Use of Integrative Proteomic Analysis to Uncover Shared Molecular Signatures Across Distinct Forms of Hydrocephalus

Cross-study CSF proteomics across post-hemorrhagic, SAH, post-infectious, and iNPH links recurrently dysregulated proteins to inflammatory, TLR, BBB/coagulation, and neuronal injury signatures.

• Why it matters: Hydrocephalus is heterogeneous and common across pediatric and older populations, yet its molecular and signaling alterations are incompletely defined, limiting biomarker discovery and stratified therapy.
• What they did: They compared CSF protein profiles using published proteomic datasets across PHH, SAH, PIH, and iNPH, assessing differentially expressed proteins, shared molecular signatures, and enriched pathways.
• The result: Hemorrhage-associated forms show enriched coagulation and hemoglobin-related pathways, PIH shows enhanced immune/inflammatory responses, and iNPH shows neurodegeneration, synaptic, and impaired CSF clearance-linked changes, supporting CSF-based diagnostic stratification.
