설치류에 살아서 Stereotaxic 외과

Executive Industry Relevance

Survivable stereotaxic surgery in rodents enables precise implantation of guide cannulas and microdialysis probes for in vivo measurement of extracellular neurotransmitter levels. This capability is critical for interrogating CNS pharmacodynamics, supporting target validation, and de-risking mechanistic hypotheses in neuropsychiatric and neurodegenerative drug discovery. The approach provides high anatomical and chemical resolution, facilitating translational continuity from early discovery through preclinical research.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct measurement of neurotransmitter dynamics in response to pharmacological or physiological challenges.
• Supports functional validation of CNS targets by linking compound action to neurochemical changes in specific brain regions.
• Facilitates mechanistic de-risking by allowing site-specific drug delivery and response assessment.

Screening & Assay Development

• Prepares validated rodent models for quantitative neurochemical assays using microdialysis and HPLC-EC.
• Enables reproducible, standardized sampling of extracellular neurotransmitters for downstream compound evaluation.
• Supports assay scalability and platform reuse across multiple CNS targets and pathways.

Translational & Preclinical Research

• Aligns in vivo neurochemical readouts with disease-relevant endpoints for translational biomarker development.
• Provides continuity from discovery-stage mechanistic studies to preclinical efficacy and safety models.
• Enables risk-adjusted advancement decisions based on quantitative neurochemical data.
