Overview

Research demonstrates that HIF-1 signaling alters microglial function in heart failure, suggesting neuroinflammation drives cognitive decline.

Key Points

  • Cognitive decline is linked to microglial metabolic reprogramming in heart failure with preserved ejection fraction, revealing new therapeutic targets.
  • HIF-1 signaling activation in microglia increases glycolytic metabolism and neuroinflammation, directly affecting cognitive functions.
  • Using a murine model, conditional deletion of HIF-1 in microglia preserved cognitive performance and white matter integrity in heart failure.
  • Study identifies Sema4D as a key effector linking metabolic stress in microglia to white matter injury in heart failure.
