Inflammation’s fingerprint on the brain’s white matter
A Mendelian randomization study has uncovered causal links between specific inflammatory cytokines and microstructural changes in the brain’s white matter. Using genetic data and advanced neurite orientation dispersion and density imaging (NODDI), researchers identified that dysregulation of inflammatory factors directly influences diffusion properties in key neural pathways, including the corpus callosum and superior longitudinal fasciculus. The findings, supported by bibliometric analysis, point to microglia as a central player in this inflammation-mediated process.
Why it might matter to you:
This work provides a genetic framework linking systemic inflammation to quantifiable brain changes, a relationship central to neurodegenerative disease progression. For your focus on actionable blood-based biomarkers, it suggests that specific inflammatory profiles could serve as upstream signals for white matter integrity, potentially correlating with imaging and clinical data to track disease activity. It underscores the value of integrating inflammatory markers into a multimodal biomarker panel for more precise staging and therapeutic monitoring.
