Endosomal escape also helps viruses bypass endolysosomal degradation and presentation to certain Toll-like intrinsic immunity receptors. The mechanisms for cytosolic delivery of nonenveloped viruses or nucleocapsids from enveloped viruses are poorly understood, in part because no quantitative assays are readily available which directly measure the penetration of viruses into the cytosol. Following uptake by clathrin-mediated endocytosis or macropinocytosis, the nonenveloped adenoviruses penetrate from endosomes to the cytosol, and they traffic with cellular motors on microtubules to the nucleus for replication. In this report, we present a novel single-cell imaging assay which quantitatively measures individual cytosolic viruses and distinguishes them from endosomal viruses or viruses at the plasma membrane. Using this assay, we showed that the penetration of human adenoviruses of the species C and B occurs rapidly after virus uptake. Efficient penetration does not require acidic pH in endosomes. This assay is versatile and can be adapted to other adenoviruses and members of other nonenveloped and enveloped virus families.<\/jats:p>","DOI":"10.1128\/jvi.01833-13","type":"journal-article","created":{"date-parts":[[2013,9,11]],"date-time":"2013-09-11T22:23:49Z","timestamp":1378938229000},"page":"12367-12379","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":78,"title":["A Direct and Versatile Assay Measuring Membrane Penetration of Adenovirus in Single Cells"],"prefix":"10.1128","volume":"87","author":[{"given":"Maarit","family":"Suomalainen","sequence":"first","affiliation":[{"name":"Institute of Molecular Life Sciences, University of Zurich, Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefania","family":"Luisoni","sequence":"additional","affiliation":[{"name":"Institute of Molecular Life Sciences, University of Zurich, Zurich, Switzerland"},{"name":"Molecular Life Sciences Graduate School, ETH and University of Zurich, Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karin","family":"Boucke","sequence":"additional","affiliation":[{"name":"Institute of Molecular Life Sciences, University of Zurich, Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Bianchi","sequence":"additional","affiliation":[{"name":"Institute of Molecular Life Sciences, University of Zurich, Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel A.","family":"Engel","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Cancer Biology, University of Virginia School of Medicine, Charlottesville, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urs F.","family":"Greber","sequence":"additional","affiliation":[{"name":"Institute of Molecular Life Sciences, University of Zurich, Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-biochem-060208-104626"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.coviro.2011.06.002"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.201108131"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tim.2013.06.001"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1186\/1743-422X-10-177"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.immuni.2013.05.007"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tim.2013.04.004"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.coviro.2011.05.002"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.coviro.2012.12.004"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.01102-12"},{"key":"e_1_3_2_12_2","first-page":"125","volume-title":"Virus taxonomy: ninth report of the International Committee on Taxonomy of Viruses","author":"Harrach B","year":"2011","unstructured":"HarrachBBenk\u00f6MBothGBrownMDavisonAEchavarr\u00edaMHessMJonesMKajonALehmkuhlHMautnerVMittalSWadellG. 2011.
