Blocking sweet taste receptors can help body fight off sinus infections: Researchers identify amino acids that hold the key to the process -- ScienceDaily

 Bitter taste receptors in the upper airway are a first line of defense against sinus infections, but their ability to kill harmful toxins and pathogens is blocked when the sweet taste receptors are also stimulated. While glucose and other sugars are known to trigger these sweet taste receptors, researchers at the Perelman School of Medicine of the University of Pennsylvania have now shown amino acids can also have that effect. This new understanding could help pave the way toward new treatments for chronic sinus infections. The researchers published their findings in the journal Science Signaling this week."
