OBJECTIVE Autoantibodies against ribosomal P proteins are linked to the neuropsychiatric manifestations of systemic lupus erythematosus (SLE). The present study was undertaken to assess how the specific brain-binding autoantibody anti-ribosomal P can induce a depression-type psychiatric disorder in mice. METHODS Mice were injected(More)
Mice with experimental neuropsychiatric lupus (NPSLE), induced by anti-ribosomal-P antibodies, developed depression-like behavior and a diminished sense of smell. Manganese-enhanced MRI (MEMRI) allows in vivo mapping of functional neuronal connections in the brain, including the olfactory tract. The aim of this study was to analyze and describe, via the(More)
An autoantibody known as PL-7 was found in the serum of four patients with myositis and one with a systemic lupus erythematosus-like syndrome. The PL-7 antigen is an 80,000 dalton polypeptide that coprecipitates with transfer RNA. In aminoacylation reactions, PL-7 IgG inhibited the charging of tRNA with threonine but had little or no effect on charging with(More)
OBJECTIVE To examine in Sjögren's syndrome (SS) the interrelationship between the presence of the anti-Ro(SS-A) antibody response and (1) concomitant presence and type (ie, focal or nonfocal) of CNS disease (CNS-SS), (2) cross-sectional brain MRI or CT, and (3) abnormal cerebral angiography. METHODS Neurologic, neuroimaging, and angiographic features of(More)
Cross-idiotypic specificity has been demonstrated between antibody populations of different specificities using antibodies directed toward human sickle cell hemoglobin (HbS). A site-specific antibody directed toward the beta6-position of HbS, anti-Val, was used to elicit an anti-idiotypic response in rabbits. Using this anti-idiotypic serum, idiotypic(More)
Primary Sjögren's syndrome is an autoimmune disorder characterized by dryness of the mouth and eyes. The human leukocyte antigen (HLA) locus DQ is related to the primary Sjögren's syndrome autoantibodies that bind the RNA proteins Ro/SSA and La/SSB. Both DQ1 and DQ2 alleles are associated with high concentrations of these autoantibodies. An analysis of all(More)
Monoclonal anti-DNA antibodies prepared by the hybridoma technique were used for an analysis of idiotypes of anti-DNA antibodies in systemic lupus erythematosus (SLE). Serum levels of one idiotypic marker, 16/6/R, were higher than normal in 40 of 74 patients (54%) with active SLE, compared with only 6 of 24 patients (25%) with inactive SLE, 9 of 38 patients(More)
We previously demonstrated that purified polyclonal and monoclonal anti-dsDNA antibodies bind a 15-mer peptide ASPVTARVLWKASHV in ELISA and Dot blot. This 15-mer peptide partial sequence ARVLWKASH shares similarity with burkholderia bacterial cytochrome B 561 partial sequence ARVLWRATH. In this study, we show that purified anti-dsDNA antibodies react with(More)
The occurrence of idiotypic cross-reactivity between individuals of the same species has been demonstrated previously. This phenomenon was first observed with homogeneous human macroglobulins with cold agglutinin activity (1). Using antibodies of the same specificity, cross-idiotypic specificity has been observed in highly inbred strains of mice (2-7) and(More)
Sera from human patients with systemic lupus erythematosus (SLE) have been shown to react with snRNP particles of both mammals and Drosophila (Mount, S. M. and J. A. Steitz. 1981. Nucleic Acids Res. 9:6351-6368). We have utilized fully characterized monospecific sera and specifically purified antibodies to carry out indirect immunofluorescence experiments(More)
