Implication

Experimental treatments improved cerebral blood flow in sickle cell disease by boosting regulatory T cells, suggesting potential immunomodulatory therapies.

Key Points

To explore the therapeutic effects of T-regulatory cells on cerebral vasculopathy in sickle cell disease.
Infused ferric heme in sickle cell disease mice models.
Measured cerebral blood flow using magnetic resonance angiography.
Administered IL-2 antibody complexes for Treg enhancement.
Monitored cerebrovascular changes via two-photon laser scanning microscopy.
Regulatory T cells significantly reduced post-heme challenge in mice brains.
Cerebral blood flow decreased with Treg reduction and increased with Treg accumulation.
Treg treatment resulted in improved cerebrovascular integrity and reduced thrombogenesis.
