Comparing 2 hypotheses side-by-side
Liver disease compromises BBB integrity via MMP-9 upregulation, enabling CCR2+ peripheral monocytes to infiltrate brain parenchyma and adopt IBA1-low/reactive phenotypes that phenotypically resemble microglia loss. This is the most mechanistically supported hypothesis, with documented BBB permeability in cirrhosis (PMID 29198565) and peripheral immune cell infiltration in hepatic encephalopathy (PMID 28537570). Critical validation requires Cx3cr1-CreERT2;Rosa26-tdTomato fate-mapping and stereolo
Perinatal immune activation triggers blood-brain barrier disruption facilitating monocyte infiltration and replacement of yolk-sac-derived microglia with bone marrow-derived macrophages bearing distinct transcriptomic signatures. This process involves CCR2-mediated recruitment of peripheral monocytes under inflammatory conditions (PMID: 28602351), with microglial replacement rates increasing with aging (PMID: 28604728). The resulting altered microglial population exhibits distinct inflammatory p
