PG - 243-265 LID - 10.1007/978-1-4939-9658-2_18 [doi] AB - Genetically encoded calcium indicators (GECIs) have become widely used for Ca(2+) imaging in cultured cells as well as in living organisms. Transduction of microglia with viral vectors encoding GECIs provides a convenient means to label microglia for in vivo Ca(2+) imaging. We describe a method using microglia-specific microRNA-9-regulated viral vector, to label microglial cells with a ratiometric GECI (Twitch-2B). This method enables longitudinal recording of both transient and sustained elevations of Ca(2+) in microglia in live animals.
