Patients with liver cirrhosis are susceptible to infections with high short-term mortalities. One CD97-related EGF-TM7 molecule, EMR2 (EGF-like molecule containing mucin-like hormone receptor 2), had been shown to regulate human neutrophil function, potentiate systemic inflammation. Nevertheless, EMR2 could also suppress neutrophil survival. Studying the role of EMR2 on neutrophil would be intriguing. 48 healthy volunteers and 100 cirrhotic patients were enrolled. Neutrophils were isolated from peripheral blood and cell surface markers were measured by flow cytometry...

The acute phase proteins are biochemically and functionally unrelated protein predominantly synthesized in the liver. The local inflammatory cells i.e. macrophages and neutrophils secretes various cytokines like IL-1, IL-6, IL-8 (interleukins) and TNF-α into bloodstream in response to injury and tissue damage, which stimulate hepatocytes to produce protein and release them into the circulation; these proteins are called as acute phase protein (e.g. C-reactive protein (CRP), serum amyloid A (SAA), metal binding protein, lysozyme, lectin, etc...

REVIEW
Feliciano Chanana Paquissi
Non-alcoholic fatty liver disease (NAFLD) is an increasing problem worldwide and is associated with negative outcomes such as cirrhosis, hepatocellular carcinoma, insulin resistance, diabetes, and cardiovascular events. Current evidence shows that the immune response has an important participation driving the initiation, maintenance, and progression of the disease. So, various immune imbalances, from cellular to cytokines levels, have been studied, either for better compression of the disease pathophysiology or as biomarkers for severity assessment and outcome prediction...

BACKGROUND: Prediction of hepatorenal syndrome (HRS) remains difficult in advanced cirrhotic patients. AIMS: To evaluate use of serum and urine biomarkers to predict HRS. METHODS: We prospectively recruited Child's B or C cirrhotic patients with normal serum creatinine, and followed them for 12 weeks for the development of HRS. Serum Cystatin C (CysC), serum and urine Neutrophil Gelatinase-Associated Lipocalin (NGAL), serum and urine IL-18, serum N-acetyl-β-d glucosaminidase (NAG), urine kidney injury molecule-1 (KIM-1) and urine liver-type fatty acid binding protein (LFABP) were measured at recruitment (baseline), and their relationship with subsequent HRS investigated...

In a previous study, 15-nm silica nanoparticles (NPs) caused small increases in DNA damage in liver as measured in the in vivo comet and micronucleus assays after intravenous administration to rats at their maximum tolerated dose, a worst-case exposure scenario. Histopathological examination supported a particle-induced, tissue damage-mediated inflammatory response. This study used a targeted approach to provide insight into the mode of action (MoA) by examining transcriptional regulation of genes in liver in a time and dose-dependent manner at 1, 2, 4, 8 and 24 h after intravenous administration of 15-nm silica NPs...

Real-life data showed an increased incidence of bacterial infections in patients with advanced liver disease receiving a protease inhibitor (PI)-containing antiviral regimen against hepatitis C (HCV). However, the causes of this event are unknown. We hypothesized that PIs might impair innate immune responses through the inhibition of proteases participating in the anti-bacterial functions of neutrophils and monocytes. The aims of the study were to assess phagocytic and oxidative burst capacity in neutrophils and monocytes obtained from patients receiving a PI containing-antiviral regimen, and to determine cytokine secretion after neutrophil stimulation with flagellin...

BACKGROUND: Activated leukocytes infiltrating the liver contribute to the provocation of alcoholic hepatitis. Glucocorticoid induces the demargination of leukocytes from the hepatic sinusoids, whereas granulocyte-monocyte absorptive apheresis (GMA) removes leukocytes from the circulation. Thus, the usefulness of a sequential therapy consisting of glucocorticoid infusions followed by GMA was evaluated in patients with severe alcoholic hepatitis. METHODS: Patients with severe alcoholic hepatitis received intravenous injections of methylprednisolone (1,000 mg/day) for 3 or 4 days, and then GMA was performed every day for 3 days...

Alpha-1 antitrypsin (A1AT) is a 52-kDa, acute phase glycoprotein encoded by the protease inhibitor (PI) locus, located on the long arm of chromosome 14 (14q31-32.3). Its structure is composed of a total of 7 exons, 4 coding (II, III, IV, and V) and 3 non-coding (Ia, Ib, and Ic). A1AT is produced primarily by hepatocytes and acts as a serine protease inhibitor with anti-protease and immunoregulatory activities. The main target of A1AT is neutrophil elastase (NE), an enzyme released during a neutrophil-mediated inflammatory process...

Identifying intended or accidental cellular targets for drug delivery systems is highly relevant for evaluating therapeutic and toxic effects. However, limited knowledge exists on the distribution of nano- and micrometer-sized carrier systems at the cellular level in different organs. We hypothesized that clinically relevant carrier materials, differing in composition and size, are able to target distinct myeloid cell subsets that control inflammatory processes, such as macrophages, neutrophils, monocytes and dendritic cells...

BACKGROUND: Recent evidence indicates that inflammatory parameters could be useful to predict metastasis from colorectal cancer. However, their roles in predicting chemotherapy response and prognosis in patients with synchronous colorectal liver metastasis (CLM) are unknown. METHODS: The clinical data and baseline laboratory parameters of 55 patients with synchronous CLM were retrospectively reviewed. All patients underwent palliative resection of the primary tumor and oxaliplatin-based chemotherapy...

Phospholipase D-2 (PLD2) has a key role in breast cancer formation and metastasis formation with PLD small inhibitors reducing primary tumor growth. This study aimed to evaluate the importance of targeting PLD on the tumor microenvironment. We provide evidence about the beneficial effect of PLD inhibitors [FIPI (dual PLD1/PLD2) or VU0155072-2 (PLD2 inhibitor)] on avoiding infiltration of tumor-helping macrophages and neutrophils. Tumor growth and metastasis within the primary tumors had low (<20% over controls) PLD enzyme activity...

Neutropenia is a common dose-limiting toxicity associated with irinotecan treatment. Although UGT1A1 variants have been associated with neutropenia, a fraction of neutropenia risk remains unaccounted for. To identify additional genetic markers contributing to variability in irinotecan pharmacokinetics and neutropenia, a regression analysis was performed in 78 irinotecan-treated patients to analyze comprehensively three hepatic efflux transporter genes (ABCB1, ABCC1 and ABCG2). rs6498588 (ABCC1) and rs12720066 (ABCB1) were associated with increased SN-38 exposure, and rs17501331 (ABCC1) and rs12720066 were associated with lower absolute neutrophil count nadir...

Chronic liver disease is often associated with the infection by hepatitis C virus (HCV), which is an enveloped RNA virus belonging to the Flaviviridae family. Many studies found that milk proteins, such as lactoferrin, might have profound antiviral activity against HCV. Various secretory fluids ranging from milk, to tears, saliva, and nasal secretion, and to bile and pancreatic juice, as well as neutrophils, mucosal surfaces, and blood contain a widely spread multifunctional glycoprotein, lactoferrin (Lf), structure of which can be depicted as two homologous domains connected by the short spacer peptide...

In chronic hepatitis, pathologies reveal a prominent inflammatory infiltrate portal consisting mostly of lymphocytes and plasma cells invading the portal spaces, although one can also identify macrophages, neutrophils or eosinophils. In all the forms of chronic hepatitis, fibrosis starts in the portal area, namely periportally, subsequently extends towards the lobules to the central veins, causing septa, followed by fibrosis. We studied 52 patients with chronic hepatitis C, who underwent a hematological, biochemical, virological and histopathological investigation...

Pannexins constitute a relatively new family of transmembrane proteins that form channels linking the cytoplasmic compartment with the extracellular environment. The presence of pannexin1 in the liver has been documented previously, where it underlies inflammatory responses, such as those occurring upon ischemia-reperfusion injury. In the present study, we investigated whether pannexin1 plays a role in acute drug-induced liver toxicity. Hepatic expression of pannexin1 was characterized in a mouse model of acetaminophen-induced hepatotoxicity...

Carbon monoxide (CO) has attracted attention as a possible therapeutic agent for affecting anti-inflammatory and antioxidant activities. Previously, CO-bound hemoglobin vesicle (CO-HbV) was developed as a nanotechnology-based CO donor, and its safety profile and therapeutic potential as a clinically applicable carrier of CO were examined in vitro and in vivo. In the present study, the therapeutic efficacy of CO-HbV against severe acute pancreatitis was examined with secondary distal organ-injured model mice that were fed with a choline-deficient ethionine-supplemented diet...

Alcoholism is a multifactorial and complex disorder responsible for 5.9% of deaths worldwide. Excessive consumption of ethanol (Et-OH) induces alcoholic liver disease (ALD), a condition comprising a spectrum of clinical signs and morphological changes, ranging from fatty liver (steatosis) to more severe forms of chronic liver injury. Secondary cofactors, such as nutritional and hepatotoxic comorbid conditions, can also contribute to liver disease development. Here we investigated the effects in the progression of ALD following short-term exposure to diet high in refined carbohydrates (HC), a high-sugar and -butter (HSB) hypercaloric diet and acute Et-OH consumption...
