From Cell‐Derived Vesicles to Hybrid Nanovectors: Biological Membranes as Functional Blueprints for Gene Delivery

Advanced Healthcare Materials, EarlyView.
Biologically derived and hybrid nonviral nanovectors are examined as distinct but convergent design approaches. Integrating synthetic components with biologically functionalized membranes allows efficient interactions with complex cellular environments.

Functional loss in early age-related maculopathy: the ischaemia postreceptoral hypothesis

, 2007
We review proposed models and psychophysical and electrophysiological tests performed in many studies for early age-related maculopathy (ARM). We suggest that ischaemia is the trigger for impaired retinal pigment epithelium function causing imbalance of ...

Engineered Nanoplatforms Targeting Activated Hepatic Stellate Cells for Liver Fibrosis Therapy via TGF‐β Axis Inhibition and Ferroptosis Induction

Advanced Healthcare Materials, EarlyView.
FeS‐VA@lanifibranor (FVL), an activated hepatic stellate cell (aHSC)‐targeted nanoplatform comprising vitamin A‐functionalized two‐dimensional iron sulfide nanosheets and lanifibranor, is engineered for precision therapy of liver fibrosis. FVL suppresses the TGF‐β signaling pathway by inhibiting SMAD2/3 phosphorylation and induces ferroptosis in aHSCs,

The Fatty Acid Transporter CD36 Mediates Uptake, Biodistribution, and Cardioprotection by Small Extracellular Vesicles From HEK293 Cells

Journal of Extracellular Vesicles
Extracellular vesicles (EVs) are nanoscale carriers of bioactive molecules that mediate intercellular communication. Small EVs (sEVs) have shown cardioprotective effects in models of myocardial infarction (MI), but their uptake and biodistribution remain

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.
