Circulating hs-CRP directly triggers CCR2+ monocyte recruitment to the CNS by enhancing CCL2 expression in brain endothelial cells and resident microglia through TLR4/MyD88 signaling. Once recruited, CCR2+ monocytes undergo rapid activation and begin secreting IL-1β, which creates a positive feedback loop by further stimulating microglial TLR4 receptors and promoting additional CCL2 release. This hs-CRP-initiated cascade fundamentally disrupts CNS immune privilege by establishing sustained perip
This hypothesis proposes that perinatal immune activation triggers CCR2-dependent recruitment of bone marrow-derived monocytes that replace resident microglia and undergo sustained metabolic reprogramming through the mTOR-HIF1α axis. During critical neurodevelopmental windows, pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs) activate microglial TLR4/TLR2 receptors, leading to NF-κB-mediated upregulation of CCL2 and blood-brain barrier disruption thro
