Protease‐mediated maturation of M‐PMV reverse transcriptase into a functional heterodimer

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Reverse transcriptase (RT) of retroviruses orchestrates viral replication, yet its structural diversity remains poorly understood. Well‐studied RTs, such as those from HIV‐1, murine leukemia virus, and avian myeloblastosis virus, were characterized decades ago, but less prominent retroviruses have escaped detailed analysis.

Insights into the Functions of a Prophage Recombination Directionality Factor

Viruses, 2012
Recombination directionality factors (RDFs), or excisionases, are essential players of prophage excisive recombination. Despite the essentially catalytic role of the integrase in both integrative and excisive recombination, RDFs are required to direct ...

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

The Factors Involved in Plant–Insect–Microbe Interactions Expanded: Genome Analysis and Description of Frigoribacterium adelgis sp. nov.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Aerobic Actinobacteria belonging to the genus Frigoribacterium were isolated from adelgid Adelges (Aphrastasia) pectinatae collected from a Korean fir tree. Genomic analysis showed that these bacteria encode a range of factors that may be involved in the interactions between Frigoribacterium strains, adelgids and/or Korean fir trees.

Penile vascular status in young men living with HIV experiencing erectile dysfunction: A comparative cross‐sectional pilot study

Andrology, Volume 14, Issue 2, Page 377-384, February 2026.
Abstract Background Erectile dysfunction in people living with HIV is a multifactorial disease, but the role of penile vascular status assessed by dynamic penile color Doppler echography is underexplored. Objectives This study assessed penile vascular status in young males living with HIV experiencing erectile dysfunction, comparing them to HIV ...

Comparison Between Several Integrase-defective Lentiviral Vectors Reveals Increased Integration of an HIV Vector Bearing a D167H Mutant

Molecular Therapy: Nucleic Acids, 2014
HIV-1 derived vectors are among the most efficient for gene transduction in mammalian tissues. As the parent virus, they carry out vector genome insertion into the host cell chromatin.

White–Sutton Syndrome: Insight of an Italian Cohort of 19 Subjects

Clinical Genetics, Volume 109, Issue 2, Page 335-340, February 2026.
New insights into White–Sutton syndrome with a collection of 19 Italian patients. Due to its complexity, we stress the importance of a systematic evaluation following the diagnosis and a thoughtful management of patients. Preliminary genotype–phenotype correlation analysis suggests the association between disruptive splicing variants and more severe ...

Efavirenz and CYP2C9 Genetic Polymorphisms Reduce CYP2C9 Activity in Healthy Participants

Clinical and Translational Science, Volume 19, Issue 2, February 2026.
ABSTRACT Efavirenz's effects on cytochrome P450 2C9 (CYP2C9) activity have not been formally characterized in vivo. We conducted the first clinical drug–drug interaction (DDI) study to test the effect of chronic efavirenz dosing on CYP2C9 activity, using tolbutamide as a selective probe.
