO-Ab...

OBJECTIVE To determine which of 3 different plate angles (20°, 25°, 30°) used in double pelvic osteotomy (DPO) would result in the most similar acetabular angle (AA) achieved with a 20° triple pelvic osteotomy (TPO) technique in dogs. STUDY DESIGN Experimental anatomic study. ANIMALS Cadaveric canine pelves (n = 8). METHODS Transverse plane computed tomographic images of cadaveric pelves ...

OBJECTIVES To evaluate the expression and significance of CK19, TPO, and HBME-1 in the differential diagnosis of papillary thyroid carcinoma (PTC) and nonmalignant nodules. METHODS Tissue samples were obtained from 257 patients with PTC and 149 patients with nonmalignant thyroid specimens, and immunohistochemical staining for CK-19, TPO, and HBME-1 was performed. RESULTS The expression of C...

Background. Postpartum thyroiditis (PPT) is a common triphasic autoimmune disease in women with thyroid peroxidase (TPO) autoantibodies. This study evaluated women's thyroid disease symptoms, physical findings, stress levels, and thyroid stimulating hormone (TSH) levels across six postpartum months in three groups, TPO negative, TPO positive, and PPT positive women. Methods. Women were recruite...

The regulation of megakaryocytopoiesis and thrombopoiesis appears to be under the control of an array of hematopoietic growth factors. To determine the relationship of endogenous thrombopoietic cytokine levels and circulating platelet (PLT) counts, we measured the levels of thrombo-poietin (TPO), interleukin-11 (IL-11), and interleukin-6 (IL-6) in patients with significant thrombocytopenia seco...
