Agathisflavone is a bioactive compound in Anacardium occidentale. In this study, we investigated inhibition neuroinflammation in BV2 microglia by agathisflavone. Neuroprotective activity of the compound was investigated in differentiated SH-SY5Y cells. Experiments in lipopolysaccharide (LPS)-activated BV2 microglia showed that pretreatment with agathisflavone (5-20 μM) produced significant reduction in the release of tumour necrosis factor-α, interleukin-6, interleukin-1β, NO, and PGE2 from the cells. Immunoblotting experiments also revealed that agathisflavone reduced levels of iNOS and COX-2 protein...

REVIEW
Young-Su Yi
Inflammation is an innate immune response to noxious stimuli to protect the body from pathogens and dangers. Inflammatory responses consist of two main steps: priming and triggering. In priming, inflammatory cells increase expressions of inflammatory molecules, while in triggering, inflammasomes are activated, resulting in cell death and pro-inflammatory cytokine secretion. Inflammasomes are protein complexes comprising intracellular pattern recognition receptors (PRRs) (e.g. nucleotide-binding oligomerization domain-like receptors (NLRs), absent in melanoma 2 (AIM2), and caspases-4/5/11) and pro-caspase-1 with or without a bipartite adaptor molecule ASC...

An elemental diet (ED) has been reported to reduce oral mucositis and dermatitis induced by chemotherapy. However, its molecular mechanism of action as an anti‑inflammatory agent is still unknown. The aim of the present study was to clarify whether ED confers its anti‑inflammatory action via reduction of pro‑inflammatory cytokine production in keratinocytes in vivo and in vitro. We evaluated the efficacy of ED in the treatment of 5‑fluorouracil (5‑FU)‑induced dermatitis of nude mice, and examined the expression of pro‑inflammatory cytokines such as tumor necrosis factor‑α (TNF‑α), interleukin (IL)‑1β and IL‑6 using immunohistochemistry...

Red mulberry (Morus alba) fruit is rich in anthocyanins, and mulberry leaves are used by silk worms to make silk protein. We determined that the water and ethanol extract of mulberry fruit and silk amino acids accelerated ethanol degradation and suppressed temporal cognitive dysfunction in acute alcohol administered rats. The mechanism was explored in rats with acute oral administration of silk protein and mulberry fruit extracts. Rats were given 0.3 g of dextrin (control) and water extract (WMB) and ethanol extract of mulberry (EMB), silk protein hydrolysates (SKA), and a commercial product (positive‑control) based on body weight...

Eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome) is a rare type of anti-neutrophil cytoplasm antibody-associated vasculitis. Nevertheless, eosinophilic granulomatosis with polyangiitis stands apart because it has features of vasculitis and eosinophilic disorders that require targeted therapies somewhat different from those used for other anti-neutrophil cytoplasm antibody-associated vasculitides. Considerable advances have been made in understanding the underlying pathophysiology of eosinophilic granulomatosis with polyangiitis that have highlighted the key role of eosinophils and opened new therapeutic opportunities...

Statins are mainstream therapy in the treatment and prevention of cardiovascular disease through inhibitory effects on cholesterol synthesis. However, statins' beneficial effects in cardiovascular disease may also be attributable to their role as anti-inflammatory mediators. Here, we investigated the effects of simvastatin treatment on expression levels of interleukin (IL) 1β in both patient with hyperlipidemia and healthy human peripheral blood mononuclear cells (PBMCs) using cholesterol crystals (CC), a cardiovascular pathogenic stimulus for activation of the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome...

Neuroinflammation and microglial activation are pathological markers of a number of central nervous system (CNS) diseases. Chronic activation of microglia induces the release of excessive amounts of reactive oxygen species (ROS) and pro-inflammatory cytokines. Additionally, chronic microglial activation has been implicated in several neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease. Thymoquinone (TQ) has been identified as one of the major active components of the natural product Nigella sativa seed oil...

The influenza virus is a pathogen that can cause pandemic and epidemic outbreaks, and therefore represents a severe threat to human health. Antiviral drugs have an important role in the prevention and treatment of influenza, although the increasing emergence of drug resistance has given rise to a requirement for the development of novel antiviral drugs. In the present study, an active component (C8) isolated from Laggera pterodonta was evaluated. The nuclear magnetic resonance spectroscopy and mass spectrometry analysis results revealed that two eudesmane‑type sesquiterpene compounds were identified in C8; pterodontic acid and pterodondiol...
