Abstract A key aspect for successful drug delivery via lipid‐based nanoparticles is their internalization in target cells. Two prominent examples of such systems are artificial phospholipid‐based carriers, as liposomes, and biological counterparts, the extracellular vesicles (EVs). Despite a wealth literature, it remains unclear which mechanisms precisely orchestrate nanoparticle‐mediated cargo to recipient cells subsequent intracellular fate therapeutic cargo. In this review, involved uptake liposomes EVs by evaluated, also exploring after trafficking. Opportunities highlighted tweak these fates enhance efficacy systems. Overall, literature date shows that both predominantly internalized through classical endocytosis mechanisms, sharing common fate: accumulation inside lysosomes. Studies tackling differences between EVs, with respect cellular uptake, therapy efficacy, remain scarce, despite its importance selection an appropriate system. addition, further exploration functionalization strategies represents important avenue pursue order control fate, thereby improving efficacy.

The rise of biologics and RNA-based therapies challenges the limitations traditional drug treatments. However, these potent new classes therapeutics require effective delivery systems to reach their full potential. Lipid nanoparticles (LNPs) have emerged as a promising solution for RNA delivery, but endosomal entrapment remains critical barrier. In contrast, natural extracellular vesicles (EVs) possess innate mechanisms overcome degradation, demonstrating superior escape (EE) compared conventional LNPs. This mini review explores EE lipid nanoparticle-based offers insights into EV advance LNP design therapeutics. We compare strategies EVs with those used in LNPs highlight contemporary approaches. By understanding EE, we will be able develop more vehicles, enhancing efficacy therapies.

The recent approval of pembrolizumab in recurrent or metastatic cervical cancer warrants further investigations into the usefulness immunotherapies for more durable and less radical interventions. In this study, targeting potential anti-PD-L1-functionalized immunoliposomes was tested a 3D vitro cancer-on-a-chip model. Immunolipsomes were synthesized decorated externally with monovalent anti-PD-L1 Fab' fragments commercially available atezolizumab. Cervical cell lines varying levels PD-L1 expression cultured as spheroids embedded collagen I matrix, treated under flow culture media. Flow cytometry live-cell confocal imaging used to measure interactions uptake untargeted liposomes panel lines. retained specific functionality regardless protein corona formation high serum environments. As such, expressing preferentially internalized environment extracellular matrix present, while low PD-L1-expressing showed no preference either formulation. Importantly, treatments performed monolayer cultures (on plastic) differences between immuno- liposome uptake, including way which endocytosed are trafficked subcellularly. This study demonstrates importance both active passive accumulation strategies achieve nanoparticle targeting. Immunoliposomes remain promising platform development targeted nanotherapies against cancers.

Abstract Radiation enteritis is the most common complication of pelvic radiotherapy, but there no effective prevention or treatment drug. Apoptotic T cells and their products play an important role in regulating inflammation maintaining physiological immune homeostasis. Here it shown that systemically infused cell‐derived apoptotic extracellular vesicles (ApoEVs) can target mice irradiated intestines alleviate radiation enteritis. Mechanistically, elevates synthesis intestinal 2′3′ cyclic GMP‐AMP (cGAMP) activates synthase (cGAS)‐stimulator interferon genes (STING) proinflammatory pathway. After systemic infusion ApoEVs, ectonucleotide pyrophosphatase phosphodiesterase 1 (ENPP1) enriches on surface ApoEVs hydrolyze cGAMP, resulting inhibition cGAS‐STING pathway activated by irradiation. Furthermore, after are phagocytosed phagocytes, ENPP1 hydrolyzed intracellular which serves as cGAMP hydrolyzation mode, thereby alleviating The findings shed light hydrolysis capacity regulation.
