Mechanistic description

SPI1 orchestrates crosstalk between brain endothelial cells, pericytes, and microglia in response to systemic atherosclerosis, creating a neurovascular inflammatory unit. Disrupting SPI1-mediated intercellular signaling could prevent cerebrovascular disease progression to neurodegeneration.

Mechanism / pathway

  1. SPI1
  2. neuroinflammation

Evidence for (5)

  • Adult-onset CNS myelin sulfatide deficiency is sufficient to cause Alzheimer's disease-like neuroinflammation and cognitive impairment.

    PMID:34526055 2021 Mol Neurodegener

  • A novel molecular class that recruits HDAC/MECP2 complexes to PU.1 motifs reduces neuroinflammation.

    PMID:37642942 2023 J Exp Med

  • Reactive astrocytes acquire neuroprotective as well as deleterious signatures in response to Tau and Aß pathology.

    PMID:35013236 2022 Nat Commun

  • SPI1 triggers the formation of neutrophil extracellular traps in multiple sclerosis through CXCL4.
