Dosing, collection, and quality control issues in cerebrospinal fluid research using animal models

Area of Science:

• Neuroscience
• Pharmacology
• Biomarker Discovery

Background:

• Cerebrospinal fluid (CSF) surrounds the brain and spinal cord, reflecting brain biochemistry.
• CSF biomarkers are crucial for diagnosing diseases and understanding drug pharmacokinetics/pharmacodynamics.
• Preclinical CSF studies are vital for translating findings to human applications.

Purpose of the Study:

• To review methods for preclinical CSF collection in mice, rats, and nonhuman primates.
• To summarize current techniques for direct CSF dosing in preclinical models.
• To support the use of CSF biomarkers and direct CSF drug administration in research.

Main Methods:

• Review of established and emerging techniques for CSF sampling in rodent and nonhuman primate models.
• Analysis of methods for direct administration of therapeutic agents into the CSF space.
• Synthesis of data from existing literature on preclinical CSF collection and dosing.

Main Results:

• Detailed descriptions of various CSF collection strategies tailored to different preclinical species.
• Overview of the advantages and challenges associated with direct CSF dosing.
• Identification of key considerations for successful preclinical CSF biomarker studies.

Conclusions:

• Standardized preclinical CSF collection and dosing methods are essential for reliable biomarker analysis.
• Direct CSF administration offers a targeted approach for brain drug delivery in preclinical research.
• This review provides a valuable resource for researchers utilizing CSF in preclinical drug development and biomarker studies.
