Mechanistic description

After acute cerebrovascular events, persistent SPI1 activity maintains microglia in pro-inflammatory states that inhibit synaptic plasticity and neural repair. Time-limited SPI1 inhibition during recovery windows could shift microglia toward repair-promoting phenotypes and enhance neuroplasticity.

Mechanism / pathway

  1. SPI1
  2. neuroinflammation
