Neutrophil elastase (NE) is a protease released by activated neutrophils in the brain parenchyma after cerebral ischemia, which plays a pivotal role in the regulation of neutrophil extracellular traps (NETs) formation. The excess NETs could lead to blood-brain barrier (BBB) breakdown, overwhelming neuroinflammation, and neuronal injury. While the potential of targeting neutrophils and inhibiting NE activity to mitigate ischemic stroke (IS) pathology has been recognized, effective strategies that inhibit NETs formation remain under-explored. Herein, a biomimic multifunctional nanoplatform (HM@ST/TeTeLipos) was developed for active NE targeting and IS treatment. The core of the HM@ST/TeTeLipos consisted of sivelestat-loaded ditelluride-containing liposomes with ROS-responsive and NE-inhibiting properties. The outer shell was composed of platelet-neutrophil hybrid membrane vesicles (HMVs), which acted to hijack neutrophils and neutralize proinflammatory cytokines. Our studies revealed that HM@ST/TeTeLipos could effectively inhibit NE activity, thereby suppressing the release of NETs, impeding the activation of the AIM2 inflammasome, and consequently redirecting the immune response away from a pro-inflammatory M1 microglia phenotype. This resulted in enhanced neurovascular remodeling, reduced BBB disruption, and diminished neuroinflammation, ultimately promoting neuron survival. We believe that this innovative approach holds significant potential for improving the treatment of IS and various NE-mediated inflammatory diseases.
