Wild variety (wt) and LLO deficient (hly) L. monocytogenes bacteria grown in EUcontaining medium and coupled to Alexa Fluor 488 azide. Fluorescence of EU/Alexa Fluor 488 azidelabeled RNA was measured in option. Background fluorescence of nonEU containing RNA soon after the ClickiT reaction was subtracted from EU containing RNA and normalized on fluorescence of RNA from wt L. monocytogenes. Imply valuess.d. ( of wt RNA) of 3 independent experiments are shown. THP1 cells were grown for 12 hrs in starvation medium (RPMI without FCS) (C) or in common medium (D) and after that incubated for 4 hrs with equal concentrations of EU. Cells had been fixed and EUlabeled RNA counterstained with Alexa 594. (EPS)Figure S3 Release of bacterial RNA in to the cytosol depends on the SecA2 secretion technique. THP1 have been infected with FITCtagged and EUlabeled wild variety (L.m.wt; left column) and SecA2 deficient (L.m. SecA; left column) L. monocytogenes for two hours. Cells were then fixed, stained with Alexa594azide and counterstained with DAPI. Entire L. monocytogenes are labeled green with FITC and RNA is visible as red fluorescence (Alexa594), nuclei are stained by DAPI (blue). Three examples per condition are shown. As determined by counting of single stained bacteria in cells (one hundred cells per slide have been counted) the typical bacterial load was 0.Perfluorohexyloctane Order five(wt) and 0.five(SecA) bacteria per cell. One representative experiment out of 3 is shown. (EPS) Figure S4 A: A549 cells have been transfected with siRNA against RIGI, MAVS or maybe a manage sequence. Cells have been then infected with L. monocytogenes 40 hours right after knockdown. Sort I IFN production was analyzed 24 hours just after stimulation. B: mRNA expression levels of RIGI (left panel) or MAVS (appropriate panel) normalized on GAPDH expression, 40 h right after transfection of siRNAs into A549 cells. C: mRNA expression levels of STING (left panel) or MAVS (right panel) normalized of GAPDH expression, 72 h soon after electroporation. Error bars represent s.d. (EPS)Acknowledgments Fluorescence MicroscopyFreshly trypsinized and washed A549 or HepG2 have been seeded at the appropriate concentrations onto uncoated coverslips, then left to adhere for three hours at 37uC. FITCtagged and EUlabeled L. monocytogenes had been then added to the cells and left for infection for the indicated duration. Soon after fixation and remedy with the ClickiT reaction cocktail, cells were washed with PBS and counterstained with DAPI (Thermo scientific). THP1 cells were infected and stained in solution and resuspended in mounting medium. Cells have been then visualized employing a fluorescence microscope (Zeiss).We thank Jasper van den Boorn and Percy Knolle for essential reading of the manuscript and T.
