OBJECTIVE To analyze the presence and specificity of anti-alpha-enolase antibodies in various systemic autoimmune diseases. METHODS Sera from patients with systemic lupus erythematosus (SLE), mixed cryoglobulinemia (MC), systemic sclerosis (SSc), and rheumatoid arthritis (RA) were tested by immunoblot on partially purified a-enolase from human kidney and(More)
BACKGROUND Autoantibodies to citrullinated proteins (ACPA) are considered a specific marker for rheumatoid arthritis. Peptidylarginine deiminase (PAD) is the enzyme that converts arginyl into citrullyl residues; different isoforms of the enzyme are expressed in mammals. It has been suggested that the PADI4 gene may contribute to genetic susceptibility to(More)
In this paper, we propose an absolutely innovative technique for the electrical stimulation of cells, based on piezoelectric nanoparticles. Ultrasounds are used to impart mechanical stress to boron nitride nanotubes incubated with neuronal-like PC12 cells. By virtue of their piezoelectric properties, these nanotubes can polarize and convey electrical(More)
Anti-DNA antibodies and anti-endothelial cell antibodies (AECA) are often detected in systemic lupus erythematosus (SLE). Anti-DNA antibodies can also bind the membrane of human umbilical vein endothelial cells (HUVEC), but little is known about the presence of AECA in the population of immunoglobulins from SLE sera that do not bind DNA. The aim of this(More)
Thanks to a non-covalent wrapping with glycol-chitosan, highly biocompatible and highly concentrated dispersions of boron nitride nanotubes were obtained and tested on human neuroblastoma cells. A systematic investigation of the cytotoxicity of these nanovectors with several complementary qualitative and quantitative assays allowed a strong interference(More)
In systemic autoimmune diseases, autoantibodies specific for alpha-enolase are detected more frequently in patients with active renal involvement. To analyze the properties of anti-alpha-enolase antibodies and the distribution of the enzyme in the cell, mouse monoclonal and polyclonal antibodies were obtained from mice immunized with a(More)
The analysis of myenteric neurons is becoming increasingly important for the assessment of enteric nervous system injury and degeneration occurring in motor disorders of the gut. Limited information is presently available on the quantitative estimation of myenteric neurons and glial cells in paraffin-embedded colonic sections; additional data would be(More)
The purpose of the present study was to establish a method for light microscopical immunohistochemical localization of the small G protein RhoA on specimens treated and embedded for routine transmission electron microscopy. There are advantages in antigen immunolocalization on resin semi-thin sections compared to cryostat or paraffin sections: the(More)
In situ formation of immune complexes is a well recognized mechanism of renal injury in systemic autoimmune disorders. The identification of intrinsic renal antigens that are targets of nephritogenic antibodies is a field of active investigation. Recently, two proteins expressed in the kidney have been characterized as renal antigens. Alpha-actinin, an(More)
Boron nitride nanotubes (BNNTs) have generated considerable interest within the scientific community by virtue of their unique physical properties, which can be exploited in the biomedical field. In the present in vitro study, we investigated the interactions of poly-l-lysine-coated BNNTs with C2C12 cells, as a model of muscle cells, in terms of(More)
