Area of Science:

  • Nanotoxicology
  • Cell Biology
  • Immunology

Background:

  • Immortalized cell lines are commonly used in nanotoxicology but yield results inconsistent with primary cells.
  • Kupffer cells, liver macrophages, are vital for nanoparticle clearance via the reticulo-endothelial system.
  • Discrepancies in toxicity data necessitate the use of primary cells for more accurate in vitro assays.

Purpose of the Study:

  • To describe a protocol for isolating high-purity mouse Kupffer cells.
  • To demonstrate the utility of isolated Kupffer cells in nanoparticle toxicity testing.
  • To provide a practical and efficient model for nanotoxicological studies.

Main Methods:

  • A 2-step liver perfusion method followed by density gradient purification was employed.
  • The protocol is adapted from rat liver cell isolation, utilizing collagenase digestion and density centrifugation.
  • High yield (up to 14 x 10^6 cells/mouse) and purity (>95%) of Kupffer cells were achieved.

Main Results:

  • The isolation method is cost-effective and does not require specialized equipment.
  • Using heavier mice (35-45g) improved cell yield and facilitated surgical procedures.
  • Functionalized carbon nanotube (f-CNT) toxicity was consistently measured using the lactate dehydrogenase (LDH) assay on isolated Kupffer cells.

Conclusions:

  • Isolated mouse Kupffer cells provide a robust and reproducible model for in vitro nanotoxicology.
  • This method enhances the reliability of nanoparticle toxicity assessments.
  • Utilizing Kupffer cells can improve the efficiency of selecting nanoparticles for clinical applications.
