Abstract
The aim of this study was to investigate the anti-inflammatory activity of a previously un-studied wild mushroom, Echinodontium tinctorium, collected from the forests of north-central British Columbia. The lipopolysaccharide (LPS)-induced RAW264.7 macrophage model was used to study the in vitro anti-inflammatory activity. The crude alkaline extract demonstrated potent anti-inflammatory activity, and was further purified using a “bio-activity-guided-purification” approach. The size-exclusion and ion-exchange chromatography yielded a water-soluble anti-inflammatory polysaccharide (AIPetinc). AIPetinc has an average molecular weight of 5 kDa, and is a heteroglucan composed of mainly glucose (88.6%) with a small amount of galactose (4.0%), mannose (4.4%), fucose (0.7%), and xylose (2.3%). In in vivo settings, AIPetinc restored the histamine-induced inflammatory event in mouse gluteus maximus muscle, thus confirming its anti-inflammatory activity in an animal model. This study constitutes the first report on the bioactivity of Echinodontium tinctorium, and highlights the potential medicinal benefits of fungi from the wild forests of northern British Columbia. Furthermore, it also reiterates the need to explore natural resources for alternative treatment to modern world diseases.

Abstract Mushrooms have been used extensively, owing to their nutritional and medicinal value, for thousands of years. Modern research confirms the therapeutic effect of traditionally used species. Inflammation is a natural response of the immune system to damaging factors, e.g. physical, chemical and pathogenic. Deficiencies of antioxidants, vitamins, and microelements, as well as physiological processes, such as aging, can affect the body’s ability to resolve inflammation. Mushrooms are rich i...

In our previous work, Asterina pectinifera was fermented with Cordyceps militaris mycelia to improve its bioactivities and was reported to have strong antioxidant activities. The aim of the current study was to investigate its anti-inflammatory effect and mechanisms of action. In this study, we observed the inhibitory effect of the extract from fermented A. pectinifera with C. militaris mycelia (FACM) on nitric oxide (NO) production and its molecular mechanism in lipopolysaccharide (LPS)-stimula...

The phylogenetic relationship of eight species of Echinodontium, Laurilia, and Perplexostereum of Russulales were analyzed based on sequences of the nuc rDNA ITS1-5.8S-ITS2 (ITS [internal transcribed spacer]) and D1–D2 domains of nuc 28S rDNA (28S). Our results show that Echinodontium tinctorium, E. ryvardenii, and E. tsugicola represent Echinodontium sensu stricto. Based on morphological and phylogenetic evidence, the new genus Echinodontiellum is established to accommodate Echinodontium japoni...

Abstract Background In the recent years natural resources are being in focus due to their great potential to be exploited in the discovery/development of novel bioactive compounds and, among them, mushrooms can be highlighted as alternative sources of anti-inflammatory agents. Scope and approach The present review reports the anti-inflammatory activity of mushroom extracts and of their bioactive metabolites involved in this bioactive action. Additionally the most common assays used to evaluate m...

Thirty years after the discovery of its production by activated macrophages, our appreciation of the diverse roles of nitric oxide (NO) continues to grow. Recent findings have not only expanded our understanding of the mechanisms controlling the expression of NO synthases (NOS) in innate and adaptive immune cells, but have also revealed new functions and modes of action of NO in the control and escape of infectious pathogens, in T and B cell differentiation, and in tumor defense. I discuss these...

Abstract Inflammation is the first response of the body's immune system to injury, infection and stress. Chronic inflammation has close relationship with many diseases, such as arthritis, atherosclerosis and cancer. The traditional therapy strategy of inflammation mainly involves steroid and non-steroid anti-inflammatory drugs, both of which have increasingly prominent side-effects which cannot be ignored. Polysaccharides extracted from natural sources have attracted extensive attention in recen...
