The FimH amino acids involved in CD14 binding are highly conserved across pathogenic and non-pathogenic strains. Binding of the pathogenic strain CFT073 to CD14 reduced DC migration by overactivation of integrins and blunted expression of co-stimulatory molecules by overactivating the NFAT (nuclear factor of activated T-cells) pathway, both rate-limiting factors of T cell activation. This response was binary at the single-cell level, but averaged in larger populations exposed to both piliated and non-piliated pathogens, presumably via the exchange of immunomodulatory cytokines.

Some of these interactions such as those of transcription factors and promoters have been studied extensively. However, predicting phenotypes of gene regulatory networks (GRNs) remains a major challenge. Here, we use a well-defined synthetic GRN to study in Escherichia coli how network phenotypes depend on local genetic context, i.e. the genetic neighborhood of a transcription factor and its relative position. We show that one GRN with fixed topology can display not only quantitatively but also qualitatively different phenotypes, depending solely on the local genetic context of its components. Transcriptional read-through is the main molecular mechanism that places one transcriptional unit (TU) within two separate regulons without the need for complex regulatory sequences. We propose that relative order of individual TUs, with its potential for combinatorial complexity, plays an important role in shaping phenotypes of GRNs.","lang":"eng"}],"corr_author":"1","file_date_updated":"2021-03-23T10:12:58Z","ec_funded":1,"doi":"10.7554/elife.65993","publication_status":"published","publication":"eLife","type":"journal_article","date_updated":"2025-06-12T06:36:17Z","scopus_import":"1","ddc":["570"],"article_processing_charge":"Yes","article_type":"original"},{"doi":"10.15479/at:ista:10307","publication_status":"published","file_date_updated":"2022-12-20T23:30:05Z","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Bacteria-host interactions represent a continuous trade-off between benefit and risk. Thus, the host immune response is faced with a non-trivial problem – accommodate beneficial commensals and remove harmful pathogens. This is especially difficult as molecular patterns, such as lipopolysaccharide or specific surface organelles such as pili, are conserved in both, commensal and pathogenic bacteria. Type 1 pili, tightly regulated by phase variation, are considered an important virulence factor of pathogenic bacteria as they facilitate invasion into host cells. While invasion represents a de facto passive mechanism for pathogens to escape the host immune response, we demonstrate a fundamental role of type 1 pili as active modulators of the innate and adaptive immune response."}],"supervisor":[{"first_name":"Michael K","last_name":"Sixt","full_name":"Sixt, Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X"},{"full_name":"Guet, Calin C","orcid":"0000-0001-6220-2052","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","last_name":"Guet","first_name":"Calin C"}],"corr_author":"1","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"},{"_id":"PreCl"},{"_id":"EM-Fac"}],"oa":1,"day":"18","year":"2021","alternative_title":["ISTA Thesis"],"title":"Pathogenic Escherichia coli hijack the host immune response","article_processing_charge":"No","degree_awarded":"PhD","ddc":["570"],"type":"dissertation","date_updated":"2026-04-08T07:14:01Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","oa_version":"Published Version","related_material":{"record":[{"id":"10316","status":"public","relation":"part_of_dissertation"}]},"OA_place":"publisher","author":[{"orcid":"0000-0003-3768-877X","full_name":"Tomasek, Kathrin","id":"3AEC8556-F248-11E8-B48F-1D18A9856A87","first_name":"Kathrin","last_name":"Tomasek"}],"file":[{"access_level":"open_access","relation":"main_file","date_created":"2021-11-18T15:07:31Z","file_name":"ThesisTomasekKathrin.pdf","checksum":"b39c9e0ef18d0484d537a67551effd02","file_size":13266088,"embargo":"2022-11-18","file_id":"10308","date_updated":"2022-12-20T23:30:05Z","content_type":"application/pdf","creator":"ktomasek"},{"date_created":"2021-11-18T15:07:46Z","access_level":"closed","relation":"source_file","file_name":"ThesisTomasekKathrin.docx","embargo_to":"open_access","checksum":"c0c440ee9e5ef1102a518a4f9f023e7c","file_size":7539509,"date_updated":"2022-12-20T23:30:05Z","file_id":"10309","creator":"ktomasek","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document"}],"has_accepted_license":"1","month":"11","status":"public","page":"73","date_created":"2021-11-18T15:05:06Z","department":[{"_id":"MiSi"},{"_id":"CaGu"},{"_id":"GradSch"}],"publisher":"Institute of Science and Technology Austria","citation":{"apa":"Tomasek, K.

Using a variety of constitutively expressed fluorescent proteins in Escherichia coli K-12 strain MG1655, we found strong artifactual changes in fluorescence levels after dilution into the commonly used flow cytometry buffer phosphate-buffered saline (PBS) and two other buffer solutions, Tris-HCl and M9 salts. These changes appeared very rapidly after dilution, and were linked to increased membrane permeability and loss in cell viability. We observed buffer-related effects in several different E. coli strains, K-12, C and W, but not E. coli B, which can be partially explained by differences in lipopolysaccharide (LPS) and outer membrane composition. Supplementing the buffers with divalent cations responsible for outer membrane stability, Mg2+ and Ca2+, preserved fluorescence signals, membrane integrity and viability of E. coli. Thus, stabilizing the bacterial outer membrane is essential for precise and unbiased measurements of fluorescence parameters using flow cytometry."}],"corr_author":"1","language":[{"iso":"eng"}],"publist_id":"7317","title":"Lack of cations in flow cytometry buffers affect fluorescence signals by reducing membrane stability and viability of Escherichia coli strains","volume":268,"year":"2018","day":"20"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.15479/AT:ISTA:53","oa_version":"Published Version","related_material":{"record":[{"relation":"research_paper","id":"665","status":"public"}]},"file_date_updated":"2020-07-14T12:47:03Z","author":[{"id":"2C471CFA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5396-4346","full_name":"Bergmiller, Tobias","first_name":"Tobias","last_name":"Bergmiller"},{"id":"2B8A40DA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2912-6769","full_name":"Andersson, Anna M","first_name":"Anna M","last_name":"Andersson"},{"full_name":"Tomasek, Kathrin","id":"3AEC8556-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3768-877X","first_name":"Kathrin","last_name":"Tomasek"},{"full_name":"Balleza, Enrique","last_name":"Balleza","first_name":"Enrique"},{"first_name":"Daniel","last_name":"Kiviet","full_name":"Kiviet, Daniel"},{"last_name":"Hauschild","first_name":"Robert","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9843-3522","full_name":"Hauschild, Robert"},{"first_name":"Gasper","last_name":"Tkacik","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","full_name":"Tkacik, Gasper","orcid":"0000-0002-6699-1455"},{"orcid":"0000-0001-6220-2052","full_name":"Guet, Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","last_name":"Guet","first_name":"Calin C"}],"keyword":["single cell microscopy","mother machine microfluidic device","AcrAB-TolC pump","multi-drug efflux","Escherichia coli"],"abstract":[{"text":"This repository contains the data collected for the manuscript \"Biased partitioning of the multi-drug efflux pump AcrAB-TolC underlies long-lived phenotypic heterogeneity\".\r\nThe data is compressed into a single archive.

Mother cells inheriting old poles are phenotypically distinct and display increased drug efflux activity relative to daughters. Consequently, we find systematic and long-lived growth differences between mother and daughter cells in the presence of subinhibitory drug concentrations. A simple model for biased partitioning predicts a population structure of long-lived and highly heterogeneous phenotypes. This straightforward mechanism of generating sustained growth rate differences at subinhibitory antibiotic concentrations has implications for understanding the emergence of multidrug resistance in bacteria."}],"corr_author":"1","day":"21","title":"Biased partitioning of the multidrug efflux pump AcrAB TolC underlies long lived phenotypic heterogeneity","volume":356,"year":"2017","doi":"10.1126/science.aaf4762","publication_status":"published"}]
