This hypothesis proposes that selective upregulation of CXCL12 in astrocytes can restore CNS immune privilege by disrupting the CCL2 chemokine gradient that drives pathogenic monocyte infiltration. Rather than depleting CCR2+ monocytes systemically, this approach targets the upstream chemotactic signals by enhancing the competing CXCL12/CXCR4 axis specifically within CNS parenchyma. Astrocytes constitutively express low levels of CXCL12, which normally contributes to maintaining CNS homeostasis
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
