REVIEW
E O Gubernatorova, A V Tumanov
Ulcerative colitis and Crohn's disease are the major forms of inflammatory bowel disease. Cytokines of the tumor necrosis factor (TNF) family play an important role in the regulation of intestinal inflammation. In this review, we discuss the function of key cytokines of this family - TNF and lymphotoxin (LT) - in mucosal healing, IgA production, and in control of innate lymphoid cells (ILCs), novel regulators of mucosal homeostasis in the gut. TNF plays a central role in the pathogenesis of inflammatory bowel diseases (IBD)...

Myeloid-derived suppressor cells represent a heterogeneous population of immature myeloid cells. Under normal conditions, these cells differentiate into macrophages, dendritic cells, and granulocytes. However, in pathological states such as inflammation, infection, or tumor growth, there is an arrest of their differentiation that results in the accumulation of immature myeloid cells in the organism. In addition, these cells acquire a suppressor phenotype, expressing anti-inflammatory cytokines and reactive oxygen and nitrogen species, and suppress T-cell immune response...

Oxidative stress induced by hemorrhagic shock (HS) initiates a systemic inflammatory response, which leads to subsequent kidney injury. This study assessed the efficacy of c-type natriuretic peptide (CNP) in attenuating kidney injury in a rat model of hemorrhagic shock and resuscitation (HS/R). Sodium pentobarbital-anesthetized adult male Wistar rats underwent HS induced by the withdrawal of blood to a mean arterial pressure of 30-35 mmHg for 50 min. Then, the animals received CNP (25 μg/kg) or vehicle (saline) intravenously, followed byresuscitation with 1...

Inflammation is associated with the development and malignant progression of most cancers. As most of the cell types involved in cancer-associated inflammation are genetically stable and thus are not subjected to rapid emergence of drug resistance, the targeting of inflammation represents an attractive strategy both for cancer prevention and for cancer therapy. Tumor-extrinsic inflammation is caused by many factors, including bacterial and viral infections, autoimmune diseases, obesity, tobacco smoking, asbestos exposure, and excessive alcohol consumption, all of which increase cancer risk and stimulate malignant progression...

In the cancer microenvironment, extracellular communication allows various types of cells to coordinate and execute biological functions. Emerging evidence indicates that exosomes, as mediators of cell communication, are involved in tumor progression. Little is known, however, about the mechanism by which exosomal miRNAs regulate inflammatory infiltration in arsenite-induced liver cancer. The present research aimed to determine if miRNAs secreted from arsenite-transformed human hepatic epithelial (L-02) cells are transferred into normal L-02 and THLE-3 cells, which are functionally active in the recipient cells...

Heparanase, the sole heparan sulfate degrading endoglycosidase, regulates multiple biological activities that enhance tumor growth, angiogenesis and metastasis. Heparanase expression is enhanced in almost all cancers examined including various carcinomas, sarcomas and hematological malignancies. Numerous clinical association studies have consistently demonstrated that upregulation of heparanase expression correlates with increased tumor size, tumor angiogenesis, enhanced metastasis and poor prognosis. In contrast, knockdown of heparanase or treatments of tumor-bearing mice with heparanase-inhibiting compounds, markedly attenuate tumor progression further underscoring the potential of anti-heparanase therapy for multiple types of cancer...

Gene expression profiling in Philadelphia-negative chronic myeloproliferative neoplasms (MPNs) have unraveled significant deregulation of several immune and inflammation genes of potential importance for clonal evolution. Other mechanisms might be downregulation of major histocompatibility class I and II genes used by tumor cells to escape antitumor T-cell-mediated immune responses. Several genes encoding human leukocyte antigen (HLA) class I and II molecules have been shown to be significantly downregulated...

In traditional Indian medicine, the plant Gmelina arborea Linn. (GA) is described to have the ability to relieve edema. The present study evaluates the anticancer property of GA stem bark against 7,12-dimethylbenz(a) anthracene (DMBA)-croton oil-induced skin tumorigenesis along with the evaluation of anti-inflammatory activity. The observed inhibition of inflammation in carrageenan-induced (41.8%) and formalin-induced (34.07%) models may be due to inhibition of prostaglandins (PGs). Skin papilloma was induced by a single topical application of DMBA (470 nmol/200 µL acetone), followed by repeated application of croton oil (1% in 200 µL acetone)...

Immune checkpoint blockaders (ICBs) act by unbalancing the immune system, thus favoring the development of an immune-mediated antitumor effect. ICBs targeting the programmed cell death receptor-1 (PD-1) have recently been investigated in a number of advanced tumors, including non-small cell lung cancer (NSCLC). Nivolumab, a fully human IgG4 kappa directed against PD-1, has been the first ICB to be approved for second-line treatment of advanced NSCLC. Areas covered: In this review we focus on the clinical development of nivolumab for the treatment of advanced NSCLC, with an emphasis on its safety profile...

It is widely acknowledged that a close relationship is between inflammation and colon cancer. Interleukin (IL)-17A and myeloid-derived suppressor cells (MDSCs) play an important role in the development of colitis-associated cancer (CAC). However, the precise changes of IL-17, MDSCs, and Th17 cells during the CAC progression have not been observed in the colorectal chronic inflammation-dependent tumor. In this study, we found the level of IL-17 was increased in pathogenic colon site during the early stage of CAC model...

Endometrial cancer is the sixth most common cancer in women worldwide and the most common gynecologic malignancy in the developed world. This chapter explores the current epidemiologic evidence on the association between obesity and endometrial cancer risk and mortality. Using body mass index (BMI) as a measure of obesity, we found that obesity (defined as BMI > 30 and < 35 kg/m(2)) was associated with a 2.6-fold increase in endometrial cancer risk, while severe obesity (BMI > 35 kg/m(2)) was associated with a 4...

L-theanine, a water-soluble amino acid isolated from green tea (Camellia sinensis), has anti-inflammatory activity, antioxidative properties, and hepatoprotective effects. However, the anti-allergic effect of L-theanine and its underlying molecular mechanisms have not been elucidated. In this study, we investigated the protective effects of L-theanine on asthmatic responses, particularly airway inflammation and oxidative stress modulation in an ovalbumin (OVA)-induced murine model of asthma. Treatment with L-theanine dramatically attenuated the extensive trafficking of inflammatory cells into bronchoalveolar lavage fluid (BALF)...
