Cover Story: Macroautophagy (autophagy) maintains cellular homeostasis and regulates energy production and innate immunity. The role of the human bitter taste receptors (T2Rs) in autophagy is poorly understood. This study targets T2R14, the taste receptor expressed at significant levels in oral gingival epithelial cells (GECs). Our study reveals that T2R14 downregulates autophagy protein 7 independent autophagy flux in gingival epithelial cells. Further, our results show that Streptococcus mutans quorum sensing molecule (competence stimulating peptide-1) causes robust intracellular calcium release in GECs, which is both T2R14 and autophagy protein 7 dependent. These findings reveal the different mechanisms by which T2Rs influence host-microbe interactions and modulate the oral immune environment. View this paper
