Abstract: On recognition of influenza virus (Flu) by TLR7, plasmacytoid dendritic cells (pDCs) produce type I IFN in significant amounts. Synthetic TLR7 ligands induce the maturation of pDCs, as evidenced by the expression of costimulatory molecules and the production of proinflammatory cytokines; however, they induce only low-level production of IFN-alpha. To dissect the TLR7 signaling in pDCs and how these different profiles are induced, we studied the effects of 2 TLR7 ligands (Flu and CL097) on the activation of blood-isolated pDCs and the human GEN2.2 pDC cell line. Type I IFN production by pDCs correlates with differential interferon regulatory factor 7 (IRF7) translocation into the nucleus induced by the 2 TLR7 ligands. Surprisingly, with both activators we nevertheless observed the rapid expression of the IFN-inducible genes mxa, cxcl10, and trail within 4 hours of stimulation. This expression, controlled by STAT1 phosphorylation, was independent of type I IFN. STAT1 activation was found to be strictly dependent on the PI3K-p38MAPK pathway, showing a new signaling pathway leading to rapid expression of IFN-inducible genes after TLR7 triggering. Thus, pDCs, through this unusual TLR7 signaling, have the capacity to promptly respond to viral infection during the early phases of the innate immune response..

Abstract: Chromatin allows the eukaryotic cell to package its DNA efficiently. To understand how chromatin structure is controlled across the Saccharomyces cerevisiae genome, we have investigated the role of the ATP-dependent chromatin remodelling complex Isw2 in positioning nucleosomes. We find that Isw2 functions adjacent to promoter regions where it repositions nucleosomes at the interface between genic and intergenic sequences. Nucleosome repositioning by Isw2 is directional and results in increased nucleosome occupancy of the intergenic region. Loss of Isw2 activity leads to inappropriate transcription, resulting in the generation of both coding and noncoding transcripts. Here we show that Isw2 repositions nucleosomes to enforce directionality on transcription by preventing transcription initiation from cryptic sites. Our analyses reveal how chromatin is organized on a global scale and advance our understanding of how transcription is regulated..

Abstract: The physiology of ethanologenic Escherichia coli grown anaerobically in alkali-pretreated plant hydrolysates is complex and not well studied. To gain insight into how E. coli responds to such hydrolysates, we studied an E. coli K-12 ethanologen fermenting a hydrolysate prepared from corn stover pretreated by ammonia fiber expansion. Despite the high sugar content (6% glucose, 3% xylose) and relatively low toxicity of this hydrolysate, E. coli ceased growth long before glucose was depleted. Nevertheless, the cells remained metabolically active and continued conversion of glucose to ethanol until all glucose was consumed. Gene expression profiling revealed complex and changing patterns of metabolic physiology and cellular stress responses during an exponential growth phase, a transition phase, and the glycolytically active stationary phase. During the exponential and transition phases, high cell maintenance and stress response costs were mitigated, in part, by free amino acids available in the hydrolysate. However, after the majority of amino acids were depleted, the cells entered stationary phase, and ATP derived from glucose fermentation was consumed entirely by the demands of cell maintenance in the hydrolysate. Comparative gene expression profiling and metabolic modeling of the ethanologen suggested that the high energetic cost of mitigating osmotic, lignotoxin, and ethanol stress collectively limits growth, sugar utilization rates, and ethanol yields in alkali-pretreated lignocellulosic hydrolysates..
