How does HDAC1/2 deletion specifically enhance microglial amyloid phagocytosis capacity?

PARTIALLY ADDRESSED

While the study shows HDAC1/2 deletion improves amyloid clearance and cognition, the specific epigenetic and transcriptional changes that enhance phagocytic function are not mechanistically defined. This knowledge gap limits translation to targeted therapeutic approaches.
