Cascade-Type Microglial Pyroptosis Inhibitors for Enhanced Treatment of Cerebral Ischemia-Reperfusion Injury.

Neuroinflammation is a critical factor in the progression of cerebral ischemia-reperfusion injury (CIRI). Pyroptosis, which is an inflammatory form of programmed cell death, greatly amplifies neuroinflammatory processes. It does so by promoting the release of various inflammatory contents that intensify the overall inflammatory response within the central nervous system.

Engineered Extracellular Vesicle-Based Nanoformulations That Coordinate Neuroinflammation and Immune Homeostasis, Enhancing Parkinson's Disease Therapy.

Although conventional intervention to microglia can mitigate neuroinflammation in the short term, immune disorders by peripheral inflammatory cells can infiltrate continuously, resulting in an overactivated immune microenvironment of Parkinson's disease (PD). Here, we design engineered extracellular vesicle-based nanoformulations (EVNs) to address multiple factors for the management of PD. Specifically, EVN is developed by coating CCR2-enriched mesenchymal stem cell-derived extracellular vesicles (MSC EVs) onto a dihydrotanshinone I-loaded nanocarrier (MSeN-DT).
