Factors affecting excretion of human urinary Tamm-Horsfall glycoprotein.
1. Tamm-Horsfall glycoprotein was determined, by radioimmunoassay, in samples of urine from normal individuals under a variety of physiological conditions. 2. The amount of glycoprotein excreted in 24 h by our population (39 +/- 13 mg, corrected for body surface area) was found not to be influenced by sex, age (19-60 years) or amounts of Ca2+, Mg2+ and Na+ excreted. 3. Urine samples collected a...
متن کاملImmunomodulatory properties of Tamm-Horsfall glycoprotein (THP) and uromodulin.
BACKGROUND Tamm-Horsfall glycoprotein (THP) and uromodulin are the most abundant glycoproteins in non-pregnant women's/men's and pregnant women's urine, respectively. However, the bioactivities of these glycoproteins are still unclear. OBJECTIVE To evaluate the immunomodulatory properties of THP and uromodulin on human peripheral blood mononuclear cells (PBMC) METHODS: THP and uromodulin isol...
متن کاملEvaluation of Glycan Profiles of Tamm-horsfall Glycoprotein and Uromodulin
Uromodulin is well-known to be the more potent immunosuppressive glycoprotein isolated from pregnant women urine, compared to its counterpart, Tamm-Horsfall glycoprotein (THP) isolated from non-pregnant women/male urine. However, structural profiles of these glycoproteins were controversial until today. Hence, this paper aims to identify the pregnancy associated glycosylation changes of THP and...
متن کاملTamm-Horsfall urinary glycoprotein. The chemical composition.
1. A revised amino acid and carbohydrate composition of human Tamm-Horsfall glycoprotein is presented. 2. No significant differences were obtained in the amino acid composition of Tamm-Horsfall glycoprotein isolated from patients with cystic fibrosis. 3. The glycoprotein was shown to possess a high half-cystine content of 1 per 11-12 amino acid residues, which has been confirmed by performic ac...
متن کاملDefective expression of Tamm-Horsfall protein/uromodulin in COX-2-deficient mice increases their susceptibility to urinary tract infections.
Mice lacking a functional cyclooxygenase-2 (COX-2) gene develop abnormal kidneys that contain hypoplastic glomeruli and reduced proximal tubular mass, and they often die of renal failure. A comparison of kidney-specific gene expression between wild-type and COX-2-deficient mice by cDNA microarrays revealed that although more than 500 mRNAs were differentially expressed between the two strains o...
