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

ABSTRAKT

Piptoporus betulinus, the mushroom that has been carried by Ötzi the "Iceman", has a long tradition of use in medicinal practice for its antiseptic, anticancer, and immune-enhancing properties. With this study, we aimed to investigate the immunomodulatory effects of P. betulinus on primary human immunocompetent cells. The influence of P. betulinus water and methanol extract on apoptosis and necrosis induction of T cells and monocytes was analyzed using annexin V/propidium iodide staining and proliferation of T cells by carboxyfluorescein diacetate succinimidyl ester staining using flow cytometry. The effects on T-cell activation (CD69/CD25) and dendritic cell maturation (CD83, CD86, and CD14) were assessed using flow cytometric analysis of distinct marker expression. Alterations of the secretion of effector mediators interferon (IFN)-γ by T cells and interleukin (IL)-8 by monocytes and dendritic cells were detected by enzyme-linked immunosorbent assay. None of the P. betulinus extracts had a significant influence on apoptosis and necrosis induction, T-cell proliferation, or T-cell activation status, but P. betulinus water extract caused a strong increase in IFN-γ release. The same extract was slightly protective against apoptosis of monocytes and further triggered IL-8 secretion by monocytes and dendritic cells. Moreover, P. betulinus water extract induced dendritic cell maturation. Our results demonstrate the immune-enhancing properties of P. betulinus.
