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

RESUMO

β-Glucan is a glucose polymer that has linkage of β-(1,3), -(1,4) and -(1,6). Exclusively found in fungal and bacterial, not in animal, cell walls, β-glucans are recognized by the innate immune system. Dendritic cells (DC) or macrophages possess pattern recognition molecules (PRM) for binding β-glucan in the pathogen-associated molecular pattern (PAMP). Recently, β-glucan receptor was cloned from DC and named dectin-1, which belongs to the type II C-type lectin family. Human dectin-1 consists of 7 exons and 6 introns.The polypeptide of dectin-1 has 247 amino acids and has cytoplasmic, transmembrane, stalk, and carbohydrate recognition domains. Dectin-1 can recognize a variety of β-1,3 and/or β-1,6 glucan linkages, but not α-glucans. In our macrophage cell line culture system, dectin-1 mRNAwas detected in RAW264.7 cells by a reverse transcription/polymerase chain reaction (RT-PCR). Dectin-1 was also detected in the murine organs of spleen, thymus, lung, and intestine. Treatment of RAW264.7 cells with β-glucans of Ganoderma lucidum (GLG) resulted in increased expression of IL-6 and TNF-α in the presence of LPS. However, GLG alone did not increase IL-6 or TNF-α. These results suggest that receptor dectin-1 cooperates with CD14 to activate signal transduction, which is very critical in immunoresponses.
