Meteorin-like protein alleviates intervertebral disc degeneration by suppressing lipid accumulation in nucleus pulposus cells via PPARα-CPT1A activation.

Disturbances in lipid metabolism are closely related to intervertebral disc degeneration (IDD). However, the lipid metabolism characteristics of nucleus pulposus (NP) cells during IDD are unclear. Exercise protects against IDD and acts as a potent mediator of organ metabolism, in which muscle-secreted myokines actively participate.

Gray Matter Reserve Modulates the Association between Glymphatic System Function and Cognition in Patients with Type 2 Diabetes Mellitus.

Introduction: The glymphatic system is regarded as a key factor in the pathogenesis of neurodegenerative diseases. Given the heightened risk of cognitive impairment in patients with type 2 diabetes mellitus (T2DM), the possible alterations in the glymphatic system in T2DM patients remain to be explored. Diffusion tensor imaging (DTI) analysis along the perivascular space (ALPS) index can be utilized to model the glymphatic system in humans.

The Naturally Occurring Amino Acid Substitution in the VPg α1-α2 Loop Breaks eIF4E-Mediated Resistance to PRSV by Enabling VPg to Re-Hijack Another eIF4E Isoform eIF(iso)4E in Watermelon.

Plant resistance, which acts as a selective pressure that affects viral population fitness, leads to the emergence of resistance-breaking virus strains. Most recessive resistance to potyviruses is related to the mutation of eukaryotic translation initiation factor 4E (eIF4E) or its isoforms that break their interactions with the viral genome-linked protein (VPg). In this study, we found that the VPg α1-α2 loop, which is essential for binding eIF4E, is the most variable domain of papaya ringspot virus (PRSV) VPg.

Turn Hood into Good: Recycling Silicon from Mesoporous Silica Nanoparticles through Magnesium Modification to Lower Toxicity and Promote Tissue Regeneration.

Mesoporous silica nanoparticles (MSNs) have gained wide application as excellent carrier materials; however, their limited degradation in the biological system and potential chronic toxicity pose challenges to their clinical applications. Previous studies have focused on optimizing the elimination performance of MSNs; interestingly, silicon has been well-documented as an essential body component. Therefore, converting MSNs into a form readily utilizable by the organism is a way to turn waste into a valuable resource.

Pro-inflammatory NK-like T cells are expanded in the blood and inflamed intestine in Crohn's disease.

Altered intestinal immune homeostasis leads to chronic inflammation in Crohn's disease (CD). To address disease- and tissue-specific alterations, we performed a T cell-centric mass cytometry analysis of peripheral and intestinal lymphocytes from patients with CD and healthy donors' PBMCs. Chronic intestinal inflammation enforced activation, exhaustion, and terminal differentiation of CD4 and CD8 T cells and a relative enrichment of CD4 regulatory T (Treg) cells.

Eicosapentaenoic acid induces macrophage Mox polarization to prevent diabetic cardiomyopathy.

Diabetic cardiomyopathy (DC) leads to heart failure, with few effective approaches for its intervention. Eicosapentaenoic acid (EPA) is an essential nutrient that benefits the cardiovascular system, but its effect on DC remains unknown. Here, we report that EPA protects against DC in streptozotocin and high-fat diet-induced diabetic mice, with an emphasis on the reduction of cardiac M1-polarized macrophages.

Cardamonin protects against diabetic cardiomyopathy by activating macrophage NRF2 signaling through molecular interaction with KEAP1.

Diabetic cardiomyopathy (DCM) contributes to a large proportion of heart failure incidents in the diabetic population, but effective therapeutic approaches are rare. Cardamonin (CAD), a flavonoid found in , possesses anti-inflammatory and anti-oxidative activities. Here we report a profound protective effect of CAD on DCM in a mouse model of type 2 diabetes induced by streptozotocin and a high-fat diet, in which gavage with CAD improved hyperglycemia and glucose intolerance and mitigated diabetic cardiac injuries including cardiac dysfunction, hypertrophy, apoptotic cell death and infiltration of inflammatory cells, especially M1 polarized macrophages.

A low-kiloelectronvolt focused ion beam strategy for processing low-thermal-conductance materials with nanoampere currents.

Ion beam-induced heat damage in thermally low conductive specimens such as biological samples is gaining increased interest within the scientific community. This is partly due to the increased use of FIB-SEMs in biology as well as the development of complex materials, such as polymers, which need to be analyzed. The work presented here looks at the physics behind the ion beam-sample interactions and the effect of the incident ion energy (set by the acceleration voltage) on inducing increases in sample temperature and potential heat damage in thermally low conductive materials such as polymers and biological samples.

An Integrated All-Natural Conductive Supramolecular Hydrogel Wearable Biosensor with Enhanced Biocompatibility and Antibacterial Properties.

Unveiling the governing role of 'remodeling triangle area' in soft-hard tissue interface equilibrium for metal implants advancement.

Metal implants holds significant promise for diverse fixed prostheses. However, their long-term reliability and broader application are hindered by challenges related to the disequilibrium at the soft-hard tissue interface. By using anti-inflammatory (PDA/IL4) and pro-inflammatory (PDA/LPS/IFNγ) coatings to modulate distinct immune characteristics, we discovered a dynamic bioactive structure at the soft-hard tissue interface around metal implant, which we have named the 'Remodeling Triangle Area' (RTA).

Plasmopara viticola effector PvCRN20 represses the import of VvDEG5 into chloroplasts to suppress immunity in grapevine.

Chloroplasts play a crucial role in plant defense against pathogens, making them primary targets for pathogen effectors that suppress host immunity. This study characterizes the Plasmopara viticola CRN-like effector, PvCRN20, which interacts with DEG5 in the cytoplasm but not with its interacting protein, DEG8, which is located in the chloroplast. By transiently overexpressing in tobacco leaves, we show that PvCRN20 could inhibit INF1- and Bax-triggered cell death.

This study examined the penetration and accumulation patterns of polystyrene nanoplastics (PS-NPs) in different cell types within rice roots, and explored how the roots quickly modify their cell wall structure in response.

Oligoclonal CD4CXCR5 T cells with a cytotoxic phenotype appear in tonsils and blood.

In clinical situations, peripheral blood accessible CD3CD4CXCR5 T-follicular helper (T) cells may have to serve as a surrogate indicator for dysregulated germinal center responses in tissues. To determine the heterogeneity of T cells in peripheral blood versus tonsils, CD3CD4CD45RACXCR5 cells of both origins were sorted. Transcriptomes, TCR repertoires and cell-surface protein expression were analysed by single-cell RNA sequencing, flow cytometry and immunohistochemistry.

Inclusion Strategy for Constructing S/N Orbital Hybridization-Regulated sp/sp Carbon toward Boost Electrocatalysis.

Metal-free carbon-based electrocatalysts have gained significant attention in the field of zinc-air batteries (ZABs) due to their affordability, good conductivity and chemical stability.
