Hollow Prussian Blue Nanozymes Drive Neuroprotection against Ischemic Stroke via Attenuating Oxidative Stress, Counteracting Inflammation, and Suppressing Cell Apoptosis
Abstract
Abstract Ischemic stroke is a devastating disease and one of the leading causes of mortality worldwide. Overproduction of reactive oxygen and nitrogen species (RONS) following ischemic insult is known as a key factor in exacerbating brain damage. Thus, RONS scavengers that can block excessive production of RONS have great therapeutic potential. Herein, we propose an efficient treatment strategy in which an artificial nanozyme with multienzyme activity drives neuroprotection against ischemic stroke primarily by scavenging RONS. Specifically, through a facile, Bi3+-assisted, template-free synthetic strategy, we developed hollow Prussian blue nanozymes (HPBZs) with multienzyme activity to scavenge RONS in a rat model of ischemic stroke. The comprehensive characteristics of HPBZs against RONS were explored. Apart from attenuating oxidative stress, HPBZs also suppressed apoptosis and counteracted inflammation both in vitro and in vivo, thereby contributing to increased brain tolerance of ischemic injury with minimal side effects. This study provides a proof of concept for a novel class of neuroprotective nanoagents that might be beneficial for treatment of ischemic stroke and other RONS-related disorders.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
