Mutation of KRAS in endothelial cells (KRAS-EC) leads to intracerebral hemorrhage (ICH) in brain arteriovenous malformations (bAVM), resulting in severe disabilities or even death. However, it is unclear what causes this hemorrhagic conversion of bAVM. Here, using a locally established, clinically-relevant sporadic bAVM mouse model, created by overexpressing mutant KRAS (KRASG12V) in the brain EC, we demonstrate that KRAS-EC act as trigger for microglia (MG) activation and infiltration of macrophages (Mϕ). Using three-dimensional immunostaining approach with cleared human and mouse bAVM tissues, we demonstrate an abundance of MG/Mϕ around the bAVM nidus. The presence of MG/Mϕ are correlated to the …
