Mechanistic description

SPI1 directly regulates C1Q expression in brain microglia, creating a feed-forward loop that amplifies neuroinflammation in cerebrovascular disease. Selective inhibition of SPI1 binding to C1Q promoter regions could break this pathological circuit while preserving beneficial microglial functions.

Mechanism / pathway

  1. SPI1
  2. neuroinflammation
