Upregulation of CD244 promotes CD8 T cell exhaustion in patients with alveolar echinococcosis and a murine model.

Background: In patients with alveolar echinococcosis (AE), CD8 T cells undergo functional exhaustion, which accelerates the malignant progression of AE. However, the role of inhibitory receptor CD244 in mediating CD8 T cell exhaustion remains elusive.

Methods: CD244 expression on exhausted CD8 T cells in the close liver tissue (CLT) of AE patients was analyzed using single-cell RNA sequencing data.

Photothermal Induced Dual-Interface: Accelerating Sustainable Hydrogen Evolution from Formic Acid.

Formic acid (FA), a liquid hydrogen storage carrier, can release hydrogen via photothermal catalysis, providing a clean and sustainable solution toward a carbon-neutral energy cycle. Despite recent advances in the design of efficient catalysts, the development of advanced systems with high H yield, stability, and durability remains challenging due to the inefficient photothermal conversion and mass transfer in the traditional liquid-solid bulk system, as well as the trade-off between hydrogen storage density and dehydrogenation rate. Here, we address these challenges by creating a photothermal-induced dual-interface characterized by high spectral absorption and low heat loss, a facile supply of FA, and vaporization of FA to minimize the energy barrier of the reaction.

Mo Doping Induced Ni Surface Enrichment of Porous Spherical Core-Shell Bifunctional Electrocatalyst for Overall Water Splitting.

Constructing catalysts with unique structures to optimize the intrinsic activity is a promising strategy. In this work, a newly developed NiCoMo-BTC-15h catalyst consisting of Ni nanoparticles enriched on the surface along with a core-shell porous structure is prepared via a hydrothermal process.

Self-Assembled Blossom-Shaped NiCoS Nanosheets In Situ Deposited Electrodes: Possessing High Reactivity and Selectivity for Bromine-Based Flow Batteries.

Bromine-based flow batteries (Br-FBs) are emerging rapidly due to their high energy density and wide potential window for renewable energy storage systems. Nevertheless, the sluggish kinetics of the Br/Br reaction on the electrode is considered to be the main challenge contributing to the poor performance of Br-FBs. Herein, we report self-assembled blossom-shaped NiCoS nanosheets, enabling in situ growth on graphite felt (GF) via a one-step hydrothermal method.

Exploring the role of non-canonical splice site variants in aberrant splicing associated with reproductive genetic disorders.

Whole-exome sequencing (WES) is frequently utilized in diagnosing reproductive genetic disorders to identify various genetic variants. Canonical ±1,2 splice sites are typically considered highly pathogenic, while variants at the 5' or 3' ends of exon boundaries are often considered synonymous or missense variants, with their potential impact on abnormal gene splicing frequently overlooked. In this study, we identified five variants located at the last two bases of the exons and two canonical splicing variants in five distinct families affected by reproductive genetic disorders through WES.

Targeting myeloid-derived suppressor cells promotes antiparasitic T-cell immunity and enhances the efficacy of PD-1 blockade (15 words).

Immune exhaustion corresponds to a loss of effector function of T cells that associates with cancer or chronic infection. Here, our objective was to decipher the mechanisms involved in the immune suppression of myeloid-derived suppressor cells (MDSCs) and to explore the potential to target these cells for immunotherapy to enhance checkpoint blockade efficacy in a chronic parasite infection. We demonstrated that programmed cell-death-1 (PD-1) expression was significantly upregulated and associated with T-cell dysfunction in advanced alveolar echinococcosis (AE) patients and in Echinococcus multilocularis-infected mice.

Regioselective epitaxial growth of metallic heterostructures.

Constructing regioselective architectures in heterostructures is important for many applications; however, the targeted design of regioselective architectures is challenging due to the sophisticated processes, impurity pollution and an unclear growth mechanism. Here we successfully realized a one-pot kinetically controlled synthetic framework for constructing regioselective architectures in metallic heterostructures. The key objective was to simultaneously consider the reduction rates of metal precursors and the lattice matching relationship at heterogeneous interfaces.

Immunological Characteristics of Hepatic Dendritic Cells in Patients and Mouse Model with Liver Infection.

The cestode which mainly dwells in the liver, leads to a serious parasitic liver disease called alveolar echinococcosis (AE). Despite the increased attention drawn to the immunosuppressive microenvironment formed by hepatic AE tissue, the immunological characteristics of hepatic dendritic cells (DCs) in the AE liver microenvironment have not been fully elucidated. Here, we profiled the immunophenotypic characteristics of hepatic DC subsets in both clinical AE patients and a mouse model.

Commercializable Naphthalene Diimide Anolytes for Neutral Aqueous Organic Redox Flow Batteries.

And a pot culture experiment was conducted to investigate the response of the rhizosphere microecology of these two rice varieties.

The cross-interface energy-filtering effect at organic/inorganic interfaces balances the trade-off between thermopower and conductivity.

The energy-filtering effect has been widely employed to elucidate the enhanced thermoelectric properties of organic/inorganic hybrids. However, the traditional Mott criterion cannot identify the energy-filtering effect of organic/inorganic hybrids due to the limitations of the Hall effect measurement in determining their carrier concentration. In this work, a carrier concentration-independent strategy under the theoretical framework of the Kang-Snyder model is proposed and demonstrated using PANI/MWCNT composites.

A Sodium-Ion-Conducting Direct Formate Fuel Cell: Generating Electricity and Producing Base.

A barrier that limits the development of the conventional cation-exchange membrane direct liquid fuel cells (CEM-DLFCs) is that the CEM-DLFCs need additional base to offer both alkaline environment and charge carriers. Herein, we propose a Na -conducting direct formate fuel cell (Na-DFFC) that is operated in the absence of added base. A proof-of-concept Na-DFFC yields a peak power density of 33 mW cm at 60 °C, mainly because the hydrolysis of sodium formate provides enough OH and Na ions, proving the conceptual feasibility.

Theoretically, the cell voltage of the high-temperature alkaline DFFC can be as high as 1.
