Rod‐shaped Polymerized Salicylic Acid Particles Modulate Neutrophil Transendothelial Migration in Acute Inflammation

Advanced Healthcare Materials, EarlyView.
Rod‐shaped particles outperform spherical particles of the same volume in preventing neutrophil infiltration to inflamed areas, both in vitro and in vivo. This therapeutic effectiveness is attributed to better cell targeting and decreased cell motility, resulting from the geometry‐driven phagocytosis and inhibited actin polymerization.

Encapsulation of Small Extracellular Vesicles into Selectively Disassemblable Shells of PEGylated Metal‐Phenolic Networks

Advanced Healthcare Materials, EarlyView.
Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

Engineered Chitosan‐Derived Nanocarrier for Efficient siRNA Delivery to Peripheral and Central Neurons

Advanced Healthcare Materials, EarlyView.
This study introduces a novel chitosan‐based nanocarrier functionalized with a neurotropic protein for efficient siRNA delivery to neurons. The polyplexes demonstrate enhanced neuronal binding, retrograde transport, and PTEN silencing, promoting axonal outgrowth.

Carbon‐Based Flexible Electrode for Efficient Electrochemical Generation of Reactive Chlorine Species in Tumor Therapy

Advanced Healthcare Materials, EarlyView.
A flexible electrode loaded with a carbon nanowire network (CC@C‐NWN) is developed for electrochemically generating reactive chlorine species (RCS) from abundant chloride ions in body fluids for tumor therapy. CC@C‐NWN enhances chlorine evolution, inducing redox dysregulation and synergistic apoptosis‐ferroptosis in tumor cells.

Intracellular membrane fusion

Trends in Biochemical Sciences, 1991
Protein trafficking and membrane assembly are accomplished in eukaryotes by the specific targeting and fusion of vesicles. In this review we describe some of the molecules implicated as components of the fusion apparatus, and evidence that suggests the same factors are recruited for a variety of intracellular fusion events.

Regulation of intracellular membrane transport

Current Opinion in Cell Biology, 1992
A number of proteins that are necessary for membrane transport have been identified using cell-free assays and yeast genetics. Although our knowledge of transport mechanisms remains limited, common themes are clearly emerging. In particular, specific GTP-binding proteins appear to be involved, not only at all steps of membrane traffic but also at more ...

Intracellular membrane fusion

Current Opinion in Cell Biology, 1989
One of the most intriguing properties of cellular membranes is their ability to fuse with one another. Within a living cell numerous membrane fusion and fission events occur, mediating the flow of cellular constituents between different cell organelles. How do two adhering membranes achieve this complex merging operation within the restriction posed by

Membrane tethering in intracellular transport

Current Opinion in Cell Biology, 1999
Studies of various membrane trafficking steps over the past year indicate that membranes are tethered together prior to the interaction of v-SNAREs and t-SNAREs across the membrane junction. The tethering proteins identified to date are quite large, being either fibrous proteins or multimeric protein complexes.
