Stroke research at the crossroads - where are we heading?

Area of Science:

• Neurology
• Immunology
• Regenerative Medicine

Background:

• Stroke is the second leading cause of death globally, resulting in significant disability and increasing healthcare costs.
• Limited therapeutic options and the failure of neuroprotective strategies highlight the need for new approaches.
• The aging population exacerbates the incidence and economic burden of stroke.

Purpose of the Study:

• To review emerging fields in translational stroke research beyond early neuroprotection.
• To explore the role of neuroinflammation and the immune system in stroke pathophysiology and comorbidities.
• To discuss mechanisms and therapeutic strategies for promoting regeneration and neuronal plasticity after stroke.

Main Methods:

• Review of recent experimental and translational research in stroke.
• Analysis of the interplay between the immune system and the injured brain.
• Discussion of regeneration and plasticity mechanisms, clinical imaging, and therapeutic interventions.

Main Results:

• Neuroprotection strategies have largely failed in clinical trials, prompting a shift in research focus.
• The immune system plays a dual role in stroke: influencing brain tissue fate and contributing to comorbidities.
• Regeneration and neuronal plasticity are identified as promising targets for future stroke therapies.

Conclusions:

• A paradigm shift is occurring in stroke research, moving towards delayed mechanisms.
• Understanding the immune response and promoting brain plasticity are crucial for developing effective stroke treatments.
• Future research should focus on harnessing regenerative processes and managing stroke-associated comorbidities.
