Microglia can influence neurons and other glia in culture by various non-cell autonomous mechanisms. Here, we present a protocol to selectively deplete microglia from primary neuronal cultures. This method has the potential to elucidate the role of microglial-neuronal interactions, with implications for neurodegenerative conditions where neuroinflammation is a hallmark feature.

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.

Macrophages play a central role in homeostasis and pathology in many tissues. The protocol presented here describes methods for depleting macrophages in vivo, deriving polarized macrophages from bone marrow aspirates, and adoptively transferring macrophages into mice. These techniques allow determination of the role that polarized macrophages play in health and disease.

FAQs
CSF1R inhibitors reduce microglial numbers by disrupting the survival signaling these cells require. This pharmacological route lets investigators examine brain states with substantially fewer microglia, then compare them with untreated conditions. The resulting differences can help identify processes that depend on microglia rather than reflecting direct changes in neurons, astrocytes, or infiltrating immune cells.
Genetic ablation systems provide a complementary way to remove microglia selectively, rather than relying on a CSF1R inhibitor. Using both approaches can strengthen interpretation by showing whether a finding appears across different depletion strategies. This comparison is useful when researchers need to separate consequences of microglial loss from effects associated with the particular experimental route.
Repopulation studies show what changes emerge as microglia return after depletion. Researchers can use this phase to examine whether neuroinflammation, synaptic remodeling, neuronal injury, or repair tracks with the presence of these cells. Comparing depleted and repopulating states therefore provides a dynamic view of microglial contributions, rather than only a single snapshot of their absence.
A typical experimental workflow begins with a depletion strategy, either CSF1R inhibition or selective genetic ablation, followed by analysis of brain changes and, where relevant, repopulation. Investigators compare these states with conditions in which microglia remain present. This design connects cellular removal to changes in neural processes while helping distinguish microglia-dependent effects from broader brain responses.
Key outcomes include neuroinflammation, synaptic remodeling, neuronal injury, and repair. Examining these processes after microglial reduction helps determine how each one changes with microglial presence. Interpretation should also consider neurons, astrocytes, and infiltrating immune cells, because the experimental goal is to separate microglial effects from changes involving other cellular participants in the central nervous system.
It is particularly valuable in studies of neurodegeneration, brain development, and potential brain therapies. By reducing microglial influence, investigators can test whether these cells contribute to disease-related changes, developmental processes, or repair. The approach also supports clearer interpretation of interactions among microglia, neurons, astrocytes, and infiltrating immune cells in experimentally altered brains.
