Blood-brain barrier tight junction disruption by neuroinflammatory cytokines

PARTIALLY ADDRESSED

Analyze how neuroinflammatory cascades disrupt blood-brain barrier (BBB) integrity through tight junction protein degradation. Key mechanisms to investigate: 1. TNF-alpha signaling cascade and its effects on claudin-5, occludin, and ZO-1 expression and localization 2. IL-1beta-mediated activation of MMPs (matrix metalloproteinases) that cleave tight junction proteins 3. IL-6 effects on BBB permeability and tight junction disruption 4. Therapeutic targets that could restore BBB integrity (e.g., MMP inhibitors, cytokine receptor blockers, tight junction protein stabilizers) Focus on: molecular mechanisms, therapeutic intervention points, and evidence for restoring BBB integrity in neurodegeneration.
