Decades of research into antifouling surfaces have suggested that addressing this issue will require a sustained approach focused on incremental advances in chemical design. The creation of highly hydrophilic surfaces has long been recognized as a key strategy, initially pursued through polyethylene glycol-functionalized coatings. More recently, zwitterionic groups have emerged as effective antifouling moieties. However, the limited chemical diversity of zwitterion-forming chemical entities has constrained further progress. In this study, an alternative approach to enhancing surface hydrophilicity is presented by employing multicharged zwitterionic molecules (MZWs), which increase the density of charged hydrophilic groups per monomer unit. Surfaces functionalized with MZWs exhibited 40-45% lower protein adsorption compared to benchmark single zwitterionic molecules. Remarkably, the synthesized MZWs spontaneously assemble into vesicular aggregates (130-170 nm) without the need for additives or any form of external force. These findings strongly support further exploration of MZW-functionalization as a novel strategy to enhance antifouling performance, while remaining readily adaptable via minor modifications to existing synthetic routes used for the incorporation of conventional zwitterions into polymers, self-assembled monolayers, hydrogels, and nanocarriers.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e14739"},"PeriodicalIF":14.1,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145353148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microglial clearance of these toxic aggregates is essential, yet the underlying mechanisms remain poorly understood. This study demonstrates that low-dose ionizing radiation (LDIR) provides protection against Aβ toxicity in vitro and rescues cognitive deficits in sporadic, young, and aged familial AD mouse models, including reductions in Aβ plaque, tauopathy, and microgliosis, while promoting microglial phagocytosis in aged 3xTg-AD mice. Transcriptomic analysis identifies VUF6002, a histamine H4 receptor (H4R) antagonist, which mimics the beneficial effects of LDIR by promoting microglial activity. VUF6002 treatment restores cognitive function in aged 3xTg-AD and APPswe/PSEN1dE9 mice and significantly increases Aβ and p-tau clearance by resident microglia. Mechanistically, deletion of Hrh4 in microglia, but not in neurons, reverses cognitive deficits and mitigates key AD pathogenesis by activating the cAMP/TGF-β1/Smad3 pathway. These beneficial effects are completely abolished by inhibition of TGF-β receptor 1 signaling, which is also downregulated in AD patients. Collectively, these findings reveal a H4R/cAMP/TGF-β1/Smad3 signaling axis involved in microglial phagocytosis and cognitive function, serving as a novel therapeutic target for AD.","PeriodicalId":117,"journal":{"name":"Advanced Science","volume":" ","pages":"e05421"},"PeriodicalIF":14.1,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145353197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a high-throughput parallel chromatic-zone screening strategy is developed that enables the simultaneous screening of composition and surface structure, thereby optimizing antimicrobial performance. As an example, a MgCuPdGd alloy library with diverse compositions and nanostructures, consisting of 229 samples with continuous compositional gradients and varied nanostructured morphologies is constructed by integrating magnetron co-sputtering and chemical dealloying. The dealloyed samples exhibit distinct chromatic zones-red, yellow, and green-each associated with unique compositional and microstructural features. Among these regions, the red Cu-rich region demonstrates the most outstanding antibacterial performance, achieving a 95% reduction of viable Staphylococcus aureus (S. aureus). Comprehensive characterization confirms that the superior antimicrobial efficiency originates from the synergistic contribution of the CuPd alloy and the optimized nanostructure. Furthermore, the observed correlation among surface color, composition, morphology, and antibacterial performance highlights the predictive capability of the chromatic-zone screening approach, thereby reducing characterization requirements by 90% and enabling morphology and performance estimation across large material libraries.

However, the underlying neural mechanism is poorly known. Using an olfactory cued Go/No-Go task, this work finds increased false alarm rate, shortened licking onset latency, elevated licking frequency and reduced inter-trial consistency in mice treated by the NMDAR antagonist (MK-801). Fiber optic recordings reveal MK-801 enhanced cue-evoked neuronal responses in the olfactory bulb (OB), orbitofrontal cortex (OFC), ventral tegmental area (VTA), and nucleus accumbens (NAc), while reducing reward-predictive cue selectivity and increasing NAc dopamine release. Additionally, in vivo electrophysiological recordings demonstrate that theta oscillation power in the NAc and its coherence with OB, OFC, and VTA are also amplified. MK-801 treatment enhances the correlation between firing rates of NAc neurons and cue, decreases the association with reward, strengthens the correlation with licking and increases the probability of firing peak preceding lick onset. Furthermore, this work confirms that the application of the trace amine-associated receptor 1 agonist SEP-363856 could correct the abnormal responses of NAc neurons and behavioral deficits.

Here, a co-self-assembled monolayer (Co-SAM) engineering strategy is implemented by integrating 4-nitrophenyl phosphate (PNPP) into [4-(3,6-dimethyl-9H-carbazol-9-yl) butyl] phosphonic acid (Me-4PACz) to improve the NiOx/perovskite (PVK) interface. This technique enhanced the surface uniformity and hydrophilic nature of the NiOx/Me-4PACz, while promoting favorable growth of PVK crystal orientation. Furthermore, the PNPP effectively mitigates the generation of defects at the NiOx surface and the underlying PVK, ultimately significantly improving the interfacial charge transfer efficiency. Consequently, the efficiency of F-PSCs rose from 21.46% to 23.66%. Due to better stress distribution within the PVK and stronger adhesion at the NiOx/PVK boundary, the F-PSCs retained 80% of their original efficiency even after undergoing 10 000 bending cycles.
