Injection of rabbits with arsanil-sulfanil-thyroglobulin without adjuvant resulted in the production of hemagglutinating and precipitating antibody to native thyroglobulin and thyroiditis. Following a latent period of 1 month, these same rabbits responded to an injection of native thyroglobulin with an increase in both circulating antibody to native thyroglobulin and severity and frequency of t...

Thyroglobulin binds to isolated thyroid plasma membrane preparations. Binding is pHand temperaturedependent with lo-fold better binding at pH 5.0 and 37°C than at 0°C and pH 6.0 through pH 7.5. Binding is, however, maximal in 90 min at all pH values and temperatures examined. Although salts can inhibit or enhance thyroglobulin binding depending on the temperature or pH, conditions approaching t...

Purified rat tumor thyroglobulin from the experimental rat thyroid tumor, line 1-1C2, was studied for its thyroid hormone content after in vivo and in vitro iodination and compared with normal and desialylated normal rat thyroglobulin. Tumor thyroglobulin had a very low sialic acid and iodine content; after in vivo iodination it contained only small amounts of triiodothyronine (T3) and no detec...

BACKGROUND Celiac disease (CD) is a common genetically transmitted immune mediated disease. METHOD Seventy three type 1 DM patients attending the Diabetes, Metabolic and Endocrinology outpatient clinic were recruited in the study. Thorough history taking and medical examination were done. They were screened for the prevalence of celiac disease by ELISA for coeliac disease antibodies against t...

INTRODUCTION Clinical manifestations of Immunoglobulin A Deficiency (IgAD) include recurrent infections, atopy and autoimmune diseases. However, to our knowledge, the concomitant evaluations of autoimmune diseases and autoantibodies in a cohort of IgAD patients with current age > 10 years-old and their relatives have not been assessed. OBJECTIVES To evaluate autoimmune diseases and the presen...

Pooled normal polyspecific IgG for therapeutic use (IVIg) contain anti-idiotypes against idiotypic determinants expressed by autoantibodies from patients with a variety of autoimmune diseases. In the present study, antiidiotypes in IVIg are shown to recognize a cross-reactive idiotype on human anti-thyroglobulin (TG) autoantibodies, that was defined by heterologous antiidiotypic antibodies, ter...

Thyroglobulin gene mutation is a rare cause of congenital hypothyroidism, but thyroglobulin gene mutations are thought to be associated with thyroid cancer development. A 21-year-old Japanese man treated with levothyroxine for congenital hypothyroidism had an enlarged thyroid gland with undetectable serum thyroglobulin despite elevated serum TSH level. The patient was diagnosed with thyroglobul...

This paper describes the incidence of positive serological tests for autoantibodies to gastric mucosal antigen and to thyroglobulin in patients with chronic gastritis, pernicious anaemia, and postgastrectomy gastritis. The results support the recent concept (British Medical Journal, 1962) that diffuse atrophic gastritis, which is the essential lesion in most cases of pernicious anaemia, may hav...

The case of a 14-year-old mongrel dog with a thyroid tumor treated by thyreoidectomy is described. The resected tumor was subjected to a detailed morphological and immunohistochemical analysis utilizing antibodies directed against thyroglobulin, calcitonin, chromogranin A, cytokeratin 19, thyroid transcription factor-1, CD31, Ki-67 and minichromosome maintenance protein 3. Expression level of t...

32 patients (19 female. 13 male)• suffering from graves' disease with exophthalmus and five without exophthalmus were studied for various autoantibodies including anti-thyroglobulin (atab). anti-microsomal antibody (amab). anti-parietal antibodies (apab) and also circulating immune complex (crc). 43 normal subjects were tested concurrently. immunofluorescent technique was employed for auto...
