TLDR
A historical perspective of work to identify microglia function in the healthy CNS is given and exciting new work in the field that has identified roles for these cells in CNS development, maintenance, and plasticity is highlighted.Abstract:
The nervous system comprises a remarkably diverse and complex network of different cell types, which must communicate with one another with speed, reliability, and precision. Thus, the developmental patterning and maintenance of these cell populations and their connections with one another pose a rather formidable task. Emerging data implicate microglia, the resident myeloid-derived cells of the central nervous system (CNS), in the spatial patterning and synaptic wiring throughout the healthy, developing, and adult CNS. Importantly, new tools to specifically manipulate microglia function have revealed that these cellular functions translate, on a systems level, to effects on overall behavior. In this review, we give a historical perspective of work to identify microglia function in the healthy CNS and highlight exciting new work in the field that has identified roles for these cells in CNS development, maintenance, and plasticity.read more

TL;DR: The analysis of RNA expression patterns of more than 76,000 individual microglia in mice during development, in old age, and after brain injury uncovered at least nine transcriptionally distinct microglial states, which expressed unique sets of genes and were localized in the brain using specific markers.

Resting Microglial Cells Are Highly Dynamic Surveillants of Brain Parenchyma in Vivo
TL;DR: Using in vivo two-photon imaging in neocortex, it is found that microglial cells are highly active in their presumed resting state, continually surveying their microenvironment with extremely motile processes and protrusions.

TL;DR: The authors' data provide clues as to how neurons and astrocytes differ in their ability to dynamically regulate glycolytic flux and lactate generation attributable to unique splicing of PKM2, the gene encoding the glycoleytic enzyme pyruvate kinase.

TL;DR: These cell lineages range in length from one to eight sequential divisions and lead to significant developmental changes in the neuronal, muscular, hypodermal, and digestive systems and are determined by direct observation of the divisions, migrations, and deaths of individual cells in living nematodes.
