Virus entry by macropinocytosis.
Mercer J, Helenius A. Mercer J, et al. Nat Cell Biol. 2009 May;11(5):510-20. doi: 10.1038/ncb0509-510. Nat Cell Biol. 2009. PMID: 19404330 Review.
Role of DC-SIGN in Lassa virus entry into human dendritic cells.
Goncalves AR, Moraz ML, Pasquato A, Helenius A, Lozach PY, Kunz S. Goncalves AR, et al. J Virol. 2013 Nov;87(21):11504-15. doi: 10.1128/JVI.01893-13. Epub 2013 Aug 21. J Virol. 2013. PMID: 23966408 Free PMC article.
The arenavirus Lassa virus (LASV) causes a severe hemorrhagic fever with high mortality in humans. Antigen-presenting cells, in particular dendritic cells (DCs), are early and preferred targets of LASV, and their productive infection contributes to the virus-induced immuno …

Host cell factors and functions involved in vesicular stomatitis virus entry.
Johannsdottir HK, Mancini R, Kartenbeck J, Amato L, Helenius A. Johannsdottir HK, et al. J Virol. 2009 Jan;83(1):440-53. doi: 10.1128/JVI.01864-08. Epub 2008 Oct 29. J Virol. 2009. PMID: 18971266 Free PMC article.
We found that endocytosis of VSV was a fast process with a half time of 2.5 to 3 min and that acid activation occurred within 1 to 2 min after internalization in early endosomes. ...Thus, VSV can induce productive internalization by exploiting a specific comb …

Virus entry at a glance.
Yamauchi Y, Helenius A. Yamauchi Y, et al. J Cell Sci. 2013 Mar 15;126(Pt 6):1289-95. doi: 10.1242/jcs.119685. Epub 2013 May 2. J Cell Sci. 2013. PMID: 23641066 Review. No abstract available.
Membranes, viruses, detergents, and endosomes.
Helenius A. Helenius A. Mol Biol Cell. 2012 Nov;23(21):4157-9. doi: 10.1091/mbc.E12-05-0383. Mol Biol Cell. 2012. PMID: 23112226 Free PMC article.
Late-penetrating viruses.
Lozach PY, Huotari J, Helenius A. Lozach PY, et al. Curr Opin Virol. 2011 Jul;1(1):35-43. doi: 10.1016/j.coviro.2011.05.004. Epub 2011 Jun 12. Curr Opin Virol. 2011. PMID: 22440565 Review.
The late timing is generally determined by a low pH-threshold for the acid-activated penetration process (pH 6.2-4.9), but there can be a combination of other reasons for a delay. ...

Caveolin-1 is ubiquitinated and targeted to intralumenal vesicles in endolysosomes for degradation.
Hayer A, Stoeber M, Ritz D, Engel S, Meyer HH, Helenius A. Hayer A, et al. J Cell Biol. 2010 Nov 1;191(3):615-29. doi: 10.1083/jcb.201003086. J Cell Biol. 2010. PMID: 21041450 Free PMC article.
We studied the degradation of caveolin-1 (CAV1), a major caveolar protein, in CV1 cells. CAV1 was degraded very slowly, but turnover could be accelerated by compromising caveolae assembly. ...The findings led us to a revised model for endocytic trafficking of CAV1.. …

Virus entry by endocytosis.
Mercer J, Schelhaas M, Helenius A. Mercer J, et al. Annu Rev Biochem. 2010;79:803-33. doi: 10.1146/annurev-biochem-060208-104626. Annu Rev Biochem. 2010. PMID: 20196649 Review.
Merely to gain entry, animal viruses make use of a repertoire of cellular processes that involve hundreds of cellular proteins. ...The internalization may involve clathrin-mediated endocytosis (CME), macropinocytosis, caveolar/lipid raft-mediated endocytosis, or a v …
