Regulatory T lymphocytes as a therapy for ischemic stroke

Area of Science:

• Neuroscience
• Immunology
• Regenerative Medicine

Background:

• Excessive inflammation following ischemic stroke worsens brain injury and hinders recovery.
• Regulatory T (Treg) cells (CD4+CD25+Foxp3+) are crucial for suppressing inflammation and restoring immune balance post-stroke.

Purpose of the Study:

• To review the neuroprotective and reparative functions of Treg cells in ischemic stroke.
• To explore the cellular and molecular mechanisms underlying Treg cell activity.
• To discuss Treg cell-based therapeutic strategies for stroke.

Main Methods:

• Literature review of recent findings on Treg cells in ischemic stroke.
• Analysis of Treg cell-mediated mechanisms, including cell-cell interactions and soluble factors.
• Examination of Treg cell expansion strategies tested in stroke models.

Main Results:

• Treg cells demonstrate neuroprotective effects in the acute stroke phase.
• Treg cells promote brain repair during chronic stroke phases.
• Treg cells target various immune and non-immune central nervous system cells.

Conclusions:

• Treg cells possess significant protective and reparative properties, making them suitable for immune therapy.
• Expanding Treg cell numbers and function is a developing therapeutic strategy for stroke.
• Treg cell expansion approaches show potential for future stroke patient treatment.
