Microglial LXRβ Inactivation in Early Mice Linked to Cognitive Dysfunction

Quick Summary

• The study referenced in the proceedings of the National Academy of Sciences, Volume 122, Issue 15 (April 2025), focuses on microglia, immune cells in the brain that manage neuroinflammation by eliminating foreign substances and pruning synapses.
• Researchers discovered that early ablation (removal) of LXRβ in postnatal microglia leads to reduced microglial function, potentially impacting cognitive abilities and synaptic health.
• The implications of this research highlight links between cellular-level changes in the brain and long-term cognitive outcomes.
