Silencing of TGFβ signalling in microglia results in impaired homeostasis

Abstract

While previous studies had shown the requirement of TGFβ signalling in microglia gene expression, the specificity of the loss-of-function was unclear. Here, Zöller and colleagues generate microglia specific cKO of TGFβ receptor 2, and show dispensable function of Tgfbr2 in microglial survival and the requirement of Tgfbr2 in morphological and transcriptional homeostasis of adult microglia.
