Area of Science:

  • Neuroscience
  • Biochemistry
  • Molecular Biology

Background:

  • Lipids are crucial in neurological disease pathogenesis, acting as early indicators and potential therapeutic targets.
  • Neurological diseases share hallmarks like neuroinflammation and neurodegeneration, modulated by lipid signaling pathways.
  • Understanding lipid interdependencies across brain regions is key to unraveling disease mechanisms.

Purpose of the Study:

  • To present a standardized, modular protocol for analyzing membrane lipids and associated mRNA from discrete brain regions.
  • To enable accurate comparative lipidomic profiling for neurological disease research.
  • To facilitate the identification of lipid-based biomarkers and drug targets.

Main Methods:

  • Optimized brain sampling, dissection, and co-extraction of lipids and mRNA.
  • Dual lipid/mRNA extraction followed by liquid chromatography-multiple reaction monitoring (LC/MRM) for quantification.
  • Standardized mRNA profiling and peripheral tissue/plasma lipidomic analysis.

Main Results:

  • The protocol effectively analyzes lipids and mRNA from small, discrete brain regions, minimizing bias.
  • Demonstrated applicability on an acute epilepsy mouse model for disease research.
  • Includes methods for peripheral organ and plasma lipidomics for translational studies.

Conclusions:

  • This comprehensive workflow provides a robust method for multi-regional lipid and mRNA analysis in neurological disease research.
  • The protocol supports the identification of specific lipid molecular phenotypes and morphologies linked to neurological conditions.
  • Enables the discovery of novel, translatable biomarkers and therapeutic strategies for neurological disorders.
