It has been suggested that toll-like receptor 4 (TLR4) promotes interleukin-10 (IL-10)-mediated cardiac cell survival while another receptor, TLR2, from the same family is detrimental. Here we examined the interactive role of these two innate signaling molecules under stressful conditions including interleukin-10 knockout (IL-10(-/-)) mice, global ischemia/reperfusion (I/R) injury in rat hearts and in-vitro shRNA experimental models in presence or absence of IL-10 (10ng/ml). Circulating and myocardial levels of tumor necrosis factor-α (TNF-α) as well as apoptosis and fibrosis were higher in IL-10(-/-) mice...

Antigen-presenting cells (APCs) play an important role in transplant rejection and tolerance. In high-risk corneal transplantation, where the graft bed is inflamed and vascularized, immature APCs in the donor corneal stroma quickly mature and migrate to lymphoid tissues to sensitize host T cells. In this study, using a mouse model of corneal transplantation, we investigated whether enrichment of tolerogenic APCs (tolAPCs) in donor corneas can enhance graft survival in corneal allograft recipients with inflamed graft beds...

Cucurbit[7]uril (CB7) is an uncharged and water-soluble macrocyclic host. CB7 binds to doubly protonated tuftsin, which is the tetrapeptide Thr-Lys-Pro-Arg, with moderate affinity (Ka=2.1×10(3)M(-1)). In this study, the host-guest complexation was confirmed by fluorescence titration. This affinity would allow for easy release of the peptide under physiological conditions. According to density functional theory calculations, the structural binding motif involves hydrogen bonding. The most energetically stable form had the Arg side chain inside the CB7 cavity...

The concerted activity of intestinal microbes is crucial to the health and development of their host organisms. Investigation of microbial interactions in the gut should deepen our understanding of how these micro-ecosystems function. Due to advances in Next Generation Sequencing (NGS) technologies, various bioinformatic strategies have been proposed to investigate these microbial interactions. However, due to the complexity of the intestinal microbial community and difficulties in monitoring their interactions, at present there is a gap between the theory and biological application...

Recent attention is focused on the impact of diet on health and mental well-being. High-salt and cholesterol diet (HSCD) is known to be associated with neuroinflammation which is the predominant factor for neurodegenerative disease like Alzheimer disease (AD). In the present study, we examined the neuroprotective potential of rosuvastatin, an HMG-CoA reductase inhibitor against HSCD induced neuroinflammation and cognitive impairment. Our results demonstrated that HSCD-induced cognitive impairment as determined by Morris water maze (MWM) task...

Glycogen synthase kinase (GSK)-3β has been known as a pro-inflammatory molecule in neuroinflammation. The involvement of GSK-3β remains unsolved in acute monophasic rat experimental autoimmune encephalomyelitis (EAE). The aim of this study was to evaluate a potential role of GSK-3β in central nervous system (CNS) autoimmunity through its inhibition by lithium. Lithium treatment significantly delayed the onset of EAE paralysis and ameliorated its severity. Lithium treatment reduced the serum level of pro-inflammatory tumor necrosis factor a but not that of interleukin 10...

The immune tolerance to the transplant heart survival is critical. Regulatory B cells are one of the major immune regulatory cell populations in the immune tolerance. Micro RNAs (miR) can regulate the activities of immune cells, such as the expression of interleukin (IL)-10 by B cells. This study tests a hypothesis that micro RNA (miR)-98 plays a role in the regulation of interleukin (IL)-10 expression in B cells (B10 cell) after heart transplantation. In this study, the peripheral blood samples were collected from patients before and after heart transplantation...

The etiological initiators of neuroinflammation remain inclusive, and effective interventions to block neurodegeneration are unavailable. Surprisingly, we found collagen II-combined complete Freund's adjuvant (CC) that usually induces rheumatoid arthritis (RA) also drives Alzheimer's disease (AD)-like neurodegeneration in mice. CC not only upregulates the cerebral pro-inflammatory cytokines including tumor necrosis factor α (TNF-α) and interleukin 8 (IL-8), but also downregulates the cerebral interleukin 10 (IL-10), an anti-inflammatory cytokine, and tyrosine hydroxylase (TH), a rate-limiting enzyme for biosynthesis of the anti-inflammatory neurotransmitter dopamine...

Primary immune thrombocytopenia (ITP) is an autoimmune disease with many immune dysfunctions including T helper type 1 cell (Th1) polarization and regulatory T cells (Tregs) deficiency. This study aimed to determine the effects of TLR4 on Treg differentiation and the cytokine production of peripheral blood mononuclear cells (PBMCs) from patients with ITP. We found that expression of TLR4 on monocytes was significantly decreased in patients with active ITP than that in healthy controls and it had positive correlation with platelet count...

BACKGROUND: Interleukin-10 secreting B-cells are a major subset of B-regulatory cells (B-regs), commonly recognized as CD19(+)/38(hi)/24(hi)/IL10(+). They carry out immunomodulation by release of specific cytokines and/or cell-to-cell contact. We have generated B-regs in-vitro from donor adipose tissue derived mesenchymal stem cells (AD-MSC) and renal allograft recipient (RAR) peripheral blood mononuclear cells (PBMC) for potential cell therapy. MATERIAL AND METHODS: Mononuclear cells separated by density gradient centrifugation from 50 ml anti-coagulated blood of 15-RAR and respective donors were analysed for baseline B-regs using appropriate antibodies...

Dendritic cells (DC) have the potential to instigate a tumour-specific immune response, but their ability to prime naïve lymphocytes depends on their activation status. Thus, for tumour immunotherapy to be effective, the provision of appropriate DC activation stimuli such as Toll-like receptor (TLR) agonists is crucial in order to overcome immunosuppression associated with the tumour microenvironment. To address this, we investigated how ovarian carcinoma (OC)-associated ascites impedes activation of DC by TLR agonists...

Chronic periodontitis is caused by an inflammatory reaction of the periodontal tissues and alveolar bone. This inflammation is caused by periodontopathic bacteria located in the subgingival biofilm, resulting in inflammatory reactions that may lead to loss of attachment. This tissue destruction is a consequence of host immune and inflammatory responses to specific periodontal pathogens and their metabolic products. Cytokines modulate the immune response, altering its efficiency in the competition against pathogens and increasing periodontal susceptibility...

Hypoxia is a common cause of kidney injury and a major issue in kidney transplantation. Mitogen-activated protein kinases (MAPKs) are involved in the cellular response to hypoxia, but the precise roles of MAPKs in renal cell reaction to hypoxic stress are not well known yet. This work was conducted to investigate the regulation of ERK1/2 and p38 and their signaling-relevant molecules in kidney epithelial cells exposed to prolonged hypoxia. Rat kidney epithelial cells NRK-52E were exposed to hypoxic conditions (1% O2) for 24-72 hrs...

The purpose of the research was to explore the therapeutic action of simvastatin-loaded poly(ethylene glycol)-b-poly(gamma-benzyl l-glutamate) (PEG-b-PBLG50) on intestinal ischemia/reperfusion injury (II/RI) through downregulating bone morphogenetic protein 4 (BMP4)/cyclooxygenase-2 (COX-2) pathway as compared to free simvastatin (Sim). Sprague Dawley rats were preconditioned with 20 mg/kg Sim or simvastatin/PEG-b-PBLG50 (Sim/P) compounds, and then subjected to 45 min of ischemia and 1 h of reperfusion. The blood and small intestines were collected, serum levels of interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α, and nitric oxide (NO) were checked, and the dry/wet intestine ratios, superoxide dismutase activity, myeloperoxidase content, reactive oxygen species, endothelial nitric oxide synthase, protein 47 kDa phagocyte oxidase (p47phox), BMP4, COX-2, and p38 mitogen-activated protein kinase (p38MAPK) expressions were measured in intestinal tissues...

BACKGROUND: Recently, the d-galactose (d-gal)-induced mimetic aging rat model has been widely used in studies of age-associated diseases, which have shown that chronic d-gal exposure induces premature aging similar to natural aging in rats. With the increasing rate of sepsis in the geriatric population, an easy-access animal model for preclinical studies of elderly sepsis is urgently needed. This study investigates whether a sepsis model that is established in d-gal-induced aging rats can serve as a suitable model for preclinical studies of elderly patients with sepsis...
