Dialysis purification of integrase-DNA complexes provides high-resolution atomic force microscopy images: dimeric recombinant HIV-1 integrase binding and specific looping on DNA. [PDF]

PLoS ONE, 2013
It remains difficult to obtain high-resolution atomic force microscopy images of HIV-1 integrase bound to DNA in a dimeric or tetrameric fashion. We therefore constructed specific target DNAs to assess HIV-1 integrase binding and purified the complex by ...

Weight gain among treatment-naïve persons with HIV starting integrase inhibitors compared to non-nucleoside reverse transcriptase inhibitors or protease inhibitors in a large observational cohort in the United States and Canada. [PDF]

, 2020
IntroductionWeight gain following antiretroviral therapy (ART) initiation is common, potentially predisposing some persons with HIV (PWH) to cardio-metabolic disease.

Peptide HIV-1 Integrase Inhibitors from HIV-1 Gene Products [PDF]

Journal of Medicinal Chemistry, 2010
Anti-HIV peptides with inhibitory activity against HIV-1 integrase (IN) have been found in overlapping peptide libraries derived from HIV-1 gene products. In a strand transfer assay using IN, inhibitory active peptides with certain sequential motifs related to Vpr- and Env-derived peptides were found.

Three main mutational pathways in HIV-2 lead to high-level raltegravir and elvitegravir resistance: implications for emerging HIV-2 treatment regimens. [PDF]

PLoS ONE, 2012
Human immunodeficiency virus type 2 (HIV-2) is intrinsically resistant to non-nucleoside reverse transcriptase inhibitors and exhibits reduced susceptibility to several of the protease inhibitors used for antiretroviral therapy of HIV-1. Thus, there is a

Integrase residues that determine nucleotide preferences at sites of HIV-1 integration: implications for the mechanism of target DNA binding [PDF]

, 2014
Retroviruses favor target-DNA (tDNA) distortion and particular bases at sites of integration, but the mechanism underlying HIV-1 selectivity is unknown. Crystal structures revealed a network of prototype foamy virus (PFV) integrase residues that distort ...

Resistance to inhibitors of the human immunodeficiency virus type 1 integration

Brazilian Journal of Infectious Diseases, 2010
This review will summarize the role of integrase in HIV-1 infection, the mechanism of integrase inhibitors and resistance with an emphasis on raltegravir (RAL), the first integrase inhibitor licensed to treat HIV-1 infection.

Reversal of Epigenetic Silencing Allows Robust HIV-1 Replication in the Absence of Integrase Function

mBio, 2020
Integration of the proviral DNA intermediate into the host cell genome normally represents an essential step in the retroviral life cycle. While the reason(s) for this requirement remains unclear, it is known that unintegrated proviral DNA is ...

Emergence of the G118R Pan-Integrase Resistance Mutation as a Result of Low Compliance to a Dolutegravir-Based cART

Infectious Disease Reports, 2022
HIV-1 resistance towards integrase inhibitors is a potential threat of the success of HIV-1 combination treatment. G118R is a rare drug resistance mutation conferring pan-integrase resistance.

Modeling the HIV-1 Intasome: A Prototype View of the Target of Integrase Inhibitors

Viruses, 2010
The HIV-1 integrase enzyme is essential for integrating the viral DNA into the host chromosome. Infection is aborted in the absence of integration, making integrase an attractive antiviral target. Recently approved inhibitors of integrase bind tightly to

Detection of HIV-1 infection in dried blood spots from a 12-year-old ABO bedside test card [PDF]

, 1998
Background and Objectives: We tested dried blood from an ABO bedside test card which had been stored at room temperature for 12 years, to prove that a patient with HIV-1 infection had been infected by blood transfusion. Materials and Methods: Immunoblots
