Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

open access: yesSmall, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Extracellular vesicles in pharmacology: Innovations in drug delivery and therapeutic applications in cancer

open access: yesBritish Journal of Pharmacology, EarlyView.
Extracellular vesicles (EVs) are a diverse population of membrane nanoparticles secreted by nearly all cell types, playing a key role in intercellular communication by transferring bioactive macromolecular cargo. In cancer, EVs shape both the local tumour microenvironment and distant premetastatic niches.

Dental resin composites generate microparticles and impact on gingival keratinocytes—In vitro study

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Along with our increased understanding of the spread of microplastic pollution, the awareness of microparticle release from medical and dental materials has increased. Still, their effects on human health are largely unknown. As the use of resin composite materials in dentistry continues to increase, it is essential to understand the formation

SHIP1 regulates TREM2 signalling and macrophage functions in a hiPSC‐derived model

open access: yesThe FEBS Journal, EarlyView.
In this study, we characterised the role of SHIP1 in regulating TREM2 signalling and global microglial myeloid functions using human‐induced pluripotent stem cell (hiPSC)‐derived macrophages. Knockout of SHIP1 (SHIP1 KO) in macrophages decreased inflammatory activation and levels of scavenger receptors. SHIP1 KO macrophages also exhibited reduced TREM2

Immunometabolic Modulation by Low‐Dose Sodium Butyrate: PI3K/Akt/mTOR Signalling Orchestrates Macrophage Polarization to Protect Against Clostridioides difficile Colitis

open access: yesImmunology, EarlyView.
Clostridioides difficile toxins TcdA and TcdB enter intestinal epithelial cells (IECs) via specific receptors, disrupt tight‐junction integrity and activate PI3K/Akt/mTOR signalling, promoting inflammasome assembly and IL‐1β release. Toxin‐induced IEC apoptosis further weakens the epithelial barrier.

Stem Cells From Dental Pulp, Periodontal Tissues, and Other Oral Sources: Biological Concepts and Regenerative Potential

open access: yesJournal of Periodontal Research, EarlyView.
A graphical abstract recapping the different sources of dental, periodontal, and other oral‐derived mesenchymal stromal cells (MSCs) and their regenerative mechanisms and potentials. The review's article findings bridge fundamental biological science with translational advances, highlighting the significance of MSCs in craniofacial regenerative ...
