Mechanistic description

Targeted viral delivery of circadian transcription factors specifically to microglia to restore cell-autonomous circadian rhythms

Mechanism / pathway

  1. ARNTL
  2. chronobiology

Evidence for (3)

  • PubMed PMID 30307084

    PMID:30307084 PubMed

  • Microglial BMAL1/ARNTL circadian clock dysfunction during neuroinflammation impairs oligodendrocyte progenitor cell recruitment and disrupts neuroimmune homeostasis, establishing a direct causal link between microglial circadian loss-of-function and neurodegeneration-relevant cellular deficits.

    PMID:40692797 2025 Front Immunol

  • Microglial BMAL1 directly regulates the Fn14 cytokine receptor, which governs activity-dependent rod-like microglial morphology and restricts neuronal activity in vivo, identifying a cell-type-specific circadian transcriptional target for microglial gene therapy.

    PMID:41615803 2026 Cell Rep

Evidence against (3)

  • Human CRY1 variants associate with attention deficit/hyperactivity disorder.

    PMID:32538895 2020 J Clin Invest

  • Importance of Bmal1 in Alzheimer's disease and associated aging-related diseases: Mechanisms and interventions.

    PMID:36056774 2022 Aging Cell

  • The Retinal Circadian Clock and Photoreceptor Viability.

    PMID:29721962 2018 Adv Exp Med Biol
