The Competitive Interplay between Allosteric HIV-1 Integrase Inhibitor BI/D and LEDGF/p75 during the Early Stage of HIV-1 Replication Adversely Affects Inhibitor Potency.

ACS Chemical Biology, 2016
Allosteric HIV-1 integrase inhibitors (ALLINIs) have recently emerged as a promising class of antiretroviral agents and are currently in clinical trials. In infected cells, ALLINIs potently inhibit viral replication by impairing virus particle maturation

The road less taken: Dihydroflavonol 4‐reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation

Molecular Ecology, EarlyView.
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...

Comprehensive Analysis of HIV-1 Integrase Resistance-Related Mutations in African Countries

Pathogens
The growing emergence of non-nucleoside reverse transcriptase inhibitor (NNRTI) HIV drug resistance in sub-Saharan Africa (SSA) led to the World Health Organization (WHO) recommending, in 2018, a transition to dolutegravir (DTG) as a first-line ...

Recombination directionality factor gp3 binds ϕC31 integrase via the zinc domain, potentially affecting the trajectory of the coiled-coil motif

Nucleic Acids Research, 2017
To establish a prophage state, the genomic DNA of temperate bacteriophages normally becomes integrated into the genome of their host bacterium by integrase-mediated, site-specific DNA recombination.

Evidence for a Role of Extraintestinal Pathogenic Escherichia coli, Enterococcus faecalis and Streptococcus gallolyticus in the Aetiology of Exudative Cloacitis in the Critically Endangered Kākāpō (Strigops habroptilus)

Molecular Ecology, EarlyView.
ABSTRACT The kākāpō is a critically endangered flightless parrot which suffers from exudative cloacitis, a debilitating disease resulting in inflammation of the vent margin or cloaca. Despite this disease emerging over 20 years ago, the cause of exudative cloacitis remains elusive.

Reversibility of Neuropsychiatric Adverse Events after Switching to Darunavir/Cobicistat or Doravirine in Men on INSTI-Based Regimen

Viruses
Integrase strand transfer inhibitors (INSTI) are associated with neuropsychiatric adverse events (NPAEs). The aim of this study was to evaluate improvements in NPAEs after switching an INSTI-based regimen to darunavir/cobicistat (DRV/c) or doravirine ...

Drug resistance emergence in macaques administered cabotegravir long-acting for pre-exposure prophylaxis during acute SHIV infection

Nature Communications, 2019
Long-acting formulation of the integrase inhibitor cabotegravir (CAB LA) is in clinical development for HIV pre-exposure prophylaxis (PrEP). Here, using a SHIV macaque model, the authors show emergence of integrase mutations associated to CAB LA PrEP ...

A long-acting integrase inhibitor protects female macaques from repeated high-dose intravaginal SHIV challenge

Science Translational Medicine, 2015
The long-acting integrase inhibitor GSK744 protects macaques from three high-dose SHIV challenges at plasma drug concentrations that could be achieved with quarterly injections in humans. Taking a Shot at HIV HIV-1 transmission during vaginal intercourse

Structural Insights on Retroviral DNA Integration: Learning from Foamy Viruses

Viruses, 2019
Foamy viruses (FV) are retroviruses belonging to the Spumaretrovirinae subfamily. They are non-pathogenic viruses endemic in several mammalian hosts like non-human primates, felines, bovines, and equines.

HIV Dynamics and Integrase Inhibitors

Antiviral Chemistry and Chemotherapy, 2009
The integrase inhibitor (INI) raltegravir has shown promising results in clinical trials to date, reducing second phase HIV RNA levels by 70% in comparison with standard regimens. These trial results have been limited by the 50 copies/ml detection limit of the HIV RNA assay and have not investigated the effect of an INI regimen on levels of latently ...
