NKp44 and NKp30 splice variant profiles have been shown to promote diverse cellular functions. Moreover, microenvironment factors such as TGF-β, IL-15 and IL-18 are able to influence both NKp44 and NKp30 splice variant profiles, leading to cytokine-associated profiles. Placenta and cancerous tissues have many similarities; both are immunologically privileged sites and both share immune tolerance mechanisms to support tissue development. Therefore, we studied the profiles of NKp44 and NKp30 splice variants in these states by comparing (i) decidua from pregnancy disorder and healthy gestation and (ii) matched normal and cancer tissue...

Newcastle disease (ND), caused by virulent strains of Newcastle disease virus (NDV), is a highly contagious disease of birds that is responsible for heavy economic losses for the poultry industry worldwide. However, little is known about host-virus interactions in waterfowl, goose. In this study, we aim to characterize the host immune response in goose, based on the previous reports on the host response to NDV in chickens. Here, we evaluated viral replication and mRNA expression of 27 immune-related genes in 10 tissues of geese challenged with a genotype VIId NDV strain of goose origin (go/CH/LHLJ/1/06)...

Muscle deconditioning is commonly observed in patients surviving sepsis. Little is known regarding the molecular mechanisms regulating muscle protein homeostasis during the recovery or convalescence phase. We adapted a sepsis-recovery mouse model that uses cecal ligation and puncture (CLP), followed 24 h later by cecal resection and antibiotic treatment, to identify putative cellular pathways regulating protein synthesis and breakdown in skeletal muscle. Ten days after CLP, body weight and food consumption did not differ between control and sepsis-recovery mice, but gastrocnemius weight was reduced...

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by aberrant T cell immune response. Diffuse proliferative lupus nephritis (LN-IV) is the most common, severe, and active form of lupus nephritis. In this study, we investigated the production of Th1, Th2, and Th17 cytokines in prediction of active form of LN-IV. ProcartaPlex multiplex immunoassays panels were used for detection of serum Th1, Th2, and Th17 cytokines profiling. Th1 and Th17 cytokines (IL-18, IFN-γ, IL-12p70, IL-6, and IL-17A) were considerably expressed in the serum of lupus nephritis IV patients in comparison to the healthy control...

Despite genetic heterogeneity, myelodysplastic syndromes (MDS) share features of cytological dysplasia and ineffective hematopoiesis. We report that a hallmark of MDS is activation of the NLRP3 inflammasome, which drives clonal expansion and pyroptotic cell death. Independent of genotype, MDS hematopoietic stem/progenitor cells (HSPC) overexpress inflammasome proteins and manifest activated NLRP3 complexes that direct activation of caspase-1, generation of IL-1β and IL-18 and pyroptotic cell death. Mechanistically, pyroptosis is triggered by the alarmin S100A9 that is found in excess in MDS HSPC and bone marrow plasma...

The interleukin-1 (IL-1) family consists of several pro- or anti-inflammatory proteins, with pro-inflammatory IL-1β being its best characterized member. IL-1β is one of the most prominent mediators of inflammation resulting in fever and immune activation via binding to IL-1 receptor 1. Due to its potency, its secretion is tightly regulated. First the transcription of the biologically inactive proform is induced by TLR activation, TNF, or IL-1 receptor activation by mature IL-1α or IL-1β. For the secretion of IL-1β, inflammasome activation as second stimulus is needed...

Vitamin B6 includes six water-soluble vitamers: pyridoxal (PL), pyridoxamine (PM), pyridoxine (PN), and their phosphorylated forms. Pyridoxal 5'-phosphate (PLP) is an important cofactor for many metabolic enzymes. Several lines of evidence demonstrate that blood levels of PLP are significantly lower in patients with inflammation than in control subjects, and that vitamin B6 has anti-inflammatory effects, with therapeutic potential for a variety of inflammatory diseases. Although one of our group (NK) previously demonstrated that PL inhibits the NF-κB pathway, the molecular mechanism by which vitamin B6 suppresses inflammation is not well understood...

Interleukin (IL) 6 and 18 plays an important role in inflammatory response following hypoxia ischemia encephalopathy (HIE). Present study was designed to demonstrate the effect of two GABAB receptor antagonists (CGP 35348 and 55845), respectively, on the serum IL6 and IL 18 concentrations in albino mice. Albino mice pups (of both genders) were subjected to Murine model of hypoxia-ischemia encephalopathy on postnatal day 10 (right common carotid artery was ligated followed by 8% hypoxia for 25 minutes). After neonatal brain damage and following weaning, mice were divided in three groups, in gender specific manner, and fed on normal rodent diet till they were 13 week old...

Excessive production of reactive oxygen species (ROS) induced by hyperglycemia increased the secretion of interleukin-1β (IL-1β), which contributes to the pathogenesis of diabetes and its complications. Although high glucose (HG)-induced oxidative stress and aberrant Ca(2+) channels activity causes an increase in transmembrane Ca(2+) influx, however the relative contribution of Transient receptor potential (TRP) channels is not well studied. Here, we identified that HG (30 mM glucose for 48 h) induced the activation of the NLRP3-ASC inflammasome, leading to caspase-1 activation, and IL-1β and IL-18 secretion in human monocytic cell lines...

One of the major causes of death in highly pathogenic avian influenza virus (HPAIV) infection in chicken is due to acute induction of pro-inflammatory cytokine (cytokine storm) which leads to severe pathology and acute mortality. Dendritic cells and macrophages of respiratory tract are the major antigen presenting cells (APCs) getting exposed to mucosal pathogens. We hypothesized that chicken dendritic cells might be a major target for H5N1 HPAIV for induction of cytokine dysregulation. Infection of chMoDCs with H5N1 HPAIV produced high titers of progeny virus with more rounding and cytotoxicity than H9N2 LPAIV...

Aberrant activation of the NOD-like receptor (NLR) family, pyrin domain-containing protein 3 (NLRP3) inflammasome, triggers a pathogenic inflammatory response in many inherited neurodegenerative disorders. Inflammation has recently been associated with valosin-containing protein (VCP)-associated diseases, caused by missense mutations in the VCP gene. This prompted us to investigate whether NLRP3 inflammasome plays a role in VCP-associated diseases, which classically affects the muscles, bones, and brain. In this report, we demonstrate (i) an elevated activation of the NLRP3 inflammasome in VCP myoblasts, derived from induced pluripotent stem cells (iPSCs) of VCP patients, which was significantly decreased following in vitro treatment with the MCC950, a potent and specific inhibitor of NLRP3 inflammasome; (ii) a significant increase in the expression of NLRP3, caspase 1, IL-1β, and IL-18 in the quadriceps muscles of VCP(R155H/+) heterozygote mice, an experimental mouse model that has many clinical features of human VCP-associated myopathy; (iii) a significant increase of number of IL-1β((+))F4/80((+))Ly6C((+)) inflammatory macrophages that infiltrate the muscles of VCP(R155H/+) mice; (iv) NLRP3 inflammasome activation and accumulation IL-1β((+))F4/80((+))Ly6C((+)) macrophages positively correlated with high expression of TDP-43 and p62/SQSTM1 markers of VCP pathology in damaged muscle; and (v) treatment of VCP(R155H/+) mice with MCC950 inhibitor suppressed activation of NLRP3 inflammasome, reduced the F4/80((+))Ly6C((+))IL-1β((+)) macrophage infiltrates in the muscle, and significantly ameliorated muscle strength...

Chronic obstructive pulmonary disease (COPD) is characterised by pulmonary and systemic inflammation that bursts during exacerbations of the disease (ECOPD). The NLRP3 inflammasome is a key regulatory molecule of the inflammatory response. Its role in COPD is unclear. We investigated the NLRP3 inflammasome status in: 1) lung tissue samples from 38 patients with stable COPD, 15 smokers with normal spirometry and 14 never-smokers; and 2) sputum and plasma samples from 56 ECOPD patients, of whom 41 could be reassessed at clinical recovery...

BACKGROUND: Inflammatory activity originating from the epicardial adipose tissue (EAT) may have a role in coronary artery disease (CAD) pathogenesis. The relationship between macrophage infiltration, polarization in the EAT, and netrin-1 gene expression was investigated. METHODS: Macrophage infiltration and polarization were examined by immunohistochemical methods and expression levels of netrin-1, Unc5b, and cytokines related with M1-macrophage subtype (IL-12 and IL-18) were determined by quantitative polymerase chain reaction in subcutaneous and epicardial adipose tissue obtained from patients undergoing coronary artery bypass grafting and non-coronary cardiac surgery...

Obesity is now recognised as a chronic, low-grade inflammatory disease contributing to insulin resistance, type 2 diabetes (T2D) and cardiovascular disease (CVD). Multiple mechanisms leading to the low grade inflammation in this setting have been suggested. Due to the complexity and interconnection of inflammatory and metabolic responses, there also remains a need to fully elucidate the inflammatory mechanisms that control obesity and associated metabolic disorders. One important avenue in the field that has gained great attention is the interleukin (IL)-1 superfamily of cytokines that consist of IL-1β, IL-18 and IL-33...

NOD-like receptor (NLR) proteins, as much as Toll-like receptor proteins, play a major role in modulating myeloid cells in their immune functions. There is still, however, limited knowledge on the expression and function of several of the mammalian NLR proteins in myeloid lineages. Still, the function of pyrin domain-containing NLR proteins and NLRC4/NAIP as inflammasome components that drive interleukin-1β (IL-1β) and IL-18 maturation and secretion upon pathogen stimulation is well established. NOD1, NOD2, NLRP3, and NLRC4/NAIP act as bona fide pattern recognition receptors (PRRs) that sense microbe-associated molecular patterns (MAMPs) but also react to endogenous danger-associated molecular patterns (DAMPs)...
