Abstract
Sodium aescinate (SA) is a vital salt of sodium escin from Aesculus wilsonii Rehd seeds. SA injection (SAI) has received great success in treating cerebral edema, venous reflux disease and other inflammatory conditions. Recently, high incidences of immediate hypersensitivity reactions were reported after SA infusion, which raised questions on safety and risk associated with its clinical application. This study was designed to check whether SAI and its four components induce degranulation using RBL-2H3 mast cells. For this purpose, we evaluated different treatment levels of SAI (20, 40, 60, 80 and 100 μg ml-1) and its four characteristic components, SA-A, SA-B, SA-C and SA-D, at 60 μg ml-1 in different tests including cell viability test, β-hexosaminidase and histamine assays, oxidative stress indices, apoptosis analysis and intracellular calcium ions in RBL-2H3 cells. Our results demonstrated that SAI at 80 μg ml-1 and 100 μg ml-1, and its two components (SA-B and SA-D) at 60 μg ml-1 were responsible for disturbing cell morphology and cell viability, elevated levels of β-hexosaminidase, histamine, modulation of oxidative stress indices, induced apoptosis and increase in intracellular calcium ions in RBL-2H3 cells, when compared with the control. Our results demonstrated for the first time that SAI was more likely to induce immediate hypersensitivity reactions attributable to degranulation via oxidative stress caused by SA-B and SA-D components. These results would not only be useful for the safety of end user but also for the industry to improve the quality of SA infusion.

Abstract
Genome-wide association studies have identified common genetic variants impacting human diseases; however, there are indications that the functional consequences of genetic polymorphisms can be distinct depending on cell type-specific contexts, which produce divergent phenotypic outcomes. Thus, the functional impact of genetic variation and the underlying mechanisms of disease risk are modified by cell type-specific effects of genotype on pathological phenotypes. In this study, we extend these concepts to interrogate the interdependence of cell type- and stimulation-specific programs influenced by the core autophagy gene Atg16L1 and its T300A coding polymorphism identified by genome-wide association studies as linked with increased risk of Crohn's disease. We applied a stimulation-based perturbational profiling approach to define Atg16L1 T300A phenotypes in dendritic cells and T lymphocytes. Accordingly, we identified stimulus-specific transcriptional signatures revealing T300A-dependent functional phenotypes that mechanistically link inflammatory cytokines, IFN response genes, steroid biosynthesis, and lipid metabolism in dendritic cells and iron homeostasis and lysosomal biogenesis in T lymphocytes. Collectively, these studies highlight the combined effects of Atg16L1 genetic variation and stimulatory context on immune function.

Abstract
Background Investigating the factors that influence Acinetobacter baumannii(Ab) adhesion/invasion of host cells is important to understand its pathogenicity. Metal cations have been shown to play an important role in regulating the biofilm formation and increasing the virulence of Ab; however, the effect of calcium on host-bacterial interaction has yet to be clarified. Here, the dynamic process of the interaction between Ab and human respiratory epithelial cells and the effect of calcium on host-bacterial interaction were explored using microscopic imaging, quantitative PCR and real time cellular analysis (RTCA). Results The concentration of calcium, multiplicity of infection and co-culture time were all demonstrated to have effects on host-bacterial interaction. A unique “double peak” phenomenon changed to a sharp “single peak” phenomenon during the process of Ab infection under the effect of calcium was observed in the time-dependent cell response profiles. Moreover, calcium can increase Ab adhesion/invasion of epithelial cells by regulating the expression of Ab-related genes (ompA, bfmRS, abaI). Conclusions Effective control of calcium concentrations can provide new approaches for the prevention and treatment of multi-drug resistant Ab.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The concept of the prescription in Traditional Chinese Medicine (TCM) is usually characterized by the compatibility principle "monarch, minister, assistant, and guide", which means herbs play primary, secondary, auxiliary, or harmonic roles, respectively, to achieve the optimally holistic effect. Following this compatibility principle, the Tanyu Tongzhi Formula (TTF), used for many years to treat cardiovascular diseases, has been proved effective clinically and experimentally. AIM OF THE STUDY The ancient compatibility principle is based on experiences, but whether its underlying interactions can be explained at the cellular level is unknown. We aimed to explore the mechanisms of activity of the TTF herbs and the interactions between them. MATERIALS AND METHODS We used a real-time cell analyzer to record the responses of COS-7 cells to the herbs in TTF, both individually and in different combinations. We also used biochemical assays to further characterize the TTF activity. RESULTS Monarch herb Fructus trichosanthis acts as an inhibitor of the EGF signaling. It's cytotoxicity, derived from inhibition of tubulin polymerization, could be completely neutralized by the combination of the phlegm group, or the whole TTF combination. Meanwhile, the minister, assistant, and guide herbs in the TTF did not affect EGF signaling. CONCLUSION Our results provide a demonstration, at the cellular level, of the compatibility principle of "monarch, minister, assistant, and guide" in TTF. Under the guidance of this principle, TTF exerts the anti-inflammation and anti-tumor effects through inhibiting EGF signaling, while avoiding the microtubule-disrupting activity of Fructus trichosanthis.

Abstract
BACKGROUND Recently, we have shown that mast cell mitochondrial STAT3 could serve as a new target for the regulation of the allergic response as it plays an essential role in immunologically mediated degranulation of mast cells. In the present work, we explored how two recently developed mitochondrial STAT3 inhibitors (Mitocur-1 and Mitocur-3) modulate the allergic response. METHODS Experiments were performed both in vitro in cultured human/mouse mast cells and with rat basophilic leukemia (RBL) cells and also in vivo in mice. The effect of mitochondrial STAT3 inhibition on mast cell function was determined via checking degranulation and several cytokines secretion levels. RESULTS Here, we show that treatment of rodent and human cultured mast cells with low concentrations of mitochondrial STAT3 inhibitors had no effect on STAT3 target gene expression. However, these inhibitors caused a significant reduction in mast cell exocytosis and cytokine release, due to a decrease in OXPHOS activity and STAT3 serine 727 phosphorylation. It was also observed in an OVA mouse model of allergic asthma that one of the inhibitors used significantly reduced eosinophilia and neutrophilia compared to the control mice group. Furthermore, it was observed that treatment with this inhibitor resulted in a significant reduction in blood histamine levels in mice after IgE-Ag challenge. CONCLUSION The present data strongly suggest that the development of mitochondrial STAT3 inhibitors could serve as a potential treatment for allergy-associated diseases.

Abstract
The use of impedance-based label free cell analysis is increasingly popular and has many different applications. Here, we report that a real-time cell analyzer (RTCA) can be used to study the stimulation of Natural Killer (NK) cells. Engagement of NK cells via plate-bound antibodies directed against different activating surface receptors could be measured in real time using the label-free detection of impedance. The change in impedance was dependent on early signal transduction events in the NK cells as it was blocked by inhibitors of Src-family kinases and by inhibiting actin polymerization. While CD16 was the only receptor that could induce a strong change in impedance in primary NK cells, several activating receptors induced changes in impedance in expanded NK cells. Using PBMCs we could detect T cell receptor-mediated T cell activation and CD16-mediated NK cell activation in the same sample. Performing a dose-response analysis for the Src-family kinases inhibitor PP1 we show that T cells are more sensitive to inhibition compared to NK cells. Our data demonstrate that the RTCA can be used to detect physiological activation events in NK cells in a label-free and real-time fashion.

Abstract
Perfluorinated compounds (PFC) have widely been used in numerous applications including clothing, food packaging, and nonstick coating. With the widespread use of PFC, concerns regarding potential adverse health effects in humans and wildlife have increased. In spite of the known PFC-mediated immunotoxiciy, correlation with PFC and allergic inflammation still requires elucidation. The aim of this study was to examine the effect of four types of PFC (perfluoroheptanoic acid [PFHpA], perfluorononanoic acid [PFNA], perfluorodecanoic acid [PFDA], and perfluoroundecanoic acid [PFUnA]) on mast cell-mediated allergic inflammation in the presence of high-affinity immunoglobulin (Ig) E receptor (FcεRI) cross-linking. Among PFC family, long-chain PFDA and PFUnA increased release of histamine and β-hexosaminidase by up-regulation of intracellular calcium levels in IgE-stimulated mast cells. In addition, PFDA and PFUnA enhanced gene expression of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-8 by activation of nuclear factor-κB in IgE-stimulated mast cells. In ovalbumin (OVA)-induced model of systemic anaphylaxis in the presence of hypothermia, PFNA, PFDA, and PFUnA exacerbated allergic symptoms accompanied by elevation in serum histamine, TNF-α, IgE, and IgG1. Our data indicate that some PFC aggravated high-affinity IgE receptor (FcεRI)-mediated mast cell degranulation and allergic symptoms. Consequently, the results demonstrated that carbon-chain length of PFC may serve as a factor in allergic inflammation.
