Solution at 2.5-A resolution of the three-dimensional structure of H-2Ld with a single nine-residue peptide provides a structural basis for understanding its unique interaction with beta-2 microglobulin (beta2m) and peptide. Consistent with the biological data that show an unusually weak association of Ld with beta2m, a novel orientation of the alpha1/alpha2 domains of Ld relative to beta2m res...
GUIDELINE RECOMMENDATIONS • We recommend that either synthetic or cellulosic membranes be used for symptomatic intra-dialytic hypotension as synthetic membranes offer no benefit over cellulosic membranes (1C). • We recommend that high-flux membranes be used to remove molecules such as beta-2 microglobulin because they have been shown to achieve lower serum levels (1A). • We suggest there are po...
We determined serum concentrations of neopterin and beta 2-microglobulin, soluble markers of cellular immune activation, in 27 patients with either dilated cardiomyopathy (DCM) or chronic myocarditis. Neopterin and beta 2-microglobulin concentrations were respectively increased in 2 and 5 of 11 patients with DCM and in 11 and 9 of 16 patients with chronic myocarditis. A higher cardiac functiona...
BACKGROUND Autoimmune disorders often develop during the course of B chronic lymphocytic leukemia. The source of the autoantibodies is still uncertain: either uncontrolled production of the malignant B cells or disturbances of the residual normal B and T cells involved in the immune system. OBJECTIVES To evaluate immunologic parameters in B-CLL associated with autoimmune disorders. As a hypot...
BACKGROUND The aim of the study was to assess the relationships among serum neopterin (NPT), β2-microglobulin (β2-M) levels, clinical status, and endomyocardial biopsy results of dilated cardiomyopathy patients (DCM). METHODS Serum NPT and β-2 M were determined in 172 nonischaemic DCM patients who underwent right ventricular endomyocardial biopsy and 30 healthy subjects (ELISA test). The cryo...
Monoclonal antibody TG1 recognizes specifically antigens HLA-B27, B7, B22 and B17 on cell surface in cytotoxicity and cytofluorometry tests. When cell detergent extracts were subjected to SDS PAGE under mild conditions (no heating and no reduction of the sample) followed by Western blotting, TG1 detected exclusively a complex of B27 heavy chains with beta(2)-microglobulin (as a 50 kDa band) whe...
COS7 (African Green Monkey kidney) cells stably transfected with the mouse MHC class I allele H-2K(b) were mutagenized, selected for low surface expression of endogenous MHC class I products, and subcloned. A mutant cell line, 4S8.12, expressing very low surface MHC class I (approximately 5% of parental levels) was identified. This cell line synthesized normal levels of the MHC class I H chain ...
A low molecular weight beta(2)-globulin (beta(2)-microglobulin), albumin, and total protein were measured in concentrated 24-hr urine specimens from 20 healthy subjects and 30 patients with clinical proteinuria of glomerular or tubular type. Classification of proteinuria was made on the basis of clinical diagnosis and size distribution of urinary proteins after gel chromatography. The molecular...
