Experimental autoimmune uveitis (EAU) serves as a model for human autoimmune uveitis and for cell-mediated autoimmunity in general. EAU induced in mice by immunization with the retinal Ag interphotoreceptor retinoid-binding protein in CFA is driven by the Th17 response. Oral calcitriol (1,25-dihydroxyvitamin D(3)) prevented as well as partly reversed(More)
Immune privilege is used by the eye, brain, reproductive organs, and gut to preserve structural and functional integrity in the face of inflammation. The eye is arguably the most vulnerable and, therefore, also the most "privileged" of tissues; paradoxically, it remains subject to destructive autoimmunity. It has been proposed, although never proven in(More)
Artemisinin and its derivatives exhibit potent immunosuppressive activity. The aim of this study was to investigate the suppressive effects of SM905, a new water-soluble artemisinin derivative, on T lymphocytes both in vitro and in vivo, and explore its potential mode of action. The results showed that SM905 had a high inhibitory activity in Concanavalin A(More)
The performance of conventional minutiae-based fingerprint authentication algorithms degrades significantly when dealing with low quality fingerprints with lots of cuts or scratches. A similar degradation of the minutiae-based algorithms is observed when small overlapping areas appear because of the quite narrow width of the sensors. Based on the detection(More)
AIMS OF THE STUDY To investigate the neuroprotective effect of Lycium barbarum polysaccharide (LBP) on focal cerebral ischemic injury in mice and to explore its possible mechanism. MATERIALS AND METHODS Male ICR mice were used to make the model of middle cerebral artery occlusion (MCAO) after intragastric administration with LBP (10, 20 and 40 mg/kg) and(More)
ETHNOPHARMACOLOGICAL RELEVANCE Salvia miltiorrhiza has long been used in the traditional Chinese formulations for the treatment of heart ischemic diseases. AIM OF THE STUDY We investigated the cardioprotective effect of purified Salvia miltiorrhiza extract (SME) in an experimental model of acute myocardial infarction. MATERIALS AND METHODS Following(More)
AIM To study the immunosuppressive activity of SM735 {[3-(12-beta-artemisininoxy)] phenoxyl succinic acid}, a synthetic artemisinin derivative with nonsteroidal anti-inflammatory drug structure, with the aim of finding potential immunosuppressive agents. METHODS Concanavalin A (ConA), lipopolysaccharide (LPS), and mixed lymphocyte reaction (MLR), were(More)
BACKGROUND AND PURPOSE Resveratrol (RES) has been shown to prolong lifespan and prevent cancer formation. At present, the precise cellular mechanisms of RES actions are still not clearly understood, and this is the focus of this study. EXPERIMENTAL APPROACH Using human hepatocellular carcinoma-derived HepG2 cells as a model, we studied RES-induced changes(More)
The eye attempts to limit local immune and inflammatory responses to preserve vision. This phenomenon, known as ocular immune privilege, is mediated by a combination of local and systemic mechanisms. While immune privilege is believed to protect the eye from day-to-day inflammatory insults, it is not absolute and its mechanisms are still incompletely(More)
A series of triptolide analogs have been successfully synthesized. In the present study we demonstrated one of them, (5R)-5-hydroxytriptolide (LLDT-8), showed low cytotoxicity and relative high immunosuppressive activities as compared with its parent compound triptolide in vitro. The CC50 values of triptolide and LLDT-8 were 2.1+/-0.3 and 256.6+/-73.8 nM,(More)
