Cerebral small vessel disease results in silent ischemic lesions (SIL) among which is leukoaraiosis. In this process, endothelial damage is probably involved. Endothelial progenitor cells (EPC), are involved in endothelial repair. By restoring the damaged endothelium, EPC could mitigate SIL and cerebral small vessel disease. Haptoglobin 1-1, one of three(More)
Cerebral small vessel disease (CSVD) is considered to be caused by an increased permeability of the blood-brain barrier and results in enlargement of Virchow Robin spaces (VRs), white matter lesions, brain microbleeds, and lacunar infarcts. The increased permeability of the blood-brain barrier may relate to endothelial cell activation and activated(More)
BACKGROUND AND PURPOSE Oxidized low-density lipoprotein (oxLDL) induces endothelial dysfunction and antibody formation. Because endothelial dysfunction is involved in cerebral small vessel disease (CSVD) (dilated Virchow Robin spaces, lacunar infarcts, and white matter lesions), oxLDL antibodies could play a role in CSVD pathogenesis. Therefore, we studied(More)
Recent studies in rodents indicate that the nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) inflammasome and a proinflammatory shift in the T cell population in adipose tissue (AT) contribute to AT inflammation and insulin resistance. We investigated: (1) the interplay between the NLRP3 inflammasome and T cell(More)
In experimental autoimmune myasthenia gravis anti-rat nicotinic acetylcholine receptor (AChR) antibody titers correlated significantly with the AChR-antibody complexes found in muscle. It was shown that at least a large part of the AChR-antibody complexes are formed in vitro, which can be prevented by washing of the muscle homogenate. Using a modified(More)
Anticardiolipin antibodies (aCLAs) and antibodies to oxidized-low density lipoproteins (oxLDL) are associated with two distinct diseases: the antiphospholipid syndrome and atherosclerosis. Because both diseases may be apparent in patients with systemic lupus erythematosus (SLE), it is important to establish the relationship between these two types of(More)
A panel of monoclonal antibodies (mAbs) against human thyroglobulin (hTg) was obtained by somatic fusion of the nonsecreting myeloma cell line P3X66 Ag8/0 and spleen cells of Balb/c mice immunized with purified hTg. Antibody secreting clones were selected by solid phase enzyme immunoassay and analyzed for cross-reaction with Tg from several animal species.(More)
An impaired vitamin D (vit-D) processing by immune cells of relapsing remitting multiple sclerosis (RRMS) patients may increase their vulnerability for a poor vit-D status. We assessed with qPCR the expression of vit-D related genes in PBMC and CD4+ T-cells. Gene expression profiles of vit-D receptor (VDR), CYP27B1 and CYP24A1 did not differ between RRMS(More)
Many patients surviving vasculitis are prone to accelerated atherosclerosis and often have enhanced levels of antibodies to oxidized low-density lipoprotein (oxLDL). To measure anti-oxLDL antibodies, oxidation of LDL is achieved with copper (Cu) or malondialdehyde (MDA). Because, in vivo, LDL may be oxidized with myeloperoxidase (MPO) or its product(More)
In humans and animal models of atherosclerosis, antibodies against oxidized LDL have been associated with atherosclerotic lesion development. It has been suggested that IgM anti-oxLDL antibodies are anti-atherogenic, whereas IgG anti-oxLDL antibodies are pro-atherogenic. In this study, we examined the relation between IgM and IgG antibody levels and(More)
