Multi-level transcriptional control of specific macrophage responses.

Hierarchical transcription factor networks regulate macrophage identity, activation, and responses, with secondary factors shaping stimulus-specific transcriptional programs.

• Why it matters: Understanding how transcriptional regulation controls macrophage responses is crucial because dysregulation can rewire these cells toward disease-associated states, impacting tissue health.
• What they did: The review outlines a framework where lineage-determining, tissue-specific, and signal-dependent transcription factors interact, with secondary factors modulating response magnitude, timing, and maintenance.
• The result: Deciphering these transcriptional regulators may enable targeted interventions for diseases involving macrophage dysfunction by influencing stimulus-specific gene expression.
