Abstract Studies over the past decade have highlighted important roles played by sensory receptors outside of traditionally sensory tissues; for example, taste receptors participate in pH sensing in the cerebrospinal fluid, bitter taste receptors mediate bronchodilation and ciliary beating in the lung (Deshpande DA, Wang WC, McIlmoyle EL, Robinett KS, Schillinger RM, An SS, Sham JS, Liggett SB. Nat Med 16: 1299-1304, 2010; Shah AS, Ben-Shahar Y, Moninger TO, Kline JN, Welsh MJ. Science 325: 1131-1134, 2009), and olfactory receptors play roles in both sperm chemotaxis and muscle cell migration (Griffin CA, Kafadar KA, Pavlath GK. Cell 17: 649-661, 2009). More recently, several studies have shown that sensory receptors also play important roles in the regulation of blood pressure. This review will focus on several recent studies examining the roles that sensory receptors play in blood pressure regulation, with an emphasis on three pathways: the adenylate cyclase 3 (AC3) pathway, the Gpr91-succinate signaling pathway, and the Olfr78/Gpr41 short-chain fatty acid signaling pathway. Together, these pathways demonstrate that sensory receptors play important roles in mediating blood pressure control and that blood pressure regulation is coupled to the metabolism of the host as well as the metabolism of the gut microbiota.
