abstract = {Microglia and central nervous system (CNS)-associated
macrophages (CAMs), such as perivascular and meningeal
macrophages, are implicated in virtually all diseases of the
CNS. However, little is known about their cell-type-specific
roles in the absence of suitable tools that would allow for
functional discrimination between the ontogenetically
closely related microglia and CAMs. To develop a new
microglia gene targeting model, we first applied massively
parallel single-cell analyses to compare microglia and CAM
signatures during homeostasis and disease and identified
hexosaminidase subunit beta (Hexb) as a stably expressed
microglia core gene, whereas other microglia core genes were
substantially downregulated during pathologies. Next, we
generated HexbtdTomato mice to stably monitor microglia
behavior in vivo. Finally, the Hexb locus was employed for
tamoxifen-inducible Cre-mediated gene manipulation in
microglia and for fate mapping of microglia but not CAMs. In
sum, we provide valuable new genetic tools to specifically
study microglia functions in the CNS.},
