Abstract
Particulate matter (PM), an environmental risk factor, is linked with health risks such as respiratory diseases. This study aimed to establish an animal model of PM-induced lung injury with artificial PM (APM) and identify the potential of APM for toxicological research. APM was generated from graphite at 600 °C and combined with ethylene. We analyzed diesel exhaust particulate (DEP) and APM compositions and compared toxicity and transcriptomic profiling in lungs according to the exposure. For the animal study, C57BL/6 male mice were intratracheally administered vehicle, DEP, or APM. DEP or APM increased relative lung weight, inflammatory cell numbers, and inflammatory protein levels compared with the vehicle control. Histological assessments showed an increase in particle-pigment alveolar macrophages and slight inflammation in the lungs of DEP and APM mice. In the only APM group, granulomatous inflammation, pulmonary fibrosis, and mucous hyperplasia were observed in the lungs of some individuals. This is the first study to compare pulmonary toxicity between DEP and APM in an animal model. Our results suggest that the APM-treated animal model may contribute to understanding the harmful effects of PM in toxicological studies showing that APM can induce various lung diseases according to different doses of APM.

Abstract
The present study aimed to identify differentially expressed genes (DEGs) and biological processes (BPs) associated with asthma. DEGs between allergic asthma and healthy controls were screened from GSE15823. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed using Database for Annotation, Visualization and Integrated Discovery. A protein-protein interaction network was constructed, followed by module mining and functional analysis. Additionally, GSE41649 was downloaded to validate the reliability of the results. In GSE41649, DEGs were identified and compared with key DEGs identified in GSE15823. A total of 43 upregulated and 275 downregulated DEGs were obtained from GSE15823. Upregulated DEGs, such as nitric oxide synthase 2 (NOS2), were enriched in BPs related to oxidation reduction. Downregulated DEGs, such as chemokine (C-C motif) ligand 19 (CCL21) and Cys-X-Cys ligand (CXCL9), were enriched in immune response-related BPs. Protein tyrosine phosphatase receptor type C (PTPRC), CCL21, and CXCL9 were identified as hub genes. The DEGs in module 1 were significantly involved in the chemokine signaling pathway (P<0.05). The expression of the key genes obtained in GSE15823 demonstrated the same variation directions in the two datasets. The immune response, oxidants and nitric oxide metabolic pathways may have important roles in the progression of asthma. DEGs of PTPRC, CCL21, CXCL9 and NOS2 may be the potential targets for asthma diagnosis and treatment.

Respirology 2016; 21:850-7. [PMID: 26991676 DOI: 10.1111/resp.12774] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2015] [Revised: 09/06/2015] [Accepted: 11/27/2015] [Indexed: 02/05/2023]
Abstract
BACKGROUND AND OBJECTIVE T lymphocytes, which are characterized by longevity and immune memory, play an important role in airway inflammation in asthma. Here, we assessed the association between immune memory and histone deacetylation and/or acetylation status. METHODS CD4 + CD45RB(low) cells (memory T (Tm)) obtained from the spleens of asthma mice models were co-cultured with glucocorticoids (GCs), trichostatin A (TSA) or anacardic acid (AA) and adoptively transferred to naïve mice. Interleukin (IL)-4, 5 and 13 and IFN-γ concentrations were measured in culture supernatants and bronchoalveolar lavage fluid (BALF). Histone deacetylase (HDAC) and histone acetyltransferase (HAT) activities and the expression of T-bet, GATA-3, HDACs 1-11 and alveolar eosinophilic inflammation index (AEII) were determined in lung tissues. RESULTS Culture supernatants and the BALF showed similar cytokine profiles. AA and GCs significantly inhibited HAT activity (P = 0.002 and P = 0.018), whereas TSA inhibited and GCs promoted HDAC activity (P = 0.004 and P = 0.025). HDACs 7, 9 and 10 were upregulated by AA and GCs (all P < 0.032), while HDAC11 was upregulated by GCs (P = 0.028). GC-induced inhibition of Tm histone acetylation alleviated AEII by downregulating IL-4, 5 and 13, similar to the effect of AA. CONCLUSION Histone hyperacetylation status induced by low expression of HDACs 7, 9 and 10 in allergen-specific Tm cells contributes to eosinophilic airway inflammation. The mechanism by which GCs improve airway inflammation involves the upregulation of HDACs 7, 9, 10 and 11 and especially HDAC-10. The role of individual HDACs and AA as novel therapeutic agents for allergic asthma needs to be explored in the future.

Abstract
Background You-Gui pills (You-Gui-Wan; YGW) can promote T lymphocyte proliferation and differentiation, and restore Th1/Th2 balance in the treatment of asthma, but their mechanism of action is not fully known. This study aims to explore whether YGW can induce histone deacetylation or acetylation in memory T lymphocytes (Tm) for improvement of airway inflammation in asthma. Methods CD4+CD45RBlow cells, as Tm, were obtained by magnetic-activated cell sorting and flow cytometry from the spleens of BALB/c mice with ovalbumin (OVA)-induced asthma. Tm were cocultured with hydrocortisone (CORT; 1000 nM), serum containing low (0.225 g/kg), moderate (0.9 g/kg), or high (3.6 g/kg) doses of YGW, or medium only, and then adoptively transferred into naïve mice (n = 5 per group). Recipient mice were challenged with aerosolized OVA. The levels of IL-4, IL-5, IL-13, and IFN-γ in culture supernatants and bronchoalveolar lavage fluid (BALF) from the OVA-challenged mice were measured by ELISA. Histone deacetylase (HDAC) and histone acetyltransferase (HAT) activities and protein expressions of T-bet, GATA-3, and HDAC1–11 in lung tissue were measured by western blotting analyses. The alveolar eosinophilic inflammation index (AEII) was evaluated in the lungs of adoptive transfer recipient mice. Results YGW reduced inflammation and eosinophil infiltration into the lung tissues as evidenced by histology, with similar effects to those of CORT. High-, moderate-, and low-YGW increased HDAC (P < 0.0001, P = 0.0009 and P = 0.0253 respectively) and decreased HAT (P = 0.0001, P = 0.0000 and P = 0.0039, respectively) activities in dose-dependent manners in the lung tissues of adoptive transfer recipient mice. Increased histone deacetylation of Tm by YGW reduced the AEII by reducing GATA-3 (P = 0.014),IL-4 (P = 0.0004), IL-5 (P = 0.0067), and IL-13 (P = 0.0002), and inducing IFN-γ release (P = 0.0375). Moreover, YGW reduced inflammatory cytokines such as IL-4, IL-5, and IL-13 by upregulating the activities of HDAC7 (P = 0.003)/10 (P = 0.003), HDAC11 (P < 0.0001), and HDAC9–11 (P < 0.0001, P < 0.0001 and P < 0.0001, respectively), respectively, and increased IFN-γ release by increasing HDAC9 (P < 0.0001). Conclusions Histone deacetylation of Tm was observed during alleviation of allergen-induced eosinophilic airway inflammation in asthma by YGW.

Abstract
OBJECTIVE To explore the effect of Astragalus membranaceus (AM) on T-helper cell type 1 (Thl) specific transcription factor T-box expressed in T cells (T-bet) expression and Thl/Th2 equilibrium. METHODS The levels of T-bet mRNA in peripheral blood mononuclear cells (PBMCs) from 15 patients with asthma and 15 healthy subjects were determined by reverse transcription-polymerase chain reaction (RT-PCR). PBMCs in asthma patients were incubated with AM and then the concentration of interferon gamma (IFN-gamma) and interleukin-4 (IL-4) in the supernate before and after AM intervention were determined by ELISA. The numbers of CD4 + CCR3 + and CD4 + CCR5 + cells were counted by flow cytometry. RESULTS The expression of T-bet mRNA and the level of IFN-gamma were lower, but level of serum IL-4 was higher in asthma patients when compared with those in healthy subjects respectively. After AM (60 microg/ml) intervention, the former two parameters raised and showed a positive correlation between them, while the level of IL-4 was decreased. The mean percentage of CD4 + CCR3 + cells in asthma patients was significantly higher but that of CD4 + CCR5 + cells was lower when compared with those in healthy subjects respectively. After AM intervention, the abnormal change in the two indexes was improved to certain extent, showing a reversing status of Th2 polarization. CONCLUSION AM could increase the expression of T-bet mRNA and Thl cytokines such as IFN-Y, and might reverse the Th2 predominant status in asthma patients.
