Area of Science:

  • Neuroscience
  • Immunology
  • Cell Biology

Background:

  • Microglia are essential for central nervous system (CNS) homeostasis and inflammation.
  • Primary microglia are superior to cell lines for in vitro studies of microglial biology.
  • Existing methods for isolating primary microglia are inefficient and time-consuming.

Purpose of the Study:

  • To develop a quick, easy, and efficient protocol for isolating primary microglia from neonatal mouse brains.
  • To provide researchers with a reliable method for obtaining high-purity primary microglia for in vitro investigations.

Main Methods:

  • The protocol involves brain dissection, primary brain cell culture, and microglia isolation.
  • This method is designed to be straightforward and accessible for researchers.

Main Results:

  • The developed protocol successfully isolates primary microglia with high purity.
  • Isolated primary microglia demonstrate retained immune function, responding to lipopolysaccharide challenges.

Conclusions:

  • A simplified and efficient method for isolating primary microglia has been established.
  • This protocol facilitates extensive in vitro investigations into microglial biology and CNS inflammatory processes.
