Journal ArticleDOI
Sexual transmission and propagation of SIV and HIV in resting and activated CD4+ T cells.
Zhiqiang Zhang,T. Schuler,Mary Zupancic,Stephen W. Wietgrefe,Katherine Staskus,Keith A. Reimann,Todd A. Reinhart,Michael J. Rogan,Winston Cavert,Christopher J. Miller,Ronald S. Veazey,Daan W. Notermans,Susan J. Little,Sven A. Danner,Douglas D. Richman,Douglas D. Richman,Diane V. Havlir,Joseph K. Wong,Joseph K. Wong,H. L. Jordan,Timothy W. Schacker,Paul Racz,Klara Tenner-Racz,Norman L. Letvin,Steven M. Wolinsky,Ashley T. Haase +25 more
TL;DR: Both viruses were found to replicate predominantly in CD4(+) T cells at the portal of entry and in lymphoid tissues, and infection was propagated not only in activated and proliferating T cells but also, surprisingly, in resting T cells.
Journal ArticleDOI
Kinetics of response in lymphoid tissues to antiretroviral therapy of HIV-1 infection
Winston Cavert,Daan W. Notermans,Katherine Staskus,Stephen W. Wietgrefe,Mary Zupancic,Kristin Gebhard,Keith Henry,Zhiqiang Zhang,Roger Mills,Hugh McDade,Jaap Goudsmit,Sven A. Danner,Ashley T. Haase +12 more
TL;DR: In lymphoid tissue, where human immunodeficiency virus-type 1 (HIV-1) is produced and stored, three-drug treatment with viral protease and reverse transcriptase inhibitors markedly reduced viral burden as mentioned in this paper.
Journal ArticleDOI
Persistent HIV-1 replication is associated with lower antiretroviral drug concentrations in lymphatic tissues
Courtney V. Fletcher,Kathryn Staskus,Stephen W. Wietgrefe,Meghan K Rothenberger,Cavan S. Reilly,Jeffrey G. Chipman,Greg J. Beilman,Alexander Khoruts,Ann Thorkelson,Thomas E. Schmidt,Jodi Anderson,Katherine Perkey,Mario Stevenson,Alan S. Perelson,Daniel C. Douek,Ashley T. Haase,Timothy W. Schacker +16 more
TL;DR: The evidence of persistent replication associated with apparently suboptimal drug concentrations argues for development and evaluation of novel therapeutic strategies that will fully suppress viral replication in lymphatic tissues to avert the long-term clinical consequences of chronic immune activation driven directly or indirectly by low-level viral replication to thereby improve immune reconstitution.
Journal ArticleDOI
Propagation and Dissemination of Infection after Vaginal Transmission of Simian Immunodeficiency Virus
Christopher J. Miller,Qingsheng Li,Kristina Abel,Eun Young Kim,Zhong-Min Ma,Stephen W. Wietgrefe,Lisa La Franco-Scheuch,Lara Compton,Lijie Duan,Marta Dykhuizen Shore,Mary Zupancic,Marc Busch,John V. Carlis,Steven Wolinksy,Ashley T. Haase +14 more
TL;DR: It is shown that the mucosal barrier greatly limits the infection of cervicovaginal tissues, and thus the initial founder populations of infected cells are small, and that continuous seeding from an expanding source of production at the portal of entry is likely critical for the later establishment of a productive infection throughout the systemic LTs.
Journal ArticleDOI
Defining total-body AIDS-virus burden with implications for curative strategies
Jacob D. Estes,Cissy Kityo,Francis Ssali,Louise A. Swainson,Krystelle Nganou Makamdop,Gregory Q. Del Prete,Steven G. Deeks,Paul A. Luciw,Jeffrey G. Chipman,Gregory J. Beilman,Torfi Hoskuldsson,Alexander Khoruts,Jodi Anderson,Claire Deleage,Jacob Jasurda,Thomas E. Schmidt,Michael Hafertepe,Samuel P. Callisto,Hope Pearson,Thomas Reimann,Jared Schuster,Jordan Schoephoerster,Peter J. Southern,Katherine Perkey,Liang Shang,Stephen W. Wietgrefe,Courtney V. Fletcher,Jeffrey D. Lifson,Daniel C. Douek,Joseph M. McCune,Ashley T. Haase,Timothy W. Schacker +31 more
TL;DR: The estimated size of the residual tissue burden of 108 vDNA+ cells potentially containing replication-competent proviruses, along with evidence of continuing virus production in LT despite ART, indicated two important sources for rebound following treatment interruption.
