LuxS catalyzes the synthesis of the quorum-sensing signaling molecule autoinducer 2. We show that in Salmonella enterica serovar Typhimurium, deletion of the luxS gene polarizes flagellar phase variation toward the more immunogenic phase 1 flagellin ...

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide
Advanced Science, EarlyView.This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

, 2018 Vibrio parahaemolyticus is a seafood opportunistic pathogen. There are evidences suggesting that virulence skills, including hemolytic activity and biofilm formation, are regulated by the luxM/luxS-dependent quorum-sensing system in V.

Discrete 2D Material Programming for 3D Shaping and Morphogenesis‐Inspired 4D Bioprinting
Advanced Science, EarlyView.Cell‐compatible discrete 2D material programming enables 2‐to‐3D shape transformation and morphogenesis‐inspired 4D bioprinting. By patterning cell‐supportive microdomains within a responsive hydrogel, the approach programs in‐plane growth to encode target metrics.

Advanced Science, EarlyView.Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis
Advanced Science, EarlyView.A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...

Effect of crp on luxS::lacZ expression in absence or presence of uvrY.
, 2016 Strains SM1005 (luxS::lacZ), SM1007 (ΔuvrY luxS::lacZ), SM1040 (Δcrp::kan luxS::lacZ) and SM1041 (Δcrp::kan ΔuvrY::cam luxS::lacZ) were grown in TB and β-galactosidase expression was measured at indicated time points.

Figures de l'Art. Revue d'études esthétiques, 2009 Dotée de la fausse évidence que lui confèrent son statut et son omniprésence dans le monde des “voyants” que nous sommes, la lumière semble pourtant difficile à appréhender et à apercevoir. La richesse des valeurs qui lui sont culturellement attachées nous a incitée à limiter notre étude à celle d’un paradigme expressif et à un univers sémantique et ...

Overcoming Drug Resistance by Paclitaxel Resistance in Triple‐Negative Breast Cancer
Advanced Science, EarlyView.In the murine triple‐negative breast cancer (TNBC) model, chemotherapy effectively increases tumor neoantigen burden (TNB). Here, the study constructs a liposomal nanovaccine using antigens derived from in vitro chemotherapy‐treated paclitaxel‐resistant TNBC 4T1 cells.

Effect of luxS complementation on biofilm formation by C. ochracea.
, 2016 C. ochracea ATCC27872, LKT7 (luxS∷tetQ), and luxS-C3 (luxS complemented strain) were incubated in TS broth for 48 h under anaerobic conditions. Biofilm formation was then assayed by means of crystal violet staining.
