REV-ERB-alpha and beta together control how support brain cells respond and manage protein balance

Updated

Abstract

Inducible postnatal global deletion of both REV-ERB-α and -β leads to extensive transcriptional changes in the brain related to neurodegenerative pathways.

  • Global deletion of REV-ERB-α and -β reveals significant changes in pathways associated with protein breakdown, immune response, and oxidative stress.
  • Spontaneous activation of astrocytes occurs following the global deletion of both REV-ERB receptors.
  • Astrocyte-specific deletion of REV-ERB-α and -β also results in increased , indicating a cell-specific regulatory role.
  • REV-ERB-α and -β are shown to repress certain genes related to astrocyte activation, with their deletion increasing STAT3 expression.
  • Dual deletion of REV-ERBs enhances the uptake and degradation of alpha-synuclein in astrocytes and reduces associated pathology in a Parkinson's Disease model.
