AI Article Synopsis

  • Liposomal drug delivery for cancer therapy often faces challenges due to drugs leaking during circulation, which can reduce effectiveness.
  • Researchers created a new method that uses a stiff nanobowl embedded in the liposomal water cavity to enhance the stability of doxorubicin (DOX) and prevent this leakage.
  • This approach not only improves drug delivery to tumors but also boosts antitumor effects, making it a simpler and more effective solution compared to other methods that modify liposome surfaces.

Article Abstract

Liposomal drug delivery for cancer therapy can be limited due to drug leakage in circulation. Here, we develop a new method to enhance the stability of actively loaded liposomal doxorubicin (DOX) through embedding a stiff nanobowl in the liposomal water cavity. Nanobowl-supported liposomal DOX (DOX@NbLipo) resists the influence of plasma protein and blood flow shear force to prevent drug leakage. This approach yields improved drug delivery to tumor sites and enhanced antitumor efficacy. Compared to alternative methods of modifying liposome surface and composition for stability, this approach designs a physical support for an all-aqueous nanoliposomal cavity. Nanobowl stabilization of liposomes is a simple and effective method to improve carrier stability and drug delivery.

Extracellular vesicles (EVs) are membrane-bound vesicles that are shed or secreted from the cell membrane and enveloped by a lipid bilayer. They possess stability, low immunogenicity, and non-cytotoxicity, exhibiting extensive prospects in regenerative medicine (RM). However, natural EVs pose challenges, such as insufficient targeting capabilities, potential biosafety concerns, and limited acquisition pathways.

Erastin, as an effective ferroptosis inducer, has received extensive attention in anti-tumor research. To develop an oral nanocarrier for high efficient loading hydrophobic erastin, here we prepared a fluoro-liposome (FA-3 F-LS) by the self-assembly of the folic acid modified fluorinated amphiphiles-FA-3 F conjugates. The hydrophobic component of three perfluorooctyl chains endows the FA-3 F-LSs with high stability to resist the harsh gastrointestinal tract condition.

Functionalization of polymer nanoparticles (NPs) with targeting peptides is of interest for drug delivery applications to enhance tumor accumulation and penetration. Herein, we evaluated the feasibility of two different methods for the attachment of a tumor-penetrating peptide LinTT1 (AKRGARSTA) to poly(ethylene glycol)-block-poly(ε-caprolactone) (PCL-PEG) NPs: (1) "post-conjugation" onto pre-formed nanoparticles, and (2) "pre-conjugation", the synthesis and purification of peptide-polymer conjugates and subsequent nanoprecipitation of the conjugates diluted with non-functionalized polymers. Conjugation of the labelled peptide via maleimide-thiol chemistry was verified by gel permeation chromatography (GPC) and fluorescence measurements.

Delivery of therapies into skin is attractive for medical indications including vaccination and treatment of dermatoses but is highly constrained by the stratum corneum barrier. Microneedle (MN) patches have emerged as a promising technology to enable non-invasive, intuitive, and low-cost skin delivery. When combined with biodegradable polymer formulations, MN patches can further enable controlled-release drug delivery without injection.
