A novel biomimetic liposome drug delivery system mediated by macrophage targeting for precision treatment of encephalitis

open access: yesBMEMat, EarlyView.
An advanced macrophage‐mediated biomimetic liposome (AC‐LP@RAW) that can penetrate the BBB and precisely target inflammatory sites in the deep brain was established in this study based on the unique immune homing property of macrophages, and showed a significantly improved delivery of curcumin to the brain.

Integrated spherical nucleic acid nanoreactor mobilizes targeted PD‐L1 proteolysis and cuproptosis for robust breast cancer immunotherapy

open access: yesBMEMat, EarlyView.
This study provides an integrated spherical nucleic acid nanoreactor (denoted as AMCuD) for targeted PD‐L1 degradation and chemo‐dynamically enhanced cuproptosis to synergically elicit robust immunotherapy against the triple‐negative breast cancer (TNBC) growth, recurrence and metastasis.

Tackling cancer stemness with nanotechnology in the era of precision medicine

open access: yesBMEMat, EarlyView.
Precise customization of nanoparticles (NPs) enables active targeting of cancer stem cells (CSCs), thereby improving drug delivery and therapeutic efficacy. NP‐based probing enhances CSC detection through imaging and liquid biopsy, whereas diverse therapeutic payloads improve therapeutic outcomes.

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

open access: yesBiological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Combination of autogenous dentin graft and allograft for horizontal ridge augmentation: A case report

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Autogenous particulate dentin has emerged as one of the promising biocompatible alternatives to traditional bone graft materials in alveolar ridge augmentation. Although its clinical success is documented, comprehensive studies combining histological and radiographic evaluations remain limited. This case report addresses this gap by

Bioenhancer‐Driven Modulation of Membrane Dynamics Improves B‐Vitamin Uptake in Caco‐2 Cells

open access: yesChemFoodChem, EarlyView.
Natural bioenhancers such as extracts from ginger, turmeric, black pepper, and spearmint increase the uptake of vitamins B1, B5, B6, and B7 in Caco‐2 cells. Micellized formulations further increase efficacy. These findings indicate that altered membrane fluidity contributes to enhanced cellular absorption, providing a new route to improve vitamin B ...

Bright Solvatochromic Fluorophores With Dual Emission Enabled by a Donor‐Engineering Strategy

open access: yesChemistry – A European Journal, EarlyView.
We screened tertiary amines for installation on the donor unit of highly emissive donor–acceptor‐type solvatochromic fluorophores based on a 9,9‐dimethyl‐2‐phenyl‐9H‐fluorene scaffold, with the aim of enabling two bright emissive states to coexist. As a result, the azetidine derivative [4] and the azepane derivative [7] exhibited clear dual emission ...
