High mobility group box-1 (HMGB1) protein was originally characterized as a nuclear DNA-binding protein, and described to have an extracellular role when involved in cellular activation proinflammatory responses. In the present study, we found that activity of recombinant HMGB1 proteins is determined by containing endotoxin level, contains few endotoxins fails stimulate macrophages secrete cytokines. acts ligand receptor for advanced glycation end products (RAGE) works synergy with LPS...

Rheumatoid arthritis (RA) is a complex and not fully understood autoimmune disease associated with multijoint damage. The main effector cells, the synovial fibroblasts, are apoptosis resistant hyperplastic which indicate that autophagy level high in tissue. Real-time PCR, immunocytochemistry, western blotting were used this paper to study status of tissues obtained from RA OA patients at time joint replacement surgery. We further evaluated correlation between levels activity-associated serum...

It is generally believed that some inflammatory antigens can recognize Toll-like receptors on synovial fibroblasts (SFs) and then activate downstream signals, leading to the formation of RASFs inducing rheumatoid arthritis (RA). The objective current work was study hypothesis outer PAMP (LPS) binds inner DAMP (HMGB1) becomes a complex recognizes TLRs/RAGE SFs, thus initiating signaling cascade leads secretion cytokines chemokines, production tissue-destructive enzymes, RASFs, finally...

Abstract IL -10 is widely accepted as a survival, proliferation, and differentiation factor for B cells. However, IL-10 deficiency accelerates disease progression the result of autoantibody production in many autoimmune models. It was demonstrated that T follicular helper cells (TFH cells) play key role helping are secreting Abs. In this study, we regulatory IL-10R signaling on development cell help function TFH vitro vivo. IL-1R subunit β-deficient (Il10rb−/−) Th were able to differentiate...

Synovial fibroblasts (SF) play a central role in the inflammatory and destructive process rheumatoid arthritis (RA). High-mobility group box chromosomal protein 1 (HMGB1) or lipopolysaccharide (LPS) alone failed to induce significant changes proliferation of cultured SF from RA patients, but premixed HMGB1 with LPS (HMGB1-LPS) significantly facilitated proliferation. IL-6, MMP-3, MMP-13 production greatly enhanced LPS-induced expression at both mRNA levels. HMGB1-LPS synergistically...

The P. falciparum chimeric protein 2.9 (PfCP-2.9) consisting of the sequences MSP1-19 and AMA-1 (III) is a malaria vaccine candidate that was found to induce inhibitory antibodies in rabbits monkeys. This phase I randomized, single-blind, placebo-controlled, dose-escalation study evaluate safety immunogenicity PfCP-2.9 formulated with novel adjuvant Montanide ISA720. Fifty-two subjects were randomly assigned 4 dose groups 10 participants, each receiving test 20, 50, 100, or 200 microg...

Background:Circulating microRNA (miRNA) are promising biomarkers for diagnosing and prognosticating numerous diseases. Reports have demonstrated controversial or even contradictory conclusions in studies on circulating microRNA. This study aimed to evaluate the potential bias of using different reference genes analyzing microRNAs same malignant digestive Material andMethods:We measured plasma concentrations U6-snRNA, let-7a, miRNA-21, miRNA-106a, miRNA-155, miRNA-219, miRNA-221, miRNA-16...

Abstract Excessive activation of TLR may induce endotoxin shock and inflammatory diseases, so the negative regulation TLR-triggered response attracts much attention. Nonpathogenic immune complex (IC) Ig (IC/Ig) have been shown to play important roles in responses be therapeutic some kinds autoimmune diseases. However, role IC/Ig underlying mechanisms remain fully understood. In this study we demonstrate that can significantly inhibit LPS-induced secretion TNF-α IL-6 from macrophages by...

In this work, we aimed to investigate the frequency, possible categories and clinical significance of circulating CD4 + ICOS FoxP3 T cells in patients with systemic lupus erythematosus (SLE). The frequency was analysed by flow-cytometric analysis 32 SLE patients, 10 rheumatoid arthritis healthy controls. Production IL-10 mTGF-β different T-cell populations determined intracellular cytokine staining. Plasma levels TGF-β were enzyme-linked immunosorbent assay (ELISA). significantly increased...

Abstract Hepatitis B surface antigen (HBsAg) and anti‐HBs antibodies (anti‐HBs) may coexist in certain chronic hepatitis (CHB) patients. This study was designed to further explore the relationship between this coexistence Virus (HBV) preS deletions. Sera of 28 patients carrying both HBsAg (Group I) those another positive but negative II) were collected from CHB Direct sequencing polymerase chain reaction products or clones applied groups determine sequences HBV S genes.

A balance of inhibitory and activating signals determines the function dendritic cells (DCs) in immune response, which may be regulatory or stimulatory. Defects receptor FcγRIIb are involved pathogenesis autoimmune diseases such as systemic lupus erythematosus (SLE), high levels circulating complexes (IC) exist. Our previous study showed that IC/Ig can suppress TLR4-triggered inflammatory responses macrophages via FcγRIIb. This led us to question whether polarize FcγRIIb-overexpressing DCs...

The AQP5 gene located human chromosome 12q, same region as location major asthma susceptibility loci. In this study we try to determine whether knock-out has some effect on allergen-induced asthma. With mouse model induced by ovalbumin (OVA), found that deletion reduced characteristic features asthma, such less...
