## **Molecular Mechanism and Rationale**
The epigenetic silencing of the AIF1 (Allograft Inflammatory Factor 1) gene locus represents a novel mechanistic pathway linking chronic systemic inflammation to persistent neuroinflammatory dysfunction. AIF1 encodes IBA1 (Ionized calcium-Binding Adapter molecule 1), a critical protein exclusively expressed in microglia and macrophages that regulates phagocytosis, motility, and inflammatory responses. Under physiological conditions, AIF1 transcription is
**Molecular Mechanism and Rationale**
The proposed mechanism centers on liver disease-induced breakdown of blood-brain barrier (BBB) integrity through matrix metalloproteinase-9 (MMP-9) upregulation, facilitating CCR2+ peripheral monocyte infiltration into brain parenchyma where they adopt altered phenotypes that mimic microglial dysfunction. In healthy conditions, the BBB maintains strict control over immune cell trafficking through tight junction proteins including claudin-5, occludin, and zo
