Area of Science:

  • Neurology
  • Biomedical Engineering
  • Nanotechnology

Background:

  • Ischemic stroke, a leading cause of neurological disability, is challenging to treat due to limitations in conventional drug delivery.
  • Current therapies like thrombolysis and neuroprotection lack targeted delivery systems, hindering efficacy.
  • The brain's pathological microenvironment post-stroke (hypoxia, acidity, inflammation) presents opportunities for targeted interventions.

Purpose of the Study:

  • To review the pathological microenvironment of ischemic stroke and current treatment strategies.
  • To highlight stimulus-responsive materials for developing targeted nano-delivery systems.
  • To discuss the application of microenvironment-responsive nanosystems in regulating the ischemic cerebral environment.

Main Methods:

  • Literature review focusing on ischemic stroke pathology and therapeutic strategies.
  • Analysis of stimulus-responsive materials and their application in nanosystems.
  • Discussion of nanosystem-based microenvironment regulation for stroke treatment.

Main Results:

  • The pathological microenvironment of ischemic stroke offers unique targets for drug delivery.
  • Various stimulus-responsive materials can be utilized to create targeted nanosystems.
  • Microenvironment-responsive nanosystems show potential for enhanced drug delivery and therapeutic effects in ischemic stroke.

Conclusions:

  • Microenvironment-responsive nanosystems represent a promising frontier for ischemic stroke treatment.
  • Targeted drug delivery to the ischemic brain can be achieved by leveraging the pathological microenvironment.
  • Further research into these nanosystems could lead to more effective therapies for ischemic stroke.
