Immunomodulation With Local, Sustained Delivery of Pituitary Adenylate Cyclase Activating Polypeptide Results in Improved Functional Recovery in Stroke‐Injured Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
The tissue and functional benefits are demonstrated with local, sustained delivery of an anti‐inflammatory peptide, pituitary adenylate cyclase‐activating polypeptide (PACAP), for stroke treatment in a mouse model. Prolonged PACAP treatment modulated astrocyte and microglia toward pro‐reparative phenotypes, enhanced neuroprotection and preservation of ...

Mechanobiologically Engineered Mimicry of Extracellular Vesicles for Improved Systemic Biodistribution and Anti‐Inflammatory Treatment Efficacy in Rheumatoid Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Triblock copolymer‐reinforced liposomal mimics of extracellular vesicles are engineered with tunable membrane elasticity. A semi‐elastic formulation (Tri‐ARTEX8:2) co‐encapsulating stem cell cytosolic extract and AntagomiR155 targets inflamed joints via the ELVIS effect, reprograms macrophages from M1 to M2, and markedly alleviates collagen‐induced ...
