INTRODUCTION: A link of psoriasis with subclinical atherosclerosis has been postulated and cytokine network might intermediate this association. Few data are available in patients with mild psoriasis. We evaluated carotid intima-media thickness (cIMT) in drug-free psoriatic individuals and controls. In parallel, we searched for associations of cIMT with disease activity indexes and serum interleukins (IL) in psoriatic patients. METHOD: An experienced radiologist performed the cIMT analyses...

Previous research indicates there may be an association between inflammation and depression in older adults but results are inconsistent. Therefore, the aim of this review was to determine the cross-sectional and longitudinal associations of two inflammatory markers C-reactive protein (CRP) and Interleukin-6 (IL-6) with depression in older adults. We searched five databases for cross-sectional and longitudinal studies reporting an association between CRP or IL-6 with depression among adults sampled from the community aged 50 or older...

Short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate, play an important role in the maintenance of intestinal homeostasis. In the present study, anti-inflammatory effects of SCFAs were examined in human intestinal Caco-2 cells and mouse colonic cultures. Stimulation of Caco-2 cells with tumor necrosis factor (TNF)-α induced interleukin (IL)-8 (TNF-α, 17.1 ± 7.2 vs Control, 1.00 ± 0.26, P<0.01) and IL-6 expression (TNF-α, 21.7 ± 10.0 vs Control, 1.00 ± 0.28, P<0.01) through the activation of nuclear factor κB p65, spleen tyrosine kinase, and mitogen-activated protein kinase pathways...

Indirubins are natural occurring alkaloids extracted from indigo dye-containing plants. Indirubins could inhibit various kinases, and might be used to treat chronic myelocytic leukemia, cancer and neurodegenerative disorders. 7-bromoindirubin-3-oxime (7Bio), an indirubin derivative derived from indirubin-3-oxime, possesses inhibitory effects against cyclin-dependent kinase-5 (CDK5) and glycogen synthase kinase-3β (GSK3β), two pharmacological targets of Alzheimer's disease (AD). In this study, we have discovered that 2...

Skin cancer represents a serious public health problem and melanoma is considered the most significant due to its high metastasis capacity. Evasion mechanisms are the main characteristic of these tumor cells to escape of immune response. Extracellular nucleotides and nucleosides play an important role in inflammatory and immune responses. In this study, we analyzed the expression and activity of purinergic system enzymes in platelets and lymphocytes, ATP levels quantification, as well the level of pro and anti-inflammatory interleukins in the serum of 23 patients with surgical melanoma removal (CM group) and 23 control subjects (CT group)...

The pathogenesis of psoriasis can be explained by dysregulation of immunological cell function as well as keratinocyte proliferation/differentiation. Recently, the immunological pathomechanism has been clarified substantially. Whereas T-helper (Th)1 overactivation was thought to induce occurrence of psoriasis, it has been demonstrated that Th17 cells play a key role. Th17 development is maintained by interleukin (IL)-23 mainly produced by dendritic cells. Th17 cells produce various cytokines, including IL-17A, IL-17F and IL-22...

Increased understanding of the immunopathology of inflammatory bowel disease (IBD) has led to the development of targeted therapies and has unlocked a new era in IBD treatment. The development of treatment options aimed at a variety of pathological mechanisms offers new hope for customized therapies. Beyond anti-tumor necrosis factor agents, selective lymphocyte trafficking inhibitors have been proposed as potent drugs for IBD. Among these, vedolizumab has recently been approved for both Crohn's disease and ulcerative colitis...

Two new nardosinone-type sesquiterpenoids, namely kanshone J (1) and kanshone K (2) along with seven known terpenoids (3-9) were isolated from the rhizomes and roots of Nardostachys jatamansi DC (Valerianaceae). The structures of these compounds were determined mainly by analysis of 1D-, 2D-NMR and MS data. In addition, the absolute configuration of compound 1 was assigned by application of the modified Mosher's method. In an initial assay to evaluate their anti-neuroinflammatory effects, compounds 1-5 and 9 exhibited dose-dependent inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in BV2 cells, with IC50 values ranging from 2...

Psoriasis is largely mediated by interleukin (IL)-23/ T helper (Th) 17 axis, and IL-21 is a pleiotropic cytokine expressed by Th17 cells. Despite previously reported possible pathogenic roles of IL-21 in human psoriasis, we found that IL-21 receptor (IL-21R) signaling was not crucial for imiquimod-induced psoriatic inflammation, using IL-21R-/- mice. The severity of imiquimod-induced psoriatic manifestation and pro-inflammatory Th17 cytokine levels, IL-17A-producing γδ T cells and CD4+ T cells, and in vitro IL-17A production by γδ T cells after IL-23 stimulation was comparable between wild-type and IL-21R-/- mice...

Introduction: Ustekinumab, a monoclonal antibody targeting interleukins-12 and -23 is used to treat adults with Crohn's disease (CD). We determined the 30-day postoperative infectious complication rate among CD patients who received ustekinumab within 12 weeks prior to an abdominal operation as compared to patients who received anti-tumor necrosis factor (TNF) agents. Methods: A retrospective chart review of adults with CD who underwent an abdominal operation between 1/1/2015 and 5/1/2017 was performed across six sites...

BACKGROUND AND PURPOSE: Inflammatory mechanisms can exacerbate ischemic tissue damage and worsen clinical outcome in patients with stroke. Both αβ and γδ T cells are established mediators of tissue damage in stroke, and the role of dendritic cells (DCs) in inducing the early events of T cell activation and differentiation in stroke is not well understood. METHODS: In a murine model of experimental stroke, we defined the immune phenotype of infiltrating DC subsets based on flow cytometry of surface markers, the expression of ontogenetic markers, and cytokine levels...

Tuberculosis (TB) is characterised by extensive pulmonary matrix breakdown. Interleukin-17 (IL-17) is key in host defence in TB but its role in TB-driven tissue damage is unknown. We investigated the hypothesis that respiratory stromal cell matrix metalloproteinase (MMP) production in TB is regulated by T helper-17 (TH -17) cytokines. Biopsies of patients with pulmonary TB were analysed by immunohistochemistry (IHC) and patient bronchoalveolar lavage fluid (BALF) MMP and cytokine concentrations measured by Luminex assays...

Background: Ventilator-induced lung injury is considered to be a main factor in the pathogenesis of bronchopulmonary dysplasia (BPD). Optimizing ventilator strategies may reduce respiratory morbidities in preterm infants. Permissive hypercapnia has been suggested to attenuate lung injury. We aimed to determine if a higher PCO2 target range results in less lung injury compared to the control target range and possibly reduces pro-inflammatory cytokines and acid sphingomyelinase (ASM) in tracheal aspirates (TA), which has not been addressed before...

Inflammation is a critical phase in the healing of skin wounds. Excessive inflammation and inflammatory macrophages are known to cause impaired wound closure and outcome. This prompted us to test the role of IL-23 in IL-17 expression and in modulating wound inflammation and macrophage polarization. Full-thickness wounds (4 × 6 mm) were created on the dorsal surface of multiple genetically modified mouse models. Obese diabetic mouse wounds were treated with anti-IL-17A, anti-IL-23, or isotype-matched antibodies...

BACKGROUND: Obesity is associated with poorly differentiated and advanced prostate cancer and increased mortality. In preclinical models, caloric restriction delays prostate cancer progression and prolongs survival. We sought to determine if weight loss (WL) in men with prostate cancer prior to radical prostatectomy affects tumor apoptosis and proliferation, and if WL effects other metabolic biomarkers. METHODS: In this Phase II prospective trial, overweight and obese men scheduled for radical prostatectomy were randomized to a 5-8 week WL program consisting of standard structured energy-restricted meal plans (1200-1500 Kcal/day) and physical activity or to a control group...
