Topology‐Encoded Charge Polarity Governs Multiphase Organization in Intrinsically Disordered Protein Polymer Condensates

Small, EarlyView.
Electrostatic topology is shown to program phase separation and internal organization in thermoresponsive intrinsically disordered protein polymer (IDPP) condensates. By comparing oppositely charged IDPPs with a covalent diblock, chain connectivity is revealed to control charge compensation, dense‐phase micropolarity, miscibility, and apparent acid ...

Modulation of Growth Factor Receptors in Membrane Microdomains

YAKUGAKU ZASSHI, 2012
Membrane lateral heterogeneity is accepted as a requirement for the function of biological membranes, and the notion of the "raft/microdomain" gives specificity to this concept. Recently, fluorescence-based techniques such as fluorescence recovery after photobleaching (FRAP), single particle tracking (SPT), and fluorescence correlation spectroscopy ...

Precisely Engineering Biomimetic Nanoparticles via Controlled Cell Membrane Coating

Small, EarlyView.
Precise engineering of cell membrane‐coated nanoparticles (CMNPs) requires coordinated control over particle size, coating integrity, and membrane leaflet orientation. This review integrates key synthesis parameters, assembly strategies, and analytical methods that govern these features, revealing how structural control underpins biomimetic function ...

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, EarlyView.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Targeting the CD47–SIRPα phagocytic checkpoint in cancer: Biology, translational opportunities, and next‐generation therapeutic strategies

Smart Molecules, EarlyView.
The CD47–SIRPα axis has emerged as a critical innate immune checkpoint that suppresses macrophage‐mediated phagocytosis through a canonical “don't eat me” signal and enables tumor immune evasion. We comprehensively summarize the structural and biological features of CD47 and the molecular mechanisms underlying CD47‐mediated regulation of phagocytosis ...

Membrane Microdomains, Rafts, and Detergent-Resistant Membranes in Plants and Fungi

, 2013
The existence of specialized microdomains in plasma membranes, postulated for almost 25 years, has been popularized by the concept of lipid or membrane rafts.

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

Smart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their

A pH‐Responsive fluorescence lifetime probe reveals GOT1 phase separation in cellular anti‐senescence

Smart Molecules, EarlyView.
Acidic pH triggers GOT1 phase separation via IDR1, recruiting ME1 to form ROS‐scavenging condensates that combat senescence, revealed by a FLIM‐based pH probe. Abstract Cellular senescence involves progressive acidification, but how cells sense and adapt to this pH shift remains unclear.

Proximity Proteomics Maps Candidate Cellular Uptake Pathways for Cell‐Derived Nanovesicles

Small Methods, EarlyView.
TurboID‐based dual‐sided proteomics compares mechanically generated cell‐derived nanovesicles with naturally secreted small extracellular vesicles. Vesicle proteomes define candidate interaction signatures, while recipient‐cell proximity labelling identifies exposure‐associated proteins.
