[HTML][HTML] A de novo approach to inferring within-host fitness effects during untreated HIV-1 infection

CJR Illingworth, J Raghwani, D Serwadda… - PLoS …, 2020 - journals.plos.org
In the absence of effective antiviral therapy, HIV-1 evolves in response to the within-host
environment, of which the immune system is an important aspect. During the earliest stages …

[HTML][HTML] A binary trait model reveals the fitness effects of HIV-1 escape from T cell responses

Y Gao, JP Barton - bioRxiv, 2024 - ncbi.nlm.nih.gov
Natural selection often acts on multiple traits simultaneously. For example, the virus HIV-1
faces pressure to evade host immunity while also preserving replicative fitness. While past …

Fitness costs and diversity of the cytotoxic T lymphocyte (CTL) response determine the rate of CTL escape during acute and chronic phases of HIV infection

VV Ganusov, N Goonetilleke, MKP Liu… - Journal of …, 2011 - Am Soc Microbiol
ABSTRACT HIV-1 often evades cytotoxic T cell (CTL) responses by generating variants that
are not recognized by CTLs. We used single-genome amplification and sequencing of …

Resolving genetic linkage reveals patterns of selection in HIV-1 evolution

MS Sohail, RHY Louie, MR McKay, JP Barton - bioRxiv, 2019 - biorxiv.org
Identifying the genetic drivers of adaptation is a necessary step in understanding the
dynamics of rapidly evolving pathogens and cancer. However, signals of selection are …

[HTML][HTML] Relative rate and location of intra-host HIV evolution to evade cellular immunity are predictable

JP Barton, N Goonetilleke, TC Butler, BD Walker… - Nature …, 2016 - nature.com
Human immunodeficiency virus (HIV) evolves within infected persons to escape being
destroyed by the host immune system, thereby preventing effective immune control of …

Immune-mediated positive selection drives human immunodeficiency virus type 1 molecular variation and predicts disease duration

HA Ross, AG Rodrigo - Journal of virology, 2002 - Am Soc Microbiol
Using likelihood-based evolutionary methods, we demonstrate that the broad genetic
diversity of human immunodeficiency virus type 1 (HIV-1) in an infected individual is a …

Evolution during primary HIV infection does not require adaptive immune selection

DA Swan, M Rolland, JT Herbeck… - Proceedings of the …, 2022 - National Acad Sciences
Modern HIV research depends crucially on both viral sequencing and population
measurements. To directly link mechanistic biological processes and evolutionary dynamics …

[HTML][HTML] Convergent evolution as an indicator for selection during acute HIV-1 infection

F Bertels, KJ Metzner… - Peer Community …, 2021 - peercommunityjournal.org
Convergent evolution describes the process of di erent populations acquiring similar
phenotypes or genotypes. Complex organisms with large genomes only rarely and only …

Stochastic effects are important in intrahost HIV evolution even when viral loads are high

EL Read, AA Tovo-Dwyer… - Proceedings of the …, 2012 - National Acad Sciences
Blood plasma viral loads and the time to progress to AIDS differ widely among untreated HIV-
infected humans. Although people with certain HLA (HLA-I) alleles are more likely to control …

Fitness-balanced escape determines resolution of dynamic founder virus escape processes in HIV-1 infection

JE Sunshine, BB Larsen, B Maust, E Casey… - Journal of …, 2015 - Am Soc Microbiol
To understand the interplay between host cytotoxic T-lymphocyte (CTL) responses and the
mechanisms by which HIV-1 evades them, we studied viral evolutionary patterns associated …
