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
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.
Journal ArticleDOI
Large number of rebounding/founder HIV variants emerge from multifocal infection in lymphatic tissues after treatment interruption
Meghan K Rothenberger,Brandon F. Keele,Stephen W. Wietgrefe,Courtney V. Fletcher,Gregory J. Beilman,Jeffrey G. Chipman,Alexander Khoruts,Jacob D. Estes,Jodi Anderson,Samuel P. Callisto,Thomas E. Schmidt,Ann Thorkelson,Cavan S. Reilly,Katherine Perkey,Thomas Reimann,Netanya S. Utay,Krystelle Nganou Makamdop,Mario Stevenson,Daniel C. Douek,Ashley T. Haase,Timothy W. Schacker +20 more
TL;DR: Recrudescent infection was detectable in multiple different LTs, and the population was genetically diverse, consistent with reactivation from a larger number of cells, underscore the challenges facing strategies to eradicate HIV infection.
Journal ArticleDOI
Defining HIV and SIV Reservoirs in Lymphoid Tissues.
Claire Deleage,Stephen W. Wietgrefe,Gregory Q. Del Prete,David R. Morcock,Xing Pei Hao,Michael Piatak,Julian W. Bess,Jodi Anderson,Katherine Perkey,Cavan S. Reilly,Joseph M. McCune,Ashley T. Haase,Jeffrey D. Lifson,Timothy W. Schacker,Jacob D. Estes +14 more
TL;DR: Analysis of LT samples from macaques prior to and during combination antiretroviral therapy demonstrated that B cell follicles are an important anatomical compartment for both latent and active viral persistence during treatment, and developed a specific and sensitive next-generation in situ hybridization approach to detect vRNA.
Journal ArticleDOI
Targeted cytotoxic therapy kills persisting HIV infected cells during ART.
Paul W. Denton,Julie M. Long,Stephen W. Wietgrefe,Craig Sykes,Rae Ann Spagnuolo,Olivia D. Snyder,Katherine Perkey,Nancie M. Archin,Shailesh K. Choudhary,Kuo Yang,Michael G. Hudgens,Ira Pastan,Ashley T. Haase,Angela D. M. Kashuba,Edward A. Berger,David M. Margolis,J. Victor Garcia +16 more
TL;DR: The in vivo efficacy of a targeted cytotoxic therapy to kill infected cells that persist despite long-term ART is determined and it is found that compared to ART alone, this agent profoundly depleted productively infected cells systemically.
