Deubiquitinase USP37 enhances the anti-HIV-2/SIV ability of the host restriction factor SAMHD1.

The Vpx protein encoded by HIV-2/simian immunodeficiency virus (SIV) can antagonize the restriction of the host intrinsic restriction factor, SAMHD1, in nondividing cells by promoting its polyubiquitination and subsequent degradation, thereby facilitating viral replication and immune evasion. However, the role of deubiquitinating enzymes (DUBs) in the dynamics of virus and host remains poorly understood. Here, we demonstrate that DUB USP37 significantly reverses the Vpx-mediated degradation of SAMHD1 in various HIV-2/SIV subtypes by interacting with SAMHD1 and removing its ubiquitin chains.

Dietary niacin supplementation improves meat quality, muscle fiber type, and mitochondrial function in heat-stressed Taihe black-bone silky fowls.

Background: A recent study has shown that niacin supplementation induces the conversion of type II to type I muscle fibres, thereby promoting a phenotypic shift in oxidative metabolism in porcine skeletal muscle. These effects may be mediated by modulation of the AMPK1/SIRT1 pathway, which activates peroxisome proliferator-activated receptor coactivator-1α (PGC-1α), a key regulator of fibre conversion, thereby promoting skeletal muscle mitochondrial biogenesis and myofibre conversion. In this study, we explored how niacin (NA) supplementation impacts the quality of meat and the characteristics of muscle fibers in Taihe Black-bone Silky Fowls (TBsf) exposed to heat conditions.

Finite Element Analysis of Electrostatic Coupling in LISA Pathfinder Inertial Sensors.

In the LISA Pathfinder (LPF) mission, electrostatic noise can reach the femto-Newtonian level despite the fact that the LPF's sensors are equipped with potential shielding. Most of the existing simulation studies focus on the electrostatic edge effect and related fields, while the simulation study of the patch effect is neglected. For that reason, this paper analyzes the basic principle of electrostatic noise and constructs a simulation model for studying the coupling effects of a TM's residual charge and stray bias voltage.

RPLP1 restricts HIV-1 transcription by disrupting C/EBPβ binding to the LTR.

Long-term non-progressors (LTNPs) of HIV-1 infection may provide important insights into mechanisms involved in viral control and pathogenesis. Here, our results suggest that the ribosomal protein lateral stalk subunit P1 (RPLP1) is expressed at higher levels in LTNPs compared to regular progressors (RPs). Functionally, RPLP1 inhibits transcription of clade B HIV-1 strains by occupying the C/EBPβ binding sites in the viral long terminal repeat (LTR).

Cellular senescence, DNA damage, and neuroinflammation in the aging brain.

Aging may lead to low-level chronic inflammation that increases the susceptibility to age-related conditions, including memory impairment and progressive loss of brain volume. As brain health is essential to promoting healthspan and lifespan, it is vital to understand age-related changes in the immune system and central nervous system (CNS) that drive normal brain aging. However, the relative importance, mechanistic interrelationships, and hierarchical order of such changes and their impact on normal brain aging remain to be clarified.
