Enhancing phage therapy by coating single bacteriophage-infected bacteria with polymer to preserve phage vitality.

The efficacy of bacteriophages in treating bacterial infections largely depends on the phages' vitality, which is impaired when they are naturally released from their hosts, as well as by culture media, manufacturing processes and other insults. Here, by wrapping phage-invaded bacteria individually with a polymeric nanoscale coating to preserve the microenvironment on phage-induced bacterial lysis, we show that, compared with naturally released phages, which have severely degraded proteins in their tail, the vitality of phages isolated from polymer-coated bacteria is maintained. Such latent phages could also be better amplified, and they more efficiently bound and lysed bacteria when clearing bacterial biofilms.

Cbfβ: A key regulator in skeletal stem cell differentiation, bone development, and disease.

The skeletal system comprises closely related yet functionally distinct bone and cartilage tissues, regulated by a complex network of transcriptional factors and signaling molecules. Among these, core-binding factor subunit beta (Cbfβ) emerges as a critical co-transcriptional factor that stabilizes Runx proteins, playing indispensable roles in skeletal development and homeostasis. Emerging evidence from genetic mouse models has highlighted the essential role of Cbfβ in directing the lineage commitment of mesenchymal stem cells (MSCs) and their differentiation into osteoblasts and chondrocytes.

Notch signaling pathway in osteogenesis, bone development, metabolism, and diseases.

The skeletal system provides vital importance to support organ development and functions. The Notch signaling pathway possesses well-established functions in organ development and cellular homeostasis. The Notch signaling pathway comprises five typical ligands (JAG1, JAG2, DLL1, DLL3, and DLL4), four receptors (Notch1-4), and four intracellular domains (NICD1-4).

Generating Self-Adjuvated Nanofiber Vaccines by Coating Bacterial Flagella with Antigens.

However, the application of bacteria as therapeutic agents inevitably suffers from infection-associated side effects due to the living characteristics. Here, the use of bacteria-derived flagella is described to construct self-adjuvated nanofiber vaccines.

Correlation between gallstones and fasting blood glucose to serum high-density lipoprotein cholesterol ratio among American adults.

Background: Research indicates that the ratio of fasting blood glucose (FBG) to serum high-density lipoprotein cholesterol (HDL-C) (GHR) can accurately predict many diseases. Nevertheless, the relationship between GHR and the risk of gallbladder stones remains unclear. This study investigates the possible relationship between GHR and the incidence of gallbladder stones.

In situ construction of a Li-Ag&LiF interface enables stable cycling of all-solid-state lithium-metal batteries.

Solid polymer electrolytes (SPEs) are regarded as promising candidates for developing high energy-density Li metal batteries because of their flexible processability and low cost. However, the application of SPEs is still inherently impeded by the mediocre ionic conductivity and unstable Li/electrolyte interface. In this work, the silver fluoride (AgF) additive is introduced to optimize the ionic conductivity of PEO and induce the formation of stable solid electrolyte interphase (SEI) layer between Li metal and SPEs interface, thereby inhibiting the growth of lithium dendrites.

Noncontact microbiota transplantation by core-shell microgel-enabled nonleakage envelopment.

Transplantation of beneficial bacteria to specific microbiota has been widely exploited to treat diseases by reshaping a healthy microbial structure. However, direct exposure of exogenous bacteria in vivo suffers from low bioavailability and infection risk. Here, we describe a noncontact microbiota transplantation system (NMTS) by core-shell microgel-enabled nonleakage envelopment.

Hyaluronic Acid-Nanocoated Bacteria Generate an Anti-Inflammatory Tissue-Repair Effect in Impaired Gut and Extraintestinal Organs.

Diverse extraintestinal diseases are characterized by localized inflammatory responses and tissue damage, accompanied with intestinal inflammation and injury. Here, a dual-functionality and dual-location intervention strategy is reported, which is the use of hyaluronic acid-nanocoated Clostridium butyricum to generate an anti-inflammatory tissue-repair effect in the impaired gut and extraintestinal organs. Nanocoated bacteria attenuate intestinal mucosal inflammation and recover gut barrier integrity by leveraging the immunosuppressive nature of hyaluronic acid and the butyrate-producing ability of Clostridium butyricum.

Astrocytic P2X7 receptor in retrosplenial cortex drives electroacupuncture analgesia.

P2X7 receptor (P2X7R) has been found to contribute to the peripheral mechanism of acupuncture analgesia (AA). However, whether it plays an important role in central mechanism remains unknown. In this study, we aimed to reveal the role of astrocytic P2X7R in retrosplenial cortex (RSC) in AA and provide new evidence for underlying the central mechanism of AA.

Combining radiomics and molecular biomarkers: a novel economic tool to improve diagnostic ability in papillary thyroid cancer.

Reinforcement of the intestinal mucosal barrier via mucus-penetrating PEGylated bacteria.

The breakdown of the gut's mucosal barrier that prevents the infiltration of microorganisms, inflammatory cytokines and toxins into bodily tissues can lead to inflammatory bowel disease and to metabolic and autoimmune diseases. Here we show that the intestinal mucosal barrier can be reinforced via the oral administration of commensal bacteria coated with poly(ethylene glycol) (PEG) to facilitate their penetration into mucus. In mice with intestinal homoeostatic imbalance, mucus-penetrating PEGylated bacteria preferentially localized in mucus at the lower gastrointestinal tract, inhibited the invasion of pathogenic bacteria, maintained homoeostasis of the gut microbiota, stimulated the secretion of mucus and the expression of tight junctions, and prevented the mice from developing colitis and diabetes.

A real-world pharmacovigilance study of FDA adverse event reporting system events for Capmatinib.

Capmatinib is a potent selective mesenchymal-epithelial transition inhibitor approved in 2020 for the treatment of metastatic non-small cell lung cancer. As real-world evidence is very limited, this study evaluated capmatinib-induced adverse events through data mining of the FDA Adverse Event Reporting System database. Four disproportionality analysis methods were employed to quantify the signals of capmatinib-related adverse events.

Surface-modified bacteria: synthesis, functionalization and biomedical applications.

The past decade has witnessed a great leap forward in bacteria-based living agents, including imageable probes, diagnostic reagents, and therapeutics, by virtue of their unique characteristics, such as genetic manipulation, rapid proliferation, colonization capability, and disease site targeting specificity. However, successful translation of bacterial bioagents to clinical applications remains challenging, due largely to their inherent susceptibility to environmental insults, unavoidable toxic side effects, and limited accumulation at the sites of interest. Cell surface components, which play critical roles in shaping bacterial behaviors, provide an opportunity to chemically modify bacteria and introduce different exogenous functions that are naturally unachievable.
