The inflammatory response of glial cells contributes to neuronal damage or repair after brain ischemia/reperfusion insult. We previously demonstrated a protective role of TP53-induced glycolysis and apoptosis regulator (TIGAR) in ischemic neuronal injury through increasing the flow of pentose phosphate pathway (PPP). The present study investigated the possible role of TIGAR in ischemia/reperfusion-induced inflammatory response of astrocytes. Male ICR mice were subjected to middle cerebral artery occlusion for 2 h followed by 24 h reperfusion and cultured primary astrocytes were subjected to oxygen glucose deprivation for 9 h followed by 24 h reoxygenation (OGD/R)...

Cryopyrin-associated periodic syndrome (CAPS) is caused by a mutation in the NLRP3 gene encoding cryopyrin production. Overproduction of interleukin-1 (IL-1) leads to symptoms that are associated with elevated inflammatory markers, including periodic fever and a rash. We provide a clinical overview of CAPS in children, including three Finnish case studies. Conclusion When CAPS has been diagnosed, an IL-1 blockade with biologicals should be introduced to lessen the symptoms and to prevent the progression of organ damage...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a non-specific inflammation, which involves the airways, lung parenchyma and pulmonary vessels. The inflammation causes the activation of inflammatory cells and the release of various inflammatory mediators such as interleukin-1 beta, interleukin-6 and tumor necrosis factor alpha (TNF-a). The present study was designed to assess the serum cytokines [Interleukin-1β (IL-1β), Interleukin-6 (IL-6), Tumor necrosis factor-α (TNF-α)] levels in chronic obstructive pulmonary disease (COPD) patients and they were correlated with severity of disease by spirometric measurements...

Objective Temporomandibular joint dysfunction (TMD) may affect a patient's quality of life, and one of the etiologies can be anterior disc displacement with reduction (ADDwR) and anterior disc displacement without reduction (ADDWoR). Interleukin 1 Receptor 1 (IL-1R1) is a membrane receptor that plays an important role on initiating immune and inflammatory response by binding the agonists ligands of IL-1 alpha and IL-1 beta. Therefore, the aim of this study was to evaluate, through immunohistochemical analysis, the association of IL-1R1 with TMD...

Many studies have shown that stress-induced cortisol levels negatively influence growth and immunity in finfish. Despite this knowledge, few studies have assessed the direct effects of cortisol on liver immune function in finfish. Using real-time PCR, the expression of three cortisol-responsive genes (GR: glucocorticoid receptor, IGF-1: insulin-like growth factor-I and SOCS-1: suppressor of cytokine signaling-I), genes involved with innate and adaptive immunity (IL-1β: interleukin-1 beta, IgM: immunoglobin-M and Lyz: lysozyme), and liver-specific antimicrobial peptides (hepcidin and LEAP-2A: liver-expressed antimicrobial peptide-2A) were studied in vitro using rainbow trout liver slices...

Microvesicles (MVs) are emerging as a new mechanism of intercellular communication by transferring cellular components to target cells, yet their function in disease is just being explored. However, the therapeutic effects of MVs in cartilage injury and degeneration remain unknown. We found MVs contained high levels of sphingosine-1-phosphate (S1P) compared with the original bone marrow mesenchymal stem cells (MSCs). The enrichment of S1P in MVs was mediated by sphingosine kinase 1 (SphK1), but not by sphingosine kinase 2 (SphK2)...

Micro(mi)RNAs are small, non-coding RNA molecules known to play a significant role in osteoarthritis (OA) initiation and development, and similar to matrix metalloproteinases (MMPs), they participate in cartilage degeneration and cleave multiple extracellular matrices. The aim of this study was to determine whether the expression of MMP-19 in interleukin (IL)-1β-induced human chondrocytes is directly regulated by miR-193b-3p. Expression levels of miR-193b-3p and MMP-19 in normal and osteoarthritis (OA) human cartilage, and interleukin-1 β (IL-1β)-induced human chondrocytes were determined by real-time polymerase chain reaction...

BACKGROUND: Doxorubicin (DOX) is commonly used in the treatment of many types of cancers but its cardiotoxicity is limiting its clinical use. Beyond its anticoagulant action, enoxaparin (ENX), a low molecular weight heparin, has been shown to exert multiple pharmacological actions including antioxidant, anti-inflammatory and antiapoptotic effects. Therefore, the current study aimed to assess if ENX could ameliorate cardiotoxicity induced by DOX. METHODS: Twenty-one adult male Wistar albino rats were randomly allocated into three groups (n = 7 each) of control, receiving 0...

Staphylococcus aureus (SA) nasal carriage is transient in most humans and usually benign, but dissemination of SA to extranasal sites causes the majority of clinical infections, and SA is a major cause of serious infections in the U.S. A better understanding of innate nasal decolonization mechanisms is urgently needed, as are relevant models for studying SA clearance. Here, we screened a population of healthy smokers for nasal SA carriage, and compared participants' abilities to clear experimentally applied nasal SA before and after completion of a smoking cessation program...

BACKGROUND: Lipoprotein(a) [Lp(a)] is a genetic risk factor for cardiovascular disease (CVD), and proinflammatory interleukin-1 (IL-1) genotypes may influence Lp(a)-mediated CVD events. The genotype IL-1(+) is associated with higher rates of inflammation than IL-1(-) genotype. Targeting IL-1β was recently shown to decrease CVD events independent of low-density lipoprotein-cholesterol levels. OBJECTIVE: The objective of the study is to assess the modulatory effect of IL-1 genotypes on risk mediated by Lp(a) METHODS: We assessed whether IL-1 genotypes modulate the effect of Lp(a) on major adverse cardiovascular events (cardiovascular death, myocardial infarction, and stroke/transient ischemic attack) and angiographically determined coronary artery disease (CAD)...

Extracellular interleukin 1 alpha (IL-1α) released from keratinocytes is one of the endpoints for in vitro assessments of skin irritancy. Although cells dying via primary skin irritation undergo apoptosis as well as necrosis, IL-1α is not released in apoptotic cells. On the other hand, active secretion has been identified in interleukin-1 receptor antagonist (IL-1ra), which was discovered to be a common, upregulated, differentially-expressed gene in a microarray analysis performed with keratinocytes treated using cytotoxic doses of chemicals...

Osteoarthritis (OA) is the most common joint disease and is mainly characterized by degradation of the articular cartilage. Recently, circular RNAs (circRNAs), novel noncoding RNAs with different biological functions and pathological implications, have been reported to be closely associated with various diseases. Growing evidence indicates that circRNAs act as competing endogenous RNAs (ceRNAs) that bind with microRNAs (miRNAs) and regulate their downstream functions. Here, we identified a new circRNA, circRNA_Atp9b, and further investigated its function in OA using a well-established mouse chondrocyte model...

Here, we report thyroid transcription factor 1 (TTF-1) as an important transcription factor for the expression of heme oxygenase-1 (HO-1). HO-1 is a well-known cytoprotective enzyme against inflammation. We observed that HO-1 co-expressed with TTF-1 in mouse hypothalamic cells. Results from luciferase and chromatin immunoprecipitation assays revealed that TTF-1 directly activated HO-1 transcription by binding to binding domains in the 5'-flanking region of the HO-1 gene. A proinflammatory cytokine, tumor necrosis factor-alpha (TNF-α), induced nuclear translocation of TTF-1 and increased binding affinity of TTF-1 to its binding sites on the HO-1 gene...

BACKGROUND: Cognitive impairment is one of common complications of acute respiratory distress syndrome (ARDS). Increasing evidence suggests that interleukin-1 beta (IL-1β) plays a role in inducing neuronal apoptosis in cognitive dysfunction. The lung protective ventilatory strategies, which serve to reduce pulmonary morbidity for ARDS patients, almost always lead to hypercapnia. Some studies have reported that hypercapnia contributes to the risk of cognitive impairment and IL-1β secretion outside the central nervous system (CNS)...

TiO₂ nanotubes (TNT) formation is beneficial for improving bone cell-material interaction and drug delivery for Ti dental implants. Among the natural drugs to be installed in TNT, selected propolis has antibacterial and anti-inflammatory properties. It is a resinous natural product which is collected by the honeybees from the various types of plants with their salivary enzymes. This study concludes that TNT loaded with a propolis (PL-TNT-Ti) dental implant has the ability to improve osseointegration. The propolis particles were embedded within the TNT or adhered to the top...
