Abstract
The cellular composition of the central nervous system (CNS) is highly complex and dynamic. Regulation of this complexity is increasingly recognized to be spatially and temporally dependent during development, homeostasis and disease. Context-dependent cellular heterogeneity was shown for neuroectodermal cells as well as the myeloid compartment of the CNS. The brain myeloid compartment comprises microglia and other CNS-associated macrophages. These are brain-resident cells with critical roles in brain development, maintenance, and immune responses during states of disease. Profiling of CNS myeloid cell heterogeneity has been greatly facilitated in the past years by development of high-throughput technologies for single-cell analysis. This review summarizes current insights into heterogeneity of the CNS myeloid cell population determined by single-cell RNA sequencing and mass cytometry. The results offer invaluable insights into CNS biology and will facilitate the development of therapies for neurodegenerative and neuroinflammatory pathologies.
