We constructed a novel excellent photodynamic drug without heavy atoms based on the conventional BODIPY photosensitizer, and then obtained a photodynamic vesicle with efficient tumor targeting (BDPM@OMVs) by bacterial extravasation. Multiple reactive oxygen species were efficiently generated under light irradiation, and the spontaneous elimination of ...

The aim of this work is to propose a first coarse-grained model of Bacillus subtilis cell wall, handling explicitly the existence of multiple layers of peptidoglycans. In this first work, we aim at the validation of the recently proposed "three under two"

This randomized, double‐blind, placebo‐controlled trial evaluated the effects of live probiotic and HT postbiotic B. longum CECT 7347 in adults with moderate–severe allergic rhinitis. Postbiotic supplementation for 8 weeks significantly reduced CSMS and dSS, exceeding the established CSMS MCID with a 33% greater improvement, when compared to placebo ...

Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.

Bacillus subtilis MurJ and Amj Lipid II flippases are not essential for growth
Identification of the protein that mediates transbilayer transport of the undecaprenyl-pyrophosphate (Und-PP) linked peptidoglycan precursor Lipid II has long been a subject of investigation.

Polyphosphate interaction with Hfq and RNA drives phase separation and amyloid self‐assembly, uncovering a previously unrecognized role for polyP in bacterial stress responses. Our findings reveal new insights into the molecular mechanisms of RNA‐mediated phase separation, highlighting the role of polyP as a key modulator of this process. Polyphosphate

Human RNase 7 is known to exert antimicrobial activity in epithelial tissues. Here, using SH‐SY5Y and U‐87 MG, neuroblastoma and glioblastoma cell lines, respectively, we found that RNase 7 enhances immune responses to LPS stimulation by reducing the expression of pro‐inflammatory cytokines, nitric oxide, and ROS.

ADAM17 and its proteolytic targets in disease pathogenesis
ADAM17 as a multifunctional sheddase with contrasting roles across inflammatory, metabolic, cardiovascular, and neoplastic diseases. Through regulated activation by iRhom, iTAP/FRMD8, and tetraspanins, ADAM17 cleaves diverse membrane ligands and receptors, thereby promoting inflammation, fibrosis, obesity, insulin resistance, and tumor progression ...

The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and
