The structural conversion of β-lactoglobulin (β-LG) into amyloid fibrils offers an effective strategy for developing functional biomaterials with enhanced physicochemical properties and functionalities. This study investigated the effect of cold plasma (CP) and ultrasound pretreatments on β-LG fibril (β-LGF) under acid-heat conditions (pH 2.0, 90 °C, 10 h) and explored the relationship between fibril structure and functional performance. Compared with the control, CP pretreatment significantly increased ThT fluorescence intensity by 1.9-fold, indicating enhanced fibril formation. Dynamic light scattering revealed that CP-treated fibrils (P-β-LGF) exhibited a reduced average particle size (183.6 ± 4.7 nm) and narrower distribution (PDI = 0.21) compared with ultrasound-treated (243.1 ± 6.5 nm) and control samples (278.4 ± 7.8 nm). FTIR and CD spectra confirmed the structural transition from α-helix to β-sheet, while SEM micrographs showed elongated, uniformly dispersed fibrils after CP pretreatment. Functionally, P-β-LGF exhibited the highest emulsifying activity index (51.2 m 2 /g), emulsion stability index (87.3%), and antioxidant activities, the emulsions stabilized by P-β-LGF-Dextran complex exhibited the superior thermal and ultraviolet stability of encapsulated lycopene. The highest retention rate (91.6%) was obtained in the emulsion. These findings demonstrated that CP treatment is an effective, green, and tunable strategy to regulate protein conformation and fibrillation kinetics, thereby enhancing the structural and functional properties of β-LG, providing new insights into the design of protein-based delivery systems for bioactive compounds.

Acupuncture exerts its therapeutic effects through complex mechanical cues, including compressive forces from needle insertion and retention, and tensile stresses from extracellular matrix deformation during needle twisting. How these biomechanical stimuli regulate mast cell function at the molecular level remains poorly understood due to the lack of tools capable of replicating such multifaceted forces. Here, we report a magneto-responsive biosensor that enables multimodal simulation of stretching, compression, and combined loading in both static and cyclic modes. This allows for closely recapitulating the mechanical environment of mast cells during acupuncture, while simultaneously monitoring mechanically evoked cellular serotonin (5HT) release in real time. Using this sensor, we demonstrate that cyclic combined stimulation significantly amplifies cell responses by promoting both 5-HT release and intracellular biosynthesis. Furthermore, in vivo experiments at acupoints confirmed the “release-replenishment” phenomenon observed in vitro. Collectively, this study provides mechanistic insights into the molecular basis of acupuncture therapy and establishes a versatile tool for probing mechanobiological regulation in living systems.

The treatment of bacterial wound infection, particularly that caused by methicillin-resistant Staphylococcus aureus (MRSA), presents significant challenges owing to biofilm formation, multidrug resistance, and immune evasion. Here, we have rationally designed a multifunctional composite nanozyme (FTM) consisting of tannic acid (TA) and ferric ion (Fe 3+ ) coordination compound loaded with antibiotic drug methicillin (Meth), which is capable of realizing pH-responsive self-adaptive regulation of oxidative stress for enhancing the treatment of MRSA-infected wound. During the early stages of wound infection (pH < 6.5), FTM demonstrates significant peroxidase-like activity for effectively catalyzing the conversion of endogenous H 2 O 2 into highly toxic hydroxyl radical (•OH), which not only directly damages MRSA and eliminates its biofilm for chemodynamic therapy (CDT), but also disrupts the penicillin-binding protein 2a (PBP2a) to restore the sensitivity of MRSA to methicillin. Meanwhile, FTM exhibits strong near-infrared (NIR) absorption, achieving photothermal antibacterial therapy (PTT). While in the later stages (after complete elimination of MRSA), as the infectious microenvironment of wound becomes neutral (pH 7.4), FTM mainly reveals the superoxide dismutase (SOD)-like activity for scavenging excess reactive oxygen species (ROS), ultimately reducing oxidative stress and promoting tissue repair. In vitro and in vivo experiments show that the proposed FTM nanozyme with triple bactericidal modalities achieves satisfactory antibacterial and antibiofilm therapy and accelerates wound healing process. Consequently, by adapting to the dynamic changes of wound microenvironment, this multifunctional nanoplatform offers a promising strategy for treating drug-resistant wound infections.

Senescence is widely recognized as a key driving factor in the onset and progression of many chronic diseases. Although numerous animal studies have demonstrated that various drugs can delay senescence, their clinical application is severely limited due to significant toxic side effects. As a result, developing safer, natural anti-senescence agents has become an urgent priority. In this study, we identified mitochondrial dysfunction as a critical contributor to cellular senescence. In addition, we identified Shenrong Guben Huanshao Pill (SRW) as an effective agent that alleviates mitochondrial dysfunction and consequently delays cellular senescence by regulating mitochondrial metabolism. Mechanistically, SRW enhances mitochondrial function by upregulating the expression of NADH:ubiquinone oxidoreductase subunit V2 (NDUFV2), a core component of mitochondrial respiratory chain complex I. Simultaneously, SRW reduces lactate-induced mitochondrial dysfunction by regulating the glycolytic enzyme lactate dehydrogenase B (LDHB), thereby decreasing lactate accumulation. Collectively, our findings indicate that SRW alleviates cellular senescence by coordinately regulating NDUFV2 expression and LDHB-mediated lactate metabolism to improve mitochondrial function. In addition, several flavonoids in SRW were identified to possess potential anti-senescence activity. Molecular docking and cellular experiments confirmed that myricetin, luteolin, and gamma-mangostin effectively alleviate cellular senescence.

Tetrabromobisphenol A (TBBPA), a prominent brominated flame retardant (BFR), is a toxic pollutant. In view of the structural similarity of TBBPA to thyroid hormones, we investigated the toxic effects of TBBPA on human thyroid follicular epithelial cells (Nthy-ori3–1) at concentrations ranging from 0.02 to 100 μM. The findings of this study demonstrated that a 24-hour exposure to 10 μM TBBPA resulted a reduction of cell viability to 50.9 %. Concurrently, intracellular reactive oxygen species (ROS) levels were significantly elevated, and oxidative stress-related proteins, particularly those involved in the NRF2/KEAP1 pathway, were upregulated in the cells. It is noteworthy that, while catalase (CAT) activity increased, T-SOD enzyme activity was inhibited. To better understand the mechanism underlying the interaction between TBBPA and antioxidant enzymes, multispectral methods and molecular docking techniques were employed. These analyses revealed that TBBPA binds to antioxidant enzymes and induces structural changes that may impair their function. Altered enzyme activity may lead to abnormal ROS accumulation and contribute to apoptosis. Furthermore, the interactions between TBBPA and Cu/Zn-SOD and CAT have been demonstrated to exacerbate this process. This study provides valuable insights into the molecular mechanisms underlying TBBPA-induced thyroid cell toxicity.

Pinellia ternata (Thunb.) Breit. has been used in China for more than two thousand years to treat cough and vomiting. P. ternata is rich in polysaccharides; however, current research on the bioactivity of polysaccharides from P. ternata is relatively limited. In particular, there are no reports on their application in the treatment of osteoporosis. In this study, two β -glucan-like polysaccharides were isolated from P. ternata . The primary structures of PTTP50–1-3 and PTTP50–1-4 were comprehensively analyzed using high performance liquid chromatography, gas chromatography–mass spectrometry, and nuclear magnetic resonance. The results indicated that they possess a similar backbone structure. Notably, compared with PTTP50–1-3, PTTP50–1-4 exhibits characteristics of a higher degree of branching, a higher β -glucan content, and a lower molecular weight. In vitro experiments demonstrated that both PTTP50–1-3 and PTTP50–1-4 could increase the alkaline phosphatase activity of MC3T3-E1 cells. In addition, PTTP50–1-4 was able to enhance the mineralization of MC3T3-E1 cells by upregulating the expression of Runx2 , Osx , Bmp2 , Ocn , Opn , and Bsp mRNA. These findings suggest that P. ternata polysaccharides with a β -glucan-like structure may possess strong anti-osteoporotic potential, which provides a theoretical foundation for further research and development of P. ternata polysaccharides in the prevention and treatment of osteoporosis.

Effective blood glucose management is an increasing demand worldwide. Traditional solutions separate glucose detection and insulin delivery, which is less efficient compared to emerging closed-loop wearable systems controlled by continuous glucose monitors (CGMs). However, CGM-controlled systems raise new safety risks, as false CGMs readings can cause insulin overdose, which results in hypoglycemia and fatal consequences. This work proposes a concept of a dual closed-loop insulin delivery system (DuoLoop) to mitigate the risk issue of CGM-controlled systems. The first closed-loop is automated insulin delivery controlled by CGM. The second closed-loop is the controlled release of glucose-responsive insulin (GRI), whose release rate depends on actual glucose levels. A customized algorithm is trained and embedded into the wearable CGMs for edge computing. The DuoLoop system shows improved safety in preliminary in vivo test (longer normoglycemia durations, 98.82% vs 92.10%), encouraging its deployment toward precision diabetes care.

Enzyme catalysis is widely used in industrial bioprocesses, but free enzymes often suffer from low stability, poor reusability, and limited mass transfer. Capsule encapsulation improves stability by providing a cell-mimetic confined microenvironment, while limited shell permeability often restricts mass transfer, reducing catalytic activity. In this work, the immobilized enzyme system (MDH@OSN-RCC2) was prepared by incorporating the porous organic cage RCC2 into an organosilica network (OSN) for the encapsulation of mannitol dehydrogenase (MDH). RCC2 integration adjusted the capsule’s pore structure. At 3 g L −1 RCC2, the specific surface area and total pore volume increased by 3.48-fold and 3.31-fold, the diffusion rate of fructose increased 6.84-fold, and the catalytic efficiency ( k cat / K m ) was 2.05-fold higher than MDH@OSN. The system retained 71.8 % of initial activity after 11 reuse cycles and performed stably over a broad temperature and pH range. This strategy was also applied for whole-cell immobilization that exhibited excellent operational stability and environmental tolerance. This study offers a design principle for durable biocatalysts in industrial and green biomanufacturing applications.

In this study, the hexane extract of Asters tataricus was used as the carbon source, and ethylenediamine and 4-bromophenylene diamine were selected as dopants to prepare nitrogen and bromine co-doped carbon dots (N,Br-CDs) by the hydrothermal synthesis method. The obtained fluorescent probe has a uniform particle size distribution, good water solubility and high stability, with a fluorescence quantum yield of 48.43%. Under 420 nm excitation conditions, N,Br-CDs exhibited the strongest fluorescence emission at 513 nm, indicating that the sensing system was in the “ON” state. Subsequently, TA was introduced as a quencher to induce static quenching of the N,Br-CDs system, significantly weakening the fluorescence intensity and switching the sensing system from “ON” to “OFF”. Finally, after EM was introduced into the N,Br-CDs/TA system, EM preferentially formed a complex with TA and weakened its quenching effect on the quantum dots, thereby achieving fluorescence recovery and returning the sensing system from the “OFF” state to the “ON” state. Based on the above mechanism, an “ON-OFF-ON” fluorescence sensing system with N,Br-CDs as the luminescent substrate was constructed for the sensitive detection of TA and EM. The results showed that the system exhibited good linear response to TA, with the linear ranges being 1.50–22.94 μM and 34.88–348.42 μM, respectively, and the limits of detection being 0.2168 μM and 2.1797 μM, respectively (LOD, S/N = 3). The linear range for EM was 1.93–377.08 μM, with a detection limit of 0.6693 μM. Furthermore, the sensor system was capable of quantitatively determining TA and EM in human serum, Huangshui River water, and milk matrices, demonstrating its potential for broad application in environmental monitoring and bioanalysis.

Prostate cancer remains one of the most common malignant tumors among men worldwide, and treatment options are limited in the advanced stage. To address this challenge, we have developed a pH-responsive copper porphyrin metal–organic framework (CuTCPP-MOF), which integrates photodynamic therapy (PDT) and chemodynamic therapy (CDT). It enables efficient electron transfer and ROS generation. Under 488 nm laser irradiation, MOF acts as a self-sensitizing photosensitizer to generate single-state oxygen (1O2), which gradually releases Cu2+ in an acidic environment. Subsequently, it is reduced to Cu+ by intracellular glutathione (GSH), achieving continuous consumption of GSH and enhancing the Fenton-like reaction to promote the continuous formation of hydroxyl radicals (˙OH). This amplifies the oxidative stress within tumor cells. In vitro experiments have shown that ROS accumulation and mitochondrial membrane depolarization lead to apoptosis of RM-1 prostate cancer cells. In vivo, CuTCPP-MOF combined with laser irradiation can significantly inhibit tumor growth without causing systemic toxicity and hemolysis. Histological analysis confirmed that after treatment, the apoptosis of tumor cells was enhanced and their proliferation ability was reduced. In conclusion, CuTCPP-MOF is a promising nano-therapeutic agent that can work in synergy with PDT and CDT to achieve effective and safe treatment of prostate cancer.

Introduction The poor bioavailability of luteolin, a potent flavonoid with antioxidant and anti-inflammatory properties, hinders its therapeutic potential. The primary barriers to its absorption are its low solubility and active efflux by P-glycoprotein (P-gp) in the gastrointestinal tract. Objectives To overcome these absorption barriers, we developed a functional self-microemulsifying drug delivery system (SME) incorporating D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS), aiming to simultaneously enhance solubility, inhibit P-gp efflux, and improve the oral bioavailability and therapeutic efficacy of luteolin. Methods A TPGS-based luteolin-SME was prepared via self-assembly and characterized for particle size, stability, release profile, and antioxidant capacity. Cellular absorption mechanisms, permeability, and P-gp inhibition were evaluated using Caco-2 monolayers and molecular docking. Pharmacokinetics and biodistribution were assessed in rats, and therapeutic efficacy was examined in a lipopolysaccharide-induced inflammation model. Results The optimized luteolin-SME formed uniform nanodroplets (<50 nm) with high stability and achieved a 4.3-fold higher cumulative release compared to free luteolin. In Caco-2 cells, the formulation significantly enhanced cellular uptake and permeability, primarily via clathrin- and caveolae-mediated endocytosis, and effectively inhibited P-gp efflux. Pharmacokinetically, luteolin-SME provided a 29-fold increase in relative bioavailability (AUC 247.729 vs. 8.628 mg/L·h) and a 16-fold higher Cmax (27.546 mg/L) over free luteolin. In the lipopolysaccharide-induced inflammation model, luteolin-SME markedly attenuated oxidative stress, reducing the TNF-α, IL-6, and IL-1β levels by approximately 37%, 26%, and 39%, respectively. Conclusion The TPGS-functionalized SME effectively overcame the major absorption barriers of luteolin by integrating nanocarrier-enhanced solubilization with active P-gp inhibition. This dual strategy resulted in unprecedented oral bioavailability enhancement and potent efficacy. Our study establishes a robust and clinically promising delivery platform for luteolin and other poorly soluble, efflux-limited bioactive compounds, offering a practical approach to enhance oral therapy for inflammation-related diseases.

Background Sepsis, a life-threatening condition, arises from an aberrant or uncontrolled immune response of the host to severe infection. Timely and precise control of this inflammatory response is of paramount importance in sepsis prevention and constitutes the core of sepsis prevention efforts. Parthenolide (PA), recognized as an NF-κB inhibitor, has previously demonstrated its capacity to mitigate the inflammatory response. This study aimed to investigate whether and how PA can inhibit inflammation, thereby alleviating sepsis, and to profile functional target proteins using chemoproteomics strategy. Methods The cecal ligation and puncture (CLP) procedure was performed to induce a mouse model of sepsis, and lipopolysaccharide (LPS) was employed to establish a model of cellular inflammation in mouse mononuclear macrophage cells (RAW264.7) in vitro . Enzyme-linked immunosorbent assay (ELISA) and hematoxylin and eosin (H&E) staining were utilized to evaluate the therapeutic effects of PA on septic mice. In the in vitro experiments, streamlined cysteine activity-based protein profiling (SLC-ABPP) and proteomics techniques were employed to identify potential protein targets and molecular pathways responsible for the anti-inflammatory properties of PA. Results We demonstrated that PA could enhance the survival rate, reduce inflammatory cytokines release, ameliorate histopathological changes, and balance macrophage polarization in a sepsis model. Similarly, PA could effectively alleviate the inflammatory response in LPS-stimulated RAW264.7 cells. Chemoproteomics profiling revealed that Trim33 protein was a potential covalent target of PA via cysteine engagement, and the expression changes of global proteins indicated by proteomics analysis suggested that PA mitigated inflammation by inhibiting the NF-κB pathway. Finally, through a series of molecular biology experiments, we confirmed that PA suppresses the NF-κB pathway by functionally binding to Trim33 and subsequently reducing the ubiquitin dependent degradation of Smad4, thereby exhibiting anti-inflammatory activity. Conclusion Our findings demonstrated that PA significantly mitigated inflammation in sepsis by targeting the Trim33 protein and consequently suppressing ubiquitination on Smad4 as well inhibiting the NF-κB pathway, thus providing new insights into the clinical use of PA in treatment of inflammation related diseases.
