Published: Feb. 12, 2024

Abstract Ischemic stroke is a dreadful vascular disorder that poses enormous threats to the public health. Due its complicated pathophysiological features, current treatment options after ischemic attack remains unsatisfactory. Insufficient drug delivery lesions impeded by blood–brain barrier (BBB) largely limits therapeutic efficacy of most anti‐stroke agents. Herein, inspired rapid BBB penetrability 4T1 tumor cells upon their brain metastasis and natural roles platelet in targeting injured vasculatures, bio‐derived nanojacket developed fusing cell membrane with membrane, which further clothes on surface paeonol polymetformin‐loaded liposome obtain biomimetic nanoplatforms (PP@PCL) for treatment. The designed PP@PCL could remarkably alleviate ischemia‐reperfusion injury efficiently lesion, preventing neuroinflammation, scavenging excess reactive oxygen species (ROS), reprogramming microglia phenotypes, promoting angiogenesis due synergistic mechanisms anchor characteristics stroke. As result, exerts desirable PC12 neuronal rat model stroke, significantly attenuates apoptosis, reduces infarct volume, recovers neurological functions, bringing new insights into exploiting promising strategies cerebral management.

Metformin-based nanomedicines for reprogramming tumor immune microenvironment

Theranostics, Journal Year: 2024, Volume and Issue: 15(3), P. 993 - 1016

Published: Dec. 2, 2024

Immunotherapy has transformed current cancer management, and it achieved significant progress over last decades. However, an immunosuppressive tumor microenvironment (TME) diminishes the effectiveness of immunotherapy by suppressing activity immune cells facilitating immune-evasion. Adenosine monophosphate-activated protein kinase (AMPK), a key modulator cellular energy metabolism homeostasis, gained growing attention in anti-tumor immunity. Metformin is usually considered as cornerstone diabetes its role activating AMPK pathway also been extensively explored therapy although findings on remain inconsistent. nanomedicine formulation found to hold potential reprogramming TME through immunometabolic modulation both cells. This review elaborates foundation via metformin-based nanomedicines, offering valuable insights for next generation therapy.
