Human Hearts taste bitter

bittaWissenschaftler haben 12 unterschiedliche Geschmacksrezeptoren im Herzen gefunden, alle mehr oder weniger zuständig für bitteren Geschmack. Oder um's wie Scott Alexander zu formulieren: „This wins my prize for 'most unintentionally poetic medical headline'“: Researchers find bitter taste receptors on human hearts. Vielleicht finden sie ja auch noch ein paar Süßigkeits-Rezeptoren für Sweethearts.

This is quite remarkable, as the human genome only has 25 of these bitter taste receptors, and we wanted to find out why half of them were located in the heart.

"When we activated one of the taste receptors with a specific chemical that we all taste as bitter, the contractile function of the heart was almost completely inhibited. While the underlying physiology behind this phenomenon remains unclear, this is now a major area of ongoing investigation."
