Objectives Scope Due to the plasticity, macrophage as a heterogeneous population of immune cells could modify their phenotype rapidly as response to environmental factors. We differentiated primary macrophages to classic macrophages or alternative macrophages and analysed cell typespecific markers as well as those markers that response to dietary fibers. Some of these fibers for example given the beta-glucan Lentinan from Shiitake mushroom, have shown immunomodulating properties towards macrophages whichmight be expected to be revealed by these analysis. Methods Macrophages were obtained after 7 days culturing of monocytes in RPMI-1640 medium supplemented with 50 ng/ml MCSF(referred to as M(MCSF) and followed polarization by 20 ng/ml TNF-α plus 20 ng/ml IFN-γ or 20 ng/ml IL-4 for M(TNF-α + IFN-γ) and M(IL4) separately. Gene expression profiles of macrophages were analysed by Affymetrix GeneC hips(Human gene 1.1 ST Array) and verified mR NA expression by q ***,M(MCSF)were incubated with Lentinan containing Shiitake extract at 500μg/ml for the same 18 hours. Results Comparing M(TNF-α + IFN-γ) to M(IL4), we identified 8639 significant differencially expressing genes. According to those genes, IDO1, IRG1, ANKRD22, GBP5 and GBP3 were the top 5 markers for M(TNF-α + IFN-γ). Meanwhile, IL17 RB, ALOX5, CD180, ST8SIA6 and CHDH were the top 5 markers for M(IL4). Interestingly, indoleamine 2,3-dioxygenase(IDO) is an immunomodulatory protein expressed in various antigen presenting cells such as macrophages and dendritic cells, which can suppress adaptive immunity and showed T cells suppression and immune tolerance activity. Further, we verified IDO1 m RNA expression by q PCR, normalized to medium control, which confirmed that M(TNF-α + IFN-γ)highly express IDO1 while M(IL4) do not. IDO1 expression was also increased by incubation with theL entinancontaining extract of Shiitake mushroom.. Conclusion Our findings indicate that IDO1 is a potential biomarker for ident

有机-无机钙钛矿材料因其优良的光学性能、高扩散系数、高载流子迁移率,已经成为光伏电池的新兴材料。为实现太阳能电池的商业化,钙钛矿材料的合成显得尤为重要。本文在溶液合成法中,通过调节CH3NH3I与CH3NH3Br的摩尔比,成功制备了高结晶、无孔洞的CH3NH3PbI3-xBrx钙钛矿薄膜,表现出优于纯CH3NH3PbI3和CH3NH3PbBr3薄膜的电池性能。同时,本文讨论了溴元素引入及含量变化对钙钛矿的晶体结构、薄膜形貌、光学特性的影响。结果表明,通过引入适量的Br元素,调节了CH3NH3PbI3-xBrx钙钛矿的晶格参数和带隙,提高了钙钛矿的稳定性,进而改善了钙钛矿太阳能电池的光电性能。
