Salidroside [2-(4-hydroxyphenyl)ethyl β-D-gluco-pyranoside (SAS)] has been identified as the most potent ingredient of the plant Rhodiola rosea L. Previous studies have demonstrated that it possesses a number of pharmacological properties, including anti-aging, anti-fatigue, antioxidant, anticancer and anti-inflammatory properties. In this study, to ascertain the molecular mechanisms responsible for the anti-inflammatory activity of SAS, we used phorbol-12-myristate-13-acetate (PMA) plus A23187 to induce inflammation in human mast cell line-1 (HMC-1)...

Inflammatory bowel diseases (IBDs) are thought to develop as a result of complex interactions between host genetics, the immune system and the environment including the gut microbiome. Although an improved knowledge of the immunopathogenesis of IBDs has led to great advances in therapy such as the highly effective anti-tumor necrosis factor class of medications, a significant proportion of patients with Crohn's disease and ulcerative colitis do not respond to anti-tumor necrosis factor antibodies. Further understanding of the different immune pathways involved in the genesis of chronic intestinal inflammation is required to help find effective treatments for IBDs...

It has been reported previously that the density of angiotensin II receptors is increased in the rat liver in experimentally-induced fibrosis. We hypothesized that pharmacological blockade of angiotensin receptors may produce beneficial effects in models of liver fibrosis. In this study, we used the widely used thioacetamide (TAA)-induced model of liver fibrosis (300 mg/L TAA ad libitum for 12 weeks). Rats received daily injections (i.p), lasting 4 weeks of the angiotensin II type 1 receptor antagonists, losartan 30 mg/kg (TAA + L) or telmisartan 10 mg/kg (TAA + T) and were compared to rat that received TAA alone...

A certain nucleosomal protein-high mobility group box-1 (HMGB1)-has recently been established as a late mediator of sepsis, with a relatively wide therapeutic window for pharmacological intervention. Pelargonidin (PEL) is a well-known red pigment found in plants; it has important biological activities that are potentially beneficial for human health. In the present study, we investigated whether PEL can modulate HMGB1-mediated inflammatory responses in human umbilical vein endothelial cells (HUVECs) and in mice...

BACKGROUND: Tuberculosis (TB) causes a major burden on global health with long and cumbersome TB treatment regimens. Host-directed immune modulating therapies have been suggested as adjunctive treatment to TB antibiotics. Upregulated cyclooxygenase-2 (COX-2)-prostaglandin E2 (PGE2) signaling pathway may cause a dysfunctional immune response that favors survival and replication of Mycobacterium tuberculosis (Mtb). METHODS: Blood samples were obtained from patients with latent TB (n = 9) and active TB (n = 33) before initiation of anti-TB chemotherapy...

The pathway leading from amyloid-β deposition to cognitive impairment is believed to be a cornerstone of the pathogenesis of Alzheimer's disease (AD). However, what drives amyloid buildup in sporadic nongenetic cases of AD is still unknown. AD brains feature an inflammatory reaction around amyloid plaques, and a specific subset of the gut microbiota (GMB) may promote brain inflammation. We investigated the possible role of the GMB in AD pathogenesis by studying the association of brain amyloidosis with (1) GMB taxa with pro- and anti-inflammatory activity; and (2) peripheral inflammation in cognitively impaired patients...

Epigallocatechin-3-gallate (EGCG) has been shown to possess anti-inflammatory effects. Microcystin-LR (MC-LR) is a potent toxin and our past research suggested that it also mediated human umbilical vein endothelial cell (HUVEC) injury. The aim of this study was to investigate the effects of EGCG on MC-LR-induced oxidative stress and inflammatory responses in HUVECs. HUVECs were stimulated with MC-LR in the presence or absence of EGCG. MC-LR (40 μM) significantly increased cell death and decreased cell viability, migration, and tube formation, whereas EGCG (50 μM) inhibited these effects...

BACKGROUND/AIMS: Genipin is a component of Japanese traditional herbal medicine (Kampo), inchinkoto, and is used for the treatment of various liver injuries. However, there are few scientific evidence for its anti-inflammatory effects and mechanisms. In inflamed liver, proinflammatory cytokines including tumor necrosis factor (TNF)-α and interleukin (IL)-1β stimulate liver cells, followed by the expression of inducible nitric oxide synthase (iNOS). Excessive levels of NO produced by iNOS have been implicated as one of the factors in liver injury...

Psoriasis is a chronic systemic immune-mediated inflammatory dermatosis associated with several comorbidities. Psoriasis patients are at increased risk of developing cardiovascular diseases (CVD), namely, coronary heart disease, stroke or peripheral vascular disease, and psoriasis seems to be an independent cardiovascular risk factor. Antipsoriatic systemic therapy, especially anti-tumor necrosis factor (TNF)-α, seems to exert a beneficial effect on these comorbidities. The purpose of this study was: (i) to measure the level of cardiovascular serum markers in psoriasis patients in comparison with healthy volunteers; and (ii) to compare the serum level of the same markers in patients before and 3 months after adalimumab therapy...

Tumor necrosis factor (TNF) is a key cytokine in HIV replication and pathogenesis. For reasons that are not entirely clear, the cytokine remains upregulated despite anti-retroviral therapy (ART). Here we demonstrate that HIV Nef induces an alternative TNF secretion mechanism that remains active in chronic infection. Ingestion of Nef-containing plasma extracellular vesicles (pEV) from ART patients by primary immune cells, but also Nef expression, induced intracellular proTNF cleavage and secretion of vesicular TNF endosomes...

In vitro cell-based models are important tools for assessing efficacies of new leads in early phases of drug development. Human osteoarthritic chondrocytes (OACs), obtained from biomedical waste material, represent a valuable, relatively accessible cellular source that could be used for this purpose. By employing reverse transcription-polymerase chain reaction (qRT-PCR) we compared gene expression profiles of key anabolic, catabolic and inflammatory genes of freshly isolated vs. monolayer cultured OACs (passages P0-P2) and non-stimulated vs...
