We outline methods for the efficient and quick isolation/culture of viable microglia from the neonatal cerebral cortex and adult spinal cord. The dissection and plating of cortical microglia can be accomplished within 90 minutes, with the subsequent microglial harvest taking place ~ 10 days following the initial dissection.

The video demonstrates a technique for isolating microglia from the cortex of an adult mouse brain. First, the cortex undergoes segmentation and homogenization to remove neurons and other glial cells, preserving microglia. Following that, the cell suspension is exposed to anti-myelin magnetic microbeads and a magnetic field, effectively separating microglia and myeloid cells from myelin debris and cells containing myelin.

Microglia are resident macrophages that provide the first line of defense and immune surveillance of the central nervous system. MicroRNAs are regulatory molecules that play an important role in many physiological processes including activation and differentiation of macrophages. In this article, we describe the method for measurement of microRNAs in microglia.

FAQs
Pattern-recognition receptors allow adult microglia to detect pathogen-associated signals from infectious agents and damage-associated signals from injured tissue. Recognition initiates coordinated changes rather than a single reaction: the cells can alter morphology, migrate toward affected regions, and release cytokines, chemokines, and other mediators. These events help regulate local inflammation and phagocytosis.
Morphological change and directed migration help adult microglia respond spatially to problems within the central nervous system. Cells can move toward affected regions, positioning their regulatory and phagocytic activities where infection or injury occurs. This localization supports containment and tissue responses, while the mediators they release influence neighboring cells and the broader inflammatory environment.
Adult microglia communicate with neurons, astrocytes, and infiltrating leukocytes as part of a multicellular immune response. These interactions connect local pathogen or damage sensing with regulation of inflammation, phagocytosis, blood-brain barrier integrity, and tissue repair. Consequently, microglial activity can influence both neural homeostasis and how other immune or neural cells respond to disease-related signals.
A useful investigation can examine several linked outcomes: altered morphology, movement toward affected regions, production of cytokines and chemokines, release of other inflammatory mediators, and phagocytic activity. Assessing these features together helps distinguish detection from downstream response and shows how microglia may contribute to infection containment, inflammatory regulation, or tissue repair within the central nervous system.
They provide a cellular connection between pathogen detection and the tissue-level response to infection. By sensing pathogen-associated signals, changing their behavior, releasing immune mediators, and regulating phagocytosis, adult microglia can help contain infectious threats. Their communication with neural and immune cells also makes them relevant for understanding how infection affects neural homeostasis and barrier integrity.
Microglial responses are beneficial when they help contain infection and support repair, but persistent or dysregulated activity can alter the inflammatory environment over time. Because adult microglia interact with neurons, astrocytes, leukocytes, and the blood-brain barrier, prolonged signaling may influence several connected processes. Studying these responses helps explain links between neuroinflammation and neurological disease.
