Microglial Fkbp5 Impairs Post‐Stroke Vascular Integrity and Regeneration by Promoting Yap1‐Mediated Glycolysis and Oxidative Phosphorylation

Advanced Science, EarlyView.
A post‐stroke perivascular niche of microglia characterized by low expression of M2 markers and elevated glycolysis, oxidative phosphorylation (OXPHOS), and phagocytic activity is identified, which is termed stroke‐activated vascular‐associated microglia (stroke‐VAM).

Brd4 BD1 Domain Antagonism of MS436 Preserves Blood‐Brain Barrier Integrity via Rnf43/β‐Catenin Signaling Pathway

Advanced Science, EarlyView.
MS436 competitively binds to the BD1 domain of Brd4, thereby suppressing Brd4 induced degradation of tight junction proteins via the Rnf43‐Fzd4‐β‐catenin signaling pathway. Consequently, this attenuation of degradation reduces blood‐brain barrier leakage, leading to an improved overall prognosis after stroke.
