Synthesis and Characterization of Novel Silylated Sm3+ and Eu3+ Complexes Incorporated Into Mesoporous Silica Nanoparticles

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
The strategy of incorporating the Eu(tta‐Si)3(phen) and Sm(tta‐Si)3(phen)2 complexes prevented leaching of the complexes and preserved their intrinsic optical properties. Preliminary studies of silylated Ln3+ complexes and nanoparticles loaded with these complexes demonstrated cytotoxicity against cancer cells, with minimal cytotoxic effect on nontumor

Identification of functional murine mitochondrial formyl peptides and their effects on myeloid‐derived suppressor cell generation

open access: yesFEBS Open Bio, Volume 16, Issue 7, Page 1387-1399, July 2026.
We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets

open access: yesAdvanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...

Tumor‐Intrinsic ARHGEF3 Enhances Antitumor Immunity by Promoting T‐Cell Infiltration and Limiting Myeloid Cell‐Mediated Immunosuppression

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
ARHGEF3 is broadly downregulated across human cancers and correlates with patient prognosis. Tumor‐intrinsic ARHGEF3 activates the RHOA–ROCK–PTEN cascade to inhibit AKT signaling, thereby promoting chemokine‐driven T‐cell infiltration and relieving lipid‐mediated myeloid immunosuppression.

Decoding the Mechanism of Action of a Parasite TGFβ Antagonist Inspires the Creation of Cell‐Type‐Specific TGFβ Modulators

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
The mammalian TGFβ interacts with ubiquitously expressed TGFBR1 and TGFBR2, and current TGFβ‐targeting agents are non‐cell‐selective. The cooperative interaction of the modular parasite TGFβ antagonist with multiple host (co‐)receptors empowers the design of TGM chimeras and bispecific antibodies that activate or inhibit TGFβ signaling in a cell ...

Supramolecular Coordination Platforms for Smart Theranostics: Leveraging the Dynamic Molecular Networks of Metal–Polyphenol Assemblies

open access: yesAggregate, Volume 7, Issue 7, July 2026.
In this review, we summarize the recent developments of metal–polyphenol networks (MPNs) as a highly versatile and functionally integrated supramolecular assembly platform. We also discuss their pivotal role in steering biomedical materials away from conventional single‐function designs and toward intelligent, unified diagnostic and therapeutic ...

Anti-Melanogenic Effects of L-Theanine on B16F10 Cells and Zebrafish

open access: yesMolecules
L-Theanine, a natural amino acid found in green tea (Camellia sinensis) leaves, is known for its diverse psychotropic effects. This study aimed to evaluate the inhibitory effect of L-theanine on melanin production and uncover its regulatory mechanism. We evaluated the anti-melanogenic activities of L-theanine in vitro and in vivo.

Bovine Milk–Derived Extracellular Vesicles as Emerging Drug Delivery Platforms: Current Advances, Applications and Challenges

open access: yesJournal of Extracellular Biology, Volume 5, Issue 7, July 2026.
ABSTRACT Extracellular vesicles (EVs) are nanosized lipid bilayer particles naturally secreted by cells, mediating intercellular communication and transporting diverse bioactive molecules. Among alternative EV sources, bovine milk‐derived EVs (BMEVs) have emerged as promising platforms for drug delivery due to their accessibility, scalability ...

Delivery Systems for Therapeutic Genome Editing: Challenges, Innovations, and Future Perspectives

open access: yesMedComm, Volume 7, Issue 7, July 2026.
Schematic illustration of four emerging CRISPR–Cas delivery platforms defined by distinct design principles and structural features: virus‐mimicking nanosystems (e.g., VLPs), cell‐derived extracellular vesicles, cell‐penetrating peptides, and stimuli‐responsive scaffolds. These platforms enable spatiotemporally controlled delivery of RNPs, mRNA, or DNA
