The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

摘要

In the US market, there is a variety of mushroom preparations available, even within the same species of mushroom. Nonetheless, little is known about whether species or the various extraction methods affect biological activity and potency of the immune modulatory activity of mushroom extracts. After discovering that protein-bound polysaccharide-K, a hot water extract from Trametes versicolor, was a potent Toll-like receptor (TLR)-2 agonist that stimulates both innate and adaptive immunity, this study was initiated to evaluate whether other medicinal mushroom products also have TLR2 agonist activity and immune-enhancing potential as measured by the induction of tumor necrosis factor (TNF)-α in J774.A1 murine macrophage cells. Furthermore, the products were divided by extraction method and species to determine whether these factors affect their immunomodulatory activity. The results showed that the majority (75%) of mushroom products tested had TLR2 agonist activity and that there was a significant correlation between TLR2 agonist activity and TNF-α induction potential in the mushroom products analyzed. In addition, the data demonstrated that hot water mushroom extracts are more potent than ground mushroom products in activating TLR2 and inducing TNF-α. These data provide evidence that extraction methods may affect the biological activity of mushroom products; thus, further studies are warranted to investigate the structural differences between various mushroom products.
