Neutrophil membrane-camouflaged nanoparticles alleviate inflammation and promote angiogenesis in ischemic myocardial injury.

ABSTRACT: Acute myocardial infarction (AMI) induces a sterile inflammatory response, leading to cardiomyocyte damage and adverse cardiac remodeling. Interleukin-5 (IL-5) plays an essential role in developing eosinophils (EOS), which are beneficial for the resolution of inflammation. Furthermore, the proangiogenic properties of IL-5 also contribute to tissue healing following injury. Therefore, targeted delivery of IL-5 is an innovative therapeutic approach for treating AMI. It has been shown that conventional IL-5 delivery can result in undesirable adverse effects and potential drug overdose. In this study, we successfully synthesized a biomimetic IL-5 nanoparticle by camouflaging the IL-5 nanoparticle in a neutrophilic membrane. The administration of neutrophil membrane-camouflaged nanoparticles (NM-NP_IL-5) in the in vivo model showed that these nanoparticles promoted EOS accumulation and angiogenesis in the infarcted myocardium, thereby limiting adverse cardiac remodeling after AMI. Our results also demonstrated that the NM-NP_IL-5 could serve as neutrophil "decoys" to adsorb and neutralize the elevated neutrophil-related cytokines in the injured heart by inheriting multiple receptors from their "parent" neutrophils. Finally, the targeted delivery of NM-NP_IL-5 protected the cardiomyocytes from excessive inflammatory-induced apoptosis and maintained cardiac function. Our findings provided a promising cardiac detoxification agent for acute cardiac injury.

Project description:Background:Melanoma is the most common symptom of aggressive skin cancer, and it has become a serious health concern worldwide in recent years. The metastasis rate of malignant melanoma remains high, and it is highly difficult to cure with the currently available treatment options. Effective yet safe therapeutic options are still lacking. Alternative treatment options are in great demand to improve the therapeutic outcome against advanced melanoma. This study aimed to develop albumin nanoparticles (ANPs) coated with macrophage plasma membranes (RANPs) loaded with paclitaxel (PTX) to achieve targeted therapy against malignant melanoma. Methods:Membrane derivations were achieved by using a combination of hypotonic lysis, mechanical membrane fragmentation, and differential centrifugation to empty the harvested cells of their intracellular contents. The collected membrane was then physically extruded through a 400 nm porous polycarbonate membrane to form macrophage cell membrane vesicles. Albumin nanoparticles were prepared through a well-studied nanoprecipitation process. At last, the two components were then coextruded through a 200 nm porous polycarbonate membrane. Results:Using paclitaxel as the model drug, PTX-loaded RANPs displayed significantly enhanced cytotoxicity and apoptosis rates compared to albumin nanoparticles without membrane coating in the murine melanoma cell line B16F10. RANPs also exhibited significantly higher internalization efficiency in B16F10 cells than albumin nanoparticles without a membrane coating. Next, a B16F10 tumor xenograft mouse model was established to explore the biodistribution profiles of RANPs, which showed prolonged blood circulation and selective accumulation at the tumor site. PTX-loaded RANPs also demonstrated greatly improved antitumor efficacy in B16F10 tumor-bearing mouse xenografts. Conclusion:Albumin-based nanoscale delivery systems coated with macrophage plasma membranes offer a highly promising approach to achieve tumor-targeted therapy following systemic administration.
