Anti-tumour necrosis factor (TNF) agents have demonstrated efficacy in inflammatory bowel disease (IBD). Cutaneous reactions such as new onset psoriasis or psoriasiform-like reactions are among the most common adverse reactions. We retrospectively identified cases of anti-TNF-induced psoriasis or psoriasiform manifestations in IBD patients at a tertiary centre in Australia. A total of 10 (six females) of 270 (3.7%) IBD patients treated with anti-TNF therapy developed drug-induced psoriatic or psoriasiform-like reactions: five patients were treated with infliximab and five with adalimumab; nine had Crohn disease...

In folklore medicine, the plant Emilia sonchifolia, belonging to the family Asteraceae, is used for treating tumour and inflammation. In our previous studies, we have done a thorough phytochemical investigation of E. sonchifolia with a report on its potent antimetastatic activity. Further, we isolated and characterised its active fraction (AFES) containing the major compound γ-humulene with an evaluation of the antiangiogenic effect of AFES (5 mg/kg b.wt.). In the first part of the present study, AFES in different concentrations was used for the assessment of its possible anti-inflammatory effect employing three in vivo inflammatory models...

BACKGROUND/AIMS: Regulatory T cells (Tregs) can suppress immunologic damage in myocardial ischaemia/reperfusion injury (MIRI), however, the isolation and ex vivo expansion of these cells for clinical application remains challenging. Here, we investigated whether the IL-2/anti-IL-2 complex (IL-2C), a mediator of Treg expansion, can attenuate MIRI in mice. METHODS: Myocardial I/R was surgically induced in male C57BL/6 mice, aged 8-10 weeks, that were randomly assigned to 1) sham group (Sham), 2) Phosphate Buffered Saline (PBS), 3) IL-2-anti-IL-2 Ab complex (IL-2C), or 4) sham group, 5) PBS, 6) IL-2C after MIRI, or 7) IL-2C, 8) IL-2C+anti-CD25 mAbs, or 9) IL-2C; 10) IL-2C+anti-TGF-β1 mAbs, 11) IL-2C+anti-IL-10 mAbs...

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery is associated with increased short- and long-term mortality. Inflammation, oxidative stress, and endothelial dysfunction and damage play important roles in the development of AKI. High-density lipoproteins (HDLs) have anti-inflammatory and antioxidant properties and improve endothelial function and repair. Statins enhance HDL's anti-inflammatory and antioxidant capacities. We hypothesized that a higher preoperative HDL cholesterol concentration is associated with decreased AKI after cardiac surgery and that perioperative statin exposure potentiates this association...

The overpopulation of free-roaming companion animals has become the global crisis. The development and application of a suitable, effective, non-surgical approach for animal sterilization would have an enormous advantage over the current surgical method. The main purpose of this study was to develop and evaluate a novel nanomedicine-based chemosterilant for non-surgical castration of male companion animals. In this study, we first sought to investigate the testicular toxicity of different apoptosis-inducing agents...

Alzheimer's disease (AD) is marked by several cellular and molecular damage. Therefore, the therapeutic interest of multi-target molecules is increasingly justified. Polyphenols presenting multiple pharmacological effects would be more efficient. In this study, beneficial effects of trans ε-viniferin, a natural polyphenol were thus evaluated. This study reported that this stilbenoid (1) induced the disaggregation of amyloid β (Aβ) peptide and (2) rescued inflammation in murine primary neuronal cultures. These both effects are higher than those of resveratrol, and so, trans ε-viniferin could be a good therapeutic multi-target candidate...

Atherosclerosis accounts for numerous cardiovascular diseases, and cytokines have a critical role in acceleration or suppression of disease. Salusin-α presents a new class of bioactive peptides that can have anti-atherogenic properties. Therefore, the effects of salusin-α on the expression of some pro- and anti-inflammatory cytokines and on TNF-α-induced inflammatory responses in human umbilical vein endothelial cells (HUVECs) were examined. The involvement of the NF-κB pathway in effects of salusin-α in HUVECs was checked using Bay 11-7082 as an NF-κB inhibitor...

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...

Inflammation and oxidative stress are common in many chronic diseases. Targeting signaling pathways that contribute to these conditions may have therapeutic potential. The transcription factor Nrf2 is a major regulator of phase II detoxification and anti-oxidant genes as well as anti-inflammatory and neuroprotective genes. Nrf2 is widespread in the CNS and is recognized as an important regulator of brain inflammation. The natural product curcumin exhibits numerous biological activities including ability to induce the expression of Nrf2-dependent phase II and anti-oxidant enzymes...

Inflammatory mechanisms, involving granulocytes, T-cells, B-cells, macrophages and activated microglia, have been suggested to play a pathogenic role in experimental models of stroke and may be targets for therapeutic intervention. However, knowledge on the inflammatory response in human stroke lesions is limited. Here, we performed a quantitative study on the inflammatory reaction in human ischemic infarct lesions. We found increased numbers of T-lymphocytes, mainly CD8+ cells, but not of B-lymphocytes. Their number was very low in comparison to that seen in inflammatory diseases of the central nervous system and they did not show signs of activation...

Increasing evidence suggests that neurodegeneration occurs in part because the environment is affected during disease in a cascade of processes collectively termed neuroinflammation. This is a reactive response of the central nervous system against noxious elements that interfere with tissue homeostasis. Neuroinflammation is mediated by inflammatory molecules released by microglial cells. Understanding and controlling interactions between the immune system and microglial activation might represent the key to prevent or delay the onset of central nervous system diseases...

Nonsteroidal anti-inflammatory drugs (NSAIDs)-induced small intestinal injury (enteropathy) occurs in about two-thirds of regular NSAID users. To date, there is no proven-effective treatment for NSAID enteropathy, and its underlying mechanism remains obscure. The present study showed that glucocorticoids are an important determinant of NSAID enteropathy. High dose dexamethasone (DEX, 75 mg/kg) markedly exacerbated the acute toxicity of ibuprofen (IBU, 200 mg/kg) in the small intestine of mice, which was not due to the pregnane-X-receptor pathway...
