In eukaryotic systems, three major types of cell junctions have been well characterized. While bacterial adhesion mechanisms also exhibit remarkable diversity, the molecular processes that regulate the dynamic modulation of binding strength between elongated bacterial cells and host cells remain poorly understood. () utilizes the surface adhesin CbpF to interact with the highly expressed host receptors CEACAM1 and CEACAM5 on cancer cells to facilitate tumor colonization.

Through molecular dynamics simulations of imidazolium-based ionic liquid-water mixtures, it was found that the trace water leads to an anomalous non-monotonic change in the diffusion coefficients of ionic liquid, characterized by an initial decrease followed by an increase. Hydrogen bond analysis revealed that this unusual trend is governed by the weighted hydrogen bond lifetime, reflecting the stability of the hydrogen-bond network, rather than simply the number or energy of hydrogen bonds.

The stimulator of interferon genes (STING) pathway represents a promising target in cancer immunotherapy. However, the clinical translation of cyclic dinucleotide (CDN)-based STING agonists remains hindered by insufficient formation of functional CDN-STING complexes. This critical bottleneck arises from two interdependent barriers: inefficient cytosolic CDN delivery and tumor-specific STING silencing via DNA methyltransferase-mediated promoter hypermethylation.

Longzihu New Energy Laboratory, Zhengzhou Institute of Emerging Industrial Technology, Henan University, Zhengzhou 450000, China.

We synthesized two linear dopant-free hole transport materials (HTMs), denoted as NT and iNT, by coupling methoxytriphenylamine donor unit with either naphtho[1,2-:5,6-']bis[1,2,5]thiadiazole or its isomeric counterparts naphtho[1,2-:5,6-']bis([1,2,3]thiadiazole) as acceptor units. The fused-ring isomerization structure of iNT endows it with a substantial dipole moment and well-aligned energy levels, which are highly favorable for efficient free-charge extraction. Compared to devices based on NT, CsPbI inorganic perovskite solar cells (IPSCs) employing iNT exhibited significantly enhanced performance, achieving a power conversion efficiency (PCE) of 18.

Solid-state lithium metal batteries (SSLMBs) are promising for realizing higher energy density. However, the poor interfacial Li transport kinetics and Li dendrite growth inhibit SSLMBs, leading to sluggish interfacial ion diffusion and depressive lifespan, which is attributed to high barriers blocked by anions or interface space in solid-state electrolytes. Herein, a flexible solid-state polymer skeleton employed with ionic liquid and metal-organic frameworks (PIM) electrolyte is proposed to strengthen interfacial Li ion exchange by improving the Li sieving effect and interfacial wettability.

Tuning interfacial water structures is a fundamental yet underexplored strategy for advancing the hydrogen evolution reaction (HER) and broader electrocatalytic processes. Here, we demonstrate a universal and scalable catalytic optimization strategy via the magnetic field-driven reconfiguration of interfacial water at the molecular level. Unlike conventional magnetohydrodynamic (MHD) strategies focusing on mass transport, this work pioneers a molecular-level interfacial water structure modulation via the vibrational Stark effect (VSE), achieving intrinsic catalytic enhancement for HER.

The pathogenesis of interstitial cystitis/bladder pain syndrome (IC/BPS) remains unclear, and there is no definitive treatment for this condition. Studies have shown that antisense oligonucleotide (asODN) targeting nerve growth factor (NGF) can downregulate the level of NGF in the bladder, however, the uptake of NGF asODN by the body is limited. Therefore, this study constructed cationic liposomes (CLs) as a delivery system to carry NGF asODN and evaluated its functional efficacy on the bladder.

Glycans are one of the most important biomacromolecules and are essential to nearly all known life forms. However, their structural complexity makes structural analysis more challenging than nucleic acids or proteins, significantly limiting the opportunities for investigating their structure-function relationship. Here, we proposed a novel glycan sequencing strategy in which a suite of specific non-reducing-end exoglycosidases was integrated with electrochemical detection of monosaccharides in a digital microfluidic (DMF) chip.

As the need for antibody production rises, there is an urgent need to lower the costs and enhance the efficiency of the separation process. Currently, the chromatographic media used for antibody separation and purification often focus on individual properties of antibodies, such as affinity, hydrophobicity, and charge, leading to issues like low purification efficiency or inadequate adsorption capacity. To address this, an electrostatically coupled polypeptide affinity medium (FD7-3, 5-diaminobenzoic acid n-sepharose, FD7-DA-Sepharose) was developed for rapid purification of antibodies from cell culture supernatant.
