Physical activity confers a broad spectrum of health benefits. Beyond the obvious role in metabolically driven diseases, the role of physical activity in acute liver injury is poorly explored. To study the role of physical activity in acute liver injury, a novel model of voluntary distance running in mice was developed and mice were subjected to acute liver injury induced by N-galactosamine (GalN) and lipopolysaccharide (LPS). Analyses included histological stains, immunoblotting, qRT-PCR and FACS analysis...

Nucleotide-binding oligomerization domain containing 2 (NOD2)-induced signal transduction and cytokine production is regulated by a number of factors. However, the feedback effect of the pro-inflammatory TNF-α on NOD2-induced inflammation is not fully understood. In this study, we found unexpectedly that TNF-α up-regulated NOD2 ligand MDP-induced production of the CXC chemokines, including CXCL1, 2 and 8, and the pro-inflammatory cytokines, including IL-1β, IL-6 and TNF-α, in a dose-dependent manner at both mRNA and protein levels in monocytic THP-1 cells...

Following the acute phase of an inflammatory reaction, a strictly controlled resolution of inflammation is necessary. A dysregulation of this process leads to hyperinflammation, chronic inflammatory disease, or immune paralysis. Different mechanisms participate in the coordinated termination of the inflammatory process, e.g. the expression of antiinflammatory molecules and different forms of tolerance. To better understand the processes which mediate resolution of TNF-dependent inflammation and induce tolerance, it is necessary to characterize the signal transduction quality during TNF long-term (pre)incubation...

A20, a negative regulator of nuclear factor κB signaling, has been shown to attenuate atherosclerotic events. Transforming growth factor beta-activated kinase 1 (TAK1) plays a critical role in TNFα-induced atherosclerosis via endothelial nitric oxide (NO) synthase (eNOS) uncoupling and NO reduction. In the study, we investigated the hypothesis that A20 protected endothelial cell injury induced by TNFα through modulating eNOS activity and TAK1 signalling. Human umbilical vein endothelial cells (HUVECs) were stimulated by TNFα...

PURPOSE OF REVIEW: The review aims to summarize the recent findings in vasculitis that may have an impact in our understanding or management of these diseases. RECENT FINDINGS: We are learning more about monogenic diseases that closely mimic the pediatric vasculitides. Deficiency of adenosine deaminase 2 can present with a polyarteritis nodosa (PAN)-like picture and should be included in the differential of all pediatric cases of PAN with a family history or in cases with early stroke, or in cases resistant to conventional therapy...

The knowledge on systemic autoinflammatory disorders (SAID) is expanding rapidly and new signalling pathways are being decrypted. The concept of autoinflammation has been proposed since 1999, to define a group of diseases with abnormal innate immunity activation. Since then, more than 30 monogenic SAID have been described. In this review, we first describe inflammasomopathies and SAID related to the interleukin-1 pathway. Recent insights into the pathogenesis of familial Mediterranean fever and the function of Pyrin are detailed...

Interleukin-15 (IL-15) is a potent cytokine that increases CD8+ T and NK cell numbers and function in experimental models. However, obstacles remain in using IL-15 therapeutically, specifically its low potency and short in vivo half-life. To help overcome this, a new IL-15 superagonist complex comprised of an IL-15N72D mutation and IL-15RαSu/Fc fusion (IL-15SA, also known as ALT-803) was developed. IL-15SA exhibits a significantly longer serum half-life and increased in vivo activity against various tumors...

The human pathogen Helicobacter pylori infects more than half of the world's population and is a paradigm for persistent yet asymptomatic infection but increases the risk for chronic gastritis and gastric adenocarcinoma. For successful colonization, H. pylori needs to subvert the host cell death response, which serves to confine pathogen infection by killing infected cells and preventing malignant transformation. Infection of gastric epithelial cells by H. pylori provokes direct and fast activation of the proinflammatory and survival factor NF-κB, which regulates target genes, such as CXCL8, BIRC3 and TNFAIP3...

MiR-125b is aberrantly expressed and has a role in the various types of tumors. However, the role and mechanism of miR-125b in nasopharyngeal carcinoma (NPC) are unclear. In this study, we investigated the role and mechanism of miR-125b in NPC. We observed that miR-125b was significantly upregulated in the NPC tissues relative to normal nasopharyngeal mucosa (NNM), and its increment was correlated with poor patient survival, and was an independent predictor for reduced patient survival; miR-125b promoted NPC cell proliferation and inhibited NPC cell apoptosis; in a mouse model, administration of miR-125b antagomir significantly reduced the growth of NPC xenograft tumors...

The IL-17/IL-17R axis has controversial roles in cancer, which may be explained by tumor-specific results. Here, we describe a novel molecular mechanism underlying IL-17RC-controlled tumor-specific proliferation. Triggered by IL-17RC knockdown (KD), B16 melanoma and 4T1 carcinoma cells inversely altered homeostatic tumor proliferation and tumor growth in vitro and in vivo. In contrast to the existing dogma that IL-17RC-dependent signaling activates the JNK pathway, IL-17RC KD in both tumor cell lines caused aberrant expression and activation of different JNK isoforms along with markedly diminished levels of the ubiquitin-editing enzyme A20...

Inflammation is a key contributor to various types of acute and chronic liver disease. We recently reported that lack of Nur77, an orphan nuclear receptor, contributes to the pathogenesis of inflammatory diseases including inflammatory bowel disease and sepsis. However, whether Nur77 plays a critical role in liver inflammation remains to be fully understood. Employing in vivo acute liver inflammation model in wild-type (Nur77+/+) and Nur77-/- mice, we here found that Nur77 deficiency dramatically increased the production of pro-inflammatory cytokines and accelerated liver injury induced by Poly (I:C)/D-GalN in Nur77-/- mice...

Marsdenia tenacissima (MT), a traditional Chinese medicine, has been utilized in the treatment of a variety of malignant conditions for decades, but the underlying mechanism remains unclear. Angiogenesis, new blood vessel formation by nearby endothelial cells (ECs) from pre-existing vessels, plays a key role in cancer growth. In the present study, the effects of MT extract (MTE) on EC proliferation and apoptosis in vitro, and on A20 mouse lymphoma growth and angiogenesis in vivo were investigated. MTE exhibited an anti-proliferative effect on the ECs, with a half maximal inhibitory concentration of 11...

PURPOSE OF REVIEW: The growing awareness that the immune system is a key player in the antitumoral response and the excellent clinical results achieved in some settings with anti-programmed cell death 1 (PD1)/programmed death ligand 1 (PDL1) and anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA4) drugs has led to the rise of immunotherapy as a supplement or an alternative to conventional cancer treatment. The high costs associated with these therapies, their significant toxicity and the need to understand and circumvent immune escape mechanisms raise the urgent need for immunological assessment of therapy response...

Objective To investigate the effect of imatinib (IM) on the expressions of A20-binding inhibitor of NF-κB1 (ABIN1) and A20 in Jurkat T cells. Methods Jurkat T cells were treated with 25, 50 and 100 nmol/L IM for 24 hours. The mRNA and protein levels of ABIN1, A20 and NF-κB were detected by real-time quantitative PCR and Western blotting. Results IM significantly inhibited both mRNA and protein levels of ABIN1 and NF-κB, but raised the mRNA and protein levels of A20; while phorbol 12-myristate 13-acetate/ionomycin increased the expression levels of ABIN1 and A20 mRNA and protein...

BACKGROUND: Liver resection or partial hepatectomy (PH) is still the most commonly used therapeutic option for hepatocellular carcinoma (HCC) at present. However, the impaired regenerative ability induced by the accompanied liver cirrhosis is an important risk factor of posthepatectomy liver failure, and posthepatectomy liver failure is a feared complication that accounts for up to 75% of mortality after extensive liver resection. MicroRNA(miR)-203 is a tumor suppressor of HCC and may act as a positive intermediary in A20-enhanced interleukin (IL-6)/signal transducer and activator of transcription 3 (STAT3) pro-proliferative signals, which may promote liver regeneration after PH...

To determine the prevalence of human rhinovirus (HRV) infection in children with acute asthma exacerbations, investigation of HRV viral load and severity of asthma exacerbations is also required. Nasopharyngeal aspirates and swabs were collected and assessed for respiratory viruses. HRV-positive samples were sequenced to identify types and determine viral load. Outpatients with asthma exacerbations underwent follow-up evaluations, their swabs were collected and clinical outcomes were recorded at their next clinic visit 4 weeks later...

Reelin, a secreted glycoprotein, was recently demonstrated to be involved in the pathogenesis of cancer. However, its oncogenic activities in non-Hodgkin lymphoma (NHL) remain unclear. Therefore, we aimed to evaluate the functional role of reelin in NHL, and the underlying molecular mechanisms. In the present study, we analyzed reelin expression in lymphoma tissues and cell lines using immunohistochemistry, immunofluorescence staining, qRT-PCR and western blotting. Then, the expression of Reelin was silenced with short hairpin RNA (shRNA)-expressing plasmid in the NHL cell line A20...

REVIEW
Philip Cohen, Sam Strickson
The adaptor protein MyD88 is required for signal transmission by toll-like receptors and receptors of the interleukin-1 family of cytokines. MyD88 signalling triggers the formation of Lys63-linked and Met1-linked ubiquitin (K63-Ub, M1-Ub) chains within minutes. The K63-Ub chains, which are formed by the E3 ubiquitin ligases TRAF6, Pellino1 and Pellino2, activate TAK1, the master kinase that switches on mitogen-activated protein (MAP) kinase cascades and initiates activation of the canonical IκB kinase (IKK) complex...
