| 1 | Effect of Helicobacter pylori on gastric epithelial cells显示文摘The gastrointestinal epithelium has cells with features that make them a powerful line of defense in innate mucosal immunity. Features that allow gastrointestinal epithelial cells to contribute in innate defense include cell barrier integrity, cell turnover, autophagy, and innate immune responses. Helicobacter pylori(H. pylori) is a spiral shape gram negative bacterium that selectively colonizes the gastric epithelium of more than half of the world's population. The infection invariably becomes persistent due to highly specialized mechanisms that facilitate H. pylori 's avoidance of this initial line of host defense as well as adaptive immune mechanisms. The host response is thus unsuccessful in clearing the infection and as a result becomes established as a persistent infection promoting chronic inflammation. In some individuals the associated inflammation contributes to ulcerogenesis or neoplasia. H. pylori has an array of different strategies to interact intimately with epithelial cells and manipulate their cellular processes and functions. Among the multiple aspects that H. pylori affects in gastric epithelial cells are their distribution of epithelial junctions, DNA damage, apoptosis, proliferation, stimulation of cytokine production, and cell transformation. Some of these processes are initiated as a result of the activation of signaling mechanisms activated on binding of H. pylori to cell surface receptors or via soluble virulence factors that gain access to the epithelium. The multiple responses by the epithelium to the infection contribute to pathogenesis associated with H. pylori. | Shatha Alzahrani Taslima T Lina Jazmin Gonzalez Irina V Pinchuk Ellen J Beswick Victor E Reyes | 2014 | World Journal of Gastroenterology2014，20，36： | 15 |
| 2 | Immune evasion strategies used by Helicobacter pylori显示文摘Helicobacter pylori(H. pylori) is perhaps the most ubiquitous and successful human pathogen, since it colonizes the stomach of more than half of humankind. Infection with this bacterium is commonly acquired during childhood. Once infected, people carry the bacteria for decades or even for life, if not treated. Persistent infection with this pathogen causes gastritis, peptic ulcer disease and is also strongly associated with the development of gastric cancer. Despite induction of innate and adaptive immune responses in the infected individual, the host is unable to clear the bacteria. One widely accepted hallmark of H. pylori is that it successfully and stealthily evades host defense mechanisms. Though the gastric mucosa is well protected against infection, H. pylori is able to reside under the mucus, attach to gastric epithelial cells and cause persistent infection by evading immune responses mediated by host. In this review, we discuss how H. pylori avoids innate and acquired immune response elements, uses gastric epithelial cells as mediators to manipulate host T cell responses and uses virulence factors to avoid adaptive immune responses by T cells to establish a persistent infection. We also discuss in this review how the genetic diversity of this pathogen helps for its survival. | Taslima T Lina Shatha Alzahrani Jazmin Gonzalez Irina V Pinchuk Ellen J Beswick Victor E Reyes | 2014 | World Journal of Gastroenterology2014，20，36： | 7 |
| 3 | Innate and adaptive immune responses in male and female reproductive tracts in homeostasis and following HIV infection显示文摘男、女的繁殖的道是有多样的功能的要求的复杂微型环境。当同时对潜在的病原体授与保护时,在繁殖的道的免疫系统举办为胎儿的 allograft 提供保护的环境的费力的任务。因此,它发展了改编的一个唯一的集合,首先在性荷尔蒙的影响下面,它从另外的 mucosal 地点使它不同。这里,我们讨论在男性和女繁殖的道是在场的免疫系统的各种各样的部件,包括在 homeostatic 条件下面的天生的可溶的因素和房间和体液、调停房间的适应免疫。我们考察在从全身的豁免展出区分并且讨论这些特征怎么被性荷尔蒙影响的男、女的繁殖的道显示出唯一的 phenotypic 和有免疫力的房间和回答的功能的特征的证据。我们也在跟随 HIV-1 感染的繁殖的道,性荷尔蒙和有免疫力的回答之中检验相互作用。男、女的繁殖的道的唯一的特征的改进理解将提供卓见进为性播送的感染的预防改进不孕的免疫学的原因和预防干预的设计的临床的处理。 | Philip V Nguyen Jessica K Kafka Victor H Ferreira Kristy Roth Charu Kaushic | 2014 | Cellular & Molecular Immunology2014，11，5： | 7 |
| 4 | Dynamic chromatin states in human ES cells reveal potential regulatory sequences and genes involved in pluripotency显示文摘Pluripotency,一个细胞的能力区分并且产生所有胚胎的系,定义象胚胎的茎(ES ) 那样的哺乳动物的细胞类型的一个小数字细胞。当它通常被保持了时,那 pluripotency 是 transcriptional 的产品激活并且维持关键干细胞基因的表达式的规章的网络,积累的证据在建立并且保卫 ES 房间的 pluripotency 为 epigenetic 进程正在指向一个关键角色,象维持区分的房间类型的身份一样。以便更好在 pluripotency 理解 epigenetic 机制的角色,我们检验了在经历区别进一个 mesendodermal 系的人的 ES 房间(hESCs ) 染色体宽的染色质修正的动力学。我们发现在倡导者的染色质修正在区别期间仍然保持大部分不变,除了在在在 H3K27 的 acetylation 和 methylation 之间的一个动态开关标记在基因表示的激活和 silencing 之间的转变的倡导者的一个小数字,建议在在大多数差别上的房间命运承诺的一个层次表示了基因。我们也在 50 000 潜在的 enhancers 上印射,并且在染色质修正,特别 H3K4me1 和 H3K27ac 观察了大得多的动力学,它与他们的潜在的目标基因的表示相关。这些 enhancers 的进一步的分析揭示了 pluripotency 和可以在 hESCs 授与发展胜任的一个平衡状态的一口染色质签名陈述语气的潜在地关键的 transcriptional 管理者。我们的结果提供在定义 enhancers 和 pluripotency 支持染色质修正的角色的新证据。 | R David Hawkins Gary C Hon Chuhu Yang Jessica E Antosiewicz-Bourget Leonard K Lee Que-Minh Ngo Sarit Klugman Keith A Ching Lee E Edsall Zhen Ye Samantha Kuan Pengzhi Yu Hui Liu Xinmin Zhang Roland D Green Victor V Lobanenkov Ron Stewart James A Thomson Bing Ren | 2011 | Cell Research2011，21，10： | 6 |
