HIV-1 nef suppression by virally encoded microRNA

open access: yesRetrovirology, 2004
Background MicroRNAs (miRNAs) are 21~25-nucleotides (nt) long and interact with mRNAs to trigger either translational repression or RNA cleavage through RNA interference (RNAi), depending on the degree of complementarity with the target mRNAs. Our recent

Sleep characteristics and self‐reported sleep quality in the oldest‐old: Results from a prospective longitudinal cohort study

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Little is known about the correlation between subjective perception and objective measures of sleep quality in particular in the oldest‐old. The aim of this study was to perform longitudinal home sleep monitoring in this age group, and to correlate results with self‐reported sleep quality.

Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis.

Solution Synthesis of Actinide Chalcogenide and Oxychalcogenide Nanoparticles

open access: yesAngewandte Chemie, Volume 138, Issue 36, 1 September 2026.
We report the synthesis of UOS, UOSe, and US2 nanoparticles under colloidal conditions. The magnetic properties were measured of all three materials and compared to prior studies of UO2 nanoparticles. Nanoparticle phases were determined using powder diffraction, and size by transmission electron microscopy.

LncRNA-NEF is downregulated in postmenopausal osteoporosis and is related to course of treatment and recurrence

open access: yesJournal of International Medical Research, 2019
Objectives We investigated the role of long non-coding (lnc) RNA-NEF (neighboring enhancer of FoxA2), a characterized oncogene in cancer biology, in postmenopausal osteoporosis and its diagnostic and prognostic value in this disease.

Relative Resistance of HLA-B to Downregulation by Naturally Occurring HIV-1 Nef Sequences

open access: yesmBio, 2016
HIV-1 Nef binds to the cytoplasmic region of HLA-A and HLA-B and downregulates these molecules from the surface of virus-infected cells, thus evading immune detection by CD8+ T cells.

ARF1 Regulates Nef-Induced CD4 Degradation [PDF]

open access: yes, 2004
Background: The HIV Nef protein downregulates CD4 through sequential connection with clathrin-coated pits and the COP1 coatomer, resulting in accelerated endocytosis and lysosomal targeting.Results: Here we report that the small GTPase ARF1 controls the ...

The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

HIV-1 Nef binds the DOCK2-ELMO1 complex to activate rac and inhibit lymphocyte chemotaxis.

open access: yesPLoS Biology, 2004
The infectious cycle of primate lentiviruses is intimately linked to interactions between cells of the immune system. Nef, a potent virulence factor, alters cellular environments to increase lentiviral replication in the host, yet the mechanisms ...
