Abstract
Endothelial cell apoptosis driven by inflammation (TNF-α) plays a critical role in the pathogenesis of atherosclerosis, but the exact molecular mechanisms are not clearly elucidated. MicroRNA (miR)-29 families (a/b/c) take important roles in pathophysiological processes of atherosclerosis, also the underlying mechanisms have not been fully clarified. The aims are to explore whether or not miR-29 families mediate the apoptotic effects of TNF-α on endothelial cells and uncover the underlying molecular mechanisms. In this study, MTT assay and flow cytometer analysis were employed respectively to determine the proliferation and apoptosis of human umbilical vascular endothelial cells (HUVECs) under TNF-α exposure. Real-time quantitative PCR and western blot were performed to detect the levels of target RNAs and proteins/their phosphorylation in HUVECs. TNF-α could inhibit HUVEC proliferation and induce HUVEC apoptosis in a positive dose- and time-dependent manner, with a similar way of miR-29a upregulation, but no effects on miR-29b/c. Upregulation of miR-29a with its mimics enhanced the apoptotic effect of TNF-α on HUVECs, but downregulation of miR-29a using anti-miR-29a blocked up its apoptotic effect. MiR-29a inhibited the expression of PI3Kp85α and Bcl-2 and blocked up the signal transduction of PI3K/AKT/Bcl-2 axis to mediate the apoptotic effect of TNF-α on HUVECs. Mediating the inflammation-driven endothelial cell apoptosis is an important biology mechanism by which miR-29a promotes atherosclerosis and its complications. MiR-29a will be a potential diagnostic and therapeutic target for atherosclerotic cardiovascular diseases; it is worthwhile to further study.

Abstract
Autoimmune hemolytic anemia (AIHA) is due to autoantibodies with or without complement activation and involves cellular and cytokine dysregulation. Here, we investigated cytokine single-nucleotide polymorphisms (SNPs) of TNF-α, TGF-β1, IL-10, IL-6, and IFN-γ, along with their serum levels. The former were related to hematological parameters, therapy, and clinical outcome. The study included 123 consecutive patients with primary AIHA [77 warm AIHA and 46 cold agglutinin disease (CAD)], followed up for a median of 49 months. Results show that the allelic frequency of TNF-α -308 G/A polymorphisms was significantly lower in patients versus controls. Moreover, the genotypic frequency of TNF-α -308G/A and TGF-β gene codon 25 G/C genotypes was significantly lower in patients versus controls. Considering cytokine SNP genotypes associated with different gene expression levels, TNF-α high gene expression was significantly more frequent in patients, TGF-β and IL-10 high gene expression was higher in patients with more severe anemia, and TGF-β high gene expression was higher in patients with active disease. Considering treatment, TNF-α and TGF-β high gene expression was more frequent in multitreated patients and particularly in CAD. It may be speculated that this genetic predisposition to a stronger inflammatory response may result in a greater immune dysregulation and in a relapsed/refractory disease. Regarding cytokine serum levels, TNF-α and TGF-β were significantly lower, and IL-10 and IL-6 were significantly higher in patients versus controls, underlying the complex interplay between genetic background and disease features.

Abstract
BACKGROUND Mesenchymal stem cells (MSCs) have been investigated as therapeutic agents for inflammatory bowel disease (IBD). Stimulation of MSCs with pro-inflammatory cytokines is an approach to enhance their immunomodulatory effects. However, further investigation is required to support their application in immune-mediated disorders and companion animals. OBJECTIVES This study aimed to assess the therapeutic effect of tumor necrosis factor (TNF)-α-stimulated feline adipose tissue-derived MSCs (fAT-MSCs) in a dextran sulfate sodium (DSS)-induced colitis mouse model. METHODS Colitis mice was made by drinking water with 3% DSS and fAT-MSCs were injected intraperitoneally. Colons were collected on day 10. The severity of the disease was evaluated and compared. Raw 264.7 cells were cultured with the conditioned medium to determine the mechanism, using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay. RESULTS TNF-α-stimulated fAT-MSCs more improved severity of DSS-induced colitis in disease activity, colon length, histologic score, and inflammatory cytokine. In sectionized colon tissues, the group comprising TNF-α-stimulated fAT-MSCs had higher proportion of CD11b+CD206+ macrophages than in the other groups. In vitro, TNF-α-stimulation increased cyclooxygenase-2 (COX-2) expression and prostaglandin E2 (PGE2) secretion from fAT-MSCs. The conditioned medium from TNF-α-stimulated fAT-MSCs enhanced the expression of interleukin-10 and arginase-1 in LPS-activated Raw 264.7 cells. CONCLUSIONS These results represent that TNF-α-stimulated fat-mscs ameliorate the inflamed colon more effectively. Furthermore, we demonstrated that the effectiveness was interlinked with the COX-2/PGE2 pathway.

Abstract
Diabetes mellitus (DM), a metabolic disorder characterized by insulin-deficiency or insulin-resistant conditions. The foremost microvascular complication of diabetes is diabetic retinopathy (DR). This is a multifaceted ailment mainly caused by the enduring adverse effects of hyperglycaemia. Inflammation, oxidative stress, and advanced glycation products (AGES) are part and parcel of DR pathogenesis. In regulating many cellular and biological processes, the family of fork-head transcription factors plays a key role. The current review highlights that FOXO is a requisite regulator of pathways intricate in diabetic retinopathy on account of its effect on microvascular cells inflammatory and apoptotic gene expression, and FOXO also has the foremost province in regulating cell cycle, proliferation, apoptosis, and metabolism. Blockage of insulin turns into an exaggerated level of glucose in the bloodstream and can upshot into the exaggerated triggering of FOXO1, which can ultimately uplift the production of several factors of apoptosis and inflammation, such as TNF-α, NF-kB, and various others, as well as reactive oxygen species, which can also come up with diabetic retinopathy. The current review also focuses on various therapies which can be used in the future, like SIRT1 signalling, resveratrol, retinal VEGF, etc., which can be used to suppress FOXO over activation and can prevent the progression of diabetic complications viz. diabetic retinopathy.

Abstract
Atopic dermatitis (AD) is characterized by progressive skin inflammation. In addition, sulforaphane is an isothiocyanate organosulfur compound from cruciferous vegetables. Sulforaphane was reported to ameliorate inflammatory responses. Therefore, this study was conducted to evaluate the protective effects of sulforaphane in AD through affecting the balance between pro-inflammatory and anti-inflammatory cytokines and to evaluate its effect on AD-induced activation of the apoptotic pathway. The method of repeated rubbing of 2,4-dinitrochlorobenzene (DNCB) on shaved dorsal skin and ears of mice was used for induction of AD. After the development of AD, part of the mice was injected with 1 mg/kg sulforaphane, subcutaneously three times weekly. Samples of skin were isolated for assessment of gene and protein expression of 8-hydroxy2'-deoxyguanosine, IgE, NFκB, TNF-α, IL-1β, IL-4, IL-10, Nrf2, and caspase-3. In addition, skin sections from different groups were stained with anti-caspase-3 antibodies. Mice in the AD group were characterized by increased gene and protein expression of 8-hydroxy2'-deoxyguanosine, IgE, NFκB, TNF-α, IL-1β, and caspase-3 associated with reduced expression of Nrf2, IL-4, and IL-10. Treatment of AD mice with sulforaphane significantly reduced the number of scratches, dermatitis score, and ear thickness. In addition, sulforaphane significantly attenuated the gene and protein expressions produced by AD. Therefore, sulforaphane alleviated AD induced in mice through inhibition of oxidative stress, oxidative DNA damage, inflammation, and apoptosis. HIGHLIGHTSAtopic dermatitis is a chronic relapsing inflammatory disease.Sulforaphane is an isothiocyanate organosulfur compound obtained from cruciferous vegetables.Sulforaphane alleviated AD induced in mice.Sulforaphane inhibits oxidative stress, oxidative DNA damage, inflammation, and apoptosis.

Abstract
OBJECTIVES To evaluate the effects of modafinil on neuropathic pain induced by sciatic nerve cuffing in mice, and possible contribution of nitrergic/inflammatory and serotonergic systems. METHODS Neuropathic pain was induced by applying a polyethylene cuff around the left sciatic nerve. Seven days later, mice received modafinil (50, 100, and 200 mg/kg; intraperitoneal [i.p.]) and morphine (10 mg/kg, i.p.) as control. Mice also received pretreatments of the nonselective nitric oxide (NO) synthase (NOS) inhibitor L-NAME, the selective neuronal NOS inhibitor 7-nitroindazole, the selective inducible NOS inhibitor aminoguanidine, and the selective serotonin reuptake inhibitor citalopram before modafinil (100 mg/kg). von Frey test was used to evaluate mechanical allodynia. Additionally, sciatic nerves were collected for histopathological analysis. Tissue levels of NO metabolites, tumor necrosis factor (TNF)-α, and interleukin (IL)-6 were assessed. RESULTS Animals whose sciatic nerves were cuffed had a significantly (P<0.001) decreased paw withdrawal threshold (PWT) compared with the sham-operated group. Modafinil (100 mg/kg) and morphine significantly reversed PWT (P<0.001). Pretreatments with L-NAME, 7-nitroindazole, aminoguanidine, and citalopram in different groups markedly reversed analgesic effects of modafinil. Tissue homogenates of Cuffed sciatic nerves showed significantly higher levels of NO metabolites, TNF-α and IL-6 (P<0.001). Modafinil lowered NO metabolites, TNF-α, and IL-6 levels (P<0.001). Histopathology illustrated marked axonal degeneration and shrinkage in the cuffed sciatic nerve, which were improved in the modafinil-treated group. CONCLUSIONS Modafinil exerts analgesic and neuroprotective effects in cuff-induced neuropathic mice via possible involvement of the nitrergic/inflammatory and serotonergic systems.

Abstract
This study examined the effect of N-acetyl cysteine (NAC), a reactive oxygen species (ROS) inhibitor, on renal interstitial fibrosis induced by unilateral ureteral obstruction (UUO) in mice. UUO led to a significant increase in the fibrotic area of obstructed kidneys, which was attenuated by NAC (84.8 mg/kg/d) in the drinking water. Renal expression of type III collagen and tumor necrosis factor (TNF)-α mRNAs was elevated in UUO mice and inhibited by NAC. Extracellular signal-regulated kinase (ERK1/2) phosphorylation was significantly elevated by UUO, and NAC significantly attenuated the elevation. UUO inhibited the activity of glutathione peroxidase, while NAC restored its activity. Together, the results of this study suggest that renal interstitial fibrosis induced by UUO was ameliorated by NAC via several mechanisms including increased glutathione peroxidase activity, reduced phosphorylation of ERK1/2, and reduced expression of TNF-α and type III collagen mRNAs.

Abstract
Objectives: Hepatocellular carcinoma (HCC) is characterized by elevated in oxidative stress and inflammatory cytokines, which enhance destructive effects of the tumor. Therefore, we conducted this study to investigate the protective effects of sodium ascorbate against thioacetamide-induced HCC in rats through studying its effect on the apoptotic pathway in rats. In addition, in vitro activity of sodium ascorbate was investigated on HepG2 and compared with cisplatin. Methods: HCC was experimentally induced by injecting rats with 200 mg/kg thioacetamide intraperitoneally twice weekly for 16 weeks. Part of HCC rats was concomitantly treated with 100 mg/kg sodium ascorbate intraperitoneally during the 16-week period. Hepatic tissues were used for the determination of NFκB, Nrf2, TNF-α, caspase-3, caspase-8 and caspase-9. Results: Sodium ascorbate significantly attenuated HCC-induced reduction in the expression of NrF2 associated with a reduction in concentrations of hydrogen peroxide and superoxide anion. In addition, sodium ascorbate blocked HCC-induced increase in the expression of NFκB and TNF-α. Sodium ascorbate slightly increased the activity of caspase-3, -8 and -9 in vitro but inhibited their activities in vivo. Conclusion: In spite of the antioxidant and anti-inflammatory activity of sodium ascorbate, it produced selective cytotoxic activity via direct activation of the apoptotic pathway in cancer cells without affecting the apoptotic pathway in normal hepatic cells.

Abstract
Inflammatory bowel disease, which typically manifests as Crohn's disease and ulcerative colitis, is caused by the abnormal production of cytokines such as tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β. These cytokines damage intestinal epithelial cells and trigger fibrosis, respectively, for which the current in vitro models have many limitations. Therefore, we tested whether human induced pluripotent stem cell-derived intestinal organoids (HiOs) can mimic inflammatory bowel disease (IBD), and whether such a model is suitable for drug screening. HiOs were treated with TNF-α and TGF-β to construct mucosal damage and fibrosis models. TNF-α diminished the mRNA expression of intestinal epithelial cell and goblet cell markers in HiOs. TNF-α also induced epithelial cell damage and degradation of tight junctions but not in the presence of infliximab, an antibody used in the clinic to deplete TNF-α. Furthermore, permeation of the non-absorbable marker FD-4 was observed in HiOs treated with TNF-α or ethylene glycol tetraacetic acid (EGTA), but not in the presence of infliximab. In contrast, TNF-α and TGF-β induced mRNA expression of mesenchymal and fibrosis markers, as well as epithelial-mesenchymal transition. SB431542, a TGF-β inhibitor, significantly reversed these events. The data indicate that HiOs mimic mucosal damage and fibrosis due to IBD and are thus suitable models for drug screening.

Abstract
Cancer cachexia (CC), characterized by body weight loss and sarcopenia, contributes to over 20% of all cancer-related death. Approximately 80% of pancreatic cancer (PC) patients develop CC during disease progression. Pro-inflammatory cytokines, including interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor (TNF)-α, have been correlated with CC; however, its prognostic significance remains unclear. In this study, serum levels of the CC-related cytokines were determined in normal donors and PC patients. IL-8 expression was assessed in PC tissue microarrays. The correlation of levels of each cytokine with disease progression, weight loss, and sarcopenia was calculated. The relationships among the baseline variables, CC, and IL-8 expression with disease progression were examined using univariate and multivariate analyses. Of these mentioned cytokines, only serum IL-8 level was elevated in the locally advanced group (n = 55) compared with the normal (n = 17) and resected groups (n = 55). Serum IL-8 level was positively correlated with CC status, weight loss, sarcopenia, but was negatively correlated with total psoas area (TPA). IL-8 expression in tissue samples was also positively associated with weight loss. Furthermore, serum IL-8 level was an independent predictor of survival. In conclusion, elevated serum IL-8 level significantly correlates with CC and sarcopenia and can be used as a prognostic indicator in PC.

Abstract
The brain has high-order functions and is composed of several kinds of cells, such as neurons and glial cells. It is becoming clear that many kinds of neurodegenerative diseases are more-or-less influenced by astrocytes, which are a type of glial cell. Aquaporin-4 (AQP4), a membrane-bound protein that regulates water permeability is a member of the aquaporin family of water channel proteins that is expressed in the endfeet of astrocytes in the central nervous system (CNS). Recently, AQP4 has been shown to function, not only as a water channel protein, but also as an adhesion molecule that is involved in cell migration and neuroexcitation, synaptic plasticity, and learning/memory through mechanisms involved in long-term potentiation or long-term depression. The most extensively examined role of AQP4 is its ability to act as a neuroimmunological inducer. Previously, we showed that AQP4 plays an important role in neuroimmunological functions in injured mouse brain in concert with the proinflammatory inducer osteopontin (OPN). The aim of this review is to summarize the functional implication of AQP4, focusing especially on its neuroimmunological roles. This review is a good opportunity to compile recent knowledge and could contribute to the therapeutic treatment of autoimmune diseases through strategies targeting AQP4. Finally, the author would like to hypothesize on AQP4’s role in interaction between reactive astrocytes and reactive microglial cells, which might occur in neurodegenerative diseases. Furthermore, a therapeutic strategy for AQP4-related neurodegenerative diseases is proposed.

Abstract
Omega-3, a polyunsaturated fatty acid, is an essential fatty acid necessary for human health, and it protects against cardiovascular disease, inflammation, autoimmune diseases, and cancer. In the present study, we investigated the effects of omega-3-rich harp seal oil (HSO) on the production of nitric oxide (NO) and cytokines, such as tumor necrosis factor (TNF)-α, interleukin-(IL)-1β, IL-6, and IL-12/IL-23 (p40) in peritoneal macrophages of mice. The culture supernatants of murine macrophages exposed to lipopolysaccharide (LPS), HSO, or HSO+LPS were harvested to assay IL-1β, TNF-α, IL-6, and IL-12/IL-23 (p40) cytokines and NO. TNF-α, IL-1 β, and IL-12/IL-23 (p40) levels, except IL-6, were lower in the culture supernatants of mouse peritoneal macrophages exposed to LPS plus HSO than those of the groups exposed to LPS alone. These observations demonstrate that omega-3-rich harp seal oil downregulates the production of the pro-inflammatory cytokines such as IL-1β, TNF-α, and IL-12/IL-23 (p40). These results suggest that HSO could be potentially used as a preventive agent or as an adjunct in anti-inflammatory therapy, if more research results were accumulated.

Abstract
Background Inflammatory bowel disease is an immunologically mediated disease. Notably, it is less common in countries where there is a greater risk of exposure to helminths. In our study, we examined the modulatory effect of the laminated layer extracted from the cyst wall of a helminth parasite, Echinococcus granulosus, on dextran sulfate sodium (DSS)-induced colitis in mice. Methods An acute colitis was induced in BALB/c mice using 2.5% w/v DSS in drinking water. The crude extract of E. granulosus laminated layer was injected intraperitoneally daily, starting 3 days before colitis induction. The Disease Activity Index was monitored daily, colon length and weight were measured and histological scores were evaluated. Nitric oxide (NO) and cytokine levels (interferon γ (IFN-γ), tumor necrosis factor α (TNF-α) and interleukin 10 (IL-10)) were assessed by enzyme-linked immunosorbent assay. In addition, the colonic expression of inducible nitric oxide synthase (iNOS) and nuclear factor-κB (NF-κB) was examined. Statistical analyses were performed by one-way analysis of variance and the survival rate was analyzed by the long rank test. Results Hydatid laminated layer pretreatment significantly improved the clinical symptoms and histological scores (*** p < 0.01) observed during DSS-induced colitis and maintained mucus production by goblet cells. Furthermore, treatment with hydatid laminated layer caused a significant decrease in NO, IFN-γ (** p < 0.01) and TNF-α production (* p < 0.05) and an increase in IL-10 production. These results were associated with localized downregulation of iNOS and NF-κB expression. Conclusions Our results demonstrate the potent anti-inflammatory effects of hydatid laminated layer. Furthermore, preventive treatment with the laminated layer played a beneficial role in maintaining the integrity of the intestinal mucosal barrier against DSS-induced injury.

Abstract
OBJECTIVES The serotonin hypothesis plays a critical role in the etiology of bipolar disorder (BD). Although many studies have demonstrated reciprocal relationships between serotonin metabolism and immune-inflammatory pathways that occur in depression, studies linking serotonergic function and cytokines are still limited concerning BD. The aim of this study was to investigate the interaction of brain serotonin transporter (SERT) and cytokines in BD. METHODS Twenty patients with euthymic BD and 20 age- and sex-matched healthy controls (HC) were recruited. Single photon emission computed tomography with the radiotracer (123) I-ADAM was used for the SERT imaging. The specific uptake ratio, which represents SERT availability, was the primary measured outcome. Cytokines included the pro-inflammatory cytokine tumor necrosis factor-α (TNF-α) and the anti-inflammatory cytokine interleukin-10 (IL-10). Cytokine concentration was measured using an enzyme-linked immunosorbent assay. RESULTS SERT availability was significantly lower in the midbrain and caudate of patients with BD compared with HC, but not in the thalamus and putamen. IL-10 was significantly higher, whereas TNF-α was not different in euthymic patients with BD compared with HC. There was a significant association of SERT availability and IL-10 in the thalamus, but not in the midbrain, caudate, or putamen. CONCLUSIONS Our results demonstrate the interaction of SERT availability and IL-10 in euthymic BD. This result may further explain the role of SERT and cytokines in the etiology of BD.
