杨老师:

想自己买台电脑学习生物信息,配置方面有什么要注意的?台式?笔记本?显卡?内存?

我是入门级别,生物学背景。

谢谢
我的回复(2013-5-14 16:35):入门学习,普通台式电脑即可。

摘 要:During a systemic inflammatory response endothelial-expressed surface molecules have been strongly implicated in orchestrating immune responses. Previous studies have shown enhanced extracellular nucleotide release during acute inflammatory conditions. Therefore, we hypothesized that endothelial nucleotide receptors could play a role in vascular inflammation. To address this hypothesis, we performed screening experiments and exposed human microvascular endothelia to inflammatory stimuli, followed by measurements of P2Y or P2X transcriptional responses. These studies showed a selective induction of the P2Y6 receptor (> 4-fold at 24 hours). Moreover, studies that used real-time reverse transcription–polymerase chain reaction, Western blot analysis, or immunofluorescence confirmed time- and dose-dependent induction of P2Y6 with tumor necrosis factor α or Lipopolysaccharide (LPS) stimulation in vitro and in vivo. Studies that used MRS 2578 as P2Y6 receptor antagonist showed attenuated nuclear factor κB reporter activity and proinflammatory gene expression in human microvascular endothelial cells in vitro. Moreover, pharmacologic or genetic in vivo studies showed attenuated inflammatory responses in P2Y6−/− mice or after P2Y6 antagonist treatment during LPS-induced vascular inflammation. These studies show an important contribution of P2Y6 signaling in enhancing vascular inflammation during systemic LPS challenge and implicate the P2Y6 receptor as a therapeutic target during systemic inflammatory responses.
