When expressed in cultured cells, SipB caused the formation of and localized to unusual multimembrane structures. These structures resembled autophagosomes and contained both mitochondrial and endoplasmic reticulum markers. A mutant form of SipB devoid of membrane fusion activity localized to mitochondria, but did not induce the formation of membrane structures. Upon Salmonella infection of macrophages, SipB was found in mitochondria, which appeared swollen and devoid of christae. Salmonella-infected macrophages exhibited marked accumulation of autophagic vesicles. We propose that Salmonella, through the action of SipB, kills macrophages by disrupting mitochondria, thereby inducing autophagy and cell death.<\/jats:p>","DOI":"10.1083\/jcb.200309161","type":"journal-article","created":{"date-parts":[[2003,12,8]],"date-time":"2003-12-08T15:07:51Z","timestamp":1070896071000},"page":"1123-1131","update-policy":"https:\/\/doi.org\/10.1083\/jcb.crossmarkpolicy","source":"Crossref","is-referenced-by-count":189,"title":["A\n                    <i>Salmonella<\/i>\n                    protein causes macrophage cell death by inducing autophagy"],"prefix":"10.1083","volume":"163","author":[{"given":"Lorraine D.","family":"Hernandez","sequence":"first","affiliation":[{"name":"1Section of Microbial Pathogenesis, Yale University School of Medicine, New Haven, CT 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Pypaert","sequence":"additional","affiliation":[{"name":"2Department of Cell Biology, Yale University School of Medicine, New Haven, CT 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard A.","family":"Flavell","sequence":"additional","affiliation":[{"name":"3Section of Immunobiology and the Howard Hughes Medical Institute, Yale University School of Medicine, New Haven, CT 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge E.","family":"Gala\u0301n","sequence":"additional","affiliation":[{"name":"1Section of Microbial Pathogenesis, Yale University School of Medicine, New Haven, CT 06510"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[2003,12,8]]},"reference":[{"key":"2023072214422385600_BIB1","first-page":"3","volume":"66","year":"1995","journal-title":"Eur.
